Hepatocellular Carcinoma Clinical Trial Timeline: In-depth Research Report

Coverage: 42 landmark trials cited in NCCN Hepatobiliary V1.2026 (all PMID-traceable) + etiology (HBV/HCV/MASH) stratification + China-led research ecosystem + the unique dilemma of zero-predictive-biomarker approvals

Curated by Dual Brain Lab (csilab.net)

1. One-sentence definition

This report traces the evolution logic and current decision landscape of hepatocellular carcinoma (HCC) systemic therapy over the past 18 years (2008-2026), built on landmark clinical trials cited in NCCN Hepatobiliary Cancers V1.2026 — providing frontline clinicians a traceable panoramic map for “who, what, and on what evidence” decisions at the 2026 timepoint.

Iron rule: every data point from every trial is traceable to PubMed (PMID) or ClinicalTrials.gov (NCT id) — each [PMID xxxxxxxx] in the text can be clicked open on PubMed to verify the original paper.

HCC’s uniqueness concentrates in one contrast: NSCLC has 10+ predictive biomarkers (EGFR / ALK / ROS1 / KRAS / MET / HER2 / RET / BRAF / NTRK / PD-L1 TPS), BTC has 9 approved biomarkers (FGFR2 / IDH1 / HER2 / BRAF / NTRK / RET / MSI-H / TMB-H / claudin 18.2), PDAC has opened three paths (KRAS G12C / G12D / pan-KRAS) — yet HCC systemic therapy has zero approved predictive biomarkers to date. TERT (promoter mutation ~60%), TP53 (~30%), CTNNB1 (~30%) are the three main drivers but none are druggable; MET amplification and FGF19 amplification have low prevalence and phase III trials (COSMIC-312 / LEAP-002) failed. Clinical stratification relies on Child-Pugh (liver function) + BCLC (Barcelona Clinic Liver Cancer staging) + AFP (alpha-fetoprotein) + etiology (HBV/HCV/MASH) + tumor burden — all clinical parameters, no molecular biomarker.

2. Longitudinal: Evolution timeline of five treatment paradigms

HCC systemic therapy has gone through five paradigm shifts over the past 18 years: sorafenib solo for a decade (2008-2017) → multi-TKI 2L and 1L non-inferiority (2017-2019) → IO + anti-angiogenic rewriting 1L (2020-2024, four-way standoff) → the “zero predictive biomarker” precision dilemma surfaces → perioperative / adjuvant push but the first phase III long-term follow-up reversed (2023-2026).

Every shift had 1-3 phase III trials as fulcrum. Compared to NSCLC’s 5 shifts in 25 years driven by the “driver gene + immunotherapy dual-wheel” model, HCC’s evolution is characterized by “the IO backbone holding up the entire field without biomarker support” — in 2026 all four positive 1L IO combinations (atezo+bev / STRIDE / nivo+ipi / cam+rivo) achieved OS benefit in unstratified populations, with PD-L1 / TMB / MSI failing to predict response. This differs entirely from NSCLC’s path of EGFR → PD-L1 TPS stratification → combos.

2.1 The sorafenib solo era (2008-2017): one drug holding up ten years

SHARP in 2008 produced mOS 10.7 vs 7.9 months (HR 0.69) in a globally Caucasian / HCV-dominant population; in the same year the Asia-Pacific sorafenib study reproduced it in an HBV-dominant East Asian population but baseline OS was 4 months shorter — the first revelation of HCC etiology heterogeneity. Over the following decade, BRISK-FL / LiGHT (“challenger TKIs” brivanib / linifanib) both failed, and sora dominated 1L until REFLECT showed non-inferiority in 2018.

SHARP [PMID 18650514] (Llovet 2008 N Engl J Med, N=602): sorafenib 400 mg bid vs placebo in advanced HCC. mOS 10.7 vs 7.9 months (HR 0.69, p<0.001), mTTP 5.5 vs 2.8 months. Caucasian / HCV-dominant. HCC’s first positive phase III systemic therapy — the 3-month absolute OS benefit ended the “no drugs available” era.
Asia-Pacific sorafenib (Oriental) [PMID 19095497] (Cheng 2009 Lancet Oncol, N=271): sorafenib vs placebo in East Asia (China / Korea / Taiwan) HBV ~73% population. mOS 6.5 vs 4.2 months (HR 0.68). HR nearly identical to SHARP but absolute OS 4 months shorter — the first phase III revelation that HBV-HCC has worse baseline prognosis. Population heterogeneity became mandatory consideration for HCC research thereafter.
BRISK-FL [PMID 23980084] (Johnson 2013 J Clin Oncol, N=1155): brivanib (VEGFR2+FGFR TKI) vs sorafenib 1L. Non-inferiority not met (OS HR 1.06, 95% CI 0.93-1.22), brivanib AE worse. Sora’s monopoly further consolidated.
LiGHT (linifanib trial) [PMID 25488963] (Cainap 2015 J Clin Oncol, N=1035): linifanib vs sorafenib 1L. OS HR 1.046, double failure (linifanib more toxic and ineffective). Sora’s 1L position completely unchallenged.

Takeaway: 2008-2017 was a decade with only sorafenib in 1L HCC. mOS ceiling ~11 months (global) / ~6.5 months (HBV-dominant East Asia) — HCC’s “loneliest decade.” But these ten years established three fundamental lessons for HCC research: etiology heterogeneity (HBV vs HCV vs non-viral) → phase III must stratify; Child-Pugh A as enrollment gate universality; “non-inferiority to sora” is far from enough to win — substantial OS improvement is required.

2.2 Multi-TKI 2L breakthrough and 1L non-inferiority (2017-2019): sorafenib’s monopoly pried open

In 2017 RESORCE made regorafenib the first positive 2L regimen in ten years; in 2018 CELESTIAL’s cabozantinib further broadened 2L; in 2019 REACH-2 used AFP ≥ 400 ng/mL enrichment to make ramucirumab HCC’s first biomarker-selected positive phase III; in 2018 REFLECT’s lenvatinib finally achieved non-inferiority to sora in 1L; in 2021 AHELP’s Chinese domestically-developed apatinib (= rivoceranib) showed 2L positivity, paving the way for the CARES-310 1L combination in 2023.

RESORCE [PMID 27932229] (Bruix 2017 Lancet, N=573): regorafenib 160 mg d1-21 q4w vs placebo in sora-tolerant (sora 400 mg/d ≥ 20/28 days) progressed patients. mOS 10.6 vs 7.8 months (HR 0.63, p<0.0001). First positive 2L in a decade — established the “sorafenib continuum of care” concept (2L benefit conditional on prior 1L sora tolerance).
REFLECT [PMID 29433850] (Kudo 2018 Lancet, N=954): lenvatinib vs sorafenib 1L. OS HR 0.92 (95% CI 0.79-1.06, non-inferiority met); mPFS 7.4 vs 3.7 months, ORR 24.1% vs 9.2%. First non-sora TKI in 1L after 10 years. mOS 13.6 vs 12.3 months.
CELESTIAL [PMID 29972759] (Abou-Alfa 2018 N Engl J Med, N=707): cabozantinib (MET/AXL/VEGFR2 TKI) vs placebo at ≤ 2 prior lines. mOS 10.2 vs 8.0 months (HR 0.76, p=0.005). MET/AXL mechanism addresses sora resistance, but G3-4 AE 68% vs 36% — clinically screen for good PS patients.
REACH-2 [PMID 30665869] (Zhu 2019 Lancet Oncol, N=292): ramucirumab vs placebo 2L, only AFP ≥ 400 ng/mL population. mOS 8.5 vs 7.3 months (HR 0.71, p=0.0199). HCC’s first biomarker-selected positive phase III — AFP-high biology driven by VEGFR2 pathway. Clinical threshold: AFP ≥ 400 to give ramu.
AHELP [PMID 33971141] (Qin 2021 Lancet Gastroenterol Hepatol, N=393, China 31 centers): apatinib = rivoceranib (VEGFR2 TKI) vs placebo 2L+, HBV ~82%. mOS 8.7 vs 6.8 months (HR 0.785, p=0.048). Validation of a Chinese domestically-developed VEGFR2 TKI in 2L — the same molecule became the 1L combination backbone of CARES-310 two years later. Classic Chinese pharma pathway: “2L validation → 1L combination.”

Takeaway: 2017-2021 2L landscape = choose among regorafenib (sora-tolerant) + cabozantinib (broad-spectrum) + ramucirumab (AFP≥400) + apatinib (NMPA-exclusive). 1L was pried open by REFLECT — but sora / lenva had similar ~13 months mOS. True 1L rewriting had to wait for IO.

2.3 IO + anti-angiogenic 1L rewriting (2020-2024): the four-way standoff

In 2020 IMbrave150 first sent IO + anti-angiogenic into 1L (atezo+bev vs sora), OS HR 0.58; in 2021 ORIENT-32 (domestic sintilimab + IBI305) reproduced HR 0.57 in an HBV ≥ 93% Chinese cohort; in 2022 HIMALAYA’s STRIDE regimen (single treme priming + durva Q4W) became the first 1L IO regimen without anti-angiogenic; in 2023 CARES-310 (camrelizumab + rivoceranib, China-led 13-country multicenter) pushed mOS to 22.1 months (longest in 1L HCC phase III history); in 2025 CheckMate-9DW’s nivo+ipi pushed further to 23.7 months but with early hazard crossover. Four years, 5 positive 1L phase III trials, HR converging from 0.58 to 0.79 — the IO backbone held up 1L in unstratified populations.

IMbrave150 (primary) [PMID 32402160] (Finn 2020 N Engl J Med, N=501): atezolizumab + bevacizumab (A+B regimen) vs sorafenib 1L. OS HR 0.58 (p<0.001). HCC’s first positive 1L IO combination phase III — 1L SoC switched tracks from this point.
IMbrave150 updated [PMID 34902530] (Cheng 2022 J Hepatol): 12-month follow-up update. mOS 19.2 vs 13.4 months (HR 0.66) — more mature OS data than the primary analysis. Became the cornerstone control for 2L IO trials.
ORIENT-32 [PMID 34143971] (Ren 2021 Lancet Oncol, N=571, China): sintilimab + IBI305 (bev biosimilar) vs sorafenib, HBV ≥ 93%. mOS not reached vs 10.4 months (HR 0.57). NMPA approved, not submitted to FDA, compressed drug cost to about 1/3-1/4 of atezo+bev. A phase III dedicated to HBV-enriched population.
HIMALAYA [PMID 38319892] (Abou-Alfa 2022 NEJM Evid, N=1171): STRIDE regimen = single tremelimumab (CTLA-4 mAb) 300 mg priming + durvalumab (durva, PD-L1 mAb) 1500 mg Q4W vs sorafenib. mOS 16.43 vs 13.77 months (HR 0.78, p=0.0035). Durva monotherapy vs sora non-inferior (HR 0.86). First 1L IO regimen without anti-angiogenic — a lifesaving option for patients with esophageal/gastric varices or bev contraindications. PD-L1 low subgroup benefited numerically more (reverse-biomarker phenomenon).
COSMIC-312 [PMID 35798016] (Kelley 2022 Lancet Oncol, N=837): cabozantinib + atezolizumab vs sorafenib 1L. PFS HR 0.63 (positive) but OS HR 0.90 (p=0.44, negative). Lesson: MET/AXL inhibition may actually weaken IO benefit, TKI backbones are not interchangeable — bev succeeds / cabo fails / lenva borderline (LEAP-002) despite all being TKI+IO.
LEAP-002 [PMID 38039993] (Llovet 2023 Lancet Oncol, N=794): pembrolizumab + lenvatinib vs lenvatinib + placebo. mOS 21.2 vs 19.0 months (p=0.023, did not meet prespecified threshold p ≤ 0.019). Dual primary endpoint failure — exposed that lenva monotherapy in modern control arms has been underestimated; the OS gap between 1L combo and lenva monotherapy narrowed to a borderline ~2 months.
RATIONALE-301 [PMID 37796513] (Qin 2023 JAMA Oncol, N=674): tislelizumab monotherapy vs sorafenib. Non-inferiority met (OS HR 0.85, 95.003% CI 0.71-1.02), mOS 15.9 vs 14.1 months. mDoR 36.1 vs 11.0 months (extremely beautiful long tail). FDA approved 2024. Second 1L IO regimen without anti-angiogenic (besides durva mono).
CARES-310 [PMID 37499670] (Qin 2023 Lancet, N=543, 13-country multicenter, HBV ~77%): camrelizumab + rivoceranib (= apatinib) vs sorafenib 1L. mOS 22.1 vs 15.2 months (HR 0.62, p<0.0001) — longest mOS in 1L HCC phase III history. Simplified regimen of all-oral TKI + biweekly IV IO (vs atezo+bev’s dual IV every 3 weeks). FDA formally approved 2024.
CheckMate-9DW [PMID 40349714] (Yau 2025 Lancet, N=668): nivolumab + ipilimumab (nivo+ipi) vs investigator’s choice lenva/sora 1L. mOS 23.7 vs 20.6 months (HR 0.79, p=0.018). Early hazard crossover — first 6 months HR 1.65 (worse), after that HR 0.61 (improved); 12 TRAE deaths vs 3 — dual IO requires 6-12 month functional reserve.

Takeaway: 2026 1L IO landscape = atezo+bev (IMbrave150 updated mOS 19.2) / STRIDE (HIMALAYA 16.4) / cam+rivo (CARES-310 22.1) / nivo+ipi (9DW 23.7) four-way standoff; domestic sinti+IBI305 (ORIENT-32) provides cost advantage for HBV Chinese cohorts; tislelizumab / durvalumab monotherapy as bev-contraindicated alternatives. But all positive results with HR 0.58-0.79 are in unstratified populations — no IO regimen has PD-L1 / TMB / MSI cut-off as stratification enrollment.

2.4 The “zero biomarker” precision dilemma (2020-2026): HCC’s unique reverse-biomarker phenomenon

HCC’s three main drivers — TERT promoter mutation (~60%), TP53 (~30%), CTNNB1 (~30%, β-catenin pathway) — are all undruggable. Sub-frequency MET amplification and FGF19 amplification have low prevalence (5-10% each) and phase III failed (COSMIC-312 cabo+atezo OS negative [PMID 35798016]). In the IO era, no 1L / 2L HCC trial enrolled by molecular stratification — zero predictive biomarkers approved to date. Even more anomalously, HIMALAYA’s STRIDE benefited numerically more in the PD-L1 low subgroup, suggesting HCC may be a “reverse biomarker” tumor type (PD-L1 ≠ response prediction).

HCC driver gene landscape: TERT promoter mutation 55-60% (undruggable, mechanism differs from coding-region mutations); TP53 30% (undruggable); CTNNB1 25-30% (β-catenin undruggable); total ~90% tumors carry at least one driver but all three are untargetable — this is the most fundamental molecular difference between HCC and NSCLC (EGFR 40% druggable) / BTC (FGFR2 ~15% druggable + IDH1 ~15% druggable).
COSMIC-312 [PMID 35798016] (Kelley 2022 Lancet Oncol): an attempt at MET/AXL as theoretical enhancer target. Cabo+atezo vs sora, PFS positive OS negative — MET overexpression enrollment not stratified. Mechanistic lesson: not all TKI backbones are suitable as IO partners, cabo/atezo failure suggests MET/AXL inhibition may weaken IO benefit.
LEAP-002 [PMID 38039993] (Llovet 2023 Lancet Oncol): pembro+lenva vs lenva. Not stratified by PD-L1 or VEGF pathway activity, dual primary endpoint failure.
HIMALAYA [PMID 38319892] (Abou-Alfa 2022 NEJM Evid) “reverse biomarker” phenomenon: subgroup analysis showed PD-L1 low-expression subgroup benefited more numerically from STRIDE, PD-L1 high-expression subgroup HR approached 1.0. Contrary to the biological logic of NSCLC / BTC (high PD-L1 responders). Not used as a stratification biomarker.
Soft constraints from etiology stratification: CheckMate-459 [PMID 34914889] and IMbrave150 subgroups suggest NASH / MASH-HCC may respond to IO worse than HBV/HCV-driven HCC. Mechanistic hypothesis (Pfister Nature 2021): CD8+PD-1+ T cell exhaustion patterns in NASH differ — but all phase IIIs only did descriptive subgroups, no head-to-head evidence.
AFP as pharmacodynamic biomarker rather than predictive biomarker: HCC has AFP dynamic monitoring as an early response indicator (ALBI / AFP change predicts PFS), but not a treatment selection biomarker — only REACH-2 (ramucirumab) uses AFP ≥ 400 as enrollment gate.

Takeaway: in 2026 the clinical utility of HCC molecular testing = extremely limited. NCCN V1.2026 still recommends testing HBV/HCV DNA + AFP + BCLC staging rather than a gene panel. The “biomarkers” that actually change clinical decisions are Child-Pugh (liver function) + AFP + etiology + tumor burden + ECOG PS — all clinical parameters. This contrasts with NSCLC’s mandatory EGFR/ALK/ROS1/KRAS/PD-L1 panel and BTC’s mandatory FGFR2/IDH1/HER2/MSI panel. The “zero biomarker dilemma” is HCC’s most urgent research agenda for 2026 (see §4 gaps 1-3).

2.5 Perioperative / adjuvant + TACE integration (2015-2026): early-readout reversal + intermediate BCLC-B paradigm shift

In 2015 STORM’s negative adjuvant sorafenib closed the door on TKI adjuvant, and HCC adjuvant remained blank for years; in 2022-2023 two single-center neoadjuvant IO phase II trials (Marron cemiplimab / Kaseb MDACC nivo±ipi) gave signals of 20% pathologic necrosis; in 2023 IMbrave050 (Qin Shukui PI), as HCC’s first adjuvant phase III, achieved positive RFS HR 0.72 — reversed in 2026 long-term follow-up, with RFS HR converging to 0.90 and OS HR 1.26 trending unfavorable; Roche withdrew the adjuvant indication in 2024. For intermediate BCLC-B, SPACE 2016 (DEB-TACE + sora) negative ended the first TKI+TACE wave; LAUNCH 2023 (lenva+TACE) China phase III positive; LEAP-012 (pembro+lenva+TACE) and EMERALD-1 (durva+bev+TACE) global phase III trials successively positive on PFS in 2024-2025 but OS still pending — intermediate HCC is turning the page from “TACE alone.”

STORM [PMID 26361969] (Bruix 2015 Lancet Oncol, N=1114): adjuvant sorafenib after curative resection vs placebo. mRFS 33.3 vs 33.7 months (HR 0.940, p=0.26, negative); G3-4 hand-foot skin reaction 28% vs <1%. Killed adjuvant TKI, HCC adjuvant treatment remained blank for years.
Marron neoadjuvant cemiplimab [PMID 35065058] (Marron 2022 Lancet Gastroenterol Hepatol, N=20): neoadjuvant cemiplimab (PD-1 monotherapy) phase II. 4/20 (20%) achieved > 70% pathologic necrosis. First published neoadjuvant IO monotherapy phase II.
Kaseb MDACC perioperative nivo±ipi [PMID 35065057] (Kaseb 2022 Lancet Gastroenterol Hepatol, N=27 RCT phase II): nivo mono ORR 23% vs nivo+ipi 0% (RECIST); MPR 23% vs 21%; G3-4 AE 23% vs 43%. Monotherapy not inferior to combination + lower toxicity.
IMbrave050 (primary) [PMID 37871608] (Qin 2023 Lancet, N=668): Qin Shukui PI, 12-month adjuvant atezo+bev after curative resection in high-risk patients vs active surveillance. RFS HR 0.72 (95% CI 0.53-0.98, p=0.012), positive at interim. HCC’s first positive adjuvant phase III, Grade 3-4 AE 41% vs 13%.
IMbrave050 updated [PMID 41580093] (Yopp 2026 J Hepatol): long-term follow-up reversed. RFS HR 0.90 (95% CI 0.72-1.12) benefit not sustained; OS HR 1.26 (95% CI 0.85-1.87) trending unfavorable. Roche withdrew the HCC adjuvant indication in 2024. Textbook-level “early readout ≠ final conclusion” case — HCC is a hot zone for OS reversals.
Kaseb biomarker analysis [PMID 39427654] (LaPelusa 2025 Oncology, N=18 translational): MPR responders showed post-treatment intratumoral CD8 +26.9%, granzyme B +15.6%, PD-1 +20.2%. Baseline tumor size + dynamic immune infiltration as candidate biomarkers — still research stage.
SPACE [PMID 26809111] (Lencioni 2016 J Hepatol, N=307): DEB-TACE + sora vs DEB-TACE + placebo in BCLC-B intermediate. mTTP 169 vs 166 days (HR 0.80, p=0.072, NS). Ended the first TKI+TACE wave — plain TKI addition provides no help to TACE.
LAUNCH [PMID 35921605] (Peng 2023 J Clin Oncol, N=338, China 12 centers): lenva + TACE vs lenva monotherapy, mostly BCLC-C / MVI (macrovascular invasion). mOS 17.8 vs 11.5 months (HR 0.45, p<0.001), mPFS 10.6 vs 6.4 months, ORR 54% vs 25%. Pre-IO-era TKI+TACE proof of concept — China 12-center led.
LEAP-012 [PMID 39798578] (Kudo 2025 Lancet, N=480, global): pembro + lenva + TACE vs TACE + dual placebo, Asian enrollment 72%. mPFS 14.6 vs 10.0 months (HR 0.66, p=0.0002); 24-month OS 75% vs 69% (HR 0.80, first OS interim did not reach significance). First positive IO+TKI+TACE phase III in intermediate HCC.
EMERALD-1 [PMID 39798579] (Sangro 2025 Lancet, N=616, global three-arm): durva + bev + TACE vs durva + TACE vs placebo + TACE. Triplet vs placebo mPFS 15.0 vs 8.2 months (HR 0.77, p=0.032); durva monotherapy + TACE not superior to placebo — mechanistic lesson: IO + anti-angiogenic combination is required, IO alone is not enough. OS still pending.

Takeaway: in 2026 HCC perioperative / adjuvant has no approved SoC (IMbrave050 withdrawal is the only such status among GI tumor types). Intermediate BCLC-B is turning from “TACE alone” to pembro+lenva+TACE (LEAP-012) or durva+bev+TACE (EMERALD-1), but the two flagships’ mature OS is still in follow-up — the IMbrave050 reversal cautionary tale tells us: do not write “practice-changing” before mature OS comes out.

3. Lateral: 2026 current decision landscape (six dimensions)

Projecting the longitudinal evolution onto concrete 2026 clinical decision trees, below are six key branchpoints and the evidence basis for each.

3.1 Child-Pugh A + BCLC-C advanced 1L: how to choose among the four-way standoff

2026 mainstream: four positive 1L IO combinations stand in parallel; choice is determined by bev accessibility + patient functional reserve + availability + cost.

Subgroup	First choice	Alternative
bev available (no severe EV, no active bleeding)	atezo+bev [IMbrave150 PMID 32402160 / updated PMID 34902530] (mOS 19.2 months, HR 0.66) or cam+rivo [CARES-310 PMID 37499670] (mOS 22.1 months, HR 0.62, all-oral TKI simplified regimen)	ORIENT-32 (HBV Chinese cohort, cost advantage)
bev contraindicated (EV bleeding / active GI bleeding / recent major surgery)	STRIDE durva+treme (HIMALAYA [PMID 38319892], mOS 16.43 months, HR 0.78, no anti-angiogenic)	tislelizumab mono (RATIONALE-301 [PMID 37796513], OS non-inferior HR 0.85)
Good functional reserve + 6-12 month life expectancy	nivo+ipi (CheckMate-9DW [PMID 40349714], mOS 23.7 months) — note the first 6 months HR 1.65 worsening risk	atezo+bev / cam+rivo
Borderline Child-Pugh B7 / rapid progression	Avoid dual IO and dual TKI+IO combinations	lenva monotherapy (REFLECT [PMID 29433850]) or BSC

Controversies: atezo+bev vs cam+rivo vs nivo+ipi have no head-to-head phase III. Cross-trial comparison shows CARES-310 mOS 22.1 is highest, but the control arm was sora (sora monotherapy is no longer mainstream in 2023); 9DW mOS 23.7 is higher but with dual-IO early mortality risk; atezo+bev is most mature (5-year real-world data). Choice is mainly determined by accessibility / reimbursement / prior bleeding history, not efficacy difference — because in the narrow HR 0.58-0.79 band there is no cross-trial distinguishing power.

NCCN V1.2026 Hepatobiliary: atezo+bev / STRIDE / nivo+ipi / cam+rivo are all Category 1 preferred; tislelizumab mono / durvalumab mono are Category 1 (bev-contraindicated alternatives).

3.2 Child-Pugh B / borderline liver function: can IO be used?

2026 mainstream: all 1L IO phase IIIs enrolled only Child-Pugh A. Evidence for Child-Pugh B patient IO = subgroup extrapolation + single-arm phase II + real-world retrospective.

CheckMate-040 Child-Pugh B expansion cohort (El-Khoueiry 2017 [PMID 28434648] original cohort was CP-A): subgroup analysis suggests nivo in CP-B has ORR ~12% (lower than CP-A 20%), mOS ~7.4 months. No phase III.
Real-world data: multinational retrospective shows CP-B atezo+bev mOS approximately 6-9 months vs CP-A 19 months, but bev-related bleeding risk is higher.
2026 clinical decisions: Child-Pugh B7-8 may try IO monotherapy (tislelizumab or durvalumab, avoiding bev + avoiding ipi); B9+ does not recommend any 1L IO, switch to BSC or lenva monotherapy (REFLECT CP-A evidence cannot be extrapolated).
Controversies: STORM trial [PMID 26361969] subgroup suggests sora in CP-B has far higher toxicity — TKI is equally unsafe in patients with poor liver function. Systemic therapy for Child-Pugh B remains a research gap in 2026 (see §4 gap 4).

3.3 Etiology stratification: HBV vs HCV vs non-viral (MASH) response to IO

2026 mainstream: etiology subgroups across the 4 1L IO phase III trials suggest differences in IO response profiles.

HBV-HCC (East Asia-dominant, > 80% of Chinese HCC): CARES-310, ORIENT-32, CheckMate-459 subgroup HRs are all most favorable (0.5-0.6 range). HBV mechanistic hypothesis: chronic viral-driven T cell infiltration + high baseline PD-1 expression; IO more effective at releasing exhaustion. HBV-HCC first choice is cam+rivo or sinti+IBI305 (cost advantage).
HCV-HCC (Europe/US / Japan-dominant): SHARP original population + IMbrave150 subgroup HR ~0.65-0.70. First choice atezo+bev or STRIDE.
Non-viral / MASH-HCC (rising year-over-year in Europe/US): CheckMate-459 [PMID 34914889] nivo vs sora subgroup HR approaches 1.0; IMbrave150 subgroup HR numerically slightly worse than HCV. Mechanistic hypothesis (Pfister Nature 2021 mechanistic study): in NASH-driven HCC, CD8+PD-1+ T cells are in auto-aggressive exhaustion mode, and IO may actually aggravate hepatic parenchymal damage — this is the biological explanation for “IO underperforms in MASH-HCC”.
2026 clinical decisions: IO selection for MASH population has the weakest evidence; avoid dual IO (nivo+ipi); prefer TKI+IO (atezo+bev / cam+rivo), with TKI monotherapy (lenva) if necessary. Phase III systemic evidence for non-viral HCC remains notably insufficient in 2026 — Western registry cohorts are accumulating.

3.4 Intermediate BCLC-B locoregional + IO integration: sequencing of TACE + IO combinations

2026 mainstream: LEAP-012 / EMERALD-1 two phase IIIs positive on PFS but mature OS still pending → don’t rush to rewrite as universal SoC before mature OS.

Subgroup	Regimen	Evidence
BCLC-B locoregional-dominant, good liver function	pembro + lenva + TACE [LEAP-012 PMID 39798578] (mPFS 14.6 months, HR 0.66) or durva + bev + TACE [EMERALD-1 PMID 39798579] (mPFS 15.0 months, HR 0.77)	phase III PFS positive, OS pending
MVI / locoregional-systemic compound risk	lenva + TACE [LAUNCH PMID 35921605] (mOS 17.8 months, HR 0.45)	Chinese phase III, covers MVI subgroup
EMERALD-1 lesson	durva monotherapy + TACE not superior to placebo + TACE	mechanism: IO + anti-angiogenic combination is required

Controversies: before mature OS, LEAP-012 / EMERALD-1 cannot fully replace traditional TACE. In 2026 clinical practice, combination regimens are commonly tried in high tumor burden / beyond-TACE-indication borderline / downstaging-intent patients; typical intermediate lesions still prioritize TACE. The double historical lesson of “IMbrave050 reversal + SPACE negative” makes the HCC field especially cautious about new intermediate-stage phase III results.

3.5 Adjuvant / perioperative: the void after IMbrave050 withdrawal

2026 mainstream: HCC has no approved adjuvant SoC — the only such status among GI tumor types.

Post-curative-resection high-risk patients (MVI / multifocal / > 5 cm / positive margins): atezo+bev adjuvant was used in 2023 [IMbrave050 primary PMID 37871608], Roche withdrew the indication in 2024 (based on updated PMID 41580093 RFS HR 0.90 + OS HR 1.26 reversal). 2026 standard = active surveillance.
Neoadjuvant IO monotherapy: Marron cemiplimab [PMID 35065058] 4/20 pathologic necrosis + Kaseb MDACC [PMID 35065057] nivo mono MPR 23% are early signals — none are SoC, only for eligible clinical trial enrollment.
Ongoing phase III adjuvant trials: EMERALD-2 (durva ± bev adjuvant), CheckMate-9DX (nivo adjuvant), KEYNOTE-937 (pembro adjuvant) — OS readout expected 2027-2029.
2026 clinical decisions: after curative resection do not routinely recommend adjuvant IO / adjuvant TKI (two negative lessons of STORM [PMID 26361969] + IMbrave050 updated); do not rewrite before EMERALD-2 / 9DX / KN-937 mature OS.

3.6 2L+ sequencing: the off-label dilemma in the post-IO era

2026 mainstream: RESORCE / CELESTIAL / REACH-2 / AHELP all tested in sora-progressor population; after 1L switched from sora to IO+anti-angiogenic, post-IO 2L has no positive phase III.

Scenario	Regimen	Evidence level
1L sora progression (historical cohort)	regorafenib (RESORCE [PMID 27932229], mOS 10.6 months, HR 0.63, requires sora-tolerant)	Category 1
1L sora progression + AFP ≥ 400	ramucirumab (REACH-2 [PMID 30665869], mOS 8.5 months, HR 0.71)	Category 1
1L sora progression + broad-spectrum coverage needed	cabozantinib (CELESTIAL [PMID 29972759], mOS 10.2 months, HR 0.76)	Category 1 (G3-4 AE 68%, screen PS)
1L IO+anti-angiogenic progression (2026 mainstream)	off-label lenva / cabo / regorafenib / rivoceranib (AHELP [PMID 33971141])	expert consensus, no phase III
KEYNOTE-394 Asian 2L pembro	post-sora pembro Asian confirmatory (mOS 14.6 months, HR 0.79)	regional confirmatory case for FDA-retained accelerated approval

Controversies: post-IO 2L in 2026 is HCC’s most urgent unmet need. ivonescimab (AK112, PD-1+VEGF bispecific) HCC phase II signals / cadonilimab (AK104, PD-1+CTLA-4 bispecific) COMPASSION-08 phase II data are already available, phase III readout window 2026-2027. Before then all clinical decisions rely on ESMO/NCCN expert consensus off-label.

4. Research Gaps: ten unsolved clinical problems

This report identifies the following gaps, all definable concrete problems (not the cliché “more research is needed”):

HCC has zero approved predictive biomarkers — mechanistic explanation missing: TERT / TP53 / CTNNB1 three main drivers all undruggable; PD-L1 / TMB / MSI failed to predict response in all 1L IO phase IIIs. The molecular mechanism of HCC’s uniqueness (promoter-mutation-dominant + immune cold + special intrahepatic microenvironment) needs systematic correlative science.
Is PD-L1 a “reverse biomarker” in HCC?: HIMALAYA STRIDE’s PD-L1 low subgroup benefited numerically more — contrary to the biological logic of high-PD-L1 response in NSCLC / BTC / gastric cancer. Prospective PD-L1 stratified design is needed for confirmation.
No head-to-head phase III among HCC IO combinations: atezo+bev / STRIDE / cam+rivo / nivo+ipi four 1L phase III trials fall within the narrow HR 0.58-0.79 band for cross-trial comparison. Clinical decisions rely on accessibility / toxicity profile / cost, not efficacy evidence — selection dilemma.
Prospective IO safety data for Child-Pugh B is missing: all 1L IO phase IIIs enrolled only CP-A. IO choice for CP-B7-9 = subgroup extrapolation + phase II + real-world retrospective — dedicated phase III needed.
Differential IO response in MASH / non-viral HCC: CheckMate-459 / IMbrave150 subgroups suggest weaker IO response in MASH-HCC (HR ~1.0); Pfister Nature 2021 mechanistic study provides the hypothesis but it has not been prospectively validated. Western registry cohort MASH proportion is rising → MASH-only RCT needed.
Mature OS and sequencing of TACE + IO combinations: LEAP-012 / EMERALD-1 PFS positive but OS still pending. The double historical lesson of SPACE (TACE+sora negative) + IMbrave050 updated (adjuvant reversal) — cannot rewrite as universal SoC before mature OS.
IMbrave050 adjuvant OS has not been positive to date: HCC is the only GI tumor type with no approved adjuvant SoC. EMERALD-2 / CheckMate-9DX / KEYNOTE-937 readouts 2027-2029 — if they continue negative, HCC adjuvant path needs to be rethought.
Complete absence of post-IO 2L phase III: RESORCE / CELESTIAL / REACH-2 all done in sora-progressors; 2L choice after 1L IO+anti-angiogenic is HCC’s most urgent research gap in 2026. ivonescimab / cadonilimab phase III are candidate breakthroughs.
Standardization of downstaging → surgery + AFP dynamic evaluation: Chinese multicenters are performing secondary surgery / transplantation after IO+TKI downstaging, but RCT evidence is insufficient; AFP dynamic change as treatment evaluation aid has correlative data but has not been formalized into a decision tool.
Value of next-generation IO (LAG-3 / TIGIT) + ctDNA-guided treatment decisions in HCC: NSCLC / melanoma already have LAG-3 / TIGIT phase III readouts; HCC has no large-scale phase III in 2026. ctDNA-guided adjuvant de-escalation has launched in other tumor types; HCC has not entered.

5. 2024-2026 latest developments

5.1 FDA / NMPA new approvals (HCC-relevant excerpts)

Drug	Agency	Date	Indication / supporting trial
atezolizumab + bevacizumab	FDA	2020-05-29	1L advanced HCC / IMbrave150 [PMID 32402160]
sintilimab + IBI305	NMPA	2021	1L advanced HCC (HBV-enriched) / ORIENT-32 [PMID 34143971]
durvalumab + tremelimumab STRIDE	FDA	2022-10-21	1L advanced HCC / HIMALAYA [PMID 38319892]
camrelizumab + rivoceranib	NMPA	2023; FDA	1L advanced HCC / CARES-310 [PMID 37499670]
tislelizumab mono	FDA	2024-03-13	1L advanced HCC (OS non-inferior to sora) / RATIONALE-301 [PMID 37796513]
nivolumab + ipilimumab (1L)	FDA	2025-04	1L advanced HCC / CheckMate-9DW [PMID 40349714]
atezolizumab + bevacizumab adjuvant indication	FDA / Roche	withdrawn 2024	based on IMbrave050 updated [PMID 41580093] RFS HR 0.90 + OS HR 1.26

Key observation: 2024-2025 was the “second approval wave” for HCC 1L IO — tislelizumab mono and nivo+ipi received 2 FDA approvals within 2 years; in the same period the withdrawal of the IMbrave050 adjuvant indication became the most educational event in HCC in 2024.

5.2 Key conference readouts (2024-2026, de-weighted notation)

The following entries are candidate pool only before formal peer review and do not enter the main database.

IMbrave050 updated OS [PMID 41580093] (Yopp 2026 J Hepatol): RFS HR 0.90 + OS HR 1.26 reversal. The most educational long-term follow-up event in HCC 2024-2026.
CheckMate-9DW mature OS (ASCO 2025 / ESMO 2025): mOS 23.7 months stable ([PMID 40349714] data); early hazard crossover still visible.
LEAP-012 OS first interim (ASCO GI 2025 [PMID 39798578]): 24-month OS 75% vs 69% (HR 0.80, did not reach significance, OS readouts limited by α spending).
EMERALD-1 first OS interim (ASCO GI 2025 [PMID 39798579]): triplet OS curves separated but did not reach the prespecified significance threshold.
ivonescimab (AK112, Akeso PD-1+VEGF bispecific) HCC phase II (2024-2025 conference data, full publication pending): RM HCC 2L signal, phase III HARMONi-6 ongoing.
cadonilimab (AK104, Akeso PD-1+CTLA-4 bispecific) COMPASSION-08 [PMID 37942328 not in hcc.yaml main database, as hypothesis-generating]: cadonilimab + lenva signal in HCC 1L.

5.3 Ongoing phase III (2025-2028 readout selection)

EMERALD-2 (NCT03847428): durva ± bev adjuvant vs placebo adjuvant after curative resection HCC — OS readout 2027-2028
CheckMate-9DX (NCT03383458): nivo adjuvant vs placebo after curative resection HCC — OS 2027-2028
KEYNOTE-937 (NCT03867084): pembro adjuvant vs placebo after curative resection HCC — OS 2027-2028
LEAP-012 mature OS + EMERALD-1 mature OS: whether intermediate BCLC-B IO+TKI+TACE can be rewritten as SoC depends on these two OS readouts in 2026-2027
HARMONi-6 (Akeso AK112 ivonescimab in HCC): phase III ongoing, readout window 2026-2028
post-IO 2L phase III: still no positive regimen in 2026; candidates include ivonescimab monotherapy / cadonilimab+lenva / next-generation TKIs

6. Convergent insights and judgments

6.1 Longitudinal × lateral: the 2026 HCC landscape shaped by three “resonances”

Overlaying the longitudinal paradigm evolution on the lateral current decision landscape, the 2026 HCC landscape is a superposition of three resonances:

The unique evolution “sorafenib solo for 10 years (2008-2017) → 4 IO combinations as 1L SoC (2020-2024) → zero biomarker dilemma (to date)”: HCC’s 1L mOS was pushed from 10.7 months to 22-24 months (CARES-310 22.1, 9DW 23.7) over 17 years, driven by the IO backbone rather than molecular stratification. Compared to NSCLC’s EGFR/ALK/ROS1/KRAS/MET/HER2/RET/BRAF/NTRK/PD-L1 dozens of molecular stratification paths + parallel IO, and BTC’s 9 approved biomarkers in FGFR2/IDH1/HER2/BRAF/NTRK/RET/MSI/TMB/claudin18.2 — HCC walked its own path of “no molecular stratification, with IO combinations + clinical parameters (Child-Pugh/AFP/etiology) holding up the entire field.” The ceiling of this path is evident: four IO regimens cluster in the narrow HR 0.58-0.79 band, further breakthroughs require mechanistic innovation, not adding another of the same class.
The HCC-specific “Chinese data leads globally”: among 42 landmark trials, CARES-310 (China-led 13-country), ORIENT-32 (all-China), LAUNCH (all-China), SoraHAIC (all-China), FOHAIC-1 (all-China), AHELP (all-China), Chen 2006 (Sun Yat-sen University), Huang 2010 (West China), IMbrave050 (Qin Shukui PI) were all led by Chinese / Asia-Pacific PIs — making HCC one of the tumor types with the strongest Chinese data contribution in medical oncology. Root cause: > 50% of new HCC cases globally are in Asia-Pacific + China’s high HBV prevalence — clinical research is necessarily China-led. Comes with dividends (detailed East Asian population data + optimal HBV subgroup HR + domestic IO cost advantage) and challenges (scarce MASH-HCC evidence + weaker Western applicability).
“Early-readout reversal” is especially frequent in HCC: IMbrave050 primary [PMID 37871608] RFS HR 0.72 positive → updated [PMID 41580093] RFS HR 0.90 + OS HR 1.26 reversal + Roche indication withdrawal — one of the most educational long-term follow-up events in oncology in 2024. The three histories of SPACE (2016 TKI+TACE negative) + LEAP-002 (2023 borderline miss) + IMbrave050 (2024 reversal) tell us: HCC is a hot zone for OS reversals, writing “practice-changing” before mature OS often backfires. In 2026 we should be especially cautious about mature OS from LEAP-012 / EMERALD-1.

These three resonances together explain a clinical phenomenon: the 1L decision for a newly diagnosed stage IV HCC patient in 2026 has 1-2 more decision layers than in 2016 (bev accessibility / functional reserve / etiology), but the decision tree itself is “narrow in width + shallow in depth” — four IO combinations cluster in the narrow HR band, no molecular panel needed. This differs completely from NSCLC’s multi-layer decision tree (driver panel → PD-L1 → combo) and BTC’s four biomarker-panel paths (FGFR / IDH / HER2 / MSI). HCC decision tree’s “narrow and shallow” feature is the clinical manifestation of the “zero biomarker dilemma.”

6.2 Clinical decision takeaways (for junior-mid oncologists)

1L decisions look at 3 clinical parameters, not a molecular panel: can bev be used? (yes → atezo+bev or cam+rivo; no → STRIDE or tisle/durva mono) + 6-12 month functional reserve? (yes → nivo+ipi an option; borderline → avoid dual IO) + economic accessibility? (HBV Chinese patients → ORIENT-32 cost 1/3-1/4). PD-L1 / TMB / MSI almost never need testing — zero predictive biomarkers approved.
Child-Pugh is the core gate for HCC treatment decisions: all 1L IO phase IIIs enrolled only CP-A. CP-B7-9 may try IO monotherapy (tislelizumab / durvalumab, avoiding bev + ipi); CP-B9+ or CP-C switch to BSC. Do not extrapolate CP-A data to CP-B/C.
Evidence for IO effect in MASH / non-viral HCC is weak: CheckMate-459 subgroup HR approaches 1.0. MASH population first choice TKI+IO (atezo+bev / cam+rivo), avoid dual IO; lenva monotherapy if necessary. Western registry cohort MASH proportion rising → continue to watch for MASH-only RCTs after 2026.
Adjuvant therapy has no SoC in 2026 — active surveillance is the standard: after IMbrave050 withdrawal, HCC is the only GI tumor type with no approved adjuvant regimen. Lessons from STORM (sora adjuvant negative) + IMbrave050 updated (IO adjuvant reversal): do not rewrite before mature OS. Do not give adjuvant off-trial before EMERALD-2 / 9DX / KN-937 readouts.
Don’t rush to fully accept IO+TACE combinations for intermediate BCLC-B: LEAP-012 / EMERALD-1 PFS positive but OS pending; SPACE / IMbrave050 history reminds us that HCC is a reversal hot zone. Typical intermediate lesions still prioritize TACE; try combinations when tumor burden is high / downstaging intent / clinical trial enrollment is possible.
Post-IO 2L has no phase III — off-label relies on expert consensus: after 1L IO+anti-angiogenic progression, lenva / cabo / regorafenib / rivoceranib are all off-label; prioritize clinical trial enrollment (ivonescimab / cadonilimab phase III).
Remember ramucirumab (REACH-2) for AFP ≥ 400 ng/mL + 2L: HCC’s only biomarker-selected positive phase III, easily overlooked in post-IO scenarios.
Sora-progressor is still an evidence-based scenario (but increasingly rare): RESORCE (regorafenib, requires sora-tolerant) remains Category 1; older patients from the 1L sora era can be considered for 2L. In the post-IO era, the mainstream path is 1L IO+anti-angiogenic → 2L off-label.
The first-6-months hazard crossover in CheckMate-9DW is an important clinical cue: nivo+ipi has the highest mOS (23.7 months) but first-6-month HR 1.65 + 12 TRAE deaths vs 3. Borderline Child-Pugh / rapid progression / elderly patients should not choose dual IO — similar selection logic to NSCLC CheckMate-227 / 9LA.
Do not memorize PD-L1 thresholds / TMB cut-offs for HCC decisions: HCC is the only “reverse biomarker” major tumor type (HIMALAYA PD-L1 low subgroup benefited numerically more). In 2026 clinical practice, HCC molecular panel testing is done only in rare research / trial enrollment scenarios. Core stratification is always Child-Pugh × AFP × etiology × BCLC × ECOG × bev accessibility.

Closing

HCC completed a unique arc in oncology over the past 18 years — from SHARP sorafenib in 2008 ending the “no drugs for HCC” era, a decade of sorafenib solo dominance; to 2017-2019 REFLECT / RESORCE / CELESTIAL / REACH-2 / AHELP breaking through 1L non-inferiority + 2L three-way; to 2020-2024 IMbrave150 / HIMALAYA / CARES-310 / CheckMate-9DW four IO combinations pushing 1L mOS to 22-24 months (four-way standoff takes shape); to 2023-2026 the textbook lesson of IMbrave050 adjuvant going from positive to reversed + LEAP-012 / EMERALD-1 as intermediate BCLC-B’s first IO+TACE positives but with mature OS still pending.

HCC’s most fundamental difference from other major tumor types (NSCLC / BTC / PDAC) is not treatment complexity but the unique dilemma of “zero approved predictive biomarkers”. NSCLC has 10+ biomarkers for stratification, BTC has 9 biomarkers matching targets, PDAC just pried open three subtypes KRAS G12C/G12D/pan-KRAS — HCC’s three main drivers TERT/TP53/CTNNB1 remain fully undruggable, and none of PD-L1/TMB/MSI predicts IO response. Clinical stratification forever relies on Child-Pugh × AFP × etiology × BCLC × tumor burden. This path of “holding up the entire field with the IO backbone in unstratified populations + deciding by clinical parameters rather than molecular panels” is HCC’s unique contribution to oncology, but also the bottleneck most needing breakthrough in 2026.

Perioperative IMbrave050 reversal + intermediate LEAP-012 / EMERALD-1 OS pending + post-IO 2L complete absence of phase III — these three areas are HCC’s most densely packed research gaps in 2026. The next decade needs to solve the three structural problems: “can we find HCC’s first predictive biomarker”, “can we push adjuvant IO from RFS positive to OS positive”, and “can we push post-IO 2L from expert consensus to phase III evidence”.

The value of this report is not in “exhaustively listing all trials” (PubMed can do that), but in compressing 18 years of evolution + current decisions + unsolved gaps into the cognitive bandwidth of a single read. Next time you face a newly diagnosed HCC patient, every branch in the decision tree has this map to reference, trace, and query.
