PRIME-HCC: phase Ib study of neoadjuvant ipilimumab and nivolumab prior to liver resection for hepatocellular carcinoma
BMC Cancer volume 21, Article number: 301 (2021)
After liver resection (LR), patients with hepatocellular cancer (HCC) are at high risk of recurrence. There are no approved anti-cancer therapies known to affect such risk, highlighting the acute need for novel systemic therapies to control the probability of disease relapse. Immunotherapy is expanding as a novel treatment option for HCC. Emerging data from cohort 4 of the CA209–040 study, which investigated the safety and preliminary efficacy of nivolumab/ipilimumab co-administration in advanced HCC, suggest that the combination can be delivered safely with an acceptable proportion of reversible grade 3–4 toxicities (27.1%) and a low discontinuation rate (2%) in patients with HCC. Here, we describe the design and rationale of PRIME-HCC, a two-part, multi-centre, phase Ib study to assess safety and bioactivity of the nivolumab/ipilimumab combination prior to LR in early-stage HCC.
The study involves an initial safety run-in phase (Part 1) to allow for preliminary safety characterisation within the first 6 patients enrolled and a subsequent expansion (Part 2). Ipilimumab will be administered once only on Day 1. Nivolumab will be administered on Day 1 and Day 22 (± 3 days) for a total of two 21-day cycles (i.e. 6 weeks of treatment). The primary objective of the study is to determine the safety and tolerability of the nivolumab/ipilimumab combination prior to LR. The secondary objective is to preliminarily characterize the efficacy of the combination prior to LR, including objective response rate (ORR) and pathologic response rates. Additional exploratory objectives include preliminary evidence of long-term disease control and to identify predictive correlates of response to the nivolumab/ipilimumab combination in HCC.
The results of this study will help define the positioning of neoadjuvant nivolumab/ipilimumab combination in the perioperative management of HCC, with potential to improve survival outcomes in this patient population.
Hepatocellular carcinoma (HCC) is the sixth commonest and third most lethal solid malignancy on a global scale . In spite of the major diagnostic advancements, only one out of three of the newly diagnosed patients are eligible for radical treatments upfront . In patients within the Barcelona Clinic Liver Cancer (BCLC) stage 0 or A criteria, surgical resection can be carried out safely with curative intent . However, this is only feasible in < 30% of the patients, mainly due to the extent of radiological spread of the disease or poor synthetic function due to underlying cirrhosis.
The evolving landscape of systemic therapy for HCC
Anti-tumour immunotherapy with monoclonal antibodies blocking the programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) pathways are gaining momentum, where immune checkpoint inhibitors directed against these targets either alone or in combination have shown efficacy in HCC. Pembrolizumab has shown initial evidence of disease-modulating activity in a little less than 20% of patients enrolled in Keynote-224 , but failed to improve OS in Keynote-240, a placebo-controlled phase III trial which investigated pembrolizumab in treatment-experienced patients with advanced HCC . CheckMate-040 (CA209–040) is the reference, open label, multi-cohort, phase I/II study which evaluated safety and efficacy of nivolumab in advanced HCC patients . Despite evidence of anti-tumour activity, the subsequent phase III study CheckMate-459 failed to confirm thedif significant superiority of first-line nivolumab over sorafenib with respect of OS in the advanced disease (HR = 0.85, 95% CI: 0.72–1.02; p = 0.0752) .
Whilst not yet supported by evidence of OS improvement, dual CTLA-4/PD-1 blockade might also be beneficial, given the different and alternative role of the two biologic axes within the cancer immunity cycle, as CTLA-4 is a key driver in downregulation of tumour-antigen presenting cells and in T-regs enhancement, whereas PD-1/PD-L1 mainly impairs the efficiency of the CD8 + CTL response. Reliable evidence of synergistic effects from CTLA-4/PD-1 co-inhibition has been observed in clinical trials amongst other tumour types, in melanoma , renal cell carcinoma  and NSCLC .
In HCC, safety and preliminary efficacy of 3 alternative schedules of nivolumab and ipilimumab have been investigated within the cohort 4 of Checkmate-040. Pre-treated patients with Child-Pugh class A advanced disease have been randomised to receive either nivolumab 3 mg/kg + ipilimumab 1 mg/kg or nivolumab 1 mg/kg + ipilimumab 3 mg/kg or every 3 weeks for four doses followed by maintenance nivolumab monotherapy (240 mg flat dose biweekly) until disease progression or unacceptable toxicity. The further arm evaluated nivolumab 3 mg/kg + ipilimumab 1 mg/kg every 6 weeks until unacceptable toxicity or disease progression. The incidence of treatment related adverse events (TRAEs) for the whole cohort was 37% with a 5% discontinuation rate. The efficacy analysis showed the nivolumab/ipilimumab combination to achieve an ORR of 31%, which was higher than the ORR (14%) reported with single agent nivolumab in the same study, and led to US Food and Drug Administration approval of the nivolumab/ipilimumab combination in treatment-experienced advanced HCC patients .
The rapidly changing landscape of systemic therapy in HCC, where combination immunotherapy has led to reproducible evidence of disease-modulation, has prompted clinicians to consider the expansion of immunotherapy to the earlier stages of the disease. There is an acute need for highly active systemic anti-cancer treatments as a pre-operative strategy to attempt disease down-staging and expand the proportion of patients who might benefit from curative surgery. Furthermore, despite optimal local control of the disease, the majority of patients recur within 2 years of surgery as a likely result of proliferation of microscopic neoplastic foci within the residual organ, and the 5-year survival rate for early-stage HCC ranges between 17 to 53%, with a recurrence rat that can reach 70% also in the curative resection setting [2, 12]. The negative impact on survival secondary to both early and late recurrence of HCC suggests the need for an optimal integration of systemic anti-cancer therapies to control the risk of relapse and increase the chances of cure in patients with early stage HCC.
Currently, there is no standard of care for adjuvant/neoadjuvant treatment and although a number of approaches have been attempted including trans-arterial chemoembolization (TACE), Yttrium-90 radioembolization, and neoadjuvant sorafenib in HCC patients on waiting list for liver transplantation [13,14,15]. Failure to control micro-metastatic disease is a major determinant influencing early relapse and mortality following curative resection and randomized controlled trials have shown sorafenib, to be ineffective in improving outcomes in the adjuvant setting .
Here, we describe the design and the rationale of PRIME-HCC, a two-part multi-centre phase Ib study to assess safety and bioactivity of the nivolumab and ipilimumab combination before LR in patients with HCC.
PRIME HCC is a two-part, phase Ib study of ipilimumab and nivolumab combination prior to LR in adult patients (aged ≥18 years) with HCC. Ipilimumab will be administered once only on Day 1. Nivolumab will be administered on Day 1 and Day 22 (± 3 days) for a total of two 21-day cycles (i.e. 6 weeks of treatment). Part 1 of the study will initially consist of a safety run-in phase of 6 participants. If two or fewer surgical delays are observed, the study will continue to Part 2, which will consist of an expansion phase including up to 26 participants. All participants entered into the study will receive nivolumab and ipilimumab for a fixed duration of 6 weeks of treatment. The study flow-chart is summarized in Fig. 1.
Ipilimumab is a fully human monoclonal immunoglobulin (Ig) G1k specific for human CTLA-4 manufactured by Bristol Myers Squibb (BMS). Nivolumab is a human monoclonal antibody (HuMAb; immunoglobulin G4 [IgG4]-S228P) manufactured by BMS that inhibits the PD-1 receptor on cell surface. The clinical safety profile of nivolumab and ipilimumab as a combination therapy has emerged from a number of clinical studies in a number of tumour types [17,18,19,20,21,22].
In PRIME-HCC the dosing schedule adopted is 1 mg/kg dose Q6W for ipilimumab in combination with nivolumab 3 mg/kg Q3W for a total of 2 cycles. The rationale for dose selection stems from the clinical experience in the use of the combination across a number of indications. In the specific setting of HCC, whilst there is currently no clinical data available to illustrate the safety and tolerability of the planned regimen administered sequentially with LR, similar dosing schedules including a six-weekly dosing of ipilimumab at 1 mg/kg and three-weekly dosing of nivolumab at 3 mg/kg have been explored in CA209–040 cohort 4. Extrapolating from CA209–040 safety data, ipilimumab dose intensity appears to be the strongest determinant of toxicity, in particular with regards to immune-related liver TRAEs: study treatment in Arms B and C, where ipilimumab dose intensitiy was lower, was shown to be better tolerable compared to more intense ipilimumab dosing schedules (3 mg/kg in Arm A). For this reason, PRIME-HCC will utilise the lowest effective dose intensity schedule (1 mg/kg Q6W) and combine it with nivolumab at the clinically approved dose of 3 mg/kg Q3W. The choice of this combination will maintain individual exposures that are optimally consistent with those associated with maximal efficacy response in other indications and that are tolerated and safe, especially considering liver-related TRAEs in a patient population where cirrhosis and concomitant chronic viral infection is highly prevalent.
Detailed eligibility criteria are provided in Table 1. In brief, PRIME-HCC will recruit patients amenable to resection and ineligible for liver transplantation, with a confirmed diagnosis of HCC by biopsy or by non-invasive diagnostic criteria of the American Association for the Study of the Liver (AASLD).
Participants will require a full hepatitis serology screen prior to enrolment into the study, this includes Hepatitis B and Hepatitis C Virus serology. In patients with positive serology for either virus, baseline HBV DNA and HCV quantitative RNA levels will be requested. Participants who are confirmed to have chronic and active hepatitis B and/or C (i.e. with detectable HBV DNA or HCV RNA at baseline) will have their viral load (HCV RNA and/or HBV DNA as appropriate) monitored at each cycle and at the end of treatment follow-up visit.
Planned sample size and study period
We designed the study as a safety-oriented trial and considered enrolling a cohort of up to 32 participants to:
Comprehensively characterise the safety profile of nivolumab and ipilimumab co-administration in patients with early-stage HCC;
Preliminarily document the efficacy of treatment to inform subsequent efficacy-testing in a future adequately powered trial;
Obtain adequate information regarding the disease-modulating effects from treatment reflected by the proposed exploratory endpoints.
With the primary endpoint being safety, no power calculation for hypothesis testing is required to formally power the study: the upper 95% confidence interval for toxicity events will inform the decision to proceed to a future, adequately powered, phase II trial. Part 1 of the study will initially require a total of 6 patients. If ≤2 surgical. Delays are observed (primary safety endpoint), the study will continue to Part 2 following Independent Safety Data Monitoring Committee review of preliminary safety data. A second interim analysis will be performed when 100% of the recruited patients have completed study follow-up visit 2 (FU2) to evaluate general safety and tolerability of the combination.
Patients will undergo baseline tumour imaging including computed tomography (CT) scan of the chest, abdomen and pelvis, and by contrast enhanced magnetic resonance imaging (MRI) scan of the liver at screening. At post-treatment time-points prior to surgery (on Day 43), after surgery (on Day 127) and 4-monthly thereafter, tumour imaging will be repeated using contrast enhanced MRI. A triple-phase CT of the liver is an acceptable alternative for intrahepatic staging in patients with contraindications to MRI. Baseline CT/MRI scans do not need to be repeated if obtained within 35 days of first dose. The same method used for assessment at baseline must then be used at all subsequent time points. RECIST v1.1 criteria will be used to determine patient response to treatment, progression-free survival (PFS) and ORR. A baseline core tumor biopsy will be collected from participants at screening and patients will have a parcel of leftover tissue from their LR specimen stored for correlative studies. Treatment will consist of a maximum of 2 cycles of nivolumab 3 mg/kg and 1 cycle of ipilimumab 1 mg/kg administered intravenously Q3W. Patients will be reviewed following completion of IMP treatment (Follow-up visit 1; FU1) on Day 43 +/− 3, prior to surgery. LR will be performed as per standard of care. The safety FU2 will be conducted 126 days (± 7 days) after the first dose of the investigational medicinal product (IMP). All AEs that occur prior to the visit will be recorded. Participants with on-going AEs at the visit will be followed up by principal investigator (PI) or delegate until resolution or stabilisation of the event. Following FU2, participants will be assessed every 4 months (± 7 days) thereafter to collect information regarding disease status and survival. Long-term follow-up will continue, for each patient, for a total of 2 years. The Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) schedule of enrolment, interventions, and assessments is provided in Supplementary Table 1.
Outcome measures and endpoints
Primary study endpoints include rate of patients experiencing a surgery delay to Day 89 or later and determination of safety and tolerability of the nivolumab/ipilimumab combination based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0 criteria from nivolumab and ipilimumab initiation to 126 days later.
Secondary endpoints include ORR on pre-resection imaging at day 42 according to the RECIST v1.1 criteria and pathologic response rate on evaluation of the resected specimen. Exploratory endpoints are PFS rate and OS at day 126 and every 4 months thereafter and identity of biomarkers of response to nivolumab and ipilimumab using high-throughput technologies.
Adverse events management and dose modifications
Adverse events (both non-serious and serious) of unknown aetiology, associated with IMP exposure and likely to have an immune-mediated underlying mechanism may be considered as irAEs. These AEs may occur from soon after the first dose to months after the last dose. If an irAE is suspected, efforts will be put in place to exclude any other etiologic causes prior to labelling an AE as an irAEs. Summaries of recommendations to managing irAEs and of the physician’s guidelines for IMP’s temporary interruption and permanent discontinuation in case of toxicities are provided in Table 2 and Table 3, respectively. Treatment discontinuation for AST, ALT deterioration in participants who present with Grade 2 AST or ALT at Cycle 1 Day 1 will be triggered only if ALT or AST increase by more than or equal to 50% compared to the measurement taken at initiation of systemic treatment (Cycle 1 Day 1) and lasts for at least 1 week. In addition to the guidelines, dosing should be permanently discontinued in any participant who does not receive the Cycle 2 dose within the allowed window (Day 18 to Day 24) due to being unfit for dosing for any reason.
Statistical analyses will include an intent to treat (ITT) analysis including all participants enrolled and a per protocol analysis using all participants who complete the study without major protocol violations. Descriptive analyses will be performed by cross-tabulating relevant predictors (e.g. demographic variables) and endpoints. Appropriate statistical tests will be carried out, such as Fisher’s exact test for categorical variables and Wilcoxon tests for continuous variables. Univariable regression analyses will also be performed to estimate regression coefficients and their 95% confidence intervals. Data analysis will occur when the study is complete. Interim analyses of safety data will be conducted at the end of FU1 and at the end of FU2. The comprehensive statistical analysis plan will be finalised prior to the final analysis.
All participants who receive at least one dose of IMP will be included in the safety analysis set. All participants who receive at least one dose of the IMP and undergo disease re-evaluation as per protocol will be included in the efficacy analysis. Due to the exploratory nature of the study with regards to efficacy endpoints, pathologic response rates and RECIST 1.1 response rates will be presented descriptively. The exploratory endpoint of PFS rate will be shown with Kaplan-Meier plots using the full timespan from the start of IMP administration until the date of progression or death from any cause. Proportions of participants who do not progress and who are alive at Day 127 (FU2) and 4-monthly time-points thereafter will also be estimated. For the exploratory endpoints, appropriate descriptive analysis and univariable regression analysis will be conducted.
Alongside primary clinical endpoints, PRIME-HCC will generate a biorepository of peripheral blood, tissue, stool and urine samples collected at different study timepoints (Supplementary Table 2). Tissue samples pre- and post-immunotherapy will undergo multi-colour immune profiling to evaluate the expression of PD ligands and a panel of other immune checkpoints evaluated in co-expression with CD4, CD8, CD20, CD56, CD68 and FoxP3 to verify their immunologic role in relationship to the peri-tumoural infiltrate. Following macro-dissection and total RNA extraction, targeted transcriptomic profiling using the Nanostring PanCancer Immune panel will be used to evaluate enrichment of 770 genes pertaining to 24 immune cell types in pre-and post-treatment tissue samples. Peripheral blood mononuclear cells will be profiled using flow cytometry to differentiate relative abundance T-cytotoxic (CD3+/CD8+), T-helper (CD3+/CD4+/CD25−) and T-reg cells (CD3+/CD4+/CD25high) and downstream transcriptome analysis will decipher the relative functional contribution of individual T-cell subsets in influencing response to ICPI. Lastly, we will perform plasma and urinary metabolic phenotyping and stool metagenomic analysis to evaluate the contribution of the gut microbiota and associated metabolites in influencing response to neoadjuvant ICI therapy.
PD-1/PD-L1 inhibitors and CTLA-4 inhibitors, either alone or in combination represent a promising peri-operative therapeutic option. A single dose of pre-operative pembrolizumab, can induce near complete pathologic responses in 19% of stage III/IV resectable melanoma patients . Preliminary efficacy reports suggest even higher rates of complete pathologic response ranging from 7 to 45% from neoadjuvant nivolumab/ipilimumab therapy . In NSCLC, neoadjuvant checkpoint blockade leads to a higher proportion of major pathologic responses compared to chemotherapy  and the phase II NEOSTAR trial, has shown that treatment with nivolumab/ipilimumab leads to higher major pathological responses (33%) compared to nivolumab (17%) . Similar positive results have been seen in non-metastatic muscle-invasive bladder cancer, where two studies have reported complete response rates of 40 and 29% after up to 3 doses of anti-PD-1/PD-L1 monotherapy [27, 28]. A recent phase Ib study of sequential nivolumab/ipilimumab followed by surgery reported pathological complete responses in 45% of patients, although 54% of the patients experienced grade 3–4 immune-related adverse events (irAEs) . Importantly, alongside the efficacy data, no unexpected surgical delays/complications were reported, and the safety profile appeared improved over chemotherapy also in the neoadjuvant setting [23, 25, 26, 29].
The study of immune-checkpoint inhibitors in the preoperative setting of HCC is an ideal scenario to enable comprehensive evaluation of predictive correlates of response to treatment. Therapeutic expansion of immunotherapy to early stage patients, however, is accompanied by a number of clinical concerns that require to be addressed prospectively. Firstly, from a safety point of view, concurrent liver failure stemming from underlying cirrhosis and active hepatotropic viral infection makes the interaction between immune checkpoint inhibition and surgical resection a clinical scenario deserving comprehensive safety evaluation. Secondly, there is an inherent lack of efficacy data to confirm the sensitivity of early stage, treatment-naïve HCC patients to immune checkpoint inhibition. This is a highly relevant point in generalizing the efficacy of anti-PD-1/PD-L1 and anti-CTLA-4 agents across all the stages of HCC, especially given that the majority of patients that have been previously recruited to clinical trials of immune checkpoint inhibitors may have had loco-regional therapies (radiofrequency ablation or TACE). These treatments are widely renowned inducers of immunogenic cell death that might have exerted a priming effect on the immune system by facilitating a broader access to otherwise inaccessible neo-epitopes. Confirmation of the bioactivity of nivolumab in combination with ipilimumab in early stage HCC, where the biology of the disease may significantly differ from that of relapsed or advanced disease, is therefore an important research aim to allow optimal allocation of checkpoint blockade in the treatment paradigm of patients with HCC.
Despite optimal surgical control of the disease, patients with HCC are at high risk of recurrence after LR. Currently, there is no standard of care for neoadjuvant therapy, although a number of approaches have been attempted. The study of immune-checkpoint inhibitors in the preoperative setting of HCC is an ideal scenario to enable comprehensive evaluation of predictive correlates of response to anti-PD-1 and anti-CTLA-4 checkpoint inhibitors. The results of this study will help to define the role of neoadjuvant nivolumab/ipilimumab combination in the management of HCC, with potential to improve survival outcomes in this patient population.
