PURPOSE Anti–programmed death-1 (PD-1) monotherapy induces a high response rate in patients with relapsed/refractory classic Hodgkin lymphoma (cHL), but complete remission (CR) is infrequently observed. As decitabine is known to boost T-cell function, we assessed the safety and efficacy of anti–PD-1 camrelizumab alone versus decitabine-primed camrelizumab in patients with relapsed/refractory cHL. METHODS This two-arm, open-label, phase II study enrolled patients with relapsed/refractory cHL who had received at least two lines of previous therapy. Anti–PD-1 treatment-naïve patients were randomly assigned (1:2) to camrelizumab (200 mg) monotherapy or decitabine (10 mg/d, days 1 to 5) plus camrelizumab (200 mg, day 8) combination therapy every 3 weeks. Patients who were previously treated with anti–PD-1 were assigned combination therapy. Primary end point was CR rate and safety. RESULTS Overall, 86 patients were enrolled and evaluated for response, with a median follow-up of 14.9 months. In anti–PD-1–naïve patients, CR rate was 32% (six of 19 patients) with camrelizumab monotherapy versus 71% (30 of 42 patients) who were administered decitabine plus camrelizumab ( P = .003). At the time of analysis, the response duration rate at 6 months was 76% on camrelizumab monotherapy versus 100% on decitabine plus camrelizumab. For patients who were previously treated with anti–PD-1, 28% achieved CR and 24% partial response after decitabine plus camrelizumab. Ten patients maintained a response at more than 6 months and 81% of responders were estimated to have a response at more than 1 year. For both treatments, the most common adverse events were clinically inconsequential cherry hemangiomas and leukocytopenia that were self-limiting. CONCLUSION CR rate in patients with relapsed/refractory cHL who were clinically naïve to PD-1 blockade was significantly higher with decitabine plus camrelizumab than with camrelizumab alone. Decitabine plus camrelizumab may reverse resistance to PD-1 inhibitors in patients with relapsed/refractory cHL.

BackgroundAvelumab, a human anti–PD-L1 monoclonal antibody, has shown a manageable safety profile and antitumor activity in multiple tumor types, including platinum-resistant metastatic or recurrent NSCLC,1 and is approved for patients with locally advanced or metastatic UC who have progressed after ≥1 previous line of platinum-based chemotherapy2 3 and as maintenance treatment for those who have not progressed with platinum-based chemotherapy.4 JAVELIN Medley VEGF (NCT03472560) evaluated the efficacy and safety of avelumab + axitinib, a potent inhibitor of VEGFR 1, 2, and 3, in patients with advanced or metastatic NSCLC or UC.MethodsEligible patients with NSCLC had received ≥1 prior platinum-containing therapy and ≤2 prior lines of systemic therapy for locally advanced or metastatic disease; patients with UC were treatment naive in the locally advanced or metastatic setting and ineligible for cisplatin-containing chemotherapy. Patients were immune checkpoint inhibitor naïve and received avelumab 800 mg intravenously every 2 weeks + axitinib 5 mg orally twice daily. The primary endpoint was confirmed objective response (OR) per investigator assessment (RECIST 1.1). Secondary endpoints included progression-free survival (PFS) and safety. PD-L1 expression was assessed in baseline tumor samples (Ventana SP263 assay). Data have not undergone standard quality checks and are subject to change due to COVID-19–related healthcare burden.ResultsA total of 41 patients with NSCLC and 20 with UC received avelumab + axitinib. The confirmed OR rate was 31.7% (95% CI, 18.1–48.1) in the NSCLC cohort and 10% (95% CI, 1.2–31.7) in the UC cohort (all partial responses); 16 patients (39.0%) and 5 (25.0%) had stable disease, respectively. Responses were observed regardless of PD-L1 expression status. Median PFS was 5.5 months (95% CI, 2.5–7.0) in the NSCLC cohort and 2.3 months (95% CI, 1.8–5.6) in the UC cohort. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 24 patients (58.5%) in the NSCLC cohort; the most common was hypertension (n=7 [17.1%]). Grade ≥3 TRAEs occurred in 9 patients (45.0%) in the UC cohort; the most common were amylase increased, asthenia, decreased appetite, and palmar-plantar erythrodysesthesia syndrome (n=2 [10%] each). One patient in each cohort experienced a TRAE that led to death (gastric perforation and urinary bladder hemorrhage).ConclusionsAvelumab + axitinib showed antitumor activity and a manageable safety profile in patients with advanced or metastatic NSCLC or UC consistent with findings from studies of each drug alone and in combination.Trial RegistrationNCT03472560Ethics ApprovalThe study was approved by each site’s independent ethics committee.ConsentN/AReferencesGulley JL, Rajan A, Spigel DR, et al.

209 Background: Immunotherapy approaches, including immune checkpoint blockade, have shown initial promising results in HCC. Anti PD-1 therapy with pembrolizumab has demonstrated antitumor activity and manageable safety in multiple cancers. KEYNOTE-224 (NCT02702414), an open label, phase 2 trial assessed the efficacy and safety of pembrolizumab in pts with advanced HCC previously treated with sorafenib. Methods: Eligible pts were age ≥18 y with confirmed HCC, radiographic progression after sorafenib and disease not amenable to curative treatment, Child Pugh A, ECOG PS 0-1 and predicted life expectancy > 3 mo. Pts received pembrolizumab 200 mg Q3W for 2 y or until disease progression, unacceptable toxicity, withdrawal of consent or investigator decision. Response was assessed every 9 wk (RECIST v1.1, central review). Primary endpoint was ORR (RECIST v1.1, central review). Secondary endpoints included DOR, DCR, PFS, OS, and safety and tolerability. Data cutoff date was Aug 24, 2017. Results: Of 104 treated pts, 23 continued therapy (median follow up 8.4 mo, range 0.4-13.6). Median age of pts was 68y (range 43-87), 21.2% were HBV+, 26% were HCV+, 94.2% were Child Pugh A, 79.8% had PD on sorafenib and 63.5% had extrahepatic disease. ORR was 16.3% (95% CI, 9.8 to 24.9) and similar across subgroups with different etiology. Median time to response was 2.1 mo (range 1.8-4.8) and 94% of responders were estimated to have a response duration ≥6 mo. Best responses were CR in 1 patient (1.0%), PR in 16 (15.4%), SD in 47 (45.2%) and PD in 34 (32.7%); DCR was 61.5%. Median PFS was 4.8 mo (95% CI, 3.4 to 6.6) and median OS (9.4 to NA) was not reached. The 6 mo PFS and OS rates were 43.1% and 77.9%, respectively. Treatment related (TR) AE occurred in 73.1% of pts; fatigue (21.2%) and increased aspartate aminotransferase (12.5%) were seen in ≥10% of pts and grades 3-5 TRAE in 25% including 1 death (ulcerative esophagitis). No cases of HBV/HCV flare occurred; immune mediated hepatitis occurred in 3 (2.9%) pts. Conclusion: Pembrolizumab treatment resulted in durable responses and favorable PFS and OS in pts with advanced HCC previously treated with sorafenib. Safety was generally comparable to that established for pembrolizumab monotherapy. Clinical trial information: NCT02702414.

4076 Background: C+A combination therapy displayed high objective response rate, disease control rate, and durable response with a manageable safety profile in patients (pts) with advanced HCC. Here we performed an updated analysis of OS to characterize the OS benefit of C+A in HCC pts. Methods: 70 pts in first-line cohort and 120 pts in second-line cohort were enrolled. Median OS and 2-year OS rate were evaluated via updated data (data cutoff, 3 January, 2021). Median time from enrollment to data cutoff of the total population (N = 190) was 29.1 months (range, 24.0-33.7). Results: OS events had occurred in 58.6% pts in first-line cohort and 60.0% pts in second-line cohort. The median OS was 20.1 months (95% CI, 14.9-NR) and 2-year OS rate was 43.3% (95% CI, 31.3-54.7) in first-line cohort. The median OS was 21.8 months (95% CI, 17.3-26.8) and 2-year OS rate was 44.6% (95% CI, 35.5-53.3) in second-line cohort. Conclusions: Long-term follow-up of C+A demonstrated remarkable survival benefit in advanced HCC pts, which further suggested that C+A is a promising combination therapy in advanced HCC pts. Clinical trial information: NCT03463876.
