Safety and Efficacy of Ipilimumab 10 Mg/Kg Among Patients with Advanced Melanoma from Italy Enrolled in a European Compassionate Use Program

BackgroundTreatment options are limited for patients with advanced melanoma who have progressed on checkpoint inhibitors and targeted therapies such as BRAF/MEK inhibitors (if BRAF-V600E mutated). Adoptive cell therapy utilizing tumor-infiltrating lymphocytes (TIL) has shown antitumor efficacy with durable responses in heavily pretreated melanoma patients. Safety and efficacy of lifileucel, a centrally manufactured cryopreserved autologous TIL therapy assessed by both investigator and an independent review committee (IRC), are presented.MethodsC-144-01 is a global Phase 2 open-label, multicenter study of the safety and efficacy of lifileucel in patients with unresectable metastatic melanoma. We report on Cohort 2 (N = 66) patients with Stage IIIC/IV unresectable melanoma who received lifileucel. Tumors resected at local institutions were processed in central GMP facilities for TIL production in a 22-day process. Final TIL infusion product was cryopreserved and shipped to sites. Patients received one week of cyclophosphamide/fludarabine preconditioning lymphodepletion, a single lifileucel infusion, followed by up to 6 doses of IL-2. All responses were assessed by RECIST 1.1.Results66 patients had the following baseline characteristics: 3.3 mean prior therapies (anti-PD1 100%; anti-CTLA-4 80%; BRAF/MEK inhibitor 23%), relatively high tumor burden (106 mm mean target lesion sum of diameters), 44% with liver and/or brain lesions, median LDH 244 U/L. Objective Response Rate (ORR) by investigator was 36.4% (2 CR, 22 PR, 1 previously confirmed PR is now changed to SD) and Disease Control Rate (DCR) of 80.3%. At a median follow up of 9.7 months, median Duration of Response (DOR) has not been reached. The adverse event profile was generally consistent with the underlying advanced disease and the profile of the lymphodepletion and IL-2 regimens.The ORR per IRC was 34.8% (2 CR, 21 PR) and DCR was 72.7%. At a median follow up of 6.9 months, the median IRC DOR has not been reached. Overall concordance rate of investigator and IRC read of response was 89.4%. The concordance compares favorably with literature reports in a metastatic disease.1ConclusionsLifileucel treatment resulted in a 36.4% ORR in heavily pretreated metastatic melanoma patients with high baseline disease burden who had received prior anti-PD1 and BRAF/MEK inhibitors, if tumor BRAF mutated. The high concordance of 89.4% between investigator and IRC confirms the original assessment of lifileucel efficacy in metastatic melanoma.2AcknowledgementsThe authors would like to thank the patients and their families for participation in the study.The authors would also like to acknowledge the support and dedication of all investigators and site team members from all participating clinical trial institutions.Trial RegistrationClinicalTrials. gov Identifier: NCT02360579Ethics ApprovalEthics Approval This trial was approved by Western Institutional Review Board - IRB Tracking Number: 20160198.ReferencesGhiorghiu DC, et al.

10026 Background: Clinical trials of immunotherapy exclude patients (pts) with pre-existing AD. While retrospective data exist regarding the efficacy and safety of single agent ipi and anti-PD1 antibodies (PD1) in pts with AD, no data are available regarding the safety and efficacy of combination therapy in pts with AD, which has a higher toxicity risk. Methods: Pts with melanoma and pre-existing AD treated with combination ipi/PD1 were retrospectively identified from 10 international centres. Data regarding AD, treatment, toxicity and outcomes were examined. Results: Fifty-five pts were included, 46 were treated with ipi/nivolumab and 9 with ipi/pembrolizumab. 40 had an ipi dose of 3mg/kg while 15 had a lower dose regimen. 9 pts received prior PD1 therapy; 3 suffered moderate immune-related adverse events (irAE) with no flares of AD on single agent PD1. Pre-existing AD included inflammatory bowel disease (IBD), thyroiditis, rheumatoid arthritis (RA), multiple sclerosis and psoriasis. 10 pts had active symptoms of AD and 13 were immunosuppressed at commencement of ipi/PD1. Eighteen pts (33%) experienced a flare of their AD including 4/7 with RA, 3/6 with psoriasis, 5/9 with IBD, 3/18 with thyroiditis, 1/1 with Sjogren’s syndrome, 1/1 with polymyalgia, 1/1 with Behcet’s syndrome. Median time to flare was 19 days (range 4 – 167). 13 pts were managed with steroids, 5 required additional immunosuppressants. 7 pts were hospitalised for management of flare (5 with IBD, 2 with RA). 2 pts required intensive care and vasopressors for severe IBD flare, quiescent prior to ipi/PD1. One for diarrhoea and shock and one for duodenal perforation. 8 pts ceased treatment due to flare (3 with IBD, 2 with RA, 1 with Behcet’s, 1 with Sjogren’s). Thirty-seven pts (67%), experienced an irAE unrelated to their AD, 38% G3 or G4. The most frequent irAEs were colitis (n = 16), hepatitis (n = 12), endocrinopathies (n = 12), with 13 pts experiencing an irAE in ≥ 2 organs. 9 pts experienced both AD flare and an irAE. 20 pts (36%) ceased immunotherapy due to irAEs. ORR was 55% (54% in PD1 naive pts), at a median follow up of 14 months, 77% of responses ongoing. ORR in pts who had a flare of their AD was 44% and in pts on immunosuppression was 46%. Median PFS was shorter in pts who had a flare of AD compared with those who did not (2.6 vs 9 months; P-value 0.047). Conclusions: Combination ipi/PD1 shows efficacy comparable to clinical trial populations in pts with pre-existing AD and advanced melanoma. Whilst there was a substantial risk of flare of AD, no increased frequency of irAE’s was observed.
