Background: Cancer(ca) and old age are risk factors for developing severe COVID-19 (C19+) disease, related morbidity and mortality. These patients (pts) were excluded from clinical trials evaluating the safety and efficacy of 3 FDA approved C19 vaccines (vax). Genitourinary (GU) ca-prostate, bladder and kidney ca contribute to the majority of non-skin ca and median age of these pts range from 65-75 yrs. We aimed to study these highly vulnerable pts behavior and outcomes regarding C19 vax in comparison to non-GU ca pts (18-89 years). Method(s): A prospective and observational single center study. Adult ca pts seen in clinics from Nov 2021-Sept 2022 were randomly interviewed using telephone surveys after a verbal consent. Type of ca and therapy data were collected from pts' medical records. The survey included C19 disease status, vax status positive (+) or negative (-), reason for vax status, side effects (s.e), impact on ca Rx or ca progression. Data was entered on REDCap. The primary end point was rate of vaccination in adult ca pts. Secondary end points were to quantify C19 vax acceptance vs. hesitance, identify s.e of C19 vax and effect of C19 vax on outcomes in GU and non-GU Ca pts. Result(s): N=172;GU ca 21 (12.2%) and non-GUca 151 (87.8%). Among GU ca pts- 9 had prostate ca, 7 had bladder ca and 5 had renal ca. C19+ in 4 (19%) GU and 45 (30.2%) non-GU pts. GU pts: 90.5% received C19 vax (Pfizer 47.6%;Moderna 42.9%, J & J 0%);9.5% were not vaxed. Non-GU pts: 85.2% received C19 vax (Pfizer 39.1%;Moderna 43%, J & J 2.6%);14.8% were not vaxed. The top 3 risk factors for serious C19+ were age >65yr (76.2%), heart disease (61.9%) and BMI.30 (42.9%) in GU ca pts and age >65yr (46.4%), BMI.30 (35.1%) and smoking (19.9%) in non-GU ca pts. The top 3 reasons for C19 vax (+) in GU ca pts: protection against C19+ for self (81%), for others (47.6%) and provider recommendation (38.1%). The main reasons for vax hesitancy in C19 vax (-) GU ca pts: concern for allergy to the vax (4.8%) and prior C19 infection (4.8%). The common s.e of C19 vax reported in GU ca pts were injection site inflammation (19%), headache (4.8%), muscle/body aches (4.8%) but no lymphadenopathy. None of GU ca pts reported delay in Rx or progression of the disease due to C-19 vax. Conclusion(s): C19 vax were overall well tolerated and did not impact ca outcomes in pts with GU malignancies. Oncologists should discuss the importance of C19 vax in the context of ca.

Introduction: The standard approach for relapsed or refractory (RR) classical Hodgkin lymphoma (cHL) following front-line treatment failure is second line therapy (SLT) aimed to achieve complete response (CR), followed by consolidation with high dose therapy and autologous hematopoietic cell transplantation (HDT/AHCT). No one standard SLT exists and options include regimens containing platinum, gemcitabine, and more recently brentuximab vedotin (BV). Complete response rates associated with these regimens range from 50-70%. Due to the increasing use of BV in the front-line setting, development of SLT regimens that are both highly effective and BV-sparing are needed. Programmed death-1 (PD-1) inhibitors are highly active in RR cHL and have the potential to enhance the efficacy of standard chemotherapy. Here we report the results of our phase II study evaluating a novel anti-PD-1-based regimen, pembrolizumab plus gemcitabine, vinorelbine, and liposomal doxorubicin (pembrolizumab-GVD), as SLT for RR cHL. Methods: Transplant eligible patients (pts) with RR cHL following failure of 1-line of therapy were eligible. Treatment consisted of 2 to 4 cycles of pembrolizumab (200mg IV, day 1), gemcitabine (1000mg/m2 IV, days 1 and 8), vinorelbine (20mg/m2 IV, days 1 and 8) and liposomal doxorubicin (15mg/m2, days 1 and 8), given on 21-day cycles. Pts who achieved CR by PET (Deauville ≤3) after 2 or 4 cycles proceeded to HDT/AHCT. HDT/AHCT was carried out according to institutional standards and BV maintenance was allowed following HDT/AHCT. The primary endpoint was CR rate after 2 or 4 cycles of pembrolizumab-GVD. Enrollment occurred according to a Simon 2-stage design with sample size based upon a projected CR rate of 70%. In stage 1, 23 pts enrolled and 12 or more CRs were required to proceed to stage II;in stage II, an additional 16 pts enrolled. Out of a total of 39 pts, 24 CRs were required to declare this regimen promising. Results: Among 39 patients enrolled, 37 are evaluable for toxicity (2 pts have not yet started treatment) and 34 are evaluable for response (4 pts too early, 1 pt found to have composite lymphoma after enrollment). Of 37 treated pts, median age is 36 (range 21-71), 43% are male, 23 (62%) had advanced stage disease, and 15 (41%) had primary refractory disease. With regard to RR cHL risk factors (B-symptoms, extranodal disease, and relapse/refractory disease within 1 year of initial treatment), 4(11%) had no risk factors (RFs), 21 (57%) had 1 RF, 9 (24%) had 2 RFs, and 3 (8%) had all 3 RFs. Treatment was well tolerated with most adverse events being grade 1 or 2 (see figure 1). Grade 3 AEs included rash (n=1), elevated AST/ALT (n=3), oral mucositis (n=2), and neutropenia (n=3). Figure 2 shows the outcome for all 37 treated pts. Among 34 evaluable pts, 31 (91%) achieved CR after 2 cycles and 3 achieved partial response. An additional 1 pt achieved CR after 4 cycles of pembrolizumab-GVD, therefore in total, 32 of 34 (94%) achieved CR following pembrolizumab-GVD. 4 pts with CR after 2 cycles received an additional 2 cycles of pembrolizumab-GVD in order to delay HDT/AHCT during the height of the COVID-19 pandemic (n=3) or due to refusing HDT/ASCT (n=1). To date, 32 have undergone HDT/AHCT following 2 (n=27) or 4 (n=5) cycles of treatment. 1 pt is awaiting HDT/AHCT;1 pt refused HDT/ASCT and received pembrolizumab maintenance instead. 2 pts received involved site radiation therapy to initial area of relapsed disease prior to planned HDT/AHCT and 10 pts received post-HDT/ASCT maintenance with BV. Median follow-up post-HDT/AHCT is 9 mos (range 0.03-20.9 mos) and all pts remain in remission to date. Conclusion: Second-line therapy with pembrolizumab-GVD is a highly effective and well-tolerated regimen that can efficiently bridge pts with RR cHL to HDT/AHCT. Updated results including all 39 enrolled pts will be presented at the meeting. Given the high CR rate observed with pembrolizumab-GVD, an expansion cohort evaluating 8 cycles of pembrolizumab maintenance (instead of HDT/AHCT) for patients who achieve CR af er 4 cycles of pembrolizumab-GVD is planned.
