e21006 Background: IPI (anti-CTLA4) is approved for treatment of advanced MEL in adults, and more information on efficacy and safety of IPI in younger patients (pts) is needed. Methods: Pts from study CA184-178 (NCT01696045) age 12 to <18 yrs with previously treated or untreated, unresectable stage III or IV malignant MEL received up to 4 doses of IPI at 3 or 10 mg/kg Q3W. Key exclusion criteria were ocular MEL, active brain metastases, or autoimmune disease. Primary endpoints were 1-yr overall survival (OS) and safety. Results: From April 2013 to June 2016, 12 pts received either IPI 3 mg/kg (n=4) or 10 mg/kg (n=8); 2 did not meet study criteria and were not treated. For the 3 and 10 mg/kg groups, median age was 13 yrs and 15 yrs, 50% and 63% were male, 25% and 13% had elevated baseline lactate dehydrogenase, and 75% and 50% had prior systemic therapy, respectively. Median number of IPI doses received was 4.0 (range: 2–4) for 3 mg/kg and 3.0 (range: 1–4) for 10 mg/kg. At 1 yr, 3/4 pts on 3 mg/kg and 5/8 pts on 10 mg/kg were alive (Table). Two pts on 10 mg/kg had partial response and 1 pt from each group had stable disease (Table). One pt had ongoing partial response >2 yrs without further treatment. Treatment-related grade 1-4 adverse events were reported in 2/4 and 7/8 pts in 3 and 10 mg/kg groups, respectively. There was 1 grade 3-4 immune-mediated adverse reaction with 3 mg/kg (hepatitis) and 5 with 10 mg/kg (hepatitis [2] and pyrexia [2] were most common). The study was stopped early due to slow accrual. Conclusions: At >1 yr of follow-up, IPI demonstrated activity in MEL pts aged 12 to <18 yrs, with a safety profile consistent with that observed in adults. Our trial highlights the difficulties of enrolling children with rare diseases in clinical trials for drugs that are approved in adults, suggesting adolescents should be included earlier in adult trials of promising new drugs.

e20532 Background: Recent clinical trials have shown positive results for therapies combining concurrent chemoradiation therapy (cCRT) and checkpoint immunotherapy in unresectable non-small cell lung cancer (NSCLC). cCRT is associated with an increased risk of pneumonitis, a severe and life-threatening inflammation of the lungs. To further inform clinical decision-making and support the evaluation of new therapies combining immunotherapies with cCRT, it is important to understand the baseline risk of pneumonitis associated with cCRT alone. The objective of this study was to quantify the incidence of cCRT-induced grade 3−5 pneumonitis (immune-mediated and radiation pneumonitis) in unresectable stage III NSCLC patients. Methods: A systematic literature review and meta-analysis were performed in accordance with PRISMA guidelines. MEDLINE, Embase, and the Cochrane Central Register were searched from 2014 to April 24, 2020. Chemotherapies of interest were cisplatin, pemetrexed, etoposide, carboplatin, and paclitaxel. Randomized controlled trials (RCTs), observational studies, and non-randomized trials were included. Bayesian meta-analysis using a binomial model random effects model was conducted with SAS 9.4. Results: Among 1,889 records identified from the search, 17 studies (6 RCTs, 8 observational studies, 3 single-arm trials) met inclusion criteria. Eleven studies were included in the meta-analysis (5 RCTs, 6 observational studies; 1,788 patients). All studies specified radiation-related pneumonitis (RP), although this is clinically indistinguishable from immune-mediated pneumonitis. Patient populations were comparable across studies; the most common chemotherapies were paclitaxel + carboplatin (n = 6) and pemetrexed + cisplatin (n = 5), and radiation doses ranged from 60–74 Gy. There was variation across studies in intervention, outcome reporting, and follow-up (median range: 12–73 months), but this variation was considered acceptable based on sensitivity analyses. The estimated pooled incidence of grade 3−5 RP in cCRT-treated unresectable stage III NSCLC patients was 3.62% [95% confidence interval (CI): 1.65−6.21] in RCTs and 5.98% [95% CI: 2.26−12.91] in observational studies. The pooled incidence of fatal (grade 5) RP was 0.37% [95% CI: 0−2.78] in RCTs and 1.73% [95% CI: 0.53−4.33] in observational studies. Conclusions: This study estimates that 3.62–5.98% of patients with unresectable stage III NSCLC develop grade 3−5 RP when treated with cCRT, with incidence varying by study design. Estimates of RP incidence were higher in the real-world setting compared to RCTs. These results can be used to contextualize the baseline risk of cCRT-induced pneumonitis in unresectable stage III NSCLC to better understand the adverse event of pneumonitis associated with novel immunotherapy treatments indicated for concomitant use with this modality.

e20104 Background: This exploratory single arm phase II study evaluated the efficacy and safety of RRx-001 followed by reintroduction of platinum plus etoposide in patients with previously treated small cell lung cancer (SCLC). Methods: Patients with SCLC that was platinum-resistant or received at least 2 prior lines were treated with RRx-001 4 mg IV on day 1 of each week of a 21-day cycle followed at progression by re-challenge with etoposide and cisplatin or carboplatin. The primary endpoints were overall survival (OS) and overall response rate to platinum therapy. Results: Between December 2016 and March 2018, 26 patients were enrolled and received at least one dose of RRx-001. The median number of prior lines of therapy was 2 (range 1-9) and 19 (73.1%) patients had platinum-resistant disease. In the intention-to-treat population, 1 (3.8%) achieved partial response (PR) and 7 (26.9%) had stable disease (SD) during treatment with RRx-001, whereas 1 patient (3.8%) had complete response and 6 (23.1%) had partial response on platinum plus etoposide. The estimated median and 12-month OS from enrollment were 8.6 months and 44.1%, respectively. The most common treatment-emergent adverse events from RRx-001 was mild discomfort at the infusion site (23%) and decreased appetite (15.3%). Conclusions: RRx-001 followed by re-challenge with platinum plus etoposide chemotherapy is feasible and associated with promising results. Clinical trial information: NCT02489903.

9010 Background: Consolidation PD-1/PD-L1 inhibition after chemoradiation (CRT) for unresectable stage III NSCLC improves overall survival. In stage IV NSCLC, the combination of nivolumab/ipilimumab improved overall survival compared to chemotherapy in patients with PD-L1 > 1% and performed favorably in patients with PD-L1 < 1%. The safety of consolidation nivolumab/ipilimumab after CRT has not been previously assessed. Methods: In this randomized, multi-center, phase II study, a total of 105 planned pts with unresectable stage IIIA/IIIB NSCLC will receive chemoradiation, then randomize 1:1 to either nivolumab 480mg IV q4 wks (Arm A) or nivolumab 3mg/kg IV q2 wks + ipilimumab 1mg/kg IV q6 wks (Arm B), for up to 24 wks. In this planned interim analysis, the safety of the first 50 patients, with 25 patients treated on each arm, is assessed. Results: From 9/2017 to 6/2019, the first 50 patients were accrued and analyzed for this planned safety analysis. Baseline characteristics for Arm A/B: median age 64/62, stage IIIA 17/16, stage IIIB 8/9, non-squamous 14/13, squamous 11/12. The median number of cycles completed in Arm A was 6 (range 1-6, cycle length q4 wks) and in Arm B was 4 (range 1-4, cycle length q6 wks). The rate of treatment-related adverse events leading to discontinuation of therapy was 16% in Arm A and 40% in Arm B. The percentage of patients with any > grade 3 adverse event (AE) was 32% in Arm A and 44% in Arm B. With respect to immune-related AE (irAEs), the percentage of patients with any ≥grade 2 was 44% in Arm A and 60% in Arm B; any ≥ grade 3 irAEs was 16% in Arm A and 32% in Arm B. The incidence of > grade 2 pneumonitis was 16% in Arm A and 36% in Arm B. The percentage of patients with > grade 3 pneumonitis was 4% in Arm A and 20% in Arm B. No treatment-related deaths were reported on either arm. Conclusions: In the post chemoradiation setting, the incidence of > grade 3 toxicity was greater in the consolidative nivolumab/ipilimumab arm, which resulted in a higher rate of treatment discontinuation than nivolumab alone. The Data and Safety Monitoring Board recommended continued enrollment without modification to the trial and the study currently remains open to accrual (66 of 105 patients have been enrolled as of 1/17/2020). Clinical trial information: NCT03285321.

<b>Purpose:</b> Patients with advanced endometrial carcinoma have limited treatment options. We report final primary efficacy analysis results for a patient cohort with advanced endometrial carcinoma receiving lenvatinib plus pembrolizumab in an ongoing phase Ib/II study of selected solid tumors. <b>Methods:</b> Patients took lenvatinib 20 mg once daily orally plus pembrolizumab 200 mg intravenously once every 3 weeks, in 3-week cycles. The primary end point was objective response rate (ORR) at 24 weeks (ORRWk24); secondary efficacy end points included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Tumor assessments were evaluated by investigators per immune-related RECIST. <b>Results:</b> At data cutoff, 108 patients with previously treated endometrial carcinoma were enrolled, with a median follow-up of 18.7 months. The ORRWk24 was 38.0% (95% CI, 28.8% to 47.8%). Among subgroups, the ORRWk24 (95% CI) was 63.6% (30.8% to 89.1%) in patients with microsatellite instability (MSI)-high tumors (n = 11) and 36.2% (26.5% to 46.7%) in patients with microsatellite-stable tumors (n = 94). For previously treated patients, regardless of tumor MSI status, the median DOR was 21.2 months (95% CI, 7.6 months to not estimable), median PFS was 7.4 months (95% CI, 5.3 to 8.7 months), and median OS was 16.7 months (15.0 months to not estimable). Grade 3 or 4 treatment-related adverse events occurred in 83/124 (66.9%) patients. <b>Conclusion:</b> Lenvatinib plus pembrolizumab showed promising antitumor activity in patients with advanced endometrial carcinoma who have experienced disease progression after prior systemic therapy, regardless of tumor MSI status. The combination therapy had a manageable toxicity profile. <b>Trial registration:</b> ClinicalTrials.gov NCT02501096.

Purpose: Purine analogs and alkylators are important agents in the treatment of chronic lymphocytic leukemia (CLL). Previously, combinations of fludarabine and chlorambucil were abandoned because of increased toxicity from overlapping myelosuppression and immunosuppression. Of the purine analogs active in CLL, pentostatin may be least myelosuppressive. We hypothesized that combining pentostatin with cyclophosphamide would have less myelotoxicity than combinations using other purine analogs. Patients and Methods: We studied 23 patients with previously treated CLL. All patients received pentostatin 4 mg/m2. Seventeen patients received cyclophosphamide 600 mg/m2, and six patients received cyclophosphamide 900 mg/m2. Both drugs were administered on day 1 of each cycle, and cycles were repeated every 3 weeks for six treatments. Filgrastim, sulfamethoxazole/trimethoprim, and acyclovir were administered prophylactically. The median number of prior treatment regimens was three (range, one to five) with 13 patients (57%) refractory to prior fludarabine therapy. Results: The cyclophosphamide 900 mg/m2 dose level was associated with moderate to severe nausea, and we chose cyclophosphamide 600 mg/m2 as the dose for further study. There were 17 responses (74%; 95% confidence interval, 63% to 85%), including four complete responses. The response rate was 77% in fludarabine-refractory patients. Myelosuppression was acceptable with grade 3/4 neutropenia and thrombocytopenia, seen in 35% and 30% of patients, respectively. The relative sparing of thrombopoiesis can be seen in that only one patient (5%) with an initial platelet count of more than 20,000 required platelet transfusions while receiving therapy. Conclusion: Pentostatin 4 mg/m2 with cyclophosphamide 600 mg/m2 is safe and effective in previously treated patients with CLL. On the basis of these results, we are currently studying pentostatin, cyclophosphamide, and rituximab (PCR) therapy in patients with CLL.

9500 Background: The phase 3 double-blind EORTC 1325/KEYNOTE-054 trial evaluated pembrolizumab (pembro) vs placebo in stage III cutaneous melanoma patients (pts) with complete resection of lymph nodes. Pembro improved RFS (hazard ratio [HR] 0.57) and DMFS (HR 0.60) (Eggermont, NEJM 2018, TLO 2021). In the pembro group, the incidence of immune related AE (irAE) grade 1-5 was 37%, and of grade 3-5 was 7%. We present the safety profile, response rate and PFS for the subset of pts who had a recurrence and crossed over or were rechallenged with pembrolizumab, within protocol. Methods: Pts were randomized to receive iv. pembro 200 mg (N=514) or placebo (N=505) every 3 weeks for a total of 18 doses (~1 year). Upon recurrence with no brain metastases, pts with an ECOG PS 0-2 were eligible to enter part 2 of the study, i.e. to receive pembro 200 mg iv. every 3 weeks for a maximum of 2 years, for crossover (those who received placebo) or rechallenge (those who recurred ≥6 months after completing one year of pembro therapy). Treatment was stopped in case of disease progression (RECIST 1.1) or unacceptable toxicity. Results: At the clinical cut-off (16-Oct-2020), 298 (59%) pts had a disease recurrence in the placebo group; 155 pts participated in the crossover part 2 of the trial. A total of 297 (58%) pts completed the 1-yr pembro adjuvant treatment, of whom 47 had a recurrence ≥6 mths from the stop of treatment and 20 entered in the rechallenge part of the trial. Among 175 pts who started pembro in Part 2, 160 discontinued due to completion of therapy (N=24), disease progression (N=88), toxicity (N=20), investigator's decision (N=21), or other reason (N=7); 15 pts were still on-treatment. Results for the 2 groups are provided in the table. The median number of doses was 12 and 5.5, respectively (resp), and the median follow-up was 41 and 19 mts, resp. Among the 175 pts, 51 (29%) had a grade 1-4 irAE (by group: 47 [30%] and 4 [20%] resp) and 11 (6%) a grade 3-4 irAE. Conclusions: Pembrolizumab treatment after crossover yielded a 39% ORR in evaluable pts and an overall 3-yr PFS of ̃32%, but after rechallenge the efficacy was lower. Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA The median PFS (95% CI) from start of Part 2 was 14 (5-27) and 8 (5-15) mts for stage III-resected and III/IV various, resp. Among the 80 stage IV crossover pts with evaluable disease, 31 (39%) had an objective response: 14 (18%) CR, 17 (21%) PR. The 2-yr PFS rate from response was 69% (95% CI 48-83%). For these 80 pts, the median PFS was 6.1 mts and the 3-yr PFS rate was 31% (95% CI 21-41%). Among 9 stage IV rechallenged pts with an evaluable disease, 1 (11%) reached CR, 3 had SD and 5 PD.

PURPOSE: Liposomal anthracyclines are the present standard treatment for advanced AIDS-related Kaposi's sarcoma (KS). No effective therapies have been defined for use after treatment failure of these agents. A phase II trial was thus conducted with paclitaxel in patients with advanced KS to assess safety and antitumor activity. MATERIALS AND METHODS: A regimen of paclitaxel at a dose of 100 mg/m2 was given every 2 weeks to patients with advanced AIDS-related KS. Patients were treated until complete remission, disease progression, or unacceptable toxicity occurred. RESULTS: Fifty-six patients with advanced AIDS-related KS were accrued. Tumor-associated edema was present in 70% of patients and visceral involvement in 45%. Forty patients (71%) had received prior systemic therapy; 31 of these were resistant to an anthracycline. The median entry CD4+ lymphocyte count was 20 cells/mm3 (range, 0 to 358). A median of 10 cycles (range, 1 to 54+) of paclitaxel was administered. Fifty-nine percent of patients showed complete (n = 1) or partial response (n = 32) to paclitaxel. The median duration of response was 10.4 months (range, 2.8 to 26.7+ months) and the median survival was 15.4 months. The main side effects of therapy were grade 3 or 4 neutropenia in 61% of patients and mild-to-moderate alopecia in 87%. CONCLUSION: Paclitaxel at 100 mg/m2 given every 2 weeks is active and well tolerated in the treatment of advanced and previously treated AIDS-related KS. The median duration of response is among the longest observed for any regimen or single agent reported for AIDS-related KS. Paclitaxel at this dosage and schedule is a treatment option for patients with advanced AIDS-related KS, including those who have experienced treatment failure of prior systemic therapy.

Abstract The decision to treat indolent B-cell NHL is often based on progression of the disease. Most regimens have utilized fludarabine as the purine analog but the myelosuppression and immunosuppression of fludarabine combinations frequently results in severe infections. Combination therapy with pentostatin (P), a purine analog, cyclophosphamide (C), a DNA alkylator, and rituximab (R), an anti-CD20 monoclonal antibody, based on the single-agent activities, documented synergy, and non-overlapping toxicity profiles, may represent a promising approach in the treatment of these patients. To further investigate the efficacy of the PCR regimen for the treatment of indolent NHL, we conducted a phase II study. Patients diagnosed of bulky stage II, stage III/IV low-grade NHL (REAL classification), previously untreated or treated, were eligible. All patients were treated with intravenous infusions of P (4 mg/m2), C (600 mg/m2), and R (375 mg/m2) on day 1 of a 21-day cycle for at least 8 cycles. 2 additional cycles were given for patients with PR or SD after cycle 8 or patients with CR/CRu first evident at cycle 8. Clinical evaluation was performed after cycles 2, 4, 6, 8, and 10 if necessary. Dose modification for hematologic toxicity may be increased to the previous higher level when a hematologic toxicity returned to normal. Two 25% dose reductions or one 50% dose reduction were allowed for nonhematologic toxicity. One hundred patients with indolent NHL, 68 previously untreated, 26 previously treated, and 6 with unknown treatment history, were enrolled in the study. The median age was 61 years (range 29–84) and 63.4% were ECOG PS 0, 36.6% PS1. A total of 550 cycles were given, with a median of 6 cycles per patient. 8 patients were not evaluated for response due to withdrawal of consent (n=1), unacceptable toxicities (n=3), and missing data (n=4). 92 patients received at least two cycles of treatment and were evaluated for response. The highest response rate (RR) achieved was 68%, with 10 (10%) CR, 12 (12%) CRu, 46 (46%) PR, 23 (23%) SD, and 1 (1%) disease progression. Stratified according to previous treatment status, patients with previously untreated NHL had an RR of 47% (CR, CRu 17%) while that of the previously treated was 17% (CR 7%). 14 (14.0%) patients discontinued treatment due to toxicities. Grade 3/ 4 hematological adverse events documented included 10 grade 4 and 16 grade 3 neutropenia. Infectious complications were noted in 8 patients including 3 grade 3 febrile neutropenia, 2 grade 4 febrile neutropenia, and 3 grade 3 infections. A total of 4 deaths were recorded, including 1 due to acute myocardial infarction, 1 suspected cardiac event and 2 unknown causes. This immunochemotherapeutic regimen is active in patients with indolent NHL. The study is currently on-going and updated results will be presented.

Abstract Background CC chemokine receptor 4 (CCR4) is the receptor for macrophage-derived chemokine (MDC/CCL22) and thymus activation-regulated chemokine (TARC/CCL17). CCR4 is expressed on tumour cells in approximately 30-65% of patients with PTCL (Ogura, 2014). PTCL-NOS patients who are CCR4 positive have been reported to have a poorer prognosis compared to CCR4 negative patients (Ishida T CCR 2004). Mogamulizumab (KW-0761) is a defucosylated, humanized, IgG1 Mab with enhanced antibody dependent cellular cytotoxicity, that binds to CCR4. Mogamulizumab was evaluated in both phase 1 and 2 trials in Japanese patients. A phase II trial in PTCL and cutaneous T-cell lymphoma (CTCL) patients (Ogura, 2014) reported an overall response rate (ORR) of 35% in patients who relapsed after last systemic therapy (ORR was 34% in PTCL), leading to its approval in Japan in patients with previously treated CTCL and PTCL, in addition to its first indication, previously treated adult T-cell leukemia-lymphoma. Here we report the preliminary results of a European phase II trial of mogamulizumab in patients with relapsed/refractory PTCL. Methods A multi-center phase II study of mogamulizumab monotherapy was conducted to determine efficacy, safety and immunogenicity in patients with CCR4+ PTCL. The primary endpoint was ORR and secondary endpoints included duration of response, progression-free survival (PFS) and overall survival (OS). At least 34 evaluable patients were needed to detect a significant improvement over 15% assuming 80% power and a 0.0240 alpha significance level (assumes 35% ORR for alternative). Patients received mogamulizumab once weekly for 4 weeks and subsequently once every 2 weeks until progressive disease (PD) or unacceptable toxicity at a dose of 1.0 mg/kg. Responses were assessed every 8 weeks according to IWG criteria (Cheson et al 2007). Results Based on a preliminary analysis of the data, a total of 38 patients received at least one administration of mogamulizumab and were evaluable for safety analysis; (Male/female 23/15 ;Median age 58.5 years (range 19-87)). Three patients are still ongoing in the study (1 complete response (CR) and 2 stable disease (SD)). ECOG performance status at baseline was 0 (32%); 1 (29%); 2 (39%) and 92% of patients had stage III (32%) or IV (61%) disease. The median number of prior treatments was 2 (range 1-8). Only 17 patients (49%) responded to the last treatment administered prior to study entry. The median number of mogamulizumab administrations was 6 (range 1-32). The majority of adverse events (AEs) were CTCAE grade 1-2. Skin rash related to drug was observed in 32% of patients (12/38) and related AEs > grade 3 occurred in 32% (12) of patients. Infusion related reactions occurred in 3 patients (2 were CTCAE grade 2 and 1 was grade 3). Thirty-five patients were evaluable for efficacy. The ORR rate was 11% and the stable disease rate was 34% with a SD or better rate of 46%. The response by histological subtype is specified in the table below. The median duration of response (including SD) is 2.9 months. The median PFS is 2.1 months. Two patients (ALCL-ALK-neg and PTCL-NOS) proceeded to allogeneic SCT. Although the ORR in this study was less than seen in the Japanese study, the PFS was comparable. There were differences in patient population/study conduct between the Japanese study and this study, respectively, which included: inclusion of only relapsed patients (100% vs 49%), ECOG PS 2 (0% vs 39%) and response assessments (after 4 and 8 weeks versus 8 weekly from week 8). Conclusions Based on preliminary data, mogamulizumab demonstrates a SD or better rate of 46% and an ORR of 11% with an acceptable safety profile in this phase II study of heavily pre-treated relapsed/refractory PTCL patients.

17042 Background: Good PS patients (pts) with locally advanced NSCLC treated with concurrent chemoradiotherapy have a 20–40% 3 year survival. Treatment is arduous and poor PS or high risk pts often cannot complete a full course of treatment. The optimal combination of chemotherapy and radiation and the role of consolidation chemotherapy are unknown. Despite response rates exceeding 50%, most pts eventually progress with brain as the first site of relapse in up to 30%. Continuous infusion chemotherapy is better tolerated than intermittent chemotherapy combined with radiation and may improve outcome in other locally advanced aerodigestive malignancies, however it has not been studied extensively in NSCLC. Topotecan is active in NSCLC, can safely be combined with radiation, can be given by continuous infusion and penetrates the CNS making it an attractive study agent in locally advanced NSCLC. Methods: In this pilot study, 20 pts were treated with infusional topotecan 0.4 mg/m2/d with 3D conformal radiation to 63 Gy both delivered M-F for 7 weeks. Pts without progressive disease underwent consolidation chemotherapy with etoposide and platinum for one cycle to take advantage of upregulation of topoisomerase II by topotecan. Two cycles of docetaxel consolidation followed. Study endpoints include response, time to progression, survival, toxicity and development of CNS metastases. Results: All pts have completed induction chemoradiotherapy. 12/20 have completed consolidation. 17/20 pts had a PR and 1/20 SD after induction chemoradiation. 1 pt developed CNS metastases 228 days after study entry and is alive with disease at 541 days. 3 pts had pulmonary emboli. Therapy has been well tolerated with 1/20 grade 4 lymphopenia. Grade 3 hematologic toxicity was seen in 17/20 pts. Other grade 3 toxicities include esophagitis (3/20), esophageal stricture (2/20), pneumonitis (6/20), fatigue (6/20), weight loss (1/20). Conclusion: Continuous infusion topotecan with radiation is well tolerated and shows evidence of activity in the management of poor risk patients with unresectable stage III NSCLC. Survival data will be presented at the meeting. No significant financial relationships to disclose.
