7545 Background: Obinutuzumab (G)-chemotherapy (chemo) has demonstrated improved progression-free survival compared with rituximab (R)-chemo in previously untreated advanced follicular lymphoma (FL). G is currently administered by IV infusion over ̃3–4 hours. A shorter duration of infusion in Cycle (C) 2 and subsequent cycles, as is standard practice with R, could improve convenience for patients (pts) and efficiency for infusion facilities. We report the primary analysis of the prospective, open-label, multicenter, single-arm, Phase IV, GAZELLE study (NCT03817853), which evaluated the safety of G administered as a 90-minute (min) SDI from C2 onwards in pts with FL. Methods: Pts with previously untreated FL received G (1000mg) intravenously on Day (D) 1, 8, and 15 of C1, and on D1 thereafter, plus chemo (bendamustine, CHOP, or CVP) for 6–8 cycles. In C1, pts received G at the standard infusion rate. Pts without a Grade (Gr) ≥3 infusion-related reaction (IRR) in C1 were eligible to receive G as a 90-min SDI from C2. Pts with a Gr 3 IRR in C1 received the standard G infusion in C2, and were eligible for G SDI in subsequent cycles if no Gr ≥3 IRRs occurred. Pts with a second Gr 3/4 IRR discontinued G. At the end of induction (EOI), responding pts received maintenance G (1000mg) as SDI for 2 years or until disease progression (PD). The primary endpoint was incidence of Gr ≥3 IRRs during C2. IRRs were defined as any event occurring ≤24 hours from infusion judged to be related to treatment. Secondary endpoints included adverse events (AEs) and investigator-assessed overall response rate at EOI. Results: As of December 3, 2020, 113 pts had received study treatment. Median age was 62.0 years, 50.4% were male, 61.9% had stage IV FL, and 45.1% were classified as high-risk FLIPI. Of the 110 pts who were eligible for G SDI from C2, no pt experienced a Gr ≥3 IRR with SDI in C2 (Table). One pt experienced a Gr 3 IRR with SDI in C5, presenting hypertension. All other IRRs with SDI were Gr 1/2. No Gr 4/5 IRRs were reported. Other AEs were similar to those observed in previous studies. At the clinical cut-off date, 104 pts had a CT imaging-based response assessment at EOI and 9 pts had no response assessment; 76/113 (67.3%) had a complete response, 22 (19.5%) had a partial response, and six (5.8%) had PD. Conclusions: In GAZELLE, G SDI in C2 and beyond appeared to be safe. No Gr 3 IRRs were observed in C2 and only one Gr 3 IRR was reported in subsequent cycles. The safety profile of G SDI was comparable with the established profile of G in advanced FL. Clinical trial information: NCT03817853. [Table: see text]

9029 Objectives: Evaluate the safety and efficacy of CNTO 95, a human anti-αv integrin monoclonal antibody, when administered alone or in combination with dacarbazine (DTIC). Methods: Patients with Stage IV metastatic melanoma were randomized 1:1:1:1 to receive 5 or 10mg/kg CNTO 95 alone, or DTIC (1000mg/m2) + either 10mg/kg CNTO 95 or placebo administered intravenously once every 3 weeks for 8 cycles in the absence of disease progression or unacceptable toxicity. DTIC arms were blinded; single-agent arms were open-label. The primary endpoint was progression free survival (PFS); secondary endpoints included partial response (PR), complete response (CR), stable disease (SD) and overall survival (OS). Major safety endpoints included the incidence of adverse events (AEs) and serious AEs (SAEs). Results: Patients were randomized to receive 5mg/kg CNTO 95 (n=32), 10mg/kg CNTO 95 (n=33), CNTO 95+DTIC (n=32), or placebo+DTIC (n=32). Baseline demographics were similar across groups. The median PFS for CNTO 95+DTIC was 75 days, placebo+DTIC was 54 days and both CNTO 95 alone arms were 42 days. Six patients achieved PR (2–10mg/kg CNTO 95, 1-CNTO 95+DTIC, 3-placebo+DTIC); one patient achieved CR (CNTO 95+DTIC). A higher proportion (43.3%) of patients achieved SD ≥ 12 wks in the CNTO 95+DTIC group compared with the other 3 groups (<20.0%). The median survival was 11.0 months for the patients in the CNTO 95+DTIC arm, 9.8 months and 14.9 months for the 5mg/kg and 10mg/kg arms, and 8.0 months for those in the DTIC control arm. The most common AEs were headache, nausea, fatigue, pyrexia, vomiting and transient uveitic reactions. Three patients (1–5mg/kg, 2-CNTO 95+DTIC) discontinued treatment due to AEs. A higher proportion of patients experienced SAEs in the placebo+DTIC group (29.0%) than in the 5mg/kg (12.9%), 10mg/kg (16.2%) or CNTO 95+DTIC (18.8%) groups. Conclusions: CNTO 95 alone or combined with DTIC was generally well tolerated. In patients with Stage IV metastatic melanoma, a trend toward improvement in PFS, OS and disease control was demonstrated with CNTO 95+DTIC. Centocor, Centocor Research and Development, Inc.

642 Background: An overall survival (OS) benefit in WT KRAS exon 2 mCRC was not seen with pmab monotherapy in study 20020408 possibly due to crossover of patients (pts) in the BSC arm. Retrospective analyses have indicated that other KRAS and NRAS mutations beyond KRAS exon 2 are predictive of anti-EGFR tx effects. Study 20100007 assesses the OS benefit of pmab in chemorefractory WT KRAS exon 2 mCRC and is the first phase 3 trial to prospectively evaluate pmab tx effects in WT RAS (exons 2, 3, and 4 of KRAS and NRAS) mCRC. Methods: Anti-EGFR naive pts were randomized 1:1 to receive pmab (6 mg/kg Q2W) + BSC or BSC. KRAS exon 2 and RAS mutation status of tumors were determined centrally. The primary endpoint was OS in WT KRAS exon 2 mCRC. Secondary endpoints were OS in WT RAS mCRC and progression-free survival (PFS), objective response rate (ORR), and safety in both WT KRAS exon 2 and WT RAS groups. Crossover was not permitted. Results: 377 pts with WT KRAS exon 2 mCRC were enrolled. RAS ascertainment rate was 86%. OS was significantly improved with pmab + BSC vs BSC in both WT KRAS exon 2 (HR=0.73, 95% CI=0.57-0.93, P=0.0096) and WT RAS (HR=0.70, 95% CI=0.53-0.93, P=0.0135) mCRC (results in table). Pts with mutant RAS mCRC did not benefit from pmab tx (OS HR=0.99, 95% CI=0.49-2.00). No new safety signals were seen. Conclusions: Pmabsignificantly improved OS in chemorefractory WT KRAS exon 2 mCRC. The tx effects in OS and PFS were more pronounced in those with WT RAS mCRC, further substantiating the importance of RAS testing at diagnosis to best inform the use of pmab to treat mCRC.

102 Background: This phase II study aimed to investigate the safety and efficacy of XP compared to SP in the first-line treatment of HER2 negative AGC. Methods: Patients were randomly assigned to receive either SP (S-1 at 40–60 mg twice daily for 21 days plus cisplatin at 60 mg/ m2 on day 8, every 5 weeks) or XP (capecitabine 1,000 mg/m2 twice daily for 14 days plus cisplatin 80 mg/m2 on day 1, every 3 weeks). Primary endpoint was response rate (RR), and secondary endpoints were progression-free survival (PFS), overall survival (OS), time to treatment failure (TTF), and adverse events. Results: 84 eligible patients were randomly assigned to receive SP ( N = 41) or XP ( N = 43). No statistical difference was observed in overall RR between the SP and XP groups [51.2% (95% CI, 35.1% to 67.1%) vs. 53.5% (95% CI, 37.7% to 68.8%), P = 1.000]. Despite not significant, however, SP vs. XP showed a trend toward better PFS [median, 5.9 months vs. 4.1 months; hazard ratio (HR), 0.763; 95% CI, 0.462 to 1.259; P = .284] and OS (median, 13.5 months vs. 10.0 months; HR, 0.776; 95% CI, 0.485 to 1.244; P = .290). This trend in the SP vs. XP comparison was more pronounced in TTF (median, 4.5 months vs. 3.1 months; HR, 0.651; 95% CI, 0.421 to 1.006; P = .052). Common grade 3 to 4 hematological toxicities were neutropenia and anemia (SP group, 23% and 23%; XP group, 35% and 28%). Grade 3-4 anorexia and hyponatremia were more frequently seen in the XP group (31% and 16%) compared to the SP group (13% and 5%). Treatment-related deaths occurred in one patient (2.3%) in the XP group. Conclusions: XP failed to demonstrate the superior efficacy over SP. Higher incidence of severe toxicities by XP suggests SP as the standard 1st line chemotherapy for HER2 negative AGC in Japan. Clinical trial information: UMIN000006755.

PD-1 blockade enhances the function of anti-tumor T-cells and antibody-dependent cell-mediated cytotoxicity (ADCC) of NK cells. In a single-center, open-label, phase 2 trial, we tested the combination of pembrolizumab, an anti-PD-1 monoclonal antibody and rituximab, an anti-CD20 monoclonal antibody that induces ADCC, in 30 follicular lymphoma (FL) patients with rituximab-sensitive disease who relapsed after ≥1 prior therapy. Pembrolizumab was administered at 200mg IV every 3 weeks for up to 16 cycles and rituximab was given at 375mg/m2 IV weekly for 4 weeks in cycle 1 only. The most common grade 3/4 adverse events (AE) were liver enzyme abnormalities (3%), diarrhea (3%), nausea (3%), aseptic meningitis (3%) and pancreatitis (3%). Low-grade immune-related AEs were reported for 80% of patients, including diarrhea (43%), liver enzyme abnormalities (33%), thyroid dysfunction (27%), and rash (23%). Grade 3 or 4 immune related AEs occurred in 13% of patients. Treatment-related AEs led to discontinuation in 6 (20%) patients. Overall response rate (primary endpoint) was 67% and complete response rate was 50%. Median progression-free survival (PFS) was 12.6 months (95% CI, 8.2-27.6 months), the 3-year overall survival rate was 97%, and 23% of patients were in remission at a median follow up of 35 months. Presence of a high CD8+ T-effector score at baseline in the tumor was associated with induction of a complete response and improved PFS. In this single arm, phase 2 study, the combination of pembrolizumab and rituximab demonstrates favorable efficacy and safety profile in relapsed FL. This trial is registered at www.clinicaltrials.gov: NCT02446457.

Abstract Abstract 3657 Background: Bendamustine and rituximab is proving to be a superior first-line option in the treatment of follicular lymphoma. 90Y-ibritumomab tiuxetan is an effective consolidation strategy after chemotherapy induction in patients with follicular lymphoma, but has never been sequentially combined with bendamustine. In this prospective, single-arm, open-label, multicenter phase II trial (Fol-BRITE), we aim to assess the response rate and safety of a short induction course of bendamustine and rituximab (B-R) for 4 cycles followed by consolidation with 90Y-ibritumumab tiuxetan (90Y-IT) for chemotherapy-naïve patients with follicular lymphoma. Methods: Subjects greater than the age of 18 with chemotherapy-naïve follicular lymphoma (grade 1–2 and 3a) requiring treatment are eligible for this study. Treatment consists of an initial dose of rituximab 375mg/m2, and then one week later, bendamustine 90mg/m2 on days 1 and 2, and rituximab 375mg/m2 on day 1 of a 28-day cycle. B-R is given for a total of 4 cycles. Patients are eligible for consolidation with 90Y-IT if they obtain at least a partial response (PR) after induction, with a platelet count over 150,000/mm3, and granulocyte counts 1,500/mm3 and a bone marrow infiltration of <25%. The primary endpoint of this study is the determination of the complete response (CR) rate after sequential therapy with B-R followed by 90Y-IT. Secondary endpoints are overall response (OR=CR+PR) rate after a short course of B-R (4 cycles) and conversion rate from PR after B-R to CR after 90Y-IT. Secondary endpoints also include progression-free survival and safety. An optimal Simon two-stage design is incorporated to allow an early futility look for complete responses. Results: Nineteen patients have started treatment in this study to date, 13 have completed B-R and 7 have received 90Y-IT. Response rates after 4 cycles of B-R: Thirteen patients have completed 4 cycles of B-R and 13 are evaluable for response. Seven of 13 evaluable patients have had a CR (53.8%) and 5 of 13 patients have had a PR (38.5%) after 4 cycles of B-R for an OR rate of 92.3%. Response rates after B-R followed by 90Y-IT: Seven of 13 B-R-treated patients have received 90Y-IT and are evaluable for the primary endpoint of complete response. Of the 13 B-R treated patients, one patient in CR was unable to receive 90Y-IT due to thrombocytopenia, and one other patient was not eligible to receive 90Y-IT due to achievement of stable disease only. Six of the 7 evaluable patients are in CR (85.7%) and one patient remains in a PR (14.3%) after consolidation with 90Y-IT. Of the 3 subjects who attained a PR after B-R, 2 (66.7%) converted to a CR after 90Y-IT, with one late conversion 16 months after 90Y-IT. Hematologic toxicities after B-R included grade 4 neutropenia (1), grade 3–4 lymphopenia (3), and no grade 3–4 thrombocytopenia, out of 13 patients evaluable. Hematologic toxicities after 90Y-IT were acceptable, including grade 3–4 neutropenia (6), grade 3–4 lymphopenia (5), and grade 3–4 thrombocytopenia (4), out of 7 patients evaluable for toxicity. There have been no incidences of neutropenic fever. All patients have recovered their blood counts 7 to 12 weeks after Y90-IT. One out of 19 patients treated in this study has developed chronic myelogenous leukemia, occurring 11 months after treatment with Y90-IT. Conclusions: In this early pre-planned analysis of the first-stage of an optimal Simon two-stage design, we report this combination of therapy is both effective and safe. The CR rate of patients completing all study therapy is 85.7%, and well exceeds the limits required to continue this trial with an accrual goal of 39 subjects. Sequential treatment with B-R followed by Y90-IT is a promising option for the treatment of follicular lymphoma.

Abstract BACKGROUND New treatment modalities are needed for recurrent glioblastoma (rGBM). Selinexor is a novel, oral selective inhibitor of nuclear export which forces nuclear retention of tumor suppressor proteins including p53 and p27, leading to apoptosis. We previously reported interim results showing tolerability, preliminary efficacy, and blood-brain barrier penetration in a surgical cohort (N=8). We now report updated results following completion of accrual to non-surgical cohorts (N=68). MATERIALS AND METHODS This is an open-label, multicenter, phase 2 study of selinexor monotherapy. Patients (pts) not undergoing surgery for measurable rGBM per response assessment neuro-oncology criteria (RANO) were enrolled in one of 3 arms encompassing different dosing schedules of selinexor (50 mg/m2 [~ 85 mg] BIW, 60 mg BIW, and 80 mg QW). Treatment was continuous, although cycles were defined as 28 days and response was assessed every other cycle by MRI. Prior treatment with radiotherapy and temozolomide was required and prior bevacizumab was exclusionary. The primary endpoint was 6-month progression free survival (6mPFS) rate, calculated by the Kaplan-Meier method. RESULTS 76 pts were enrolled; 24, 14 and 30 pts on doses of ~85 mg BIW, 60 mg BIW, and 80 mg QW, respectively. Median age was 56 years (range 21–78). Median number of prior treatments was 2 (range 1–7) At the end of the 6 cycles, 30.2% pts on 80 mg QW were free from progression. The 6mPFS rate on 80 mg QW was 18.9%. Best RANO-defined responses (assessed locally) among 26 evaluable pts on 80 mg QW included 1 complete response, 2 partial responses, 7 stable disease, and 16 with progressive disease. Complete and partial responses were durable: the complete and a partial responder remain on selinexor for 393 and 1093 days respectively, as of the cut-off date. Median duration of response was 10.8 months. The most common related adverse events (all grades) in pts on ~85 mg BIW/60 mg BIW/80 mg QW were nausea (42%/64%/63%), leukopenia (38%/7%/43%), fatigue (71%/71%/47%), neutropenia (29%/14%/33%), decreased appetite (46%/71%/27%), and thrombocytopenia (67%/29%/23%). CONCLUSION Selinexor demonstrated efficacy, with durable responses and disease stabilization in rGBM. Based on the favorable efficacy and safety profile, selinexor at a dose of 80 mg QW is recommended for further development in rGBM.

BackgroundRecurrent or metastatic cervical cancer patients who progressed after standard therapy have limited treatment options and poor prognosis with a 1-year survival rate ranging between 15% and 20%. This study evaluates the efficacy and safety of toripalimab plus chemoradiotherapy in patients with recurrent or metastatic cervical cancer (Clinical trial ID: ChiCTR2000029068)MethodsIn this open-label, single-arm, phase 2 study conducted at four radiotherapy centers in East China, eligible patients were confirmed by pathology and/or imaging for recurrent or metastatic cervical cancer. According to the first-line therapies for cervical cancer recommended by NCCN guidelines, all patients were received paclitaxel plus cisplatin regimen, with or without bevacizumab, combined with radiotherapy. After seven fractions radiotherapy at the recurrent or metastatic regions, 240 mg toripalimab every three weeks for six cycles or more were given in combination.ResultsBetween Jan 14th, 2020, and May 1st, 2021, 24 patients were enrolled. All patients were staged at the first visit, as seven patients were with FIGO (2018) stage I, 10 with stage II, 2 with stage III, 1 with stage IV, and 2 with unclear stage. Of 24 included patients, 22 (91.67%) had squamous cervical cancer. The median age was 55 (range, 33–72) years. As of May 31, 2021, median follow-up time was 8.5 months [95% CI: 2.3–10.1]. 14 (58.3%) of 24 patients who achieved an objective response, including 10 (41.7%) complete response (CR) and 4 (16.7%) partial response (PR). The median duration of response was not reached and 7 (29.1%) patients continued toripalimab treatment after the previous 6-cycle immunotherapy. The disease control rate was 75% (18/24). Median progression-free survival (PFS) was 8.61 months (95% CI: 4.14–not reached). For subgroup analysis, the median PFS was significantly prolonged in the CR/PR group compared with that in the SD/PD group [not reached (95% CI: 6.21–not reached) versus 5.5 months (95% CI: 2.69–6.870), P = 0.023]. There was no significant difference in the median PFS between patients who previously received radiotherapy (8.61 months) and those who didn’t (6.87 months) (P = 0.641). 8 (33.3%) patients had grade 3–4 treatment-related adverse events (TRAEs). The most common grade 3-4 TRAEs were myelosuppression (29.2%), hypertriglyceridemia (8.3%), hypoalbuminemia (4.2%), pneumonia (4.2%), and hypercholesterolemia (4.2%).ConclusionsToripalimab plus chemoradiotherapy showed promising antitumor activity and tolerable toxicities in patients with recurrent or metastatic cervical cancer.

354 Background: Patients (pts) with mUC who progress after platinum (PLT)-based chemotherapy and immune checkpoint inhibitor (CPI) therapy have poor outcomes and limited treatment options. Sacituzumab govitecan (SG) is a novel antibody-drug conjugate. It consists of a monoclonal antibody targeting Trop-2, an epithelial cell surface antigen overexpressed in UC, conjugated to the active metabolite of irinotecan (SN38). Methods: We performed a phase I/II basket study in pts with advanced solid tumors receiving intravenous SG administered on day 1 and 8 of 21-day cycles, until progression or unacceptable toxicity. CT/MRI scans were obtained at 8-week intervals for response assessment. We evaluated pts with mUC who progressed after ≥1 prior systemic therapy and were treated with SG at the 10 mg/kg dose level. Endpoints included safety, objective response rate (ORR) by RECIST 1.1, clinical benefit rate (CBR; complete response [CR], partial response [PR], or else SD ≥6-mo), and Kaplan-Meier estimated duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Results: 45 pts (41M/4F; median age 67, range 49-90; ECOG 0/1: 31%/69%) received a median of 2 (range: 1-6) prior treatment lines, including PLT-based chemotherapy (95%) and CPI (38%). 33 had visceral metastases involving liver (n=15), lung (n=27), and other organs (n=5). The ORR was 31% (14/45), with 2 CR and 12 PR. In pts with visceral involvement, the ORR was 27% (9/33). The ORR in CPI-treated pts was 23% (4/17). The median DOR was 12.6 mo (2 pts continuing >2 y), and the CBR was 47% (21/45). Median PFS and OS were 7.3 mo and 18.9 mo, respectively. The AE profile was consistent with prior reports. Grade ≥3 AEs in ≥5% of pts were neutropenia/neutrophil count decreased (38%), anemia (11%), hypophosphatemia (11%), diarrhea (9%), fatigue (9%), and febrile neutropenia (7%). Conclusions: SG demonstrated clinical activity in pts with relapsed/refractory mUC, including CPI-treated pts and pts with visceral disease. A single-arm, open-label, global phase 2 trial is underway to evaluate antitumor activity and safety of SG in advanced UC.(TROPHY-U-01; NCT03547973). Clinical trial information: NCT03547973.

AbstractWe evaluated the triplet regimen obinutuzumab-atezolizumab-lenalidomide (G-atezo-len) for patients with relapsed/refractory (R/R) follicular lymphoma (FL) in an open-label, multicenter phase Ib/II study (BO29562; NCT02631577). An initial 3 + 3 dose‐escalation phase to define the recommended phase II dose of lenalidomide was followed by an expansion phase with G-atezo-len induction and maintenance. At final analysis, 38 patients (lenalidomide 15 mg, n = 4; 20 mg, n = 34) had completed the trial. Complete response rate for the efficacy population (lenalidomide 20 mg, n = 32) at end-of-induction was 71.9% (66.7% in double‐refractory patients [refractory to rituximab and alkylator] [n = 12]; 50.0% in patients with progressive disease within 24 months of first-line therapy [n = 12]). The 36-month progression-free survival rate was 68.4%. All treated patients had ≥1 adverse event (AE; grade 3–5 AE, 32 patients [84%]; serious AE, 18 patients [47%]; AEs leading to discontinuation of any study drug, 11 patients [29%]). There were 2 fatal AEs (1 merkel carcinoma, 1 sarcomatoid carcinoma; both unrelated to any study drug). The G‐atezo-len regimen is effective and tolerable in patients with R/R FL. AEs were consistent with the known safety profile of the individual drugs.

707 Background: VEGF promotes tumor angiogenesis and metastasis. Z blocks the activity of VEGF-A/-B, and placental growth factor and was shown in the VELOUR phase III study (NCT00561470) outside of Japan to significantly improve overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) in mCRC pts as a second-line treatment given with FOLFIRI. Goals of the current open-label, multicenter phase II study were to assess the efficacy and safety of Z + FOLFIRI in a post-oxaliplatin setting in mCRC pts in Japan. Methods: Pts received Z (4 mg/kg) + FOLFIRI (400 mg/m2 bolus 5-fluorouracil [FU]; 2400 mg/m2 continuous infusion 5-FU; 200 mg/m2 levofolinate; 180 mg/m2 irinotecan) every 2 weeks until progression, unacceptable toxicity, or study withdrawal. Primary endpoint: ORR (required 60 pts in order to obtain a 95% CI width of 16–20%, assuming an ORR of 10–20%). Secondary endpoints: PFS, OS, and safety. Tumors were assessed by independent reviewers every 6 ± 1 weeks until progression. Results: Study enrolled 62 pts; 50 pts (83.3%) had received prior bevacizumab. Of 60 pts evaluable for response, 5 had a partial response and none had a complete response, resulting in an ORR of 8.3% (95% CI: 1.3–15.3%). The median PFS was 5.42 months (95% CI: 4.140–6.702), and the median OS was 15.59 months (range 11.20–19.81). Forty-one pts (66.1%) died due to progression; none died due to study treatment. Pts underwent a median of 8 treatment cycles (range 1–31) lasting a median of 21.8 weeks (range 2–73). The median relative dose intensity was 0.99 (range 0.2–1.0) for Z, 0.87 (range 0.4–1.0) for irinotecan, and 0.96 (range 0.7–1.0) for 5-FU. All pts had ≥1 treatment emergent adverse event (TEAE; see table). Conclusions: The ORR was 8.3% (95% CI: 1.3–15.3%), and the median OS was 15.59 months. The safety profile was consistent with that reported previously. Registered as NCT01882868. Clinical trial information: NCT01882868. [Table: see text]
