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.

11565 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of STS pts with CDK4 amplification treated with P are reported. Methods: Eligible pts had advanced STS, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received P at 125 mg orally once daily for 21 days, followed by 7 days off until disease progression. Pts matched to P had CDK4 amplification and no RB mutations. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 29 pts (66% male) with STS with CDK4 amplification were enrolled from July 2016 to Nov 2019. 1 pt was not evaluable and excluded from efficacy analyses. Demographics and outcomes are summarized in Table. One pt with partial response (PR) and 12 pts with SD16+ were observed for DC and objective response (OR) rates of 48% (95% CI: 31%, 62%) and 3.7% (95% CI: 0.1%, 19%), respectively, and the null DC rate of 15% was rejected (p<0.001). 9/13 pts with DC continued on treatment for >32 weeks. 14 pts had at least one grade 3-4 AE at least possibly related to P with the most common being low WBC/platelets. Other grade 3 AEs included increased alanine aminotransferase, anemia, and fatigue. Conclusions: Monotherapy P demonstrated anti-tumor activity in heavily pre-treated pts with STS with CDK4 amplification. Additional study is warranted to confirm the efficacy of P in pts with STS with CDK4 amplification. Clinical trial information: NCT02693535. [Table: see text]

108 Background: GT0918 is a 2nd generation of AR antagonist and capability to down-regulate AR level. This study is an open-label, randomized, multicenter, Ph II study to evaluate the safety and efficacy in patients with mCRPC, and to determine the optimal dose for Ph III study. Methods: Patients with historically confirmed mCRPC who progressed after/intolerant to/reluctant to receive Docetaxel and previously treated with abiraterone or enzalutamide were excluded. All the patients received up to 6 cycles or, unacceptable toxicity, or loss of clinical benefit as recommended by PCWG3. Primary endpoint was prostate-specific antigen (PSA) reduction from baseline. Secondary endpoints included time to PSA progression (TTPP), objective response rate (ORR), progression free survival (PFS), disease control rate (DCR) and safety profiles. Results: As of June 30, 2019, 108 treated with GT0918 at three dose levels: 100 mg (n =37), 200 mg (n = 35) and 300 mg (n = 36), the median age of patients was 70.0 years (range 63-77), 88% of patients had stage IV disease at the initial diagnosis and 69.4% had Gleason score ≥ 8. The median duration of disease was 2.88 years. All received prior endocrine therapy, 35.2% received prior chemotherapy, 29.6% received Docetaxel. The median PSA at baseline was 35.285ng/ml, PSA response rate (≥50 % reduction from baseline) was 41.9%. The median time to PSA progression was not reached. There was no significant difference among three arms. Of 19 evaluable patients with target lesions at baseline, the ORR was 15.8% (all were PR) assessed by IRC with RECIST v 1.1, with 20.0% (1/5), 22.2% (2/9), 0 (0/5) at 100, 200, 300 dose level, respectively. The DCR assessed by IRC was 78.9% (CR 0+PR15.8%+SD 63.2%). Of 26 evaluable patients with target lesions at baseline, the ORR was 19.2% assessed by investigators (CR 3.8%+PR 15.4%), with 11.1% (1/9), 20.0% (2/10), 28.6% (2/7) at 100, 200, 300 dose level, respectively. Overall, AEs were experienced by most of patients (94.4 %, n=102). AEs leading to drug interruption were reported in 13 patients (12.0%), 9 (8.3%)of them were suspected to be drug related. AEs leading to discontinuation were reported in 6 patients (5.6%), 3(2.8%) were possibly related to GT0918. 14 patients (13.0%) experienced Grade 3 and 4 AEs. 17 patients (15.7%)experienced SAE, 5(4.6%) of them were suspected to be related to study drug. Most of AEs were mild or moderate. The common suspected AE (≥10%) were asthenia (17.6%, n=19), anemia (14.8%, n=16), AST increased (14.8%, n=16), ALT increased (13.0%, n=14), decreased appetite (13.0%, N=14), white blood cell count decreased (12.0%, n=13), proteinuria (12.0%, n=13). Conclusions: GT0918 showed a manageable safety profile. This study provided preliminary anti-tumor activity in patients with mCRPC. 200mg/day is recommended dose for Ph III trial.

5504 Background: Treatment options for cervical, vaginal, and vulvar (GYN) cancers are limited after first-line therapy. Human papillomavirus (HPV) infection is associated with squamous cell carcinomas of the cervix (≥90%) and vulva/vagina (40–70%), and may elicit an immune reaction. Programmed death (PD)-1 and its major ligand PD-L1 are expressed in GYN cancers and inhibit immune responses. Nivolumab disrupts PD-1–mediated signaling, restoring antitumor immunity. Methods: In CheckMate 358 (NCT02488759), an ongoing multicohort study of 5 virus-associated cancers, PD-L1–unselected adults with R/M GYN cancers, ECOG PS 0–1, and ≤2 prior systemic therapies for R/M disease were eligible to receive nivolumab 240 mg every 2 weeks until progression or unacceptable toxicity. Primary endpoints were objective response rate (ORR) and safety; secondary endpoints were duration of response (DoR), progression-free survival (PFS), and overall survival (OS). Results: Of 24 treated patients (pts), 19 had cervical and 5 had vaginal or vulvar cancer; median age was 51 y. At a median follow-up of 31 wks (range: 6–38), ORR was 20.8% (Table), and disease control rate (ORR + SD) was 70.8%. All responses were in pts with cervical cancer (ORR, 26.3%) and were observed regardless of PD-L1 or HPV status or number of prior R/M therapies. Median PFS was 5.5 mo (95% CI: 3.5, NR); median OS was NR. Conclusions: Nivolumab demonstrated encouraging clinical activity in pts with cervical cancer and a manageable safety profile in virus-associated GYN cancers, supporting further evaluation in these pts. Updated clinical and biomarker data to be presented. Clinical trial information: NCT02488759. [Table: see text]

6043 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of HNC pts with CDKN2A loss or mutation treated with P are reported. Methods: Eligible pts had advanced HNC, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received P at 125 mg orally once daily for 21 days, followed by 7 days off until disease progression. Pts matched to P had CDKN2A loss or mutation and no RB mutations. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 28 pts (64% male) with HNC with CDKN2A loss (20 pts) or mutation (8 pts) were enrolled from June 2016 to Sept 2019. All were eligible for efficacy and toxicity. Demographics and outcomes are summarized in Table. No objective response (OR) and 10 pts with SD16+ (9 with CDKN2A loss, 1 with mutation) were observed for a DC rate of 37% (95% CI: 21%, 50%); the null DC rate of 15% was rejected (p=0.005). 14 pts had at least one grade 3-5 adverse or serious adverse event (AE/SAE) at least possibly related to P with the most common being low WBC/platelets. Other grade 3-4 AEs included anemia, fatigue, hypocalcemia, and syncope. There was one pt with grade 5 respiratory failure likely due to extensive lung metastases and aspiration but P-related pneumonitis could not be ruled out. Conclusions: Monotherapy P demonstrated modest anti-tumor activity and clinically significant AEs in heavily pre-treated pts with HNC with CDKN2A loss or mutation. Additional study is warranted to confirm the efficacy of P in pts with HNC with CDKN2A loss or mutation. Clinical trial information: NCT02693535. [Table: see text]

PURPOSE Camrelizumab is an antibody against programmed death protein 1. We assessed the activity and safety of camrelizumab plus apatinib, a tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, in patients with advanced cervical cancer. METHODS This multicenter, open-label, single-arm, phase II study enrolled patients with advanced cervical cancer who progressed after at least one line of systemic therapy. Patients received camrelizumab 200 mg every 2 weeks and apatinib 250 mg once per day. The primary end point was objective response rate (ORR) assessed by investigators per RECIST version 1.1. Key secondary end points were progression-free survival (PFS), overall survival (OS), duration of response, and safety. RESULTS Forty-five patients were enrolled and received treatment. Median age was 51.0 years (range, 33-67 years), and 57.8% of patients had previously received two or more lines of chemotherapy for recurrent or metastatic disease. Ten patients (22.2%) had received bevacizumab. Median follow-up was 11.3 months (range, 1.0-15.5 months). ORR was 55.6% (95% CI, 40.0% to 70.4%), with two complete and 23 partial responses. Median PFS was 8.8 months (95% CI, 5.6 months to not estimable). Median duration of response and median OS were not reached. Treatment-related grade 3 or 4 adverse events (AEs) occurred in 71.1% of patients, and the most common AEs were hypertension (24.4%), anemia (20.0%), and fatigue (15.6%). The most common potential immune-related AEs included grade 1-2 hypothyroidism (22.2%) and reactive cutaneous capillary endothelial proliferation (8.9%). CONCLUSION Camrelizumab plus apatinib had promising antitumor activity and manageable toxicities in patients with advanced cervical cancer. Larger randomized controlled trials are warranted to validate our findings.

4054 Background: Despite advances in the treatment of metastatic pancreatic cancer (PC), there is critical need to develop novel therapies.Median survival with combination chemotherapy is limited to less than one year and only the optimally conditioned patients can tolerate these therapies. Bavituximab (B) is a monoclonal antibody (mAB) directed againstphosphatidylserine (PS) that causes vascular shutdown and reactivation of the innate and adaptive immunity in animal models. Preclinical data in mouse PC models indicate that gemcitabine (G) increases PS exposure and the addition of a mAb targeting PS reduces tumor burden, visible liver metastases, microvessel density, and increases tumor macrophage infiltration compared to G alone (Beck et al. 2006). The purpose of this trial is to evaluate and compare the efficacy and safety of the combination of G+B vs. G alone as first line therapy in pts. with nonresectable Stage IV PC. Methods: Seventy patients were randomized (1:1) to receive G 1000 mg/m2 on days 1, 8, and 15 every 28Edays with or without weekly B 3mg/kg IV until disease progression or unacceptable toxicities. Key eligibility criteria were Stage IV PC, ECOG ≤2, measurable disease, age≥18 years, total bilirubin ≤1.5xULN, and adequate renal, hematologic, and hepatic function. The primary efficacy endpoint was overall survival (OS) and secondary endpoints included overall response rate (ORR) and progression free survival (PFS). Results: Of the 70 (G/G+B 34/36) patients randomized, 67 (G/G+B 33/34) received study treatment and 63 (G/G+B 31/32) were evaluable. No significant difference was seen in age, gender, race or ECOG. At analysis 87% deaths had been reported in G and 72% in G+B group. Median OS estimate is 5.2 months for G and 5.6 months for G+B. No difference between groups was observed in PFS (median 3.9 months for G and 3.7 months for G+B). ORR was 13% for G and 28% for G+B. Most AEs were grade 1-2 and typical of exposure to G. Conclusions: In this patient population with extensive disease burdens and limited treatment options, G+B was well tolerated and demonstrated moderate activity in tumor response and survival. Clinical trial information: NCT01272791.

6 Background: Patients (pts) with GC/GEC often present with A/M disease, which has a poor prognosis, with 1-year survival < 30%, and few treatment options. Nivolumab is a fully human anti-PD-1 IgG4 monoclonal antibody with a favorable safety profile and efficacy in melanoma, non–small-cell lung cancer, and renal cell carcinoma. The phase I/II, open-label CheckMate-032 study evaluated nivolumab ± ipilimumab in pts with solid tumors. Here, we report initial results for pts with GEC/GC receiving nivolumab monotherapy. Methods: Pts with A/M histologically confirmed GC/GEC, irrespective of PD-L1 status, were assigned to receive nivolumab alone (3 mg/kg IV Q2W) and treated until disease progression (PD) or intolerable toxicity. The primary endpoint was objective response rate (ORR); other endpoints included safety, progression-free survival, overall survival (OS), and biomarker status. Results: 59 pts were enrolled and treated with single-agent nivolumab. Median age was 60 y (range 29–80), and 83% of pts received ≥ 2 prior regimens. At database lock, 10 pts were on active treatment; 49 pts discontinued (PD, n = 40; unrelated adverse events, n = 4; treatment-related adverse events [TRAEs], n = 2; other, n = 3). Pts received a median of 4 doses (range 1–25). ORR was 12% (n = 7/58; 1 complete response, 6 partial responses); 12 pts (21%) had stable disease. Among responders, median duration of response was 7.1 mo (95% CI, 3.0–13.2). Median OS was 6.8 mo (95% CI, 3.3–12.4); 12-mo OS rate was 38% (95% CI, 23.2–52.7). 39% of tumor samples were PD-L1 positive ( ≥ 1% cutoff). ORRs in pts with PD-L1-positive and -negative tumors were 18% and 12%, respectively. TRAEs occurred in 66% of pts; most were Grade 1/2. Grade 3/4 TRAEs occurred in 14% of pts and included pneumonitis, fatigue, diarrhea, vomiting, hypothyroidism, and increased aspartate and alanine aminotransferase and alkaline phosphatase levels. No treatment-related deaths occurred. Conclusions: Nivolumab monotherapy was well tolerated and demonstrated encouraging antitumor activity in heavily pretreated pts with GC/GEC. Objective responses occurred in pts with PD-L1-positive and -negative tumors. Clinical trial information: NCT01928394.

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.

Background The purpose of this study was to study the effectiveness of gemcitabine and nab-paclitaxel combination as first-line chemotherapy regimen for the treatment of metastatic pancreatic cancer. There is scarcity of data regarding efficacy and toxicity profile of this combination in Indian population. Aims and Objectives The primary aim of this study was to assess efficacy of this regimen, for which evaluation done in terms of the objective response rate, progression-free survival (PFS), and overall survival. Safety data were also evaluated. Materials and Methods In this prospective study, gemcitabine plus nab-paclitaxel combination chemotherapy was given as first line in metastatic pancreatic carcinoma patients till progression or appearance of grade 3/4 toxicities with treatment. Results The study was performed in 30 patients comprising 18 (60%) males and 12 (40%) females. The median age was 60 years. Median number of cycles administered were six cycles per patient. Seventeen patients (56.67%) had a partial response and 0% had complete response. A total of seven (23.3%) patients progressed on chemotherapy and six (20%) had stable disease (SD). The disease control rate (responses and SD) was 76.7%. The median PFS was 5.75 months. There was no statistically significant difference in terms of response rates and baseline CA 19-9 levels. Most common toxicities were hematological toxicities with rates of grade 3/4 anemia and neutropenia of 20%. Among nonhematological toxicities, nausea (46.67%) and fatigue (30%) were the commonest. Conclusion Combination of gemcitabine and nab-paclitaxel is active and well tolerated in advanced pancreatic carcinoma. To the best of our knowledge, this is the first such study conducted in India.

5508 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of UC pts with ERBB2 or ERBB3 amplification , overexpression or mutation treated with P+T are reported. Methods: Eligible pts had advanced UC, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts matched to P+T had UC with ERBB2 or ERBB3 amplification or overexpression or a pre-specified ERBB2 mutation. Recommended dosing was P at an initial dose of 840 mg intravenously (IV) over 60 minutes (m), then 420 mg IV over 30-60 m every 3 weeks (wks), and T at an initial dose of 8 mg/kg IV over 90 m, then 6 mg/kg IV over 30-60 m every 3 wks until disease progression. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: Twenty-eight female pts were enrolled from August 2017 to November 2019; all pts were evaluable for efficacy and toxicity. Demographics and outcomes are summarized in Table. Twenty-two pts had tumors with ERBB2 amplification (21) or overexpression (1); 4 tumors had ERBB2 mutations; 1 tumor had ERBB3 amplification; 1 tumor had both an ERBB2 amplification and mutation. Two PR and 7 SD16+ were observed in pts with ERBB2 amplification, and 1 SD16+ was observed in a pt with ERBB2 V8421 mutation only (no amplification) for DC and objective response (OR) rates of 37% (95% CI, 21% to 50%) and 7.1% (95% CI, 0.8% to 24%), respectively. One pt experienced grade 3 muscle weakness at least possibly related to P+T. Conclusions: P+T demonstrated evidence of anti-tumor activity in heavily pre-treated UC pts with ERBB2 amplification or certain mutations. Additional study is warranted to confirm the efficacy of P+T in this pt population. Clinical trial information: NCT02693535. [Table: see text]
