Platinum Based Chemotherapy

BackgroundThere are limited treatment options for patients with metastatic or recurrent cervical cancer. Platinum-based chemotherapy plus the anti-vascular endothelial growth factor antibody bevacizumab remains the mainstay of advanced treatment. Pembrolizumab is Food and Drug Agency approved for programmed death ligand 1 (PD-L1) positive cervical cancer with a modest response rate. This is the first study to report the efficacy and safety of the PD-L1 antibody atezolizumab in combination with bevacizumab in advanced cervical cancer.MethodsWe report the results from a phase II, open-label, multicenter study (NCT02921269). Patients with advanced cervical cancer were treated with bevacizumab 15 mg/kg intravenous every 3 weeks and atezolizumab 1200 mg intravenous every 3 weeks. The primary objective was to measure the objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety.ResultsIn the total evaluable population (n=10), zero patients achieved an objective response as assessed by Response Evaluation Criteria In Solid Tumors (RECIST) V.1.1, resulting in a confirmed ORR of 0%. Of note, there were two patients who achieved an unconfirmed PR. The DCR by RECIST V.1.1 was 60% (0% complete response, 0% partial response, 60% stable disease). Median PFS was 2.9 months (95% CI, 1.8 to 6) and median OS was 8.9 months (95% CI, 3.4 to 21.9). Safety results were generally consistent with the known safety profile of both drugs, notably with two high-grade neurologic events.ConclusionsThe combination of bevacizumab and atezolizumab did not meet the predefined efficacy endpoint, as addition of bevacizumab to PD-L1 blockade did not appear to enhance the ORR in cervical cancer.

TPS5596 Background: There is no consistent recommendation for management of metastatic cervical cancer beyond first line therapy with chemotherapy and bevacizumab. Pembrolizumab is now approved for PD-L1 positive or MSI-H/dMMR metastatic or recurrent cervical cancer. Numerous pre-clinical studies have provided evidence to combine radiation therapy with immune checkpoint inhibition to improve response rates. The evidence is strongest for short course, hypofractionated radiation regimens. We hypothesize treatment with atezolizumab with hypofractionated radiation therapy will improve objective response rate (ORR) compared with atezolizumab alone in patients with recurrent, persistent, or metastatic cervical cancer. Methods: The study is designed as a prospective, single arm, nonrandomized, open-label, phase II trial of stereotactic body radiation therapy (SBRT) with 24 Gy in 3 fractions to patients with ≥ 2 metastatic sites followed 1 week later by atezolizumab (1200 mg IV every 3 weeks) for patients with recurrent, persistent, or metastatic cervical cancer. Dose reductions will not be allowed. The primary objective of the study is to evaluate the ORR by Immune-Modified Response Evaluation Criteria in Solid Tumors (irRECIST) criteria following SBRT and atezolizumab. Secondary endpoints include progression free survival, overall survival, local control, and adverse events. Correlative aims include assessing blood and tissue biomarkers (i.e. PD-L1, mutation burden, TCR repertoire etc.) for association with clinical benefit. A total of 26 patients will be enrolled. An interim analysis will be performed to assess efficacy after 13 patients become evaluable.This study is open with 2 patients enrolled at the time of submission. Clinical trial information: NCT03614949.

PURPOSE Targeted therapies against non–small-cell lung cancer (NSCLC) harboring HER2 mutations remain an unmet need. In this study, we assessed the efficacy and safety of pyrotinib in patients with HER2-mutant advanced NSCLC in a prospective, multicenter, open-label, single-arm, phase II study. PATIENTS AND METHODS Patients with stage IIIB or IV HER2-mutant lung adenocarcinoma who were previously treated with platinum-based chemotherapy were enrolled to receive pyrotinib at a dose of 400 mg/d for 21-day cycles. The primary end point was objective response rate per independent review committee (IRC). RESULTS Between October 20, 2016, and December 10, 2018, 60 patients received pyrotinib monotherapy. At baseline, 58 (96.7%) were stage IV, and 25 (41.7%) received at least 2 lines of prior chemotherapy. As of data cutoff on June 20, 2019, IRC-assessed objective response rate was 30.0% (95% CI, 18.8% to 43.2%). All subgroups of patients with different HER2 mutation types showed a favorable objective response rate. The objective response rates were similar between patients with and without brain metastases (25.0% v 31.3%). The median duration of response was 6.9 months (95% CI, 4.9 to 11.1 months). The median progression-free survival was 6.9 months (95% CI, 5.5 to 8.3 months) per IRC. The median overall survival was 14.4 months (95% CI, 12.3 to 21.3 months). Treatment-related adverse events of grade 3 or 4 occurred in 28.3% of patients, with the most common being diarrhea (20.0%; all grade 3). No treatment-related deaths were reported. CONCLUSION Pyrotinib showed promising antitumor activity and an acceptable safety profile in chemotherapy-treated patients with HER2-mutant NSCLC.

ObjectivesWe conducted a phase II study to investigate the efficacy and toxicities of irinotecan plus oral S-1 in patients with advanced or recurrent uterine cervical cancer.MethodsPatients with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy were enrolled. Irinotecan (150 mg/m2) was administered intravenously over the course of 90 min on day 1, and S-1 (80 mg/m2) was given orally in two divided doses from days 1 to 14 of a 21 day cycle. The primary endpoint of this phase II study was response rate. Secondary endpoints included safety, progression free survival, and overall survival.ResultsA total of 19 patients were enrolled and treated. The response rate was 29.4%. Grade 3–4 hematologic toxicities were observed in three patients (15.7%). The only grade 3–4 non-hematologic toxicity observed was grade 3 diarrhea. The median progression free survival and overall survival were 3 months and 9 months, respectively.ConclusionS-1 plus irinotecan in a 3 weekly setting is safe and active in women with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy. Future corroborative clinical studies are warranted.

4051 Background: Afatinib, an irreversible pan-ErbB kinase inhibitor showed anti-tumor activity against esophageal cancer in phase I trial. In this multicenter, open-label, single arm phase II study, we aimed to evaluate the activity and safety of afatinib in R/M ESCC. Methods: Patients (pts) who had ECOG PS 0-2 and had progressed on platinum-based chemotherapy for R/M ESCC were enrolled. Pts were treated with afatinib 40mg/day until disease progression, unacceptable toxicity, or patient’s refusal. Primary endpoint was objective response rate (ORR) per RECIST 1.1. The estimated sample size was 49, using a two-stage minimax design to evaluate incremental response rate from 5 to 15%. Secondary endpoints included progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and safety profile. Additionally, we try to identify biomarker to predict efficacy of afatinib with target capture sequencing and gene expression profile as exploratory endpoints. Results: In a total of 49 enrolled pts (median age 60; range 44 -84), ORR and DCR were 14.3 % and 73.3%, respectively. With a median follow-up of 6.6 months, median PFS and OS was 3.4 months (95% CI 2.2-4.6) and 6.6 months (95% CI 5.2-8.0). Median treatment duration and duration of response were 2.8 months (range, 0.4-15.3) and 7.1 months (range, 2.5-13.9), respectively. Dose reduction and interruption occurred in 19 (38.8%) and 15 (30.6 %) pts. Treatment-related adverse events (TRAE) occurred in 33 pts (67.3%) with most common TRAEs being diarrhea (n=22, 44.9%) and acneiform rash (n=12, 24.5%). G3-4 TRAEs were rare, occurring in 7 pts (14.3 %). Conclusions: Afatinib demonstrated modest efficacy with manageable toxicity in platinum-resistant R/M ESCC patients. Given the modest response rate, identification of predictive biomarkers is essential for further clinical investigation of afatinib in R/M ESCC. Those biomarkers are being analyzed and will be presented in the conference (NCT02353936). Clinical trial information: NCT02353936. [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.

5524 Background: It is difficult for patients with recurrent advanced cervical cancer to obtain clinical benefits after the failure of standard chemotherapy. However, antiangiogenic therapy combined with immune checkpoint inhibitors have become a promising strategy for advanced cervical cancer. Anlotinib is a novel multi-target tyrosine kinase inhibitor, inhibiting tumour angiogenesis and proliferative signalling. Sintilimab is a fully humanized, high-affinity monoclonal antibody against programmed cell death-1 (PD-1). This phase II, single-arm study (ChiCTR1900023015) aims to evaluate the efficacy and safety of anlotinib plus sintilimab in patients with recurrent advanced cervical cancer. Methods: Patients who have received at least once platinum-based chemotherapy, histopathologically confirmed recurrent advanced cervical cancer (including squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma), more than 1% PD-L1 expression, ECOG 0-1 were considered eligible for enrollment. Anlotinib was taken orally (10mg mg qd, d1-14, 21 days per cycle), and sintilimab was administered intravenously (200mg once every 3 weeks). The treatment was continued until disease progression, death or intolerant toxicity. The primary endpoint was objective response rate (ORR) and the secondary endpoints included disease control rate (DCR), progression free survival (PFS), overall survival (OS) and safety. Results: Between September 2019 and February 2021, 42 patients with a median age of 52 years (range:47-58), FIGO histopathological stage I (11.9%), II (31.0%), III (33.3%), IV (9.5%) and undiagnosed (14.3%) were enrolled. 39 of these patients were evaluable. In the efficacy-evaluable population (n = 39), the therapeutic evaluation showed that 2 and 20 patients achieved complete response and partial response respectively, yielding the ORR of 56.4% (22/39, 95% CI:40.2 to 71.5). The DCR was 94.9% (37/39, 95% CI:80.7 to 98.8). The median response time was 1.6 months. The median PFS was not reached. The most common adverse events (AEs) were grade 1 or 2, which included hypothyroidism (33.3%), hypertension (23.8%), AST (21.4%), diarrhea (19.0%), ALT (16.7%), hand-foot syndrome(14.3%), hypertriglyceridemia (14.3%) and anemia (11.9%). The grade 3 AEs were hypertension (4.8%), hyponatremia (4.8%), immune pneumonia (2.4%) and immune myocarditis (2.4%). No higher AEs and treatment-related death were observed. Conclusions: Anlotinib plus sintilimab showed a promising efficacy with a favorable toxicity profile for patients with recurrent advanced cervical cancer. We will report more data in the future. Clinical trial information: ChiCTR1900023015.

Background Adding bevacizumab to chemotherapy for recurrent, persistent or metastatic cervical cancer significantly improved overall survival (primary endpoint), progression-free survival and overall response rate in the randomized Phase III GOG-0240 trial. However, data for bevacizumab-containing therapy are scarce in Japanese patients with advanced cervical cancer. Methods The primary objective of the single-arm multicenter Phase II JO29569 study was to evaluate the tolerability of paclitaxel (135 mg/m2 over 24 h or 175 mg/m2 over 3 h), cisplatin (50 mg/m2) and bevacizumab (15 mg/kg), administered every 3 weeks until disease progression or unacceptable toxicity in Japanese patients with stage IVB, persistent or recurrent cervical cancer. Results The seven treated patients received a median of nine (range 7–12) bevacizumab cycles and six (range 4–12) chemotherapy cycles. None of the predefined adverse events occurred during the tolerability evaluation period. The most common all-grade adverse events were alopecia, hypertension, decreased appetite, nausea and peripheral sensory neuropathy. There were no cases of fistula. The most common grade ≥3 adverse events were hypertension, neutrophil count decreased and neutropenia. Only one patient experienced febrile neutropenia. The overall response rate was 86% (95% confidence interval, 42–100%), including a complete response in one patient. At data cutoff, disease had progressed in one patient; bevacizumab therapy was ongoing in the remaining six. Conclusions According to the specified primary objective, a regimen of cisplatin, paclitaxel and bevacizumab was tolerable in Japanese patients and demonstrated encouraging activity in this small single-arm study. Further study is warranted to confirm the safety and effectiveness of bevacizumab in Japanese patients with cervical cancer.

e16201 Background: Limited systemic treatment options are available for progressive well-differentiated neuroendocrine tumors (NET), also called carcinoid tumors. Given emerging evidence for immunotherapy response in high grade NET including small cell lung cancer, we sought to determine the efficacy of combination immunotherapy with ipilimumab and nivolumab in patients with advanced, progressive, well-differentiated NET in an open label phase II clinical trial. Methods: Eligible patients had well-differentiated, nonfunctional NET of lung, pancreas, or GI origin that had progressed within the past 12 months after at least one line of prior therapy. Patients received nivolumab 240 mg every 2 weeks and ipilimumab 1mg/kg every 6 weeks for up to 2 years. Primary endpoint was objective response rate (ORR) by RECIST v1.1. Using a Simon’s 2-stage design, the study planned to accrue up to 56 patients. Based on published response rates to everolimus of 5%, we hypothesized that this regimen would be considered promising if the true ORR is > 15%. Results: Nine patients were enrolled prior to study closure due to funding, including 6 patients with NET of lung origin, 2 pancreatic, and 1 small bowel (Table). Median age was 71 years. All patients had distant metastatic disease at enrollment, with an average of 2 prior lines of therapy. Four of 9 patients achieved the primary endpoint of confirmed objective response, all of whom have ongoing response with a median duration of 15.4 months. Five of 9 patients, including all 4 responders, experienced immune-related toxicity requiring treatment modification or discontinuation. The trial did not accrue the target of 56 patients, however, objective response in 4 of 9 patients (ORR 44.4%, 90% CI: 16.9-74.9%) excluded the response rate target (15%). Conclusions: The impressive ORR of 44% with a median duration of response exceeding 15 months in this small clinical trial warrants further study of combination CTLA-4 and PD-1 inhibition in previously treated well-differentiated NET. Our ongoing immunologic and genomic correlative analysis in responders and non-responders will help inform future study of immunotherapy in this patient population in need of new systemic therapy approaches. Clinical trial information: NCT03420521. [Table: see text]

TPS253 Background: GEC is the third leading cause of cancer mortality and the fifth most common malignancy worldwide. Fluoropyrimidine and platinum-based combinations are the most commonly used 1L treatment regimens. There are few standard treatment options after 1st line regimens. In the 3L+ GEC Keynote-059 trial, objective response rate (ORR) with Pembro was 15.5% in PD-L1(+) vs. 6.4% in PD-L1(-) tumors. While the responses were durable, the 6-months PFS (6-PFS) was only 14.1% and the median PFS was 2.0 mo. This highlights the remaining unmet need for the majority of patients who either are refractory or develop disease progression following treatment with PD-1 inhibitors in GEC. Cabo plus checkpoint inhibitors have shown clinical benefit in various cancers including hepatocellular, renal cell (RCC), urothelial and castration-resistant prostate cancers. In the CheckMate-9ER trial, Cabo+Nivolumab improved both OS and PFS vs sunitinib in 1L RCC. In patients with RCC who had progression on anti-PD1 inhibitor treatment, Cabo showed promising activity with an ORR of 33% and DCR of 79% (ESMO 2018, abstract 3793). Hypothesis: Based on preclinical and clinical observations, Cabo might contribute to overcoming primary or secondary resistance to PD-1 blockade in GEC. Methods: Prospective, open label, non-randomized phase 2 trial. Eligibility: Diagnosis of GEC, 2+ line of treatment including previous fluoropyrimidine/platinum, ECOG 0-2, adequate organ function, prior checkpoint inhibitor if tumor PD-L1 CPS≥10%. Treatment: Cabozantinib 40mg PO daily, Pembrolizumab 200 mg IV on day 1 of 21d cycle. Primary objective: Feasibility of the combination and estimate of efficacy. Primary endpoint:PFS-6. Secondary objectives: OS, ORR, adverse events. Total number of patients to be enrolled N = 27. Current enrollment (Sep 2020) N = 10. Statistics: If the PFS-6 is > 25%, the study would be regarded as positive, in which case it is planned to expand patient enrollment into a larger single arm phase 2 trial with additional sites to establish the efficacy of the regimen. Clinical trial information: NCT04164979.
