420 Background: RX-3117 is an oral small molecule antimetabolite, cyclopentyl pyrimidyl nucleoside that is activated by cancer-enriched uridine cytidine kinase 2. Single agent RX-3117 has demonstrated efficacy in a phase III single agent clinical study of RX-3117 in met-PC and bladder cancer. RX-3117 in combination with nab-pac is being evaluated as first line treatment of met-PC cancer. Methods: This is a multicenter, open label phase I/II study (NCT03189914). Eligible subjects (aged ≥ 18 years) have histologically or radiologically proven met-PC with no prior therapies for metastatic disease, ECOG PS 0-1, and normal lab values. phase I identified the MTD dose that is being further evaluated in the phase II: RX-3117 (700 mg administered orally once-daily for 5 consecutive days with 2 days off per week) and nab-pac (125 mg/m2 administered once weekly) for 3 weeks with 1 week off per 4-week cycle. The Safety Committee reviewed data from phase I before moving to phase II. The primary endpoint of phase II (dose expansion) is an adequate number of responders based on PFS at 4 months and/or objective clinical response per RECIST v1.1. Results: As of September 21, 2018, 8 phase I subjects and 13 phase II subjects were enrolled and treated (9 males and 12 females, median age 67 years). The most common (≥ 15%) related adverse events were nausea, diarrhea, fatigue, alopecia, decreased appetite, rash, vomiting, and anemia. Fourteen subjects had at least one on-study scan (after 2 cycles). One subject experienced a complete response (CR) after 6 cycles of therapy with normalization of CA19.9 (-76%). Three subjects exhibited a partial response (PR): two after 2 cycles (39-47%) and one after 4 cycles of therapy (36%). Eight subjects had stable disease for at least 2 months, and 4 subjects had PFS of at least 4 months. The disease control rate (CR+PR+SD) was 86% in evaluable subjects while the overall response rate (CR+PR) was 29%. Conclusions: RX-3117 in combination with nab-pac appears to be safe and well tolerated in subjects with met-PC. Antitumor activity per RECIST was observed in 12 subjects. Phase II of the clinical study is currently ongoing. Clinical trial information: NCT03189914.

BEATcc (ENGOT-Cx10/GEICO 68-C/GOG3030/JGOG1084): A randomized, open label, phase III study of cisplatin and paclitaxel chemotherapy with bevacizumab (CTx plus B) with or without atezolizumab (Atz) as first-line treatment for metastatic, persistent, or recurrent (m/r) carcinoma of the cervix (CCx).

TPS5594 Background: The combination of CTx plus B is first line treatment for most patients (pts) with m/r CCx not amenable for local therapy based on GOG240 results. GOG240 regimen showed an improvement in overall survival (OS) compared to CTx alone: 16.8 vs. 13.3 months (HR 0.77, 95% CI 0.62–0.95, p = 0.007). However, further improvement in first line therapy outcomes is an unmet need. Immune-checkpoint inhibitors are breakthrough therapies in several tumor types, and their development in CCx is supported by a strong scientific rationale. Human papillomavirus infection (HPV) causes more than 90% of CCx cases. PD-L1 is a HPV biomarker and is found frequently up-regulated in CCx. Nivolumab and pembrolizumab (Pb) (anti-PD-1 antibodies) have shown response rates of 26.3% and 14.3%, respectively, in pretreated m/r CCx. This has led to the recent FDA approval of Pb in pretreated PD-L1+ m/r CCx. The BEATcc trial (NCT03556839) evaluates the addition of the anti-PD-L1 agent Atz to GOG240 regimen as first line treatment for m/r CCx, following the synergistic rationale between anti-VEGF agents and PD-1/PD-L1 blockade. Methods: Eligible pts: m/r CC with adequate organ function. Pts will be randomized 1:1 to either Arm A (control): C 50 mg/m2 + Tx 175mg/m2 + B 15 mg/kg (CTx plus B) i.v. D1 Q3W or Arm B (experimental): CTx plus B + Atz 1200 mg i.v. D1 Q3W. Stratification factors: prior chemo-radiation, histology and Chemotherapy backbone (CTx vs carboplatin-Tx). Treatment is planned until disease progression, unacceptable toxicity or withdrawal of consent. Pts with a complete response after ≥6 cycles or those with unacceptable CTx toxicity may be allowed to continue only on biologics therapy. An Independent Data Monitoring Committee will analyze the safety of the first 12 pts in the experimental arm completing 2 treatment cycles. The primary endpoint is OS. The study started enrolling in October 2018 and will enroll approximately 404 pts across Europe, Japan, and the US. Clinical trial information: NCT03556839.

PurposeThis phase II study investigated the efficacy and safety of cetuximab combined with standard oxaliplatin-based chemotherapy (infusional fluorouracil, leucovorin, and oxaliplatin [FOLFOX-4]) in the first-line treatment of epidermal growth factor receptor–expressing metastatic colorectal cancer (mCRC).Patients and MethodsThe activity of cetuximab plus oxaliplatin was investigated in colon cancer cell lines and xenograft models. In the clinical study, patients with mCRC received on day 1 of a 14 day cycle, cetuximab (initial dose 400 mg/m2during week 1, then 250 mg/m2weekly) followed by FOLFOX-4 (oxaliplatin 85 mg/m2on day 1; leucovorin 200 mg/m2on days 1 and 2, followed by fluorouracil 400 mg/m2bolus then 600 mg/m2intravenous infusion during 22 hours on days 1 and 2).ResultsThe preclinical studies confirmed the supra-additive activity of cetuximab to oxaliplatin. In the clinical study, 43 patients were included, with a median age of 65 years (range, 43 to 78 years). Response rates (RRs) were 79% (unconfirmed) and 72% (confirmed), with 95% disease control. Median progression-free survival (mPFS) and median duration of response were 12.3 and 10.8 months, respectively. Ten patients (23%) underwent resection with curative intent of previously unresectable metastases. After a median follow-up of 30.5 months, median overall survival (mOS) was 30.0 months. Cetuximab did not increase the characteristic toxicity of FOLFOX-4 and was generally well tolerated.ConclusionCetuximab in combination with FOLFOX-4 is a highly active first-line treatment for mCRC, showing encouraging RR, mPFS, and mOS values. The treatment resulted in a high resectability rate, which could potentially result in an improved cure rate. This combination is under phase III development.

Purpose To determine whether irinotecan plus oxaliplatin (IROX) is superior to irinotecan alone in patients with metastatic colorectal cancer (CRC) previously treated with single-agent fluoropyrimidines. Patients and Methods A phase III, randomized, open-label, multicenter study of patients with metastatic or recurrent CRC that had progressed or recurred during or after adjuvant or first-line fluoropyrimidines (fluorouracil/leucovorin or capecitabine, the latter only for metastatic CRC). Patients received IROX (irinotecan 200 mg/m2 plus oxaliplatin 85 mg/m2) or irinotecan alone (350 mg/m2) every 3 weeks. Results At the data cutoff (when 447 of 628 randomly assigned patients had died), median overall survival was 13.4 months (95% CI, 12.4 to 14.7 months) and 11.1 month (95% CI, 10.0 to 12.7 months) in the IROX and irinotecan groups, respectively (hazard ratio = 0.78; 95% CI, 0.65 to 0.94; P = .0072). Overall response rate (22% v 7%, respectively; P < .0001), median time to progression (5.3 v 2.8 months, respectively; P < .0001), and improvement in tumor-related symptoms (32% v 19%, respectively; P = .0072) were also improved with IROX as compared with irinotecan. With the exception of granulocytopenia (25% v 13%), diarrhea (28% v 23%), and sensory disturbances (5% v 0%), grade 3 to 4 toxicities were comparable between the IROX and irinotecan groups, respectively. Conclusion IROX is an effective treatment for metastatic CRC that has progressed after first-line fluoropyrimidine therapy. IROX improves efficacy compared with irinotecan alone, providing an additional option in the postadjuvant or second-line treatment setting for patients who experience treatment failure with single-agent fluoropyrimidine therapy.

e15550 Background: The combination of anti-VEGF or anti-EGFR targeted drugs with chemotherapy is the standard first-line therapy for metastatic colorectal cancer (mCRC), and the followed maintenance treatment is an optional approach to balance the efficacy and toxicity. However, studies regarding the maintenance strategies based on antiangiogenic TKIs are limited currently. Anlotinib, a novel oral multi-target TKI which can inhibit both tumor angiogenesis and tumor cell proliferation simultaneously, substantially prolonged the PFS with manageable toxicity for refractory mCRC in the phase III ALTER0703 clinical trial. Here we report an update on the effectiveness and safety of anlotinib plus XELOX as first-line treatment followed by anlotinib monotherapy for mCRC. Methods: In this open label, single-arm, multicenter phase II clinical trial, 53 mCRC patients without prior systemic treated, aged 18-75 and an ECOG performance status of 0 or 1 were planned to recruit. Eligible patients received capecitabine (1000 mg/m2, po, d1-14, q3w) and oxaliplatin (130 mg/m2, iv, d1, q3w) plus anlotinib (10mg, po, d1̃14, q3w) treatment for 6 cycles. After 6 cycles of inducing therapy, patients would receive anlotinib (12mg, po, d1̃14, q3w) as maintenance therapy until disease progression or intolerable adverse events (AEs). The primary endpoint was PFS; Secondary endpoints included ORR, DCR, DOR and safety. Results: By the data analysis cutoff date of January 22, 2021, a total of 18 patients were enrolled, of which 12 patients were available for efficacy assessment. In best overall response assessment, there were 50.0% PR (6/12), 33.3% SD (4/12) and 16.7% PD (2/12). The ORR was 50.0% (95% CI, 21.1-78.9%) and DCR was 83.3% (95% CI, 51.5-97.9%). The longest duration of treatment was 8.8 months and the response was still ongoing. The median PFS was not reached. The most common treatment related adverse events (TRAEs) of any grade (≥20%) were leukopenia, hypertension, neutropenia, diarrhea, fatigue, hypertriglyceridemia. Grade 3/4 TRAEs included hypertension (22.2%), hypertriglyceridemia (11.1%), lipase elevated (11.1%) and neutropenia (5.6%). No grade 5 AEs occurred. Conclusions: The update results suggested that anlotinib combined with XELOX as first line regimen followed by anlotinib monotherapy showed promising anti-tumor activity and manageable safety for patients with mCRC. And the conclusions needed to be confirmed in trials continued subsequently. Clinical trial information: ChiCTR1900028417.

e15100 Background: Irinotecan and 5-Fluorouracil based combination is an effective regimen for mCRC. Capecitabine, an oral fluoropyrimidine, is a convenient alternative to intravenous 5- Fluorouracil. This study aims to systematically review all published and unpublished controlled phase II and III trials of XELIRI combination, used in first line treatment of mCRC, reported from 2000–2008, to describe its efficacy and safety. Methods: A literature search of MEDLINE, EMBASE, CINAHL and proceedings from ASCO, ESMO and WGIC was conducted. The primary end point was response rate (RR), secondary endpoints include: time to progression (TTP), overall survival (OS) and toxicity. Results: Thirty non-randomised phase II trials (n = 1380) along with 6 randomised phase II and 3 phase III trials, were included (pooled n = 1478). The daily dose of capecitabine ranged from 1,800 mg/m2 to 2,500 mg/m2 for 7 to 14 days per cycle and the dose of irinotecan varied from 180mg/m2 to 350 mg/m2, over a 3 week period per cycle. Amongst the non-randomised studies, the median patient age was 61 years (53–72).The median RR was 46.75% (25–78%). The median reported TTP was 7.9 months (mo) (5- 9.9 mo) and the median OS was 15.6 months (7–24.8 mo). Grade 3–4 toxicity incidence was: diarrhoea (21.5%), neutropenia (12%), vomiting (12.5%), fatigue (6%) and Hand-foot syndrome (6%). The pooled incidence of febrile neutropenia was 2.5%. Amongst the randomised trials, the comparator regimens were XELOX or FOLFIRI. Median age was 65 years (61–74). RR for XELIRI was 39% (34–56%) compared to 47% (27–61.8%) for the non XELIRI comparator arms. Median reported TTP was 8.2 mo (5.7–12.5 mo) for the XELIRI arms and 9.2 mo for the comparator arms. Conclusions: XELIRI is an effective and feasible regime in the first line management of mCRC. However the optimal role of this combination remains to be established. No significant financial relationships to disclose.

7081 Background: Cisplatin is one of the most active drugs available in MPM while bortezomib has shown some activity in single agent phase II studies against MPM. This was a prospective phase II study of cisplatin and bortezomib (CB) in the first line treatment of MPM. Methods: Patients with histological proven MPM, with performance status (PS) 0/1, were eligible. The doses were cisplatin 75mg/m2 /3 wks and bortezomib 1.3mg/m2 day 1, 4, 8, 11 every 3 wks. The primary end-point was progression free survival rate at 18 wks (PFSR=18). The 2-stage Simon design (a=0.1; b = 0.05, P0=0.50 and P1=0.675) was used. In the first step of the study 37 eligible patients were planned. If more than 19 patients were alive and free of progression at 18 wks the total sample size was increased to 76 eligible patients. Results: Between 2007 and 2010 82 patients were entered. The median follow-up time is 32.3 months The median age was 55 years (range: 22-77yrs), male/female: 55/27 , PS 0/1: 9/73, Stage T1: 10%; T2: 42%, T3: 25%; T4: 23% and N0: 57%; N1: 4%; N2: 33%; N3: 6%. The median number of cycles received was 4 and 38% received 6 cycles. Cisplatin/ bortezomib dose intensity was 98/ 80%. Toxicity (grade 3/4): neutropenia 10%, thrombocytopenia 11%, anaemia 1%. Grade 3-4 hyponatraemia/ hypokalaemia occurred in 46/ and 17%. Grade 2 tinnitus, grade 3 fatigue occurred in 16%, and 12%, of patients. Motor/sensory/other neurotoxicity was grade 1: 6/28/7%, grade 2: 2/26/2% and grade 3: 1/7/2% respectively. There were 2 toxic deaths at 32 and 74 days due to acute pneumonitis and cardiac arrest. The PFRS-18 (including symptomatic progression) was 53% (80% confidence intervals, CI, 42-64%). The overall survival was 13.5 months (95% CI 10.5-15) with 56% (95% CI 44-66%) alive at 1 year. The PFS was 5.1 months (95% CI 3.3-6.5). Conclusions: On the basis of the PFRS-18, the null hypothesis could not be rejected, although CB gave predictable toxicity and was as active as other reported regimens in MPM.
