TPS600 Background: Radical surgery ± cisplatin‐based (neo)adjuvant therapy (NAT) is the mainstay of treatment for invasive urothelial carcinoma of the upper urinary tract (UTUC) or bladder (UBC), but recurrence rates are high. Furthermore, many patients (pts) are unable to receive NAT because of cisplatin ineligibility. Fibroblast growth factor receptor 3 (FGFR3) genetic alterations occur in up to 70% of UTUC and up to 20% of UBC, and may constitute a potential candidate for targeted therapy. Infigratinib (BGJ398), a selective FGFR1–3 inhibitor, has shown promising clinical activity and tolerability in pts with advanced urothelial carcinoma having FGFR3 alterations [Pal et al. Cancer Discov 2018]. PROOF 302 has been designed to investigate the efficacy and safety of infigratinib versus placebo as adjuvant therapy in pts with high-risk invasive urothelial carcinoma and FGFR3 alterations. Methods: PROOF 302 is a randomized, double-blind, placebo-controlled, phase III study of approx. 218 pts. Adults with high-risk invasive UTUC or UBC with FGFR3 genetic alterations (i.e. mutations, gene fusions or translocations) who are ≤120 days following surgical resection and ineligible for cisplatin-based adjuvant chemotherapy or with residual disease after cisplatin- based NAT are eligible. Those who received non cisplatin-based NAT are eligible if they have residual disease and are ineligible for adjuvant cisplatin. Pts receive oral infigratinib 125 mg or placebo (1:1 ratio) once daily on days 1–21 every 28 days for up to 52 weeks or until disease recurrence, unacceptable toxicity or death. Primary endpoint: centrally reviewed disease-free survival (DFS). Secondary endpoints: DFS including intraluminal low-risk recurrence; metastasis-free survival; overall survival; DFS (per investigator); safety and tolerability. Exploratory endpoints include: quality of life; pharmacokinetics; cell-free DNA (cfDNA) and/or RNA for resistance mechanisms. The study will involve approximately 120 centers worldwide. Enrollment is expected to begin in January 2020. Trial registration: EudraCT 2019-003248-63. Clinical trial information: EudraCT 2019-003248-63.

PROOF 302 has been designed to investigate the efficacy and safety of infigratinib versus placebo as adjuvant therapy in patients with high-risk invasive urothelial carcinoma and susceptible FGFR3 alterations. Methods: PROOF 302 is a randomized, double-blind, placebo-controlled, phase III study of approx. 218 patients. Adults with high-risk invasive UTUC or UBC with susceptible FGFR3 genetic alterations (i.e. activating mutations, gene fusions or translocations) who are ≤120 days following surgical resection and ineligible for or refusing cisplatin-based adjuvant chemotherapy or with residual disease after cisplatin-based NAC are eligible. Those who received non cisplatin-based NAC are eligible if they have residual disease and are ineligible for adjuvant cisplatin.

Abstract Background Progress has been made in the reduction of under-five mortality in India; however, neonatal mortality is reducing at a slower rate. Efforts are required to bring down neonatal mortality in order to attain the Sustainable Development Goal-3. Prevention of sepsis among the high-risk, vulnerable low birth weight neonates by a newer intervention with probiotic supplementation is promising. Methods A phase III, multicenter, randomized, double-blind, placebo-controlled study is being conducted at six sites in India. A total of 6144 healthy low birth weight (LBW) infants fulfilling the eligibility criteria would be enrolled within the first week of life, after obtaining written informed consent from the parents of the infant. Randomization in 1:1 ratio, stratified by site, sex, and birth weight, would be done through an interactive web response system (IWRS) using a standard web browser and email service. Vivomixx®, a probiotic containing a mix of 8 strains of bacteria, in a suspension form standardized to deliver 10 billion CFU/ml, or an organoleptically similar placebo would be fed to enrolled infants in a 1-ml/day dose for 30 days. The follow-up of enrolled infants for 60 days would take place as per a pre-specified schedule for recording morbidities and outcome assessments at the six participating sites. Screening for morbidities would be conducted by trained field workers in the community, and sick infants would be referred to designated clinics/hospitals. A physician would examine the referred infants presenting with complaints and clinical signs, and blood samples would be collected from sick infants for diagnosis of neonatal sepsis by performing sepsis screen and blood culture. Appropriate treatment would be provided as per hospital protocol. The study would be implemented as per the MRC guideline for the management of Global Health Trials in accordance with ICH-GCP and Indian Regulatory guidelines. A contract research organization would be engaged for comprehensive monitoring and quality assurance. The final analysis would be conducted in a blinded manner as per the statistical analysis plan (SAP) to estimate the primary outcomes of sepsis, possible serious bacterial infection (PSBI), and secondary outcomes. The codes will be broken after DMC permission. The protocol has been reviewed by the Research Ethics Committee of the Liverpool School of Tropical Medicine (REC-LSTM), from Research Ethics Committees of the six subject recruitment participating sites. Discussion This adequately powered and well-designed trial would conclusively answer the question whether probiotics can prevent neonatal sepsis in the high-risk group of low birth weight infants as indicated by a pilot study in 1340 LBW infants, evidence from systematic reviews of hospital-based studies, and a primary study on healthy newborns in Orissa. Results of the study would be generalizable to India and other low–middle-income countries. Trial registration Clinical Trial Registry of India (CTRI) CTRI/2019/05/019197. Registered on 16 May 2019

391 Background: The standard of care (SOC) for patients (pts) with MIUC is radical surgery ± cisplatin-based neoadjuvant chemotherapy (chemo), but many pts are cisplatin-ineligible. There is no conclusive evidence supporting adjuvant chemo in pts who did not receive neoadjuvant chemo and in those with residual disease after neoadjuvant cisplatin. This phase 3 trial of adjuvant nivolumab (NIVO) vs placebo (PBO) in pts with MIUC after radical surgery ± neoadjuvant cisplatin (CheckMate 274) aims to address an unmet need in these pts. We report the initial results. Methods: This is a phase 3, randomized, double-blind, multicenter trial of NIVO vs PBO in pts with high-risk MIUC (bladder, ureter, or renal pelvis) after radical surgery. Pts were randomized 1:1 to NIVO 240 mg Q2W or PBO for ≤ 1 year of adjuvant treatment. Pts had radical surgery within 120 days ± neoadjuvant cisplatin or were ineligible/declined cisplatin-based chemo, evidence of UC at high risk of recurrence per pathologic staging, were disease-free by imaging, and ECOG PS ≤ 1. Primary endpoints: disease-free survival (DFS) in all randomized pts (ITT population) and in pts with tumor PD-L1 expression ≥ 1%. DFS was stratified by nodal status, prior neoadjuvant cisplatin, and PD-L1 status. Non–urothelial tract recurrence-free survival (NUTRFS) in ITT pts and in pts with PD-L ≥ 1% is a secondary endpoint. Safety is an exploratory endpoint. Results: In total, 353 pts were randomized to NIVO (PD-L1 ≥ 1%, n = 140) and 356 pts to PBO (PD-L1 ≥ 1%, n = 142). The primary endpoint of DFS was met in ITT pts (median follow-up, 20.9 mo for NIVO; 19.5 mo for PBO) and in pts with PD-L1 ≥ 1%. DFS and NUTRFS were improved with NIVO vs PBO in both populations (Table). DFS improvement with NIVO was generally consistent across subgroups. Grade 3–4 treatment-related adverse events (TRAEs) occurred in 17.9% and 7.2% of pts in the NIVO and PBO arms, respectively. Conclusions: NIVO demonstrated a statistically significant and clinically meaningful improvement in DFS vs PBO for MIUC after radical surgery, both in ITT pts and pts with PD-L1 ≥ 1%. AEs were manageable and consistent with previous reports. These results support adjuvant NIVO as a new SOC for pts with MIUC with high risk for recurrence despite neoadjuvant chemo or those ineligible for and/or declining cisplatin-based chemo.

Abstract Adjuvant chemotherapy is the current standard treatment for stage III colorectal cancer after curative resection. However, the prognosis of stage III colorectal cancer is still poor even after curative resection and adjuvant chemotherapy. Several observational studies suggested that the anti-tumor effect of aspirin. Therefore, we planned a randomized double-blind placebo-controlled phase III trial, which commenced in Japan in March 2018, to confirm the superiority of aspirin over placebo added to adjuvant chemotherapy in terms of disease-free survival (DFS) for stage III colorectal cancer patients after curative resection. A total of 880 patients will be accrued from 20 Japanese institutions within 3 years. The primary endpoint is DFS and the secondary endpoints are overall survival, relapse-free survival, relative dose intensity, adverse events, and serious adverse events. This trial has been registered at Japan Registry of Clinical Trials as jRCTs031180009 (https://jrct.niph.go.jp/detail/589).
