Infigratinib

Participants will be randomly assigned (1:1) to receive oral infigratinib administered once daily for the first 3 weeks (21 days) of each 28-day cycle for a maximum of 52 weeks

Participants will be randomly assigned (1:1) to receive oral placebo administered once daily for the first 3 weeks (21 days) of each 28-day cycle for a maximum of 52 weeks

Participants randomly assigned to infigratinib will receive hard gelatin capsules for oral administration of infigratinib 125 mg once a day (administered as one 100-mg capsule and one 25-mg capsule) using a 3 weeks on (Days 1-21) /1 week off (Days 22-28) dosing schedule.

Participants randomly assigned to placebo will receive placebo matching in appearance the investigational product (infigratinib), which will be provided as hard gelatin capsules for oral use and will be administered once daily on a 3 weeks on (Days 1-21) /1 week off (Days 22-28) dosing schedule.

This is a Phase 3 multicenter, double-blind, randomized, placebo-controlled study to evaluate the efficacy of infigratinib (an oral targeted FGFR1-3 inhibitor) versus placebo, as adjuvant treatment following surgery in adult subjects with invasive urothelial carcinoma and susceptible FGFR3 genetic alterations (mutations, and gene fusions or rearrangements) who have disease that is considered at high risk for recurrence with surgery alone. The study enrolls subjects with either bladder cancer post radical cystectomy or upper tract urothelial cancer post distal ureterectomy and/or nephrectomy. Study treatment is randomized 1:1 between infigratinib or placebo with treatment up to 1 year or until invasive local, distal, or metastatic disease recurrence confirmed by independent imaging reviewer.

Participants will be randomly assigned (1:1) to receive oral infigratinib phosphate or placebo

As a double-blind study, participants, investigators, study monitor(s) and the clinical study team will be blinded to the treatment administered.

Oral Infigratinib for the Adjuvant Treatment of Subjects With Invasive Urothelial Carcinoma With Susceptible FGFR3 Genetic Alterations

Phase 3, Multicenter, Double-Blind, Randomized, Placebo-Controlled Trial of Infigratinib for the Adjuvant Treatment of Subjects With Invasive Urothelial Carcinoma With Susceptible FGFR3 Genetic Alterations (PROOF 302)

DFS was defined as the number of months from date of randomization to local/regional invasive or metastatic recurrence or death due to any cause (referred as DFS event), whichever occurs earlier.

Due to early termination of the study by the sponsor, results will focus primarily on the primary and key secondary endpoints of the study. Due to early termination of the study by the sponsor, data were censored for 85.0% to 89.5% of all subjects. Data cutoff 28 Feb 2023.

DFS was defined as the number of months from date of randomization to local/regional invasive or metastatic recurrence or death due to any cause (referred as DFS event), whichever occurs earlier. Due to early termination of the study by the sponsor, data were censored for 85.0% to 89.5% of all subjects. Data cutoff 28 Feb 2023.

MFS was defined as the time from randomization to any metastatic recurrence as determined by the investigator, or death due to any cause, whichever occurred earlier. Due to early termination of the study by the sponsor, data were censored for 85.0% to 89.5% of all subjects. Data cutoff 28 Feb 2023.

Overall survival time was defined as the number of months from randomization to death. Due to early termination of the study by the sponsor, data were censored for 85.0% to 89.5% of all subjects. Data cutoff 28 Feb 2023.

AEs were assessed by the investigator according to the CTCAE version 5.0 and coded using MedDRA version 23.1.

Treatment-emergent AEs are reported and include all AEs with onset after the first administration of study treatment and up to last administration of study treatment + 30 days if subjects ended study treatment. For a subject who had not ended study treatment, all the AEs after the first administration of study drug were considered treatment-emergent.

Region of Enrollment

Functional status was assessed at baseline using the Eastern Cooperative Oncology Group Performance Scale (ECOG PS), defined as follows:

0. Fully active, able to carry out all pre-disease performance without restriction.

1. Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature.
2. Ambulatory and capable of all selfcare but unable to carry out any work activities; up and about more than 50% of waking hours.
3. Capable of only limited selfcare; confined to bed or chair more than 50% of waking hours.
4. Completely disabled.

ECOG PS

Primary Site of Cancer

Histological Subtype

Tumor (T). T1, T2, T3, T4: Refers to the size and/or extent of the main tumor. The higher the number after the T, the larger the tumor or the more it has grown into nearby tissues.

Screening Diagnosis Category (Pathologic Stage at Definitive Surgery) - Tumor (T)

Node (N) refers to the number of nearby lymph nodes that have cancer. NX: Cancer in nearby lymph nodes cannot be measured; N0: There is no cancer in nearby lymph nodes; N1, N2, N3: Refers to the number and location of lymph nodes that contain cancer. The higher the number after the N, the more lymph nodes that contain cancer.
