Trial Outcomes & Findings for 4B951, Combination Chemotherapy in Treating Patients With Bladder Cancer (NCT NCT00005047)

NCT ID: NCT00005047

Last Updated: 2017-06-08

Results Overview

p53 positive patients randomized to MVAC (arm I) compared to p53 positive patients randomized to observation (arm II). Time from registration to the first observation of disease recurrence, censoring patients who died of unrelated causes. Probabilities of recurring were based on cumulative incidence curves. Recurrence is defined as first radiological appearance of bladder cancer, per local standard of care.

Participant Flow

Patients with stage pT1/T2N0M0 urothelial cancer who had undergone a radical cystectomy within the prior 9 weeks were eligible for enrollment. Twenty-two patients who were registered were never assigned to a group after enrolling due to: missing baseline documentation (5), incorrect disease stage (13), and patient withdrawal (4).

PRIMARY outcome

Timeframe: 5 years

p53 positive patients randomized to MVAC (arm I) compared to p53 positive patients randomized to observation (arm II). Time from registration to the first observation of disease recurrence, censoring patients who died of unrelated causes. Probabilities of recurring were based on cumulative incidence curves. Recurrence is defined as first radiological appearance of bladder cancer, per local standard of care.

SECONDARY outcome

Timeframe: 5 years

p53 positive patients randomized to MVAC (arm I) compared to p53 positive patients randomized to observation (arm II). Survival is calculated from registration to death due to any cause. Probabilities of survival were based on the Kaplan-Meier product-limit method.

Population: This analysis compares p53 positive patients (combined arms I, II, and IV) to p53 negative patients (arm III).

Patients with tumors demonstrating alteration in p53 compared to patients with no p53 alterations. Probabilities of recurring were based on cumulative incidence curves. Recurrence is defined as first radiological appearance of bladder cancer, per local standard of care.
