Trial overview

Official title: A Phase II, Placebo Controlled, Double-Blind, Randomized, Discontinuation Study of Lapatinib Administered Orally to Subjects with ErbB2 Positive Ovarian, Gastric/Esophageal Adenocarcinoma, Uterine Serous Papillary, or Bladder Cancer
Trial description: This study will examine the efficacy and safety of lapatinib in patients with ErbB2 positive ovarian, gastric/esophageal adenocarcinoma, uterine serous papillary, or bladder cancers.
Primary purpose:
Treatment
Trial design:
Crossover Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:

Number of participants with the indicated tumor response at 12 weeks from first dose

Timeframe: Week 12

Percentage of participants who remained progression-free 12 weeks after randomization

Timeframe: Week 12 after randomization.

Secondary outcomes:

Duration of response

Timeframe: (assessments every 12 weeks until death for withdrawn participants and every 3 weeks for participants continuing on lapatinib)

Progression-free survival (PFS)

Timeframe: From start of treatment to disease progression/death (assessments every 12 weeks until death for withdrawn participants and every 3 weeks for participants continuing on lapatinib)

Time to disease progression (TTP)

Timeframe: From start of treatment to disease progression/death (up to 83.3 weeks)

Number of participants with the indicated change in cancer antigen-125 (CA-125) levels from Day 1

Timeframe: Pre-dose and every 6 weeks until withdrawal (up to 84.1 weeks)

Incidence of MET amplification in gastric cancer

Timeframe: Performed on archived tissue collected at screening.

Incidence of ErbB2-positive participants

Timeframe: Screening
