What was measured

Percentage of Participants with TTDR events is reported. TTDR is defined as the time from date of randomization until the first occurrence of distant recurrence or death from breast cancer.

Analysis population: Intent to treat (ITT) population included all participants who were randomized regardless of whether they received any study treatment.

Groups in this outcome

Neratinib

Patients who completed prior adjuvant trastuzumab received six 40 mg neratinib tablets (240 mg) taken orally once daily with food, preferably in the morning, continuously for one year. Therapy continued until unacceptable toxicity, recurrent disease, death, or withdrawal of consent occurred.

Placebo

Patients who completed prior adjuvant trastuzumab received six 40 mg placebo tablets (240 mg) taken orally once daily with food, preferably in the morning, continuously for one year. Therapy continued until unacceptable toxicity, recurrent disease, death, or withdrawal of consent occurred.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
