What was measured
A Neuropathy Questionnaire measures the participant's symptom experience over the past 7 days using a 5-point Likert scale of "not at all" (0) to "very much" (4). There are 2 items that ask if the participant's feet (item 1) or hands (item 2) feel numb or have prickling/tingling feelings. The Neuropathy Questionnaire was used to determine the chemotherapy-induced peripheral neuropathy (CIPN) status of each participant as well as provide an anchor for interpreting the impact of CIPN on participant's QoL. Two thresholds were used. For the first, a participant was determined to have CIPN if a score greater than 0 ("not at all") was recorded for either item. For the second, CIPN was assigned if a participant recorded a score greater than 1 ("a little bit").
Analysis population: Intent-to-treat Population. Only those participants with data available at the indicated time points were analyzed.
Groups in this outcome
Non-gBRCA Niraparib
Participants without germline BRCA mutation received oral dose of niraparib 300 mg once daily orally in 28-day cycles until disease progression.
Non-gBRCA Placebo
Participants without germline BRCA mutation received matching placebo once daily orally in 28-day cycles until disease progression
