Detailed Description:

For this study sensitive or refractory SCLC patients (refractory to prior chemotherapy

defined as having experienced no response or a relapse within 90 days after the end of

chemotherapy) will be eligible. In total, around 130 patients will be enrolled, around 30

evaluable patients in phase I and 100 patients in phase II.

The study will consist of two parts:

A preceding Phase I part will be performed to identify the Recommended Dose of veliparib to

be administered in the Phase II part in combination with topotecan at the dose regimen of

1.25 mg/m2 (on days 1-5 of a 3 week cycle [d1-5q21d]). Each patient will be subjected to an

initial cycle of topotecan monotherapy (1.25 mg/m2 on day 1-5 of a 3 week cycle); this run-in

cycle shall prove topotecan tolerance of the candidates. Only patients who do not reveal any

DLTs receive further treatment with combination therapy. In a dose-escalating 3+3 design the

RD of veliparib for the subsequent Phase II part of the study will be defined during a

maximum of 5 cycles combination therapy.

The Phase II part will follow upon completion of Phase I.
