A Phase I Study of Safety, Tolerability, and PK of AZD2811 in Patients With Advanced Solid Tumors.

This Phase I study is primarily designed to evaluate the safety and tolerability of AZD2811 at increasing doses in patients with advanced solid tumours and for whom no standard of care exists. The study will be conducted in two parts, a dose-escalation phase (Part A) and a dose expansion phase (Part B). During Part A, the dose-escalation phase, patient enrolment will proceed according to a 3+3 design where the maximum tolerated dose (MTD) or the recommended Phase II dose (RP2D) could be identified. The study will also characterize the pharmacokinetic (PK) profile of AZD2811 and will explore the potential biological activity by assessing anti-tumour activity in patients. Part B will further explore PK parameters, safety, tolerability, and preliminary anti-tumour activity of the AZD2811 RP2D as monotherapy (Group 1) in patients with relapsed/refractory SCLC.
