[Study Design] This study is a single arm, multi-center phase II study of vistusertib monotherapy in patients with relapsed small cell lung cancer (SCLC) harboring RICTOR amplification. Patients will receive vistusertib monotherapy (50 mg BID per os every 12 hours) until they demonstrate objective disease progression or they meet any other discontinuation criteria.

[Primary Objective] To investigate the efficacy of vistusertib monotherapy in patients with relapsed SCLC patients harboring RICTOR amplification as 2nd or 3rd line therapy

• Provision of informed consent prior to any study specific procedures
• Men and women aged at least 18 years
• Small cell lung cancer harboring RICTOR amplification
• Patients are willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 with no deterioration over the previous 2 weeks
• Minimum life expectancy of 12 weeks
• Patients must have acceptable bone marrow, liver and renal function measured within 14 days prior to administration of study treatment as defined below:
• At least one measurable lesion that can be accurately assessed by imaging or physical examination at baseline and follow up visits.
• No history of non-autologous bone marrow transplant.

Exclusion Criteria:

• Participation in another clinical study with an investigational product during the last 21 days.
• Prior chemotherapy, biological therapy, radiation therapy, androgens, thalidomide, immunotherapy, other anticancer agents within 21 days of starting study treatment. Prior use of an investigational monoclonal antibody therapy within 3 months.
• Major surgery within 4 weeks prior to study entry (excluding placement of vascular access), or minor surgery (excluding tumour biopsies) within 14 days of first dose of study treatment.
