Testing Maintenance Therapy for Small Cell Lung Cancer in Patients With SLFN11 Positive Biomarker

May 28, 2026 updated by: National Cancer Institute (NCI)

Phase II Randomized Study of Maintenance Atezolizumab Versus Atezolizumab in Combination With Talazoparib in Patients With SLFN11 Positive Extensive Stage Small Cell Lung Cancer (ES-SCLC)

This phase II trial studies whether atezolizumab in combination with talazoparib works better than atezolizumab alone as maintenance therapy for patients with SLFN11-positive extensive-stage small cell lung cancer. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. PARPs are proteins that help repair damage to DNA, the genetic material that serves as the body's instruction book. Changes (mutations) in DNA can cause tumor cells to grow quickly and out of control, but PARP inhibitors like talazoparib may keep PARP from working, so tumor cells can't repair themselves, and they stop growing. Giving atezolizumab in combination with talazoparib may help lower the chance of extensive-stage small cell lung cancer growing and spreading compared to atezolizumab alone.

Detailed Description

PRIMARY OBJECTIVE:

I. To compare progression free survival (PFS) among participants with Schlafen family member 11 (SLFN11) positive extensive stage small cell lung cancer (ES-SCLC) randomized to atezolizumab or atezolizumab plus talazoparib as maintenance therapy.

SECONDARY OBJECTIVES:

I. To compare overall survival (OS) between the arms. II. To compare objective response rate (ORR) among participants with measurable disease between the arms, including complete response (CR) and partial response (PR) (confirmed and unconfirmed) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

III. To evaluate the frequency and severity of adverse events within each treatment arm.

TRANSLATIONAL MEDICINE OBJECTIVE:

I. To bank specimens for future correlative studies.

OUTLINE: Patients are screened for SLFN11 biomarker during Step 1: Screening Registration by submitting tumor tissue to MDACC. Patients with SLFN11 biomarker are registered to Step 2: Randomization and are randomized to 1 or 2 arms.

ARM I: Patients receive atezolizumab intravenously (IV) over 30-60 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive atezolizumab IV over 30-60 minutes on day 1 and talazoparib orally (PO) once daily (QD) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients may undergo magnetic resonance imaging (MRI) during screening. Patients undergo tumor biopsy while on study. Patients undergo computed tomography (CT) scan and blood sample collection throughout the study.

Women of reproductive potential and men must have agreed to use an effective contraception method for the duration of protocol treatment, and for 7 months after the last dose of protocol treatment. A woman is considered to be of "reproductive potential" if she has had a menses at any time in the preceding 12 consecutive months. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. However, if at any point a previously celibate participant chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with atezolizumab, breastfeeding must be discontinued prior to Step 2 Randomization

STEP 2: RANDOMIZATION: Participants with impaired decision-making capacity are eligible as long as their neurological or psychological condition does not preclude their safe participation in the study (e.g., tracking pill consumption and reporting adverse events to the investigator)
