Lung Cancer Clinical Trial
Niraparib, Temozolomide and Atezolizumab in Treating Patients With Advanced Solid Tumors and Extensive-Stage Small Cell Lung Cancer With a Complete or Partial Response to Platinum-Based First-Line Chemotherapy
Summary
This phase Ib/II trial studies the best dose of temozolomide and how well it works with niraparib and atezolizumab in treating patients with solid tumors that have spread to other places in the body (advanced) and extensive-stage small cell lung cancer with a complete or partial response to platinum-based first-line chemotherapy. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. 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. Giving temozolomide, niraparib and atezolizumab may work better in treating patients with advanced solid tumors and extensive-stage small cell lung cancer.
Full Description
PRIMARY OBJECTIVES:
I. Determine the recommended phase II dose (RP2D) of temozolomide in combination with niraparib and atezolizumab. (Phase Ib) II. Evaluate the efficacy of niraparib plus temozolomide plus atezolizumab at RP2D (Arm A) compared with atezolizumab (Arm B) as measured by progression-free survival (PFS). (Phase II)
SECONDARY OBJECTIVES:
I. To evaluate the efficacy of niraparib plus temozolomide plus atezolizumab compared with atezolizumab alone, as measured by overall survival (OS).
II. To evaluate the efficacy of niraparib plus temozolomide plus atezolizumab compared with atezolizumab alone, as measured by objective response rate (ORR) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
III. To evaluate the safety of niraparib plus temozolomide plus atezolizumab compared with atezolizumab alone as measured by adverse events (AEs).
EXPLORATORY OBJECTIVE:
I. To assess participant-reported outcomes on health-related quality of life and adverse events.
OUTLINE: This is a dose-escalation study of temozolomide. Patients are randomized to 1 of 2 arms.
ARM A: Patients receive temozolomide orally (PO) once daily (QD) on days 1-5 and niraparib PO QD on days 1-28. Cycles repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive standard of care atezolizumab intravenously (IV) every 3 weeks in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive standard of care atezolizumab IV every 3 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, every 8 weeks for 24 weeks, and then every 12 weeks for up to 1 year.

Female participants of childbearing potential must have a negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. The serum pregnancy test must be negative for the participant to be eligible, and participants must agree to use a highly-effective birth control method from the time of the first study drug treatment through 180 days after the last study drug treatment, or be of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):
>= 45 years of age and has not had menses for > 1 year
Participants who have been amenorrhoeic for < 2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure.
Male participants must use a condom when having sex with a pregnant woman and when having sex with a woman of childbearing potential from the time of the first study-drug treatment through 180 days after the last study drug treatment. Contraception should be considered for a non-pregnant female partner of childbearing potential.
Male and female participants must agree not to donate sperm or eggs, respectively, from the first study-drug treatment through 180 days after the last study drug treatment.
Female participants must agree to not breastfeed during the study or for 180 days after the last dose of study treatment.
Participants must agree to not donate blood during the study or for 90 days after the last dose of study treatment.
