Brief summary

The purpose of this research study is to determine the highest and safest dose of the experimental drug veliparib when combined with nivolumab. We will also study how safely this combination of medication can be given in advanced cancer and lymphoma and benefits of receiving this therapy. Nivolumab is currently approved in certain cancers such as melanoma, lung cancer and kidney cancer. Veliparib is not yet approved for use in the United States, and is considered experimental. Veliparib inhibits (blocks) the activity of the enzyme PARP. This blocking activity may prevent the cancer cell from repairing itself and resume growing. Nivolumab increases T cells in your immune system, which allows your immune system to attack the cancer. We think the combination of these drugs will be more effective against your cancer.

Detailed description

PRIMARY OBJECTIVES: I. To identify maximum tolerated dose (MTD) for the combination treatment of nivolumab and veliparib in patients with advanced refractory solid cancers and lymphoma. SECONDARY OBJECTIVES: I. To evaluate the safety and tolerability of nivolumab and veliparib in patients with advanced refractory solid cancers and lymphoma with and without mutations in selected DNA repair genes. II. To evaluate the efficacy of treatment with nivolumab and veliparib in this population by objective response rate (ORR, defined as partial response \[PR\] + complete response \[CR\]), clinical benefit rate (CBR, defined as stable disease \[SD\] for \>= 12 weeks, PR, + CR), and progression free survival (PFS, defined as the time from treatment initiation to documented disease progression) using Response Evaluation Criteria in Solid Tumors (RECIST) criteria version (v)1.1 or Lugano criteria. III. To evaluate efficacy of treatment with nivolumab and veliparib in this population by ORR, CBR, and immune-related PFS (irPFS) using irRECIST criteria. IV. To evaluate overall survival (OS) in this population at 3 years from the start of treatment. V. To evaluate the proportion of patients alive and progression free at 24 weeks in this population. VI. To evaluate ORR to nivolumab and veliparib in patients with prior exposure to single agent PD-1/PD-L1 inhibitors. TERTIARY OBJECTIVES: I. To evaluate if any of the following predict response to veliparib in combination with nivolumab: tissue PD-L1 protein expression, immune cell infiltration markers. II. To demonstrate the pharmacodynamic effects of veliparib and nivolumab on biomarkers including PD-L1, TILs, T cell subpopulations, and T cell receptor genotype. III. To explore the pattern of clonal changes through circulating cell free DNA assay. IV. To assess the dynamic change in both immune and genomic biomarkers in blood that may correlate with response to veliparib. OUTLINE: This is a dose-escalation study of veliparib. Patients receive veliparib orally (PO) twice daily (BID) on day 1 and nivolumab intravenously (IV) over 30 minutes on days 1 and 15 of courses 1-4 and IV over 60 minutes on day 1 of subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months and then every 6 months for 3 years.

Number of Patients Alive and Progression Free at 24 Weeks

To evaluate the number of patients alive and progression free at 24 weeks. -Per RECIST v. 1.1 (for solid tumors) progression is defined as : At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression.) -Lugano 2014 classification, scored on a Deauville 5-point scale (an internationally-recommended scale using FDG PET-CT in the initial staging and assessment of treatment response i Hodgkin lymphoma (HL) and certain types of non-Hodgkin lymphomas (NHL). Per Lugano criteria: Partial metabolic disease (PMD):Score 4 or 5 with an increase in intensity of uptake from baseline and/or new FDG-avid foci consistent with lymphoma at interim or end-of-treatment assessment.

Time frame: At 24 weeks

Population: 2 patients not included in these results as they came off treatment before 24 weeks - one withdrew consent and 1 came off treatment for palliative radiation.

ORR (Overall Response Rate)

Overall response rate or ORR, (partial response (PR) + complete response (CR)) will be evaluated using RECIST criteria v1.1 or Lugano 2014 classification for assessment of Lymphoma. Per RECIST v. 1.1: PR= : At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. CR= Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Per Lugano 2014 classification, scored on a Deauville 5-point scale (an internationally-recommended scale using FDG PET-CT in the initial staging and assessment of treatment response in Hodgkin lymphoma (HL) and certain types of non-Hodgkin lymphomas (NHL). * Partial metabolic response (PMR): score of 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size. * Complete metabolic response (CMR): Score of 1, 2 or 3 in nodal or extranodal sites with or without a residual mass

Time frame: after 2 cycles at first response time point (1 cycle = 28 days)

Overall Survival (OS)

Overall Survival is defined as the time from treatment initiation until death due to any cause, assessed up to 3 years from the start of treatment.

Time frame: From the start of treatment and up to 3 years, where 1 cycle =28 days, and range of cycles is 1-12.

Progression Free Survival (PFS)

To evaluate Progression Free Survival (PFS) for patients treated with nivolumab and veliparib, defined as the time from treatment initiation to documented disease progression. Evaluated by RECIST criteria v1.1 for solid tumors or Lugano 2014 classification for assessment of Lymphoma. RECIST v. 1.1 definition for PD (Progressive disease): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
