Brentuximab Vedotin and Nivolumab With or Without Ipilimumab in Treating Patients With Relapsed or Refractory Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
This phase I/II trial studies the side effects and best dose of ipilimumab and nivolumab when given together with brentuximab vedotin, and how well they work in treating patients with Hodgkin lymphoma that has returned after a period of improvement (recurrent) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Brentuximab vedotin is a monoclonal antibody, brentuximab, linked to a toxic agent called vedotin. Brentuximab attaches to CD30 positive cancer cells in a targeted way and delivers vedotin to kill them. It is not known whether giving brentuximab vedotin and nivolumab with or without ipilimumab may kill more cancer cells.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLT) of the combinations of brentuximab vedotin and ipilimumab, brentuximab vedotin and nivolumab, and brentuximab vedotin, ipilimumab, and nivolumab. (Phase I) II. To evaluate the complete response (CR) rate for the regimens of brentuximab vedotin and nivolumab compared to brentuximab vedotin, ipilimumab, and nivolumab. (Phase II; adult cohort [aged >= 18 years]) III. To characterize the safety and toxicity of treatment combination in the pediatric population. (Phase II; pediatric cohort [aged 12-17 years]) SECONDARY OBJECTIVES: I. To evaluate complete response (CR) rate, partial response (PR) rate and overall response rate (ORR), for the combinations of brentuximab vedotin and ipilimumab, brentuximab vedotin and nivolumab, and brentuximab vedotin, ipilimumab, and nivolumab. (Phase I) II. To evaluate the duration of remission (DOR) to these combinations and compare with the DOR achieved with the most recent prior systemic therapy. (Phase I) III. To evaluate the progression-free survival (PFS) and the overall survival (OS) in patients receiving the combination of brentuximab vedotin and ipilimumab, brentuximab vedotin and nivolumab, and brentuximab vedotin, ipilimumab, and nivolumab. (Phase I) IV. To evaluate the ORR, PR, and stable disease (SD) rate for the combinations of brentuximab vedotin and nivolumab and brentuximab vedotin, ipilimumab, and nivolumab. (Phase II) V.

(Phase II) CORRELATIVE STUDY OBJECTIVES: I. To evaluate the ability of these combinations to alter tumor specific T cell immunity. (Phase I) II. To evaluate the effects of these combinations on systemic immunity. (Phase I) III. To evaluate a panel of cytokine and T cell specific biomarkers from the peripheral blood as a potential immune signature of treatment response to therapy with these combinations for patients with relapsed/refractory Hodgkin lymphoma (HL). (Phase I) IV. To evaluate using gene expression profiling (GEP) a signature of response to these novel combinations of an antibody drug conjugate with immunomodulatory therapy. (Phase I) V. To evaluate the ability of these combinations to alter tumor specific T cell immunity, and circulating T cell phenotypes, in patients as a function of treatment response at multiple timepoints during therapy. (Phase II) VI. To evaluate peripheral blood cytokine profiles in responding and resistant patients at multiple timepoints during therapy. (Phase II) VII. To evaluate using GEP a signature of response versus (vs.) resistance to these novel combinations of an antibody drug conjugate with immunomodulatory therapy. (Phase II) VIII. To evaluate the influence of human gut microbiome dysbiosis on HL lymphomagenesis and the systemic immune response. (Phase II) IMAGING CORRELATIVE STUDY OBJECTIVES: I. To evaluate atypical response patterns with currently available response evaluation criteria. (Phase II) II. To correlate response evaluated using currently available response evaluation criteria with duration of response (PFS, event free survival [EFS], failure free survival [FFS]). (Phase II) III. To evaluate response patterns in different immunotherapy treatment schemes and correlate with historical data using chemotherapy. (Phase II) IV. To correlate imaging changes in all treatment schemes quantitatively with PFS. (Phase II) EXPLORATORY OBJECTIVES: I. Evaluate outcomes (CR, PFS) between patients with/without prior transplants. (Phase II) II. Evaluate outcomes (PFS, OS) between the patients who stay on treatment and do not go to transplant in both arms (the post auto and the few others who don't want transplant) vs the patients who go off for transplant. (Phase II) III. Evaluate outcomes (CR, PFS) in pediatric population (age 12 to < 18 years of age) vs. adult population.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum tolerated dose (MTD) of each combination (Phase I) | MTD defined as the highest dose level at which less than 33% of 6 patients experience a dose limiting toxicity, will be graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Upon completion of the trial, frequency of subjects experiencing toxicities will be tabulated. Toxicities will be assessed and graded according to CTCAE version 4.0 terminology. Exact 95% confidence intervals (CI) around the toxicity proportions will be calculated. | 21 days | 
| CR rate (Phase II) | The analysis of CR between two arms will be performed using exact Cochran-Mantel-Haenszel (CMH) test stratifying on prior brentuximab vedotin (BV) (yes versus [vs.] no) and age (< 18 vs. >= 18). Multivariable logistic regression modeling will be used to adjust for the effect of any covariates that are associated with these categorical outcomes. | Up to 10 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Complete response (CR) rate (Phase I) | Assessed using the Revised Response Criteria for Malignant Lymphoma and reported along with the 95% CI. | Up to 3 years | 
| Partial response (PR) rate (Phase I) | Assessed using the Revised Response Criteria for Malignant Lymphoma and reported along with the 95% CI. | Up to 3 years | 
| Overall response rate (ORR) rate (Phase I) | Assessed using the Revised Response Criteria for Malignant Lymphoma and reported along with the 95% CI. | Up to 3 years | 
| Duration of response (DOR) (Phase I) | DOR will be estimated using Kaplan-Meier methodology. Greenwood's formula will be used to calculate 95% CI for the Kaplan-Meier estimates. Descriptive statistics will be used to evaluate the DOR achieved with the protocol therapy and with the most recent prior systemic therapy. | From the documented beginning of response up to 3 years | 
| Overall survival (OS) (Phase I) | OS will be estimated using Kaplan-Meier methodology. Greenwood's formula will be used to calculate 95% CI for the Kaplan-Meier estimates. | From the date of study entry up to 3 years | 
| Progression-free survival (PFS) (Phase I) | PFS will be estimated using Kaplan-Meier methodology. Greenwood's formula will be used to calculate 95% CI for the Kaplan-Meier estimates. | From entry onto study up to 3 years | 
| ORR (Phase II) | Assessed using Revised Response (Cheson) and Deauville criteria. The analysis of ORR between two arms will be performed using the CMH test stratifying on prior BV (yes vs. no) and age (< 18 vs. >= 18). Multivariable logistic regression modeling will be used to adjust for the effect of any covariates that are associated with these categorical outcomes. | Up to 10 years | 
| PFS (or modified PFS) (Phase II) | PFS will be estimated using Kaplan-Meier methodology and compared between arms using stratified log-rank test. Greenwood's formula will be used to calculate 95% confidence intervals for the Kaplan-Meier estimates. Cox proportional regression model will be used to estimate hazard ratios (95% CI) and assess the relationship between other prognostic factors with time-to-event outcome. Point estimates of all endpoints will be accompanied by the corresponding 95% confidence intervals. | From randomization up to 10 years | 
| OS (Phase II) | OS will be estimated using Kaplan-Meier methodology and compared between arms using stratified log-rank test. Greenwood's formula will be used to calculate 95% confidence intervals for the Kaplan-Meier estimates. Cox proportional regression model will be used to estimate hazard ratios (95% CI) and assess the relationship between other prognostic factors with time-to-event outcome. Point estimates of all endpoints will be accompanied by the corresponding 95% confidence intervals. | From randomization up to 10 years | 
| DOR (Phase II) | DOR, will be estimated using Kaplan-Meier methodology and compared between arms using stratified log-rank test. Greenwood's formula will be used to calculate 95% confidence intervals for the Kaplan-Meier estimates. Cox proportional regression model will be used to estimate hazard ratios (95% CI) and assess the relationship between other prognostic factors with time-to-event outcome. Point estimates of all endpoints will be accompanied by the corresponding 90% confidence intervals. The DOR achieved with the most recent prior systemic therapy will be collected on the case report forms, and descriptive statistics will be used to evaluate the DOR achieved with the protocol therapy and with the most recent prior systemic therapy. | From the documented beginning of response up to 10 years |
