Clinical Trial Summary

This phase II trial tests how well giving pembrolizumab followed by chemotherapy with doxorubicin, vinblastine and dacarbazine works to treat patients with classical Hodgkin lymphoma. Pembrolizumab is a type of drug called a "monoclonal antibody (mAb)" that uses the body's immune system to help fight and kill cancer cells. Chemotherapy drugs, such as doxorubicin, vinblastine and dacarbazine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Giving pembrolizumab followed by chemotherapy may work to treat patients with classical Hodgkin lymphoma.

Description:

PRIMARY OBJECTIVE:

I. To assess the percent of patients that achieve a complete response (CR) after frontline pembrolizumab monotherapy induction, among classic Hodgkin lymphoma (cHL) patients with early unfavorable or advanced stage disease, per Lugano 2014 response criteria at positron emission tomography (PET) #2.

SECONDARY OBJECTIVES:

I. To assess the efficacy of a reduced number of cycles (2-4) of doxorubicin (adriamycin), vinblastine, and dacarbazine (AVD) when used following treatment with frontline pembrolizumab monotherapy in classic Hodgkin lymphoma (cHL), per Lugano 2014 Response Criteria.

II. To assess the safety and tolerability of sequential immunotherapy with upfront pembrolizumab followed by AVD chemotherapy in cHL per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (ver.) 5.0.

III. To assess progression-free-survival (PFS) of cHL patients who received sequential immunotherapy with upfront pembrolizumab followed by AVD chemotherapy, assessed by central review, according to Lugano 2014 Response Criteria.

IV. To assess overall survival (OS) of cHL patients who received sequential immunotherapy with upfront pembrolizumab followed by AVD chemotherapy.

V. To assess the CR rate at the end of pembrolizumab (PEM) induction by PET-computed tomography (CT) in all treated patients, regardless of number of cycles of PEM received, per Lugano 2014 Response Criteria.

OUTLINE:

INDUCTION: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 of each cycle. Treatment repeats repeat every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo disease assessment. Patients with a response complete 3 additional cycles of pembrolizumab, undergo disease assessment and proceed to consolidation. Patients without response or with progressive disease proceed to consolidation.

CONSOLIDATION: Patients receive doxorubicin IV, vinblastine IV and dacarbazine IV on days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for 2 to 6 cycles dependent upon response and disease type. Patients undergo echocardiography/ multigated acquisition (MUGA) scan, CT scan, PET scan and blood sample collection throughout the study and may undergo tumor biopsy during screening.

After completion of study treatment, patients are followed up at 30 days, every 3 months for 1 year, and every 6 months for 4 years.

• Patients of child-bearing potential (POCBP) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) from time of informed consent, for the duration of study participation, and for 120 days following completion of therapy. POCBP must not donate eggs as per timelines for use of contraception. Should a POCBP become pregnant or suspect they are pregnant while they or their partner is participating in this study, POCBP should inform their treating physician immediately.

NOTE: A POCBP is any person with an egg-producing reproductive tract (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

• Has not undergone a hysterectomy or bilateral oophorectomy

• Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)

• POCBP must have a negative pregnancy test within 7 days prior to registration on study NOTE: a negative urine pregnancy test is also required within 72 hours (3 days) prior to first dose of pembrolizumab and therefore may need to be repeated if screening test is more than 72 hours (3 days) prior to the first dose. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

• Patients must have the ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Diagnosis of nodular lymphocyte-predominant Hodgkin lymphoma

• Patients who have had prior systemic chemotherapy, radiation therapy, immunotherapy, or other systemic therapy (including investigational agents) for the treatment of cHL.

NOTE: If patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy. No radiation therapy for Hodgkin lymphoma (cHL) will be allowed prior to and while participation on this clinical trial, including for system control

• Patients who are actively participating in a clinical trial with an investigational agent or device or has participated in a clinical trial with an investigational agent or device within 30 days of the anticipated treatment start date.

NOTE: Patients who have entered the follow-up phase of an investigational study will be eligible to participate as long as = 30 days has elapsed since the administration of the last dose of an investigational treatment for a disease/condition other than cHL

• Patients who have known active central nervous system (CNS) metastases and/or lymphomatous meningitis are not eligible

• Patients who have any contraindication to the use of any of the chemotherapeutic agents used in this study

• Patients who have had an allogenic tissue or solid organ transplant

• Patients who are pregnant or nursing NOTE: Pregnant persons are excluded from this study because the chemotherapy regimen (AVD) includes adriamycin (also known as doxorubicin), which is an anthracycline; anthracyclines are known chemotherapy agents with the potential for teratogenic or abortifacient effects. In addition, the investigational agent, pembrolizumab, has the potential for embryo-fetal toxicity. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with adriamycin (doxorubicin) as part of the AVD chemotherapy regimen, and the investigational agent, pembrolizumab, breastfeeding should be discontinued if the mother is treated with AVD and/or pembrolizumab.

• Patients are not eligible who have a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator

• Patients who have known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial are not eligible

• Patients may not be pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial, from registration through 120 days after the last dose of trial treatment
