To be eligible for this trial, patients should be class 2B or better
• 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 from study treatment initiation and for 120 days after completion of treatment on study. 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) NOTE: After consultation with the principal investigator, start of treatment may be delayed for patients completing fertility preservation

PWSPRC treated or enrolled on this protocol must also agree to refrain from donating sperm, from time of informed consent, for the duration of study participation, and for 120 days following completion of therapy
• 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 a history of allergic reactions attributed to compounds of similar chemical or biologic composition to pembrolizumab, and/or any of its excipients
• 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 who have a diagnosis of immunodeficiency or are receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to registration are not eligible. NOTE: Replacement therapy (e.g., thyroxine, insulin, physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed
• Patients who have a known history of active TB (Bacillus Tuberculosis) are not eligible
• Patients who have an uncontrolled intercurrent illness including, but not limited to any of the following, are not eligible: * Symptomatic congestive heart failure (ejection fraction lower than institutional lower limit of normal [LLN] * Unstable angina pectoris * Cardiac arrhythmia
• Patients who have any prior malignancy OR a known additional malignancy that is progressing or requires active treatment are not eligible. NOTE: Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer. Participants with low-risk early-stage prostate cancer (T1-T2a, Gleason score ≤ 6, and PSA < 10 ng/mL) either treated with definitive intent or untreated in active surveillance with stable disease are not excluded
• Patients who have active autoimmune disease that has required systemic treatment in the past 2 years are not eligible (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs) NOTE: Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed

• Patients who have an active infection requiring systemic therapy are not eligible, except for uncomplicated urinary tract infections
• 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
• Patients who have received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4, anti-OX-40 or anti-LAG-3 agent are not eligible
