Who can join

Age: 65 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically confirmed diagnosis of de novo classical Hodgkin Lymphoma (cHL). Note: Availability of either block or unstained slides plus stained slides used by the local pathologist to make diagnosis, and of all pathology reports is mandatory for the study to perform central pathology review for confirmation of cHL diagnosis and for biological biomarkers assessments. Central pathology confirmation is not required to start treatment;
• Patients >= 65 years ineligible for frontline standard chemotherapy (mainly due to medical comorbidities);
• Treatment naïve;
• Measurable disease defined as presence of both fluorodeoxyglucose-avid nodal involvement and at least one nodal target lesion measurable in two diameters (and at least 1.5 cm in its major diameter); • Indication for systemic treatment, i.e., all stages except IA without a large tumor burden, as radiotherapy is regarded curative in those patients;
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) <= 2;
• Adequate organ and marrow function as defined below:
• Absolute neutrophil count (ANC) > 109/L (without growth factor support within 7 days of ANC measurement), unless due to bone marrow involvement by lymphoma
• Platelet > 50 x 109/L (without growth factor support or transfusion within 7 days of platelets measurement) , unless due to bone marrow involvement by lymphoma
• Hemoglobin > 8 g/dL (prior transfusion is acceptable)
• Creatinine clearance ≥ 30 ml/min (as estimated by the Cockcroft-Gault equation or as measured by nuclear medicine scan or 24-hour urine collection)
• Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase, and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase ≤ 3.0 × upper limit of normal (ULN)
• Serum total bilirubin < 1.5 × ULN (or < 3 x ULN in case of documented Gilbert's syndrome)
• Life expectancy ≥ 6 months;
• Men must agree to use effective contraception if sexually active. This applies for the time period between signing of the informed consent form and 4 months after last tislelizumab dose. The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control method, e.g. vasectomy, use of condoms or complete sexual abstinence, when this is in line with the preferred and usual lifestyle of the subject.The use of condoms by male patients is required unless the female partner is permanently sterile. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods for the female partner) and withdrawal are not acceptable methods of contraception.
• Subject voluntarily signs and dates an informed consent form approved by an National Ethics Committee (NEC) prior to the initiation of any screening or study-specific procedures, indicating that they understand the purpose of and procedures required for the study and are willing to participate in it;
• Subject must be able to adhere to the study visit schedule and other protocol requirements, and to return to enrolling institution for follow-up (during the active monitoring phase of the study).

You may not qualify if…

• Nodular lymphocyte predominant HL;
• Any previous treatment (including radiation therapy) for HL;
• Any active autoimmune disease requiring systemic treatment (including disease-modifying agents, corticosteroids, immunosuppressants) in the past 2 years; Note: Patients with the following diseases are not excluded and may proceed to further screening: Type I diabetes under control; Hypothyroidism (provided it is managed with hormone replacement therapy only); Controlled celiac disease;
• Has known history of interstitial lung disease, non-infectious pneumonitis, pulmonary fibrosis, acute lung diseases or evidence of dyspnea at rest or pulse oximetry of < 92% while breathing room air;
• A history of previous exposure to anti-PD1, anti-PDL1 or anti-PDL2 or anti-CTLA-4 agents for any disease other than HL;
• Use of systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications ≤14 days from registration; Note: Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease;
• Known infection with HIV, human T-cell lymphotropic virus-1, -2; • Serologic status reflecting active hepatitis B defined as presence of hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) (mandatory testing). Patients with occult or prior HBV infection (respectively defined as patient with HBsAg-/HBcAb+ and patients HBsAg+ with HBV DNA undetectable) are eligible, provided that they are willing to undergo prophylactic antiviral medication according to local standard of care. Patients who have protective titers of hepatitis B surface antibody (HBsAb) after vaccination are eligible;
• Presence of hepatitis C virus (HCV) antibody (mandatory HCV antibody serology testing). Patients with presence of HCV antibody are eligible only if PCR is negative for HCV RNA;
• Hypersensitivity to tislelizumab or any of its excipients;
• Active central nervous system (CNS) involvement or leptomeningeal metastases involvement;
• Evidence of other clinically significant uncontrolled and/or active systemic infection (viral, bacterial or fungal), including active ongoing infection from SARS-CoV-2;
• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens;
• Major surgery within 4 weeks of the first dose of study drug;
• Vaccination with a live vaccine within 4 weeks prior to the first dose of study drug;
• Clinically significant cardiovascular disease including the following:
• Myocardial infarction within 6 months before screening;
• Unstable angina within 3 months before screening;
• New York Heart Association Classification III or IV congestive heart failure;
• History of clinically significant arrhythmias (e.g., sustained ventricular tachycardia, ventricular fibrillation, torsade de pointes);
• QTcF > 480 msecs based on Fridericia's formula;
• History of Mobitz II second-degree or third-degree heart block without a permanent pacemaker in place;
• Uncontrolled hypertension as indicated by a minimum of 2 consecutive blood pressure measurements showing systolic blood pressure > 170 mm Hg and diastolic blood pressure > 105 mm Hg at screening;
• Significant history of neurologic, psychiatric, endocrinological, metabolic, immunologic, or hepatic disease that would preclude participation in the study or compromise ability to give informed consent;
• Any history of other active malignancies within 3 years prior to study entry, with the exception of adequately treated in situ carcinoma of the cervix uterine, basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin, previous malignancy confined and surgically resected with curative intent;
• History of severe hypersensitivity reactions to other monoclonal antibodies;
