A Phase II Study of the Combination of Pembrolizumab and ATRA Combination Treatment of Relapsed HL and B-NHL (NCT06484920)

Usually NOT eligible if any of the following apply:

• Exclusion Criteria:
• Patients currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
• Known brain metastases and/or leptomeningeal disease. Subjects with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.
• Significant reduction in ECOG performance status between the screening/ baseline visit and within 72 hours prior to commencement of treatment as per trial protocol, as per the Investigator's assessment, defined as a reduction in ECOG score to 3 or 4.
• Patients with a diagnosis of immunodeficiency or receiving systemic steroid therapy or any other form of immunosuppressive therapy (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs) within 7 days prior to the first dose of trial treatment. 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.
• Hypersensitivity to pembrolizumab or any of its excipients.
• Contraindication to the use of ATRA including but not limited to: patients with a history of hypersensitivity reaction to tretinoin, vesanoid or related compounds ( i.e. acitretin, isotretinoin, vitamin A); , Tetracyclines, Progesterone (low dose), drugs inducing P450 (rifampicin, glucocorticoids, phenobarbital, etc), ketoconazole and drugs inhibiting p450 (cimetidine, erythromycin, cyclosporine, etc); antifibrinolytic agents (e.g. tranexamic acid, aminocaproic acid, aprotinin) and hydroxyurea)
• Prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day -1 or who have not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
• Prior chemotherapy targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day -1 or who have not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. Subjects with chronic conditions such as vision changes or prior hearing loss that is not reasonably expected to be exacerbated by the investigational product may be included. Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study. Note: Subjects with Grade 2 adrenal insufficiency or thyroid conditions who are not expected to resolve to baseline, are on a stable dose of medication may be included if it is not reasonably expected to be exacerbated by the investigational product, and asymptomatic whilst on treatment.
• History of malignancy in the last 5 years with the exception of prior history of in situ cancer or basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy, or in situ cervical cancer. Patients with other malignancies are eligible if they were cured by surgery alone or surgery plus radiotherapy and have been continuously disease-free for at least 5 years.
• Patient has undergone major surgery, other than diagnostic surgery (i.e., surgery done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day -1 of treatment in this study. Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
• Known history of, or any evidence of active, non-infectious pneumonitis.
