Изучение комбинации пембролизумаба с химиотерапией при чувствительном к платине рецидивирующем низкодифференцированном серозном раке яичников (PERCEPTION)

Inclusion Criteria:

• Female, age at least 18 years.
• Histologically diagnosed low-grade serous ovarian cancer, fallopian tube cancer, or primary peritoneal cancer.
• Patients must have completed at least 1 previous course of platinum-containing therapy (e.g., combination with carboplatin or cisplatin. Maintenance therapy with bevacizumab and/or endocrine agents is allowed).
• Progression or recurrence after platinum-containing therapy, occurring no sooner than 6 months after completion of the last dose of platinum chemotherapy (platinum sensitive disease).
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
• Women of childbearing potential should not become pregnant while on the Product and should not be pregnant at the beginning of treatment. A pregnancy test should be performed on all women of childbearing potential prior to receiving the Product. Women of childbearing potential must agree to follow contraceptive guidance during the treatment period and for 6 months after receiving the last dose of the study therapy.
• The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
• Availability of archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.

Exclusion Criteria:

• High-grade ovarian cancer.
• Persistent ≥Grade 2 hematologic toxicity from prior cancer therapy Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy may be eligible.

Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.

• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX 40, CD137).
• Is eligible for carboplatin-based doublet therapy in combination with bevacizumab in the relapse situation, since no treatment with bevacizumab has been administered in the first line therapy.
• Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks.
• Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
• Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.
• Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.

Note: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.

• Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
• Has a known additional malignancy that is progressing or has required active treatment within the past 3 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
• Has known active CNS metastases and/or carcinomatous meningitis. Participants 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 (note that the 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.
• Has a bleeding tumor
• Has hypersensitivity to any of the study drugs the patient will be treated with and/or to any of the excipients of the study drugs the patient will be treated with.
• Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). 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.
• Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
• Has an active infection requiring systemic therapy.
• Has a known history of Human Immunodeficiency Virus (HIV).
• Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] has been detected) infection.
• Has a known history of active TB (Bacillus Tuberculosis).
• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
• Has had an allogenic tissue/ solid organ transplant.
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• Is pregnant or breastfeeding, or expecting to conceive within the projected duration of the study, starting with the screening visit through 6 months after the last dose of trial treatment.
• Patients unable to be regularly followed for any reason (geographic, familiar, social, psychologic, housed in an institution e.g. prison because of a court agreement or administrative order).
• Subjects that are depending on the sponsor/CRO or investigational site as well as on the investigator.
