About
This is an open-label, parallel group, non-randomized, multicenter phase II study to evaluate the efficacy of spartalizumab (cohorts 1 and 2) and tislelizumab (cohort 3) in monotherapy in patients with PD1-high-expressing tumors.
Full description
Patients will sign a molecular pre-screening consent form across centers in Spain that will allow determination of PD1 mRNA expression on a tumor sample using the nCounter-based technology. This will be centrally performed at Hospital Clinic of Barcelona.
In this trial, three patient cohorts are planned:

Inclusion criteria
Exclusion criteria
A Women of childbearing potential who has a positive urine pregnancy test within 72 hours prior to allocation. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Note: in the event that 72 hours have elapsed between the screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative in order for subject to start receiving study medication.
Has received prior therapy with an anti-PD1, anti-PDL1, or anti-PDL2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor.
Has received prior systemic anti-cancer therapy, including investigational agents within 2 weeks. Medical Monitor could consider shorter interval for kinase inhibitors or other short half-life drugs prior to allocation.
Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline according to CTCAE version 5.0 (except alopecia). 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 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.
Use of any live vaccines against infectious diseases within 4 weeks of initiation of study treatment.
Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 2 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 2 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.
Patients with thymoma are not eligible. Patients with active CNS metastases and/or carcinomatous meningitis are not eligible. Subjects with up to three cerebral metastases are eligible, if all lesions are stable and have been definitively treated with stereotactic radiation therapy, surgery or gamma knife therapy with no evidence of disease 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 severe hypersensitivity (≥Grade 3) to Spartalizumab or Tislelizumab and/or any of its excipients.
History of severe hypersensitivity reactions to other monoclonal antibodies, which in the opinion of the investigator may pose an increased risk of serious infusion reaction.
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.
Prior allogeneic stem cell transplantation or organ transplantation
Has a history of interstitial lung disease, (non-infectious) pneumonitis that required steroids or has current pneumonitis, uncontrolled lung including pulmonary fibrosis, acute lung diseases, etc. Patients with significantly impaired pulmonary function, or who require supplemental oxygen at baseline must undergo an assessment of pulmonary function at screening.
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 is detected) infection.
Has a known history of active TBC (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 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 or father children within the projected duration of the study, starting with the screening visit through 150 days after the last dose of trial treatment.
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 150-days after stopping treatment with spartalizumab or tislelizumab. Highly effective contraception methods include:
Notes:
Sexually active males, unless they use a condom during intercourse while on treatment and for 150 days after stopping treatment with spartalizumab or tislelizumab should not father a child in this period. A condom is required to be used by vasectomized men as well during intercourse in order to prevent delivery of the drug via semen.
