OT-101 in Combination With Pembrolizumab in Subjects With Malignant Pleural Mesothelioma Failing to Respond to Checkpoint Inhibition

Exclusion Criteria

• •1. A WOCBP who has a positive urine pregnancy test within 72 hours prior to agent administration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• •2. Has received prior systemic anti-cancer therapy including investigational agents within 28 days prior to study therapy.
• •3. Has received prior radiotherapy within 2 weeks of start of study intervention. Participants must have recovered from all radiation-related toxicities and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
• •4. 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 (eg, FluMist®) are live attenuated vaccines and are not allowed.
• •5. 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. The following are exceptions to this criterion:
• •* Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
• •* Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
• •* Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
• •6. Has a history of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years.
• •7. 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 10 days prior to first dose of study intervention.
• •8. Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
• •9. 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 (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed.
• •10. Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
• •11. Has an active infection requiring systemic therapy.
• •12. 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 \[qualitative\] is detected) infection.
• •13. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
• •14. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• •15. Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment.
• •16. Has had an allogenic tissue/solid organ transplant.
