Study Description

Brief Summary:

The purpose of this study is to find out whether IMPRINT in combination with pembrolizumab is a safe treatment for people with malignant pleural mesothelioma (MPM).The highest dose of IMPRINT that causes few or mild side effects when given in combination with pembrolizumab will be found. Once the highest safe dose of IMPRINT is found, it will be tested in combination with pembrolizumab in future participants to see whether the combination may be an effective treatment for MPM.

Arms and Interventions

Intervention/treatment

Experimental: Participants with malignant pleural mesothelioma (MPM); Participants will be diagnosed with malignant pleural mesothelioma and be deemed unresectable per thoracic surgeon assessment

Drug: Pembrolizumab; Fixed dose of pembrolizumab 200mg IV q3 weeks; Radiation: IMPRINT; The starting radiation dose will consist of 400cGy x5 fractions. Doses will be escalated by 100cGy per fraction (i.e. 400cGy, 500cGy, 600cGy) for a total of 3 dose levels. The MTD will be evaluated using a modified Continuous Reassessment Method. Dose limiting toxicities (DLTs) are defined as any treatment-related non-hematologic toxicity with a CTCAE v5 Grade ≥3 or grade ≥2 pneumonitis that requires use of steroids occurring after the start of IMPRINT through the first 3 months after the last fraction.; Other Name: intensity-modulated pleural radiation therapy

Outcome Measures

Primary Outcome Measures :

1. Maximum Tolerated Dose (MTD) of IMPRINT [ Time Frame: 6 months ]
   The first primary objective of this study is to determine the MTD of IMPRINT among the three candidate doses: 400cGy x5 fractions, 500cGy x5 fractions and 600cGy x5 fractions. These dose levels will be evaluated using a modified Continuous Reassessment Method (CRM) starting with the lowest dose level 400cGy x5 fractions. Determined by the first 12 participants enrolled to the study.

• PFTs: DLCO >40% predicted, FEV1 >50% predicted
• Male/female participants who are at least 18 years of age on the day of signing informed consent

Male participants:

• A male participant must agree to use a contraception as detailed in Appendix 1 of this protocol during the treatment period and for at least 30 days, corresponding to time needed to eliminate any study treatment(s) (pembrolizumab and or any active comparator/combination) plus an additional 120 days (a spermatogenesis cycle) for study treatments with evidence of genotoxicity at any dose after the last dose of study treatment and refrain from donating sperm during this period.

Female participants:

• A female participant is eligible to participate if she is not pregnant (see Appendix 1), not breastfeeding, and at least one of the following conditions applies:

  1. Not a woman of childbearing potential (WOCBP) as defined in Appendix 1 OR
  2. A WOCBP who agrees to follow the contraceptive guidance in Appendix 1 during the treatment period and for at least 120 days (corresponding to time needed to eliminate any study treatment(s) (pembrolizumab and or any active comparator/combination) plus 30 days (a menstruation cycle) for study treatments with risk of genotoxicity after the last dose of study treatment.
• The participant (or legally authorized representative if applicable) provides written informed consent for the trial.
• Have a ECOG performance status of 0 to 1. Evaluation of ECOG is to be performed within 30 days prior to the date of allocation.
• Have adequate organ function as defined in the following table (Table 1). Specimens must be collected within 45 days prior to the start of study treatment.

Table 1: Adequate Organ Function Laboratory Values

System: Hematological Absolute neutrophil count (ANC) ≥ 1.5 K/mcL Platelets ≥ 100 K/mcL Hemoglobin ≥ 9.0 g/dL

System: Renal Creatinine OR Measured or calculated^b creatinine clearance (GFR can also be used in place of creatinine or CrCl): ≤ 1.5 x ULN OR ≥ 30 mL/min for participant with creatinine levels >1.5 x institutional ULN

System: Hepatic Total bilirubin: ≤ 1.5 x ULN OR direct bilirubin ≤ ULN for participants with total bilirubin levels >1.5 x ULN AST (SGOT) and ALT (SGPT): ≤ 2.5 x ULN (≤ 5 x ULN for participants with liver metastases)

ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase); AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase); GFR=glomerular filtration rate; ULN=upper limit of normal. Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.

^b: Creatinine clearance (CrCl) should be calculated per institutional standard.

Note: This table includes eligibility-defining laboratory value requirements for treatment; laboratory value requirements should be adapted according to local regulations and guidelines for the administration of specific chemotherapies.

Exclusion Criteria:

• Newly diagnosed MPM
• Prior thoracic radiation therapy or intrapleural therapy
• Bulky disease in the fissure preventing IMPRINT
• Evidence of distant metastatic disease
• Serious infection, concurrent active malignancies, or other serious medical illness

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.
• 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 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. Low grade malignancies not requiring active treatment 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, 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 pembrolizumab and/or any of its excipients.
• 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.
• Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
• 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] is 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 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 120 days after the last dose of trial treatment.
