IDO and PD-L1 Peptide Based Immune-Modulatory Therapeutic (IO102-IO103) in Combination With Pembrolizumab for BCG-Unresponsive or Intolerant, Non-Muscle Invasive Bladder Cancer
Sponsor:

Brief Summary:

This phase I trial tests the safety and side effects of a PD-L1/IDO peptide vaccine (IO102-IO103) in combination with pembrolizumab in treating patients with non-muscle invasive bladder cancer. IO102-IO103 is a novel IDO and PD-L1 peptide based immune-modulatory therapeutic. It is designed to activate the patient's own immune cells (called T-cells) to fight the tumor and stop the tumor cells escaping from the body's immune system. IO102-IO103 works to directly kill tumor cells and remove the body's immune suppressive cells, which are cells that prevent the immune system from fighting the tumor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving IO102-IO103 in combination with pembrolizumab may make tumor cells more visible/recognizable to the immune system.

PHASE1

Detailed Description:

PRIMARY OBJECTIVE: I. Evaluate the feasibility, safety and toxicity of the PD-L1/IDO peptide vaccine (IO102-IO103) in combination with pembrolizumab in patients with Bacillus Calmette-Guerin (BCG)-unresponsive or intolerant, non-muscle invasive bladder cancer (NMIBC). SECONDARY OBJECTIVES: I. To assess preliminary efficacy of IO102-IO103 in combination with pembrolizumab. II. To obtain preliminary efficacy of IO102-IO103 in combination with pembrolizumab. OUTLINE: Patients receive PD-L1/IDO peptide vaccine subcutaneously (SC) and pembrolizumab intravenously (IV) on study. Patients also undergo computed tomography (CT) and/or CT/positron emission tomography (PET) and collection of blood samples throughout the trial.After completion of study treatment, patients are followed up for 30 days and then every 3 months thereafter.

Individuals on anticoagulant therapy should have a prothrombin time (PT) or partial thromboplastin time (PTT) within therapeutic range of intended use and no history of severe hemorrhage
  • * Ability to understand and willingness to sign an informed consent document
  • * Ability to adhere to the study visit schedule and other protocol requirements
  • * For female patients of childbearing potential and male patients with partners of childbearing potential, agreement (by patient and/or partner) to use methods of contraception
Exclusion Criteria
  • * Patients with a prior or concurrent malignancy whose natural history or treatment may, in the opinion of the investigator, have the potential to interfere with the safety or efficacy assessment of the investigational regimen
  • * Uncontrolled concomitant disease that in the opinion of the investigator would interfere with the patient's safety or compliance on trial
  • * Known history of positive test for human immunodeficiency virus (HIV) with CD4 \< 200 or acquired immunodeficiency syndrome (AIDS)-defining condition
  • * Known active tuberculosis
  • * Active infection requiring systemic therapy, including active or intractable urinary tract infection (UTI)
  • * Previous treatment with checkpoint inhibitors targeting either PD-(L)1 or CTLA-4
  • * Prior exposure to IO102 or IO103
  • * Received systemic chemotherapy, targeted small molecule therapy, or radiotherapy =\< 2 weeks before study treatment initiation
  • * Any adverse events from prior cancer therapy have resolved to grade =\< 1 according to Common Terminology Criteria for Adverse Events (CTCAE) version 5

  • * Any medical condition requiring systemic steroid equivalent to prednisone \> 10 mg daily or immunosuppressive therapy within 14 days or 5 half-lives prior to first dose of trial therapy. Patients with a history of autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone are eligible. Patients who have adrenal insufficiency and hypophysitis from prior immunotherapy if they are on stable medical replacement doses are eligible
  • * Received a live or live-attenuated vaccine =\< 30 days before the first dose of study treatment. Administration of killed vaccines, messenger ribonucleic acid (mRNA) based vaccines (e.g., COVID-19), and vector based vaccines are allowed
  • * Pregnant and/or breast feeding women. If a urine pregnancy test is positive or cannot be confirmed as negative, a serum pregnancy test will be required =\< 24 hours prior to planned treatment initiation

  • * Known allergy or reaction to any component of either study drug formulation
  • * Any condition that would prohibit the understanding or rendering of informed consent
