Spots Global Cancer Trial Database for CD24Fc for the Treatment of Immune Related Adverse Events in Patients With Advanced Solid Tumors, TIRAEC Study

Study Description

Brief Summary: This phase I/II trial investigates the side effects and how well CD24Fc works in treating immune related adverse events in patients with solid tumors that have spread to other places in the body (advanced). CD24Fc may prevent autoimmune reactions due to the tissue damage induced by cancer treatment. CD24Fc binds to injured cell components and prevents inflammatory responses. CD24Fc also acts to turn off the immune system after it has been activated ("immune checkpoint"). Adding CD24Fc to standard treatment may shorten the recovery time and reduce the severity of side effects from immunotherapy.

Detailed Description: PRIMARY OBJECTIVES: I. To determine the safety and tolerability of CD24 extracellular domain-IgG1 Fc domain recombinant fusion protein CD24Fc (CD24Fc) in patients with advanced solid tumors who developed debilitating immune-related adverse events (irAEs) from immune check point inhibitors (ICIs). (Phase I) II. To determine if CD24Fc shortens the recovery time of irAE and increases the recovery rate of irAE in cancer patients with grade (G)2 or 3 irAEs. (Randomized phase II) SECONDARY OBJECTIVES: I. Time to irAE reduction by at least 1 grade. (Phase I) II. Time to all irAEs reduced to grade =\< 1. (Phase I) III. Time to resume ICI treatment. (Phase I) IV. Recovery rate (as defined by reduction of irAE by one grade) at day (D)42. (Phase I) V. To estimate the time to all irAEs reduced to =\< 1. (Randomized phase II) VI. To record the use of steroids (drug, dose, duration) and other treatment for irAE. (Randomized phase II) VII. To record the time to resume ICI treatment. (Randomized phase II) VIII. To estimate the preliminary overall response rate (ORR), progression free survival (PFS), and 1-year overall survival (OS) after treatment with or without CD24Fc. (Randomized phase II) IX. To determine if CD24Fc treatment changes the levels of inflammatory markers in the plasma. (Randomized phase II) OUTLINE: PHASE I: Patients receive CD24Fc intravenously (IV) over 60 minutes on days 1, 14, and 28 with standard of care (i.e., steroids per treating physician and best supportive care) in the absence of disease progression or unacceptable toxicity. PHASE II: Patients are randomized to 1 of 2 arms. ARM I: Patients receive CD24Fc IV over 60 minutes on days 1, 14, and 28 in addition to standard of care treatment for irAE in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive placebo IV over 60 minutes on days 1, 14, and 28 in addition to standard of care treatment for irAE in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at days 42 and 60 and then every 3 months for up to 1 year.
