Study Details

Study Description

Brief Summary

This study will evaluate the use of siltuximab to decrease the severity of cytokine release syndrome (CRS) and immune effector cell-associated neurological syndrome (ICANS) in patients who will receive chimeric antigen receptor (CAR) T-cell therapy for the treatment of hematological malignancies.

Condition or Disease	Intervention/Treatment	Phase
Cytokine Release Syndrome ICANS Lymphoma, Non-Hodgkin Multiple Myeloma Acute Lymphoblastic Leukemia	Drug: Siltuximab	Phase 2

Detailed Description

Patients eligible to receive CAR T-cell therapy for FDA-approved indications in hematological malignancies will be enrolled in this study on the day of CAR T-cell infusion. Patients will be followed until they develop grade 1 or higher CRS and/or ICANS. On developing these syndromes, siltuximab will be administered with close monitoring and follow-up for resolution of symptoms. If symptoms continue to worsen, then an additional dose of siltuximab will be given. If the symptoms leading to CRS do not resolve, then rescue tocilizumab will be administered. The study's primary endpoint is to assess the response rate of siltuximab in the resolution of CRS within 14 days. The study's secondary endpoint is to assess the response rate of siltuximab in the resolution of ICANS, the safety of siltuximab, and the overall response rate of CAR T-cell therapy.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Siltuximab Patients who experience CRS/ICANS will receive this treatment	Drug: Siltuximab Siltuximab is administered at the dose of 11mg/kg via intravenous infusion over 1 hour. If no resolution of CRS is achieved then a repeat dose of siltuximab at the dose of 11mg/kg via intravenous infusion over 1 hour will be given.

Arm

Intervention/Treatment

Experimental: Siltuximab

Patients who experience CRS/ICANS will receive this treatment

Drug: Siltuximab

Siltuximab is administered at the dose of 11mg/kg via intravenous infusion over 1 hour. If no resolution of CRS is achieved then a repeat dose of siltuximab at the dose of 11mg/kg via intravenous infusion over 1 hour will be given.

Outcome Measures

Primary Outcome Measures

Participants with a complete response for cytokine release syndrome (CRS) [Baseline through 14 days]
Participants who achieve a resolution of CRS. Resolution of CRS is defined as absence of symptoms leading to diagnosis of CRS for 24 hours.

Secondary Outcome Measures

Participants with a response for Immune effector Cell Associated Neurotoxicity Syndrome (ICANS) [Baseline through 28 days]
Participants who achieve a resolution or improvement in their ICANS. Complete response or partial response for ICANS is defined as either complete disappearance or decrease in the grade of severity as measured by ASTCT Consensus Grading for ICANS. The ASTCT grade is from 1 to 5 for ICANS with 1 being mild symptoms and 5 being severe symptoms.
Participants experiencing adverse events from Siltuximab [Baseline through 28 days]
All Adverse Events (AE's) will be reported and evaluated using National Cancer Institute's Common Terminology Criteria (CTCAE) v5.0.
Participants with response to CAR T-cell therapy [Baseline through day 90]
This will be measured by using specific criteria's for Lymphoma, Multiple Myeloma or Acute Lymphoblastic Leukemia (ALL) [Based on the patients diagnosis]
