Trial to Evaluate irAEs With Different Standard of Care Dosing Strategies of Standard of Care Immunotherapies

A Late Phase Randomized Open-Label Multi Cohort Trial to Evaluate irAEs With Different Standard of Care Dosing Strategies of Standard of Care Immunotherapies

Sponsor

University of Kansas Medical Center

Enrollment

192 participants

Start Date

Oct 7, 2025

Study Type

INTERVENTIONAL

Conditions

Solid Tumor Malignancies

Summary

Phase 3/4 open label, randomized two cohort study (2 arms in each cohort). It is hypothesized that for people with a histologically or cytologically confirmed diagnosis of malignancy, the higher dose immunotherapy (every 6 weeks Pembrolizumab 400mg dose and every 4 weeks Nivolumab 480mg dose) has more immune-related adverse events irAEs compared to lower dose (every 3 weeks Pembrolizumab 200mg dose and every 2 weeks Nivolumab 240mg dose).

Eligibility

Min Age: 18 Years

Inclusion Criteria9

Ability of participant to understand this study, and participant willingness to sign a written informed consent.
Males and females age ≥ 18 years
ECOG Performance Status (PS) 0 - 2 (Appendix A.)
Females of childbearing potential must have a negative urine pregnancy test 72 hours prior to initiating treatment.
Histologically or cytologically confirmed diagnosis of solid tumor malignancy
Eligible to receive pembrolizumab or nivolumab based therapy
Any disease setting (neoadjuvant, adjuvant, unresectable, metastatic) or any line of therapy is allowed. NOTE: Standard of care combination agents(chemotherapy, targeted therapy, biologics) are allowed because irAEs are the primary objective
Adequate organ function, defined as follows:
Leukocytes (White Blood Cell \[WBC\]) >1.0 K/UL Absolute Neutrophil Count >1.0 K/UL Platelets > 50 K/UL Hemoglobin ≥ 7 g/dL Serum creatinine ≤ 1.5 x upper limit of normal (ULN) or calculated creatinine clearance ≥ 50 mL/min using the Cockcroft-Gault equation Total bilirubin ≤ 1.5 x ULN Aspartate aminotransferase and alanine aminotransferase ≤ 2.5 x ULN unless liver metastases are present, in which case they must be ≤ 5 x ULN

Exclusion Criteria7

Simultaneously enrolled in any therapeutic clinical trial
Concurrent or planned use of other immunotherapies or radiation
Has not recovered from irAEs due to prior immunotherapy treatment (>=grade 2 is considered not recovered). Conditions that meet grade 2 criteria but are considered clinically stable at the discretion of the investigator will be allowed.
Diagnosed with a psychiatric illness or is in a social situation that would limit compliance with study requirements
Currently pregnant or breastfeeding
Has a known allergic reaction to any excipient contained in the study drug formulation
Active Grade 3 (per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0 ) or higher viral, bacterial, or fungal infection within 2 weeks prior to the first dose of study treatment.
