Additive toxicity arising from combined use of immune checkpoint inhibitors and tyrosine kinase inhibitors in patients with renal or endometrial carcinoma: Protocol for a rapid systematic review.

ABSTRACT

The combined use of immune checkpoint inhibitors and tyrosine kinase inhibitors (ICI/TKI) is an effective treatment strategy for some cancers. A better understanding of the potential additive toxicity for ICI/TKI combinations is needed to inform patient and provider treatment decisions. We aim to evaluate the safety of ICI/TKI combinations for individuals with renal cell or endometrial carcinoma. This rapid systematic review (SR) protocol follows PRISMA guidelines. A systematic search will be designed, peer reviewed and executed by experienced information specialists (Cochrane Central, MEDLINE, Embase) to identify published SRs and primary studies published since the most recent SR search. Randomized, quasi- or non-randomized controlled trials and comparative cohort studies are eligible if they compare ICI/TKI combinations to monotherapy or standard of care in participants with renal cell or endometrial carcinoma. The primary outcome is grade ≥ 3 treatment-related adverse-effects. Studies will be screened, selected, extracted and assessed for risk of bias by a single reviewer and checked completely by a second. Where feasible and appropriate, we will pool studies separately by design and indication using meta-analysis and test robustness of effects using prespecified subgroup and sensitivity analyses. Results will be summarized descriptively and presented in tables and figures. (PROSPERO ID CRD42023416388).•This will be a comprehensive systematic review of the additive toxicity arising from the combined use of ICI/TKIs in patients with renal-cell or endometrial carcinoma.•We will consider treatment-related, treatment-emergent adverse events (Grade 3 or higher).•Identified safety profile may be used to inform patient or provider treatment decisions.
