Background: Recent results from COSMIC 313 trial and updated findings from other contemporary trials have added to the existing body of evidence for 1L mRCC. Therefore, we present the most up-to-date results from our living, interactive systematic review (LISR) to facilitate the choice of optimal therapy in 1L mRCC setting. Methods: This LISR and network meta-analysis is maintained using a novel living evidence synthesis (LIvE) framework. The framework facilitates the identification of new or updated studies using an automated ‘living’ search which is followed by screening and extraction in a semi-automated fashion within a machine learning assisted graphical user interface. Relevant data is parsed and analyzed to compute mixed treatment comparisons and certainty of evidence is adjudicated using a rule-based algorithm. Detailed methods have been published before (PMID: 33824031). Results: As of October 1st 2022, this LISR includes 16 clinical trials (30 references). Mixed treatment comparisons showed statistically significant PFS benefit with lenvatinib-pembrolizumab (LenPem; rank 1) when compared to cabozantinib-nivolumab (CabNivo; rank 3; hazard ratio [HR]: 0.69, 95% confidence interval: 0.52-0.93), CaboNivo-ipilimumab (CaboNivoIpi; rank 4; HR: 0.62; 0.43-0.89), avelumab-axitinib (AveAxi; rank 5; HR: 0.56; 0.43-0.75), PemAxi (rank 6; HR: 0.55; 0.42-0.72), atezolizumab-bevacizumab (AteBev; rank 7; HR: 0.46; 0.35-0.59), and NivoIpi (rank 8; HR: 0.45; 0.35-0.59). No significant differences were observed between CaboNivoIpi and other combination therapies for PFS improvement. Similarly, for OS, LenPem (rank 1), PemAxi (rank 2) and CaboNivo (rank 3) were ranked as potentially more efficacious treatment options than other counterparts. However, no statistically significant difference was observed for OS benefit with mixed treatment comparisons. The odds of achieving an ORR were higher with LenPem (rank 1; odds ratio [OR]: 2.44; 1.43-4.17), and CaboNivo (rank 2; OR: 1.77; 1.04-3.03) when compared to CaboNivoIpi (rank 6). NivoIpi (rank 1), LenPem (rank 2), CaboNivoIpi (rank 3) were ranked potentially as more efficacious treatments for achieving a CR. In terms of grade 3 or higher treatment related adverse events, NivoIpi (rank 3) was ranked as potentially the safest option among other combinations while CaboNivoIpi (rank 12), LenPem (rank 11), and CaboNivo (rank 10) were more likely to increase the risk of toxicity compared to most other treatments. Conclusions: Triplet combination of CaboNivoIpi may not provide additional survival benefit compared to other immunotherapy combinations and may increase toxicity. Patient-level considerations such as treatment toxicity, and quality of life should be factored in when opting intensified 1L therapies in mRCC patients.
