In the AVOREN trial, first-line BEV + IFN (9 MIU three times in a week [tiw]) was effective in patients (pts) with mRCC. A retrospective analysis found that efficacy was maintained and IFN-related toxicity was improved in pts with IFN dose reduced to 6 or 3 MIU. BEVLiN (MO21609) prospectively assesses the safety and efficacy of BEV with low-dose IFN (3 MIU) in mRCC.


BEVLiN is an open-label single arm, multinational phase 2 study. Nephrectomized, treatment-naive pts with clear cell mRCC and favourable/intermediate Motzer scores were treated with BEV 10mg/kg q2w + IFN 3 MIU tiw until disease progression. BEVLiN was designed to allow descriptive, cross-trial comparison with the BEV + IFN 9 MIU-treated favourable/intermediate Motzer score AVOREN subgroup. Primary end points are safety (specific grade [Gr] ≥3 IFN-associated adverse events [AEs]) and progression-free survival (PFS). Secondary end points are overall survival (OS); overall response rate (ORR); any Gr ≥3, overall, and serious AEs.


147 pts were enrolled in BEVLiN. Baseline pt characteristics were similar to the comparator AVOREN subgroup. The median follow-up was 29.4 months. Pts received a median of 22.5 cycles of BEV (18.0 in the AVOREN subgroup). Median PFS was 15.3 mos (95% CI: 11.7; 18.0) vs 10.5 mos (95% CI: 10.1; 12.9); median OS was 30.7 mos (95% CI: 25.7; not reached) vs 25.8 mos (95% CI: 22.7; 29.4); and ORR was 29% vs 36% in BEVLiN and the AVOREN subgroup, respectively. The rates of any-Gr and Gr ≥3 IFN-associated AEs were markedly lower in BEVLiN than in the AVOREN subgroup (Table). Overall rates of AEs of special interest were similar between studies, despite longer BEV duration in BEVLiN.

Use of low-dose IFN with BEV in BEVLiN resulted in a reduction in IFN-related AEs without compromising efficacy outcomes compared with a control AVOREN subgroup.
