Abstract 1423


The next-generation ALK inhibitor BRG has shown activity in ALK+ NSCLC patients (pts) in clinical trials.


Pts with advanced malignancies (N = 137; including 79 pts with ALK+ NSCLC) received oral BRG (30–300 mg/d) in a phase 1/2, open-label, multicenter trial (NCT01449461). We report activity by RECIST v1.1 in ALK+ NSCLC pts and safety in all pts, with long-term follow-up (>31 months since last pt was enrolled).


Among 79 ALK+ NSCLC pts, median age was 54 years; 90% (71/79) had received prior crizotinib (CRZ). As of 21 Feb 2017, 32% of ALK+ NSCLC pts (25/79) and 25% (7/28) of those receiving 180 mg qd with a 7-day lead-in at 90 mg (a regimen evaluated in the phase 2 portion of the trial) continued to receive BRG. Median treatment duration was 20.0 months (1 day to 56.1 months). Confirmed objective response rate (ORR) was 63% (45/71) in pts with prior CRZ and 100% (8/8) in CRZ-naive pts. Additional efficacy data are shown in the table. At 180 mg qd (with lead-in), confirmed ORR was 76% (95% CI, 55%–91%) and median progression-free survival (PFS) was 16.3 months (95% CI, 9.2–28.1) in pts with prior CRZ. Treatment-emergent adverse events (AEs) in ≥ 30% of all 137 pts, mostly grade 1/2, were nausea (55%), fatigue (45%), diarrhea (42%), headache (36%), and cough (34%). Grade ≥3 treatment-emergent AEs in ≥ 5% of pts were increased lipase (12%), pneumonia (7%), dyspnea (6%), and hypertension (6%). Eleven percent of pts (15/137) discontinued BRG due to an AE.


BRG shows major antitumor activity in ALK+ NSCLC pts with an acceptable safety profile in this long-term follow-up. PFS of > 16 months in pts receiving 180 mg qd with a 7-day lead-in at 90 mg is among the longest reported in CRZ-resistant ALK+ NSCLC. This dosing regimen is being investigated in a randomized phase 3 trial of BRG vs CRZ in ALK inhibitor–naive pts with advanced ALK+ NSCLC (ALTA-1L; currently recruiting pts).Table:
