Abstract:

Background: BPI-7711 is a 3rd generation irreversible EGFR-TKI that is selectively against EGFR TKI–sensitizing mutations and the T790M resistance mutations. We are conducting a phase I study to determine the safety and efficacy of BPI-7711 in patients with advanced or recurrent EGFRm+/T790M+ NSCLC. Methods: NSCLC patients who had documented disease progression after 1st/2nd generation EGFR-TKI treatment and with EGFRm+/T790M+ confirmed by central lab were enrolled in the multicenter trial (NCT03386955) into “3+3” dose escalation or expansion cohorts. BPI-7711 was orally administered at doses of 30~240 mg in capsules. Patients in dose-escalation cohorts firstly received a single dose of BPI-7711 followed by a 7-day pharmacokinetic (PK) evaluation period then received the same dose daily until disease progression or intolerable toxicity(ies) per CTCAE V4.03. Treatment efficacy per RECIST 1.1 was evaluated every 6 weeks since daily treatment commence. Once efficacy was observed in a dose, its expansion cohort was opened to enroll patients for daily treatment. Results: As of 23 December 2018, 82 patients (median age 55, 27 males, 55 females) were enrolled into 5 dose escalation cohorts (30/60/120/180/240 mg) and 4 dose expansion cohorts (30/60/120/180 mg). No DLT was observed and MTD was not reached. For all safety-evaluable patients, most common treatment emergent adverse events (TEAEs) (≥10%) were white blood cell count decreased (21.3%), neutrophil count decreased (17.3%), upper respiratory tract infection (17.3%), vomiting (12.0%) and diarrhea (10.7%), and all were Grade 1 or 2. Grade 3~4 TEAEs were occurred in 8.0% patients and 4.0% of them were treatment-related per investigators’ judgement. SAEs were reported in 4.0% of patients, and 1.3% were treatment-related. For all efficacy-evaluable patients, the overall ORR of all doses was 54.5% (30/55) including 1.8% CR and 52.7% PR. The disease control rate (DCR) was 96.4%. For patients in 120/180 mg cohorts, the ORR was 64.1% (25/39) and DCR was 97.4%. PK analyses showed BPI-7711 exposure increased in a dose-proportional manner from 30 to 180 mg after single and multiple doses. Conclusions: BPI-7711 was well tolerated and highly effective in acquired T790M+ NSCLC patients. Phase II trials are under preparation. Clinical trial information: NCT03386955
