Abstract

Background

Mobocertinib is a first-in-class, potent, oral, irreversible tyrosine kinase inhibitor that selectively targets in-frame EGFRex20ins mutations in NSCLC. It was recently approved in the US (Sep-2021) and the UK (Mar-2022) for patients with locally advanced or metastatic NSCLC (aNSCLC) with EGFRex20ins mutations whose disease has progressed on platinum-based chemotherapy. This report describes the real-world treatment duration of mobocertinib in post-platinum EGFRexon20ins aNSCLC patients enrolled in a global EAP that provides access to mobocertinib for patients with unmet medical need.

Methods

Demographics were collected at screening. Treatment start/stop dates were estimated from shipped orders of mobocertinib. A standard shipment included a 90-day supply. Treatment discontinuation was physician-reported or assumed based on no re-orders for 120 days after the last shipment. Patients who had not discontinued treatment were censored on the date of data extraction. Time-to-treatment discontinuation (TTD) and probability of continued treatment at 6 and 12 months were estimated using Kaplan-Meier analysis.

Results

There were 556 eligible patients enrolled in the EAP between Jun-2020 and Dec-2021: 60.8% were female, median age was 62 years, and 58.1% reported ≥2 previous lines of therapy (LOT). Most patients were from Europe (47.5%) or Asia-Pacific (36.3%). Median TTD (95% CI) was 5.3 months (4.4, 6.3). Probability of continued treatment at 6 and 12 months was 48% and 32%, respectively. In patients with 1 previous LOT (n = 233) median TTD was 5.6 months (4.0, 9.0); in patients with ≥2 previous LOTs (n = 287) it was 4.8 months (4.0, 6.3). Among the 287 patients with ≥2 orders of mobocertinib (51.6%), TTD was 11.6 (8.9, 12.6) months with a 69% and 46% probability of continued treatment at 6 and 12 months, respectively.

Conclusions

Post-platinum patients with EGFRex20ins aNSCLC remained on mobocertinib for 5 months in the EAP. Over half of patients had ≥2 orders of mobocertinib and a prolonged estimated TTD of 11 months, suggesting clinical benefit (i.e., response or stable disease). Mobocertinib appears effective in a real-world setting.
