Objectives:

Durvalumab is funded in unresectable locally advanced non-small cell lung cancer (NSCLC) with PD-L1 expression ≥1%, without progression after platinum-based chemoradiotherapy and treatment duration of 12 months. Patients must present adequate performance status (PS). Until now, only compassionate use has been authorized, without some funding requirements. The aim is to describe conditions of compassionate use of durvalumab in locally advanced and unresectable NSCLC, comparing with the financing conditions, as well as to provide the real-life results of effectiveness and security.

Methods:

A retrospective descriptive study from 01/12/2017 to 29/02/2020 was conducted. The effectiveness was assessed with overall survival (OS) and progression-free survival (PFS) by Kaplan Meier method using SPSS Statistics®. Safety was evaluated through adverse reactions (ARs), grade, interruptions and suspensions.

Results:

There were 5 male patients recruited. PD-L1 was ≥1% in one patient. The 80% of patients presented PS0. The median follow-up was 19 (7-25) months. One of the patients (20%) met the funding criteria. There were no deaths, so the mean OS could not be calculated. The mean PFS was 20.8 (13.6-28.1) months. There were 17 RAs episodes. The most frequent RAs were: 4 (23.5%) respiratory infections, 3 (17.6%) cough and 2 (11.7%) erythematous lesions. There were 16 (94.1%) RAs grade 1, and 8 treatment interruptions were recorded, without suspensions.

Conclusions:

There are important discrepancies between the compassionate use of durvalumab in unresectable locally advanced NSCLC and the financing conditions. Durvalumab has showed an important effectiveness and aceptable tolerance, although these results should be evaluated with caution.
