The randomised, multicentre, open-label trial will evaluate the treatment effect of once-a-day buparlisib along with weekly paclitaxel compared to weekly paclitaxel alone in HNSCC patients that have progressed after previous anti–PD–1/anti–PD–L1 monotherapy.

Adlai Nortye president and chief medical officer Lars Birgerson said: “There is a high unmet medical need for patients with recurrent or metastatic HNSCC after anti-PD-1/anti-PD-L1 therapy.

“As the trial is now fully enrolled, we eagerly look forward to the results, which may change the paradigm of second-line treatment for HNSCC and provide a new treatment option for patients worldwide.”

Buparlisib, an oral pan-PI3K inhibitor designed to target all class I PI3K isoforms, is active in both solid tumours and haematologic malignancies.
