Nivolumab plus chemotherapy and nivolumab plus ipilimumab have been approved as first-line therapies for patients with advanced OSCC based on the results of the phase 3 CheckMate 648 trial (n=970) [1]. At ASCO-GI, Prof. Ian Chau (Royal Marsden Hospital, UK) presented the results of a quality-adjusted time without symptoms and toxicity (Q-TWiST) analysis to compare the quality and quantity of survival of participants who received either one of the two nivolumab-containing regimens with patients who received chemotherapy alone [2].
Participants in the nivolumab plus chemotherapy arm spent the most time in survival without symptoms or toxicity (8.0 months). In the nivolumab plus ipilimumab arm and chemotherapy alone arm the corresponding durations were 6.6 months and 5.8 months, respectively. Participants in the nivolumab-containing arms also spent more survival time in toxicity or with symptoms.
Prof. Chau shared that the difference in Q-TWiST duration between the nivolumab plus chemotherapy arm and chemotherapy alone arm was 1.7 months, exceeding the threshold for clinical importance of 1.1 months. Similarly, the Q-TWiST difference between nivolumab plus ipilimumab and chemotherapy alone was 1.3 months, in favour of the first regimen.
“The Q-TWiST analysis favoured nivolumab plus chemotherapy and nivolumab plus ipilimumab over chemotherapy alone, further supporting these regimens as first-line treatment options for patients with advanced OSCC,” concluded Prof. Chau.
