Alpine Immune Sciences Reports FDA Partial Clinical Hold on NEON-2 Trial of Davoceticept (ALPN-202) in Combination with Pembrolizumab
-NEON-1 Study of ALPN-202 as a Monotherapy is Unaffected-
The partial clinical hold was prompted by Alpine’s report of a Grade 5 serious adverse event (patient death) in the NEON-2 trial. The participant had choroidal melanoma previously treated with nivolumab and ipilimumab, and had received a single dose each of davoceticept and pembrolizumab. The participant’s death was attributed to cardiogenic shock, considered by the treating physicians as likely related to immune-mediated myocarditis, or possibly infection.
“Patient safety remains, as always, our top priority,” said
Patients currently enrolled in the NEON-2 trial may continue to receive davoceticept and pembrolizumab, although no additional patients may be enrolled until the partial clinical hold is resolved. The partial clinical hold does not affect the ongoing NEON-1 clinical trial of davoceticept as monotherapy (NCT04186637).
About Davoceticept (ALPN-202)
Davoceticept (ALPN-202) is a first-in-class, conditional CD28 costimulator and dual checkpoint inhibitor intended for the treatment of cancer. Preclinical studies of davoceticept have successfully demonstrated superior efficacy in tumor models compared to checkpoint inhibition alone. Completion of dose escalation and initiation of expansion cohorts of NEON-1 (NCT04186637), a Phase 1 monotherapy dose escalation and expansion trial in patients with advanced malignancies, is anticipated in the first half of 2022. NEON-2 (NCT04920383), a combination study of davoceticept (ALPN-202) and pembrolizumab was initiated in
