Genmab has stopped enrolling patients for an early-stage trial of a cancer candidate it obtained in its $1.8 billion acquisition of US-China biotech ProfoundBio.
The Phase 1/2 study of GEN1286 was meant to enroll 260 patients with advanced solid tumors, but it has stopped at just 23, according to an
update
on ClinicalTrials.gov this month. The update also notes that the trial is “active, not recruiting.” Genmab confirmed to
Endpoints News
that the information is accurate, but declined to provide further comment.
GEN1286, a bispecific ADC that targets EGFR and c-Met, is not the first drug originally developed by ProfoundBio that Genmab has lost interest in.
In November, Genmab dropped a CD70-targeting ADC called GEN1160 after
slow enrollment
in a Phase 1/2 lymphoma study. A few months before that, it
ended work
on a PTK7-targeting ADC known as GEN1107, which showed a poor risk-benefit profile in a Phase 1/2 solid tumor trial.
All three drugs joined Genmab’s pipeline after it bought ProfoundBio in an all-cash transaction
completed
in May 2024. Genmab is still advancing the key asset at the heart of the deal — an FRα-targeting ADC for ovarian and endometrial cancers called rinatabart sesutecan. The drug is currently in a Phase 3 trial in endometrial cancer, with topline data expected in 2028.
Genmab has been trimming its oncology pipeline more broadly following the September announcement of its
$8 billion acquisition
of Merus, which is focused on head and neck cancer. In December, Genmab
axed
a PD-L1x4-1BB bispecific antibody called acasunlimab, which had previously been partnered with BioNTech.
