After hashing out comeback plans, Deciphera looks to raise $125M from stock sale
Earlier in January, Deciphera outlined plans for a new Phase III study of its tyrosine kinase inhibitor Qinlock, still hoping to move it into an earlier line of treatment for digestive tract cancer after it failed a pivotal trial in 2021.
But in order to run a new clinical trial, Deciphera needs cash. So the Waltham, MA biotech is selling its shares via a public offering, it announced Wednesday afternoon.
Deciphera plans to sell $125 million of its shares, and it’s giving underwriters an option to buy an additional $18.75 million.
Deciphera’s stock $DCPH, which closed at $20.61 Wednesday, fell around 10% in pre-market trading in response.
Qinlock was approved in 2020 for fourth-line gastrointestinal stromal tumors, or GISTs, and Deciphera had hoped to turn it into a second-line treatment option. But Qinlock failed a Phase III trial versus standard-of-care sunitinib, and soon after, Deciphera scrapped parts of its pipeline and cut 140 staffers.
But in January, Deciphera said it found a new way to expand Qinlock’s label. Deciphera did a subgroup analysis of 52 patients with mutations in KIT exon 11 and 17/18, a gene that encodes for the kinase Qinlock blocks. In that subgroup, patients who got Qinlock had a median PFS of 14.2 months, compared to 1.5 months for those on sunitinib. The new Phase III trial will test Qinlock as a second-line treatment for patients with those KIT mutations only.
Outside of the new clinical trial, Deciphera also said that the money will be used to fund work on its other kinase inhibitors, including vimseltinib, which is in a Phase III trial for tenosynovial giant cell tumor, a type of joint tumor, and DCC-3116, which is in early-stage studies.
