With in vivo Car-T becoming increasingly hot, it was probably only a matter of time before Gilead got in on the action, and the group on Thursday swooped for one of the most advanced players, Interius BioTherapeutics.
The $350m up-front fee is about in line with the $425m that AstraZeneca shelled out for EsoBiotec earlier this year, but much lower than the $2.1bn that AbbVie paid for Capstan in June; the latter deal is largely focused on autoimmune disease.
In vivo Car-T is designed to spur a patient's body to manufacture their own Car-T therapy, thereby reducing the cost, time and inconvenience associated with current autologous products.
Privately held Interius is one of a handful of in vivo Car-T players already in the clinic, with its lead project, the CD20-targeted INT2104, starting the Australian first-in-human Invise trial in B-cell malignancies last October. Initial results are expected in the second half, so perhaps Gilead had a sneak peek and liked what it saw.
Another relatively advanced player is Umoja, which has two assets in the clinic for B-cell cancers: UB-VV111, which targets CD19, and is in the US/Australian phase 1 Invicta trial; and UB-VV400, which hits CD22, and is in a Chinese phase 1.
AbbVie also has a collaboration with Umoja, which includes an option to license the smaller group’s CD19 projects, including UB-VV11. It’s not clear what the recent Capstan deal means for Umoja, as Capstan’s lead project, CPTX2309, also hits CD19.
Despite Interius and Umoja being first to the clinic, the EsoBiotec-originated ESO-T01 beat them to the punch in reporting data. Case reports published in July detailed four responses among four Chinese multiple myeloma patients receiving a low dose, bolstering hopes for the project and in vivo technology in general.
Several big groups are already involved in in vivo Car-T, with some showing more intent than others. If the excitement continues, more deals could follow.
