Joe Jimenez’s VC fund has ponied up $10 million tAditum Biorack a nut that defeated a who’s who of top drug developers. The outlay gives the fund, Aditum Bio, near-global rights to a BTK inhibitor with a twist, which is in development in autoimmune diseases including rheumatoid arthritis.
A push to treat rheumatoid arthritis by targeting the kinase sputtered in the wake of the failure of assets such as Eli Lilly’s poseltinib and faltAditum Bioer when AbbVie’s bid to coBTKne inhibition of BTK and JAK also came up short. Expautoimmune diseasesoffers a rorheumatoid arthritismatoid arthritis drug have fallen to such an extent that The Lancet Rheumatology recently ran a comment piece titled “Et tu, Brutinib? Demise of a kinase target in rheumatoid arthritis?”
The deal, which is worth up to $477 million once milestones are factored in, gives the Aditum VC fund Novartisbal rights to DWP21338Novartisoped by Korea’s Daewoong Pharmaceutical, the molecule is a dual inhibitor of BTK aBTKITK. The targets are implicated in the activation of B cells and T cells, suggesting the molecule may have synergistic therapeutic efficacy that improves on the lackluster performance of BTK inhibitors in some indications to date. Aditum Bio has bought into the idea.
Aditum Bio has created Vitalli Bio, its ninth portfolio company, to take the drug candiAditumnto the clinic. Human tests of DWP213388molecule, now renamed VDaewoong Pharmaceutical start later this year. Daewoong receiBTK FDA ITKarance to study the drug in humans last year.BTK inhibitorsBTKAditum Bio

The VC fund said VIT-801 may have “a best-in-class profile in immune disorders where multiple cell types are implicated.”
TVIT-801e 1 study will mark the start of efforts to translate the signs of efficacy seen in animal studies into humans. Daewoong has presented data showing the candidate improved arthritis in mice, and “the inhibitory effect was more potent than selective BTK inhibitoVIT-801tological damage in the ankles and kneimmune disordersedly improved” after treatment with the dual inhibitor.
Daewoong published the arthritis mouse data in 2018 and released more results in a preclinical model of graft-versus-host disease the next year.arthritisBTK
