At present translational studies are continuing
with 1802.
With regards to development we sit in a great position to carry out these studies.
Allosteric Tyk2 has not shown the efficacy that was hyped up to be.
Clearly it is evident that Tyk 2 on its own an be tailored to have greater efficacy in Indications with the addition of Jaks 1,2 &3
Those of us that have been here a while will know that 100% selectivity of a single Jak cannot be obtained. However, a Jak selectivity can be obtained to give the desired effects in a particular indication or Indications
No such thing here as one size file fits aĺl as demonstrated by deucravacitinib in UC.
The thinking behind the Allosteric Tyk2 is clearly along the same lines as the early Jak1 Jak2 and Jak3 formulated compounds that were given black box warnings by the US regulatory authority.
We are far from alone in believing that we can create a compound with greater efficacy in the indication of Psoriasis than Deucravacitinib.
737 is a complex issue as there are an increasing number of suitable candidates that it can be partnered with thT overcome many of the problems associated with cancer developing resistance to CHK1 inhibition.
What cannot be ruled out is an agreement at so.e time resulting in Combination therapy leading to clinical trial. It could be announced any time but no indication as to when
