the dual tky2 jak1 inhibitor will not be ours. take that 100%.
however as a similar composition to 1801/1802 ot has importantly proved a good tolerability in safety profile and efficacy.
allisteric tyk2 failed in uc
jak1 and 3, fine in some indications but can lead to safety concerns and even black box warnings.
will not go into detail here. as much as l have looked at it. jakis as we know them ie 1,2&3 have high efficacy. however,many suffer from the dreaded black box warnings.
tyk2 especially allosteric is an immunotherapy more akin to a regulator of the immune system.
it is reported to regulate jak3 but it is not able to interact with jak3.
jak2 is heavily associated with safety concerns.
what we can look at here is the effectiveness of the jak1 2 and 3 with associated safety concerns but extremely moderated by the addition of tyk2.
hence if we have good workability between the jakis and tyk2 when combined ( as tim stated optimum amount) the resulting compound ought to give better results in many indications then any other jaki or tyk2 inhibitor.
add the crystallisation of a structure to ensure purity at up to 100% and the advantages (albeit small) of capsule formulation to maximise up rake via the oral route an d then you will have not only one of the best immunotherapy inhibitors available but the best oral dual inhibition ie tyk2 jak1 in many indications.
it is here at the later clinical stages of trial development where the benefits of attention to detail will pay off.
as was stated by tim and co and bought up again several times since. it is now that the companies require data. ' right, give us some data '
np ***** footing around here, no data no deal.
hence it is the data from our dose escalation that will be of the upmost concern.
in certain indications we will be superior to allosteric tyk2 eg deucra. this was stated by tm.
as an indication the chemical composition of sar 737 was taken from tim and co.
should we take the advantages of a generally safer compound than other chk1 inhibitors and greater efficacy in certain types of cancer ( mainly due to us being chk1 and not chk1 and chk2) plus administered via the oral route it can be realised that we are at the moment and for the time being at the forefront of design and manufacture of small molecule kinase inhibitors.
very heavy workload at moment not have time to post much here. best l can do to calm any concerns or doubts with regards to sareum tweet.
the reason for the tweet
deucravacitinib. ie becoming co.mo nly acceptable as very good safety profile. we have tk2
tyk2 jak1 greater efficacy than tyk 2 alone.
in both these conditions it is evident that sareum believe they can be better.
regards and if any mistakes apologies as not had time to read before posting.
