Good afternoon ndr50
Pfizers 11a trials conclusion below.
Results: In total, 212 patients in 35 sites were treated; mean (SD) baseline PASI score was 20.8 (7.68). Decreases in PASI at week 12 were statistically significant compared with placebo in five treatment groups. The greatest change from baseline (least squares mean change -17.3 [95% confidence interval, -20.0 to -14.6]) was observed in the 30-mg QD continuous treatment group. Overall, 136 patients experienced treatment-emergent adverse events, including six serious adverse events in five patients and 13 discontinuations in treatment groups because of adverse events. No herpes zoster cases or major adverse cardiac events including thromboembolic events occurred.
Conclusions: PF-06700841 was generally effective and well tolerated in patients with moderate-to-severe plaque psoriasis.
QD for those that do not know, defines one a day ( from Latin quaque die)
Our proposed range for dosage was 12.5 mg total body, up to 10mg per kilo of body, weight maximum 1000mg per individual. No adverse effects were found in preclinical studies, and to establish an MTD at 30 times treatment levels did not produce an MTD, TM stated that we may need to go as high as 100 times treatment these levels. Very impressive and I for one look forward in earnest for out toxicity results.
Janus kinases are methods in controlling signalling and each have their dedicated Jak STAT pathway but at the same time rely on cross signalling down stream signalling and act as precursors to signalling. . Extremely complex. It is the molecules that make up control of each target and their respective proportion in my view are of extreme importance. With our patented crystallisation of a compound potentially ensuring up to 100% purity of a compound and administered vis capsule as an oral route ensuring the best possible LADMET i am also of the opinion we will be significantly better than Pfizer Tyk2 Jak1. If I were pessimistic I would say at least as good as.
Interestingly I find no mention of Pfizer Tyk2 Jak1 as a proposed treatment for Covid.
Covid is not going away soon. Eventually it will become endemic. An effective treatment will be required not just for Covid as it is at present, but also as a treatment in contingency plans should we experience any forthcoming serious SARS outbreaks.
