Which platform and how long might it take?15 Aug 2022 17:37
Which platform for this drug, and how long to recruit the 1000+ patients required ?
We're all hopeful of STRIVE of course - it fits us very well in lots of ways and we know it's probably the fastest bet by a long chalk - with the continuing (relatively) high levels of Covid in the States.
The evidence linking us is all circumstantial but RM stated in the RNS that ended Activ2 that "lead investigators from ACTIV-2 and Synairgen are in ongoing discussions to try to identify an appropriate clinical trial to continue the evaluation of SNG001." (17/3/22) STRIVE is the first such platform that might be considered "appropriate", and the first new iniative from NIH since Activ2 was suspended. We'll know within the next 2 weeks if P3 and A2 data can combine to get us onto this new platform and if the dots start to join up.
If SNG gets onto it now, there's a chance we'll see results and maybe even an EUA within a year. There's also a chance it'll take a lot longer unless new variants reverse the global reductions in hospital admissions.
If the company is applying to Recovery the timescale will surely be much much longer. Free trial or not. Between late March (when it commenced) and July 25th 2022, Pfizer dosed 200 patients with Paxlovid. 200 out of the "several thousand" required for its inpatient Recovery trial. With the drug available at 177 UK hospitals. 50 patients a month from a company with limitless resources as the second Omicron wave increased numbers in hospitals. Doing the maths on this ( and setting a conservative 2000 as the number required ) Paxo should announce LPD in mid 2025.
Looking at the most recent Our World in Data slides and apart from the US you'll see mostly empty ICUs and negligible numbers of new ICU admissions everywhere. If the most poorly are not progressing to ICU then it's difficult to see where anyone's inpatient trialists come from - even in the US.
RM said ""Conducting clinical trials in the time of COVID-19 is challenging " in the same RNS. I'm sure he'd agree 6 months later that conducting a Covid 19 trial at a time of very little Covid will be even more challenging.
Everything can change really quickly of course - but without something that creates an added level of urgency - ie a new variant that evades both mabs and tabs - or a performance so stellar that the trial is halted early - SNG will most likely spend at least the next year on STRIVE - or the next however many years on another less well support platform.
My purpose here is to introduce a realistic and fact-based note of caution about the speed of the next step. And I'd like to ask what other options there are for a PT ? And can anyone point to Patients-per-month timescales for the most recent trialists on those platforms ?
