Trial of CT38 for ME/CFS by Cortene Inc.: big claims being made...

Even if it only works for some people with ME-CFS (given that there might be so many different causes for the symptoms, this may be expected) we should all be allowed to try it. It certainly can't be any worse than being made to do GET, which makes more people more ill than better!

Hi @Hank G, welcome to the forum.

I'm afraid I can't agree with your comment. Until there is a double blind trial, we can't know whether it works for anyone. Nor do we know whether the side effects will be worse for people with ME than GET as you suggest. That is simply not known until after the trial. I think it's irresponsible to encourage people to try drugs simply on the grounds that they are currently being tested.

I assume you are familiar with the Rituximab story which looked so promising in early trials, but turned out not to be a beneficial treatment for ME after all. And some people were give Rituximab privately before the trial results came out - a waste of their money and at risk to their health from possible side effects from what turned out to be an ineffective treatment.

Hello @Trish. But, was´nt the Rituximab Trial based on an untested hypothesis? I am not suggesting that the Cortene Trial would be any better but it is certainly built on a hypothesis very similar the "Metabolic Trap" hypothesis, which I personally find to be quite convincing (that is my subjective view of this). What do you think?

Hi @Dudden. No I don't see that it makes any difference whether there is a hypothesis or not. As I understand it, the hypothesis the Cortene test is based on is unproven. We can only know if a drug is effective if it has been properly tested.

Indeed. I think what I meant to say was, if Davis and Phair have similar ideas to Cortene, it would mean much. But as you say, it is quite early to tell if the trial is successful. Let us hope that it will result in a positive outcome.

The ME/CFS patients, interestingly, reacted to the drug at far lower doses than the healthy controls did in a past study. That unusual sensitivity potentially validates Cortene’s disease hypothesis and could indicate that CT38 may be getting at a core part of ME/CFS.

Or it just represents questionnaire answering bias because the study was not blinded....
 
Just because CRF2 activation is necessary & sufficient to produce learned helplessness, that doesn't mean that LH is the only thing that it can cause. Just did a bit of googling and there seemed to be plenty of other things mentioned in relation to CRH (corticotropin releasing hormone).

From the registration of the trial:

"The primary endpoint will be the change in the average total daily symptom score (TDSS), over 28-day periods immediately prior to the first treatment (pre-treatment) and immediately prior to exit from the trial (post-treatment). The TDSS is the sum of 13 individual symptom scores, each recorded daily by the patient on a 6-point scale (0=none, 1=very mild, 2=mild, 3=moderate, 4=severe, 5=very severe). [...]

The secondary outcomes will assess function (assessed by patient record and, Fitbit monitoring), effects on vitals, orthostatic intolerance (assessed by standing tests at enrollment and exit) and general health status, as well as safety assessments."

Well. At least they've had the honesty to pre-register the outcome most likely to be subject to bias as the primary outcome, instead of switching it later, I guess?

How fitbit data matches with symptom scores will be interesting. For the record I was using symptom scores to titrate treatments, in a clinic, in 1993. These were used regularly, but objective measures were determined from time to time.
 
The answer to these questions from this small (14 patients) non-placebo-controlled trial was a qualified yes. The drug appears to be safe. The ME/CFS patients, interestingly, reacted to the drug at far lower doses than the healthy controls did in a past study

I'll want to see the paper to see the definition of 'reacted' here. Especially given the high placebo response in the Rituximab trial.
