Theralase Technologies Inc. > Higher efficacy numbers soon?

Post by ScienceFirst on Feb 09, 2023 12:31pm

Higher efficacy numbers soon?

Some whine on TLT management, depict them as poor managers.  That's probably coming from those that lack vision, when TLT is working for their own investments!   We had similar reaction from Bungee and some others when we had no news for 6 months between Ph. 1b p#4 and p#5, while TLT was working on an optimized procedure!

In the Jan. 3rd Biotuesday, there was this interesting info below that went unnoticed to many and that might potentially explain why the submission of the FDA Breakthrough Therapy in Q1. (so potentially up to March 31).


If you look closely, there is a pool of 5 more optimized patients within 3 months (p#30-34), between 360 and 450 days.  And we also know that p#26 was in the Nov. 30 data and reached its 450-days around mid-November.  So lets assume for a moment that TLT could add 5 more by mid-March.  That would mean they could exclude the first 50% (6) of the 12 undertreated patients and submit data on p#7 to p#31, for a total of 25 patients, 20 of them being optimized patients.  That would di-facto increase their efficacy %s both @90-days and 450-days.  Such improved efficacy %s would then appear in the FDA press release, which is what matters the most.  We could then be above 60% @90-days (instead of at 53%) closer to 35%+ @450-days (instead of at 28%).  Attendance at ASCO-GU and AUA would then see an additional progress since what they saw on the posters.

In November 2022, Theralase reported encouraging interim clinical data from the pivotal clinical study, with 53% (43 evaluable patients) achieving a complete response at 90 days; 29% (34 evaluable patients) at 360 days; and 28% (29 evaluable patients) at 450 days.

It would be nice if they would let us pick and chose which 25 patient's data to submit but I think we are stuck with the "dirty dozen" . 
Comment by ScienceFirst on Feb 09, 2023 1:06pm
They cannot cherry-pick but they could probably start their pool of patients with an offset as the FDA never said "the first 20-25 patients".  No matter what, we already have acceptable Numbers.
Comment by CAinPlap on Feb 09, 2023 2:49pm
Yes I believe even with the dirty dozen included, our results are still ahead of Keytruda.
Comment by Eoganacht on Feb 09, 2023 3:25pm
Right 9% higher CR than Keytruda and 4.5% CR higher than the recently approved Adstiladrin. And that with one hand tied behind our backs!
Comment by CancerSlayer on Feb 10, 2023 1:30am
  I'm honestly surprised the FDA would even consider the first 12 for any type of designation/approval (BTD, AA, etc.).  In my view, the originally flawed protocol somehow bypassed the watchful eyes of multiple experts/groups, including the IRB/FDA...& it's uncertain to me who or which PI specifically caught the error.  Nevertheless, the modified & correct protocol ...more  
Comment by ScienceFirst on Feb 10, 2023 5:30am
If, for whatever reasons, they have to live with the 12 undertreated, they can decide to submit data on 31 patients around March.  That would be another alternative to lower the impact of the first 12 patients.  Instead of them having a weight of 50% (12 out of 25), they would have a weight of 39% (12 out of 31).  It would du facto improve our last reading. One thing is not allowed ...more

I think you are right CS and there is precedent, Phase I. They were caught off guard by the recurrence in P4  because of UTUC and they adjusted so when P5 and P6 came in cancer free they stopped Phase I and moved on to Phase II because the results merited that. So even though they have to include the under treated 12 if they have their '20 to 25' since the first 12 then they can ...more

Does anybody else believe (as I do) that we will see an NR early next week with updated data, so the latest complete set of data can be presented by Dr Kulkarni at GU-ASCO cancer symposium on Feb17?
Comment by CAinPlap on Feb 10, 2023 10:23am
My thoughts are early the following week after RDW has been reinstated.
Comment by 99942Apophis on Feb 10, 2023 11:14am
Yes Yajne that thought has a strong probability of occurring and I'm sure many here are thinking that will happen. 
Comment by 99942Apophis on Feb 10, 2023 11:03am
True enough CancerSlayer and regardless which sector is in discussion medical, industrial,  agricultural, all follow practical corrective direction as the best path forward with little to no attention to the previous mistakes. 
Comment by Legit62 on Feb 11, 2023 6:37am
CancerSlayer well said and i completely agree with your reasoning. If anyone with any type of science background reviews our data, this will pop out like a sore thumb
Comment by CancerSlayer on Feb 11, 2023 12:45pm
  Yes legit62...PDT's somewhat checkered history has made it difficult for the newer water-soluble photosensitizers (PS) to make headway in the medical community.  I believe an approval of our ACT will finally reawaken interest in the use of PDT & certainly ignite more research.  The PDT paradigm is shifting & our ACT could soon be the go-to option, replacing the ...more
