Theratechnologies Inc T.TH

Alternate Symbol(s):  THTX

Theratechnologies Inc. is a Canada-based clinical-stage biopharmaceutical company. The Company is focused on the development and commercialization of therapies addressing unmet medical needs. It markets prescription products for people with human immunodeficiency viruses (HIV) in the United States. The Company's research pipeline focuses on specialized therapies addressing unmet medical needs in HIV, nonalcoholic steatohepatitis (NASH) and oncology. Its medicines include Trogarzo and EGRIFTA SV (tesamorelin for injection). Trogarzo (ibalizumab-uiyk) injection is a long-acting monoclonal antibody which binds to domain 2 of the CD4 T cell receptors. It blocks viral entry into host cells while preserving normal immunologic function. The Company is also investigating an intramuscular method of administration of Trogarzo. EGRIFTA SV (tesamorelin for injection) is approved in the United States for the reduction of excess abdominal fat in people with HIV who have lipodystrophy.

Surely it's better to take your investment money to companies that work on this tech rather than endlessly hoping THTX will begin working in a tech space it's shown zero interest in.

How can you make such a claim when you are not part of the scientific team having access to the Phase 1 data,,,,,You keep drawing conclusions not based on facts....No wonder you never made to the top ......That is probably why you appear to be a frustrated low ball science guy

About returning to the drawing board, I think they were on the drawing board all along with SN38, si RNA, and they sure thought about other options. I still hope they will wake up to radioisotopes and it's potential for both proper screening of patients and therapy.

Many were interested to find other examples of PDCs in clinical development. I found another one this week-end searching for the most recent developments in PRRT (peptide receptor radionuclide therapy). This PDC is Pb212-DOTAMATE  a ligand od the somatostatin receptor. Pb212 stands for Lead 212, an isotope of lead that is emiting alpha radiation, shorter and more powerful radiations than beta radiation you have with Lu177. These alpha radiations are strong enough to break the double strand of DNA in cells, where beta radiations allows to break only one strand and allow for subsequent DNA repair by cells.

I point that just to show that PRRT is a growing field in cancer treatment, and PRRT starts with peptide and receptor. It's a PDC based therapy with no need for cleavable linker and able to overcome all known resistance to chemotherapies. Thera has a peptide and receptor couple (TH19P01 and sortilin), so they have the perfect candidate to go in this field as soon as they have a proof of concept. Mr Beliveau and Marsolais, wake up!

But we do know that TH did decide to share some additional info with us and it seems like the news that patient #2 went through multiple dosage levels and cycles was a message they intended to convey to investors. I don't  think they were trying to offer us any proof, just trying to keep us hopeful until the final results are out. Since most investors are not scientists looking for definitive proof before they get more optimistic, I think TH revealing this now was a good strategy. With the sizable delays in the phase 1a, investors needed something to hold onto to remain hopeful about the outcome. 

Now, they are likely in the midst of dosing the last three patients at 300mg right now. So, we will hear the final results of the  phase 1a before too much longer if Christian was right with his expectations based on prior bloodwork that the 300mg dose will not encounter the same toxicities that those at the 420mg dose saw. Since the number of patients are so small, there will be nothing statistically significant in that data but we could walk away from reviewing knowing that the phase 1b and phase 2 trials stand a very good chance of giving the scientists the statistical significance they are looking for. What is key for investors at this point is for the phase 1a to give TH a legitimate future in cancer and not be a failure that requires TH to return to the drawing board. Based on statements the company has made, patient #2 and actions the company is taking, it is not too hard to convince oneself that TH-1902 still has an interesting future and its prospects have not been cut off at the knees with the first human testing. That needs to be officially confirmed and I expect there will be some phase 1a data revealed that will keep us worrying to some degree about the next round of testing, but that is normal. 

I imagine that statistical significance will be hard/nearly impossible to achieve in phase 1b as well with only 10 patients per cancer type for most of the cancer types tested. Could statistical significance be calculated if there are 30 responders across 75 patients in multiple cancer types or would each cancer type have to be viewed individually?

We need to look at it objectively. His first dose was 60 mg/m2. A quarter of the MTD of docetaxel alone. I know they saw some efficacy in animal models at a quarter of the dose, but a real patient is not an animal model.

Marsolais in the KOL back in June said that they were close to the MTD of docetaxel alone at that point, so they were at 200 mg/m2, the third cycle of patient #2. So by the end of August it is sure that patient #2 had the four disclosed doses. After that, what happened to patient #2. That's seven months ago. If he continued at 300 mg/m2, why they did not disclose it? If he did a single cycle at 300 mg/m2 than dropped off the trial, it means he was on the drug for about four months. I don't see what conclusion we can draw from that.

I don't say nothing good happened to this patient. I just say that with what Thera disclosed, we cannot reach any conclusion. If the goal of disclosing that was to let us know TH1902 is effective, sorry, to me it's not the case. What happened to patients #2, #4 and #5 after the first 300 mg/m2 dose? Mystery. We don't know. Same for patients #8, #9, #10 and #11. They were treated at 420 mg/m2 for at least two doses. Are they still on the drug at a lower dose??? Again, we don't know.
