TIGIT class of checkpoint inhibitors fails with Keytruda

[Noteable]

March 17, 2023 - Merck's (MSD) co-formulation of Keytruda and anti-TIGIT therapy vibostolimab did not improve progression-free survival compared to chemotherapy alone in patients with metastatic non-small cell lung cancer that had previously been treated with immunotherapy and platinum-doublet chemotherapy.

This failure suggests that the hypoxic TME was unable to be remodeled nor could the innate system be "primed" for Merck's anti-PD-1 Keytruda to work. 

These results add further credibility to the affect of ONCY's pelareorep on remodeling the TME and pelareorep's ability to "prime" both the innate and adaptive immune systems prior to the addition of a PD-(L)1 checkpoint inhibitor like Keytruda or Tecentriq or Bavencio, for example.

In March last year Roche’s trial with their anti-TIGIT drug tiragolumab in small cell lung cancer (SCLC) also ended in failure.   Adding tiragolumab to checkpoint inhibitor Tecentriq and chemotherapy failed to improve progression-free survival in the study of 490 people undergoing first-line treatment for SCLC, causing the trial to miss one of its co-primary endpoints. https://www

Roche & Merck may be pursuing the acquisition of Oncy just a tad bit more forcibly at the moment. We'll see what Roche's new CEO has first on the M&A docket soon.

April 27, 2023 - Roche is "tightlipped" on another TIGIT possible failure .....  as they dodged questions about whether their candidate has flunked yet another phase 3 trial. Roche needs to add ONCY's pelareorep to stimulate the immune system and convert an immunosuppressive tumor microenvironment (TME) to facilitate the TIGIT and PD-1 immune checkpoint inhibitor tecentriq

September 14, 2023 - Bristol Myers Squibb disclosed Thursday at its R&D Day that it cut its anti-TIGIT program and is advancing its TIGIT Bispecific in NSCLC & gastric Solid Tumors program (Differentiated TIGIT bispecific antibody targeting both TIGIT and CD96) further steering Roche towards ONCYs pelareorep as an TME immunomodulator for Roches anti-TIGIT

October 30, 2023 - Roche is strapped into the first car for the long haul. It’s paid off, says Charlie Fuchs, senior vice president and global head of oncology and hematology drug development at Genentech and Roche. “I believe in TIGIT,” Fuchs told Fierce Biotech on the sidelines of the European Society for Medical Oncology meeting, held Oct. 20 to 24 in Madrid.

Not only that, but the confidence interval

Noteable would you agree with the idiot below that Pela clearly didn't do well enough woth paclitaxel and big pharma must have walked away?

The Bracelet-1 resutls were signficantly successful and have demonstrated pelareorep's single agent anti-cancer activity. As pointed out beforehand, it was necessary to differentiate pelareorep's effectiveness from other agents that pelareorep may be combined with. With respect to the Bracelet-1 study, the patients enrolled in the three cohorts were heavily pre-treated and had failed

Thanks Azzak for asking Noteable that question. I will chime in with my non technical views that it is obvious pela improved pfs over the standard of care Paclitaxol by 50%. Pfs is correlated with OS but with pela OS may well be stronger and and relatively better as the immune response comes forward after about 4 months, as seen in the waterfall graphs for former trials. Then there is the panc

I like your positivity, but it appears that the big investors aren't buying what the company is selling.  Way too much selling for something that's supposed to look promising. The results don't seem to be impressing people.  Need something from the company to prop this up. $1 land is way to close now. Like $3 territory much better. Much easier to sleep. 

[westcoast1000]

You have no way of knowing what big investors think, nor what they want to buy from the company.  You have no way of knowing whether the results are impressing people, except to look at the results, which are impressive. The share price will stay low until progress is announced.

From these developments one can see that Big Pharma is having significant difficulty in finding novel cancer therapies, at the same time that Big Pharma is faced with a looming patent cliff. We also see that Roche has bet heavily on the TIGIT class of checkpoint inhibitors.
