RE:RE:RE:RE:TH1902 effects on Progranulin Sure delivering the chemo bomb might be all that is needed to finish off the cancer (let's hope so). But it may not. So identifying other MOAs might be extremely important. I'm jumping way ahead here but being able to say your drug also shuts down plasticity mechanisms in the cancer cell (I'm suggesting VM is just one mechanism of many), the sort of basic mechanisms the cell uses to spread and evade treatments is something that I think could contribute to the efficacy of the drug and certainly get partners salivating. I'm not saying the company has proved all this but it is potentially there and could turn out to be hugely valuable.
I like a targeted chemo bomb, I like a targeted chemo bomb with added extras even more.

TH1902 doesn't have to competitively inhibit progranulin from binding to Sortilin. It kills the cells that have Sortilin leaving nothing for progranulin to bind to.

It may also be part of the disruption of vascular mimicry that they have seen in vitro. That is one of the more intriguing possibilities of the peptide and whole platform. If they can uncover that it does work beneficially in three different ways, it's not just a home run, it's a grand slam....or for our hockey-heads, a hat-trick!

"Progranulin is involved in biological processes such as wound healing, inflammation and cancer progression. Progranulin and its receptor sortilin are known to be highly expressed in subgroups of breast cancer and are further associated with a clinically aggressive phenotype."
