AVA6000 and urothelial carcinoma4 Apr 2025 11:18
Continuing the theme of what's hiding in plain sight, whilst several indications were removed from the ClinicalTrials site with the 13 December update, urothelial carcinoma was added.

Urothelial carcinoma, "also known as transitional cell carcinoma, is the most common type of bladder cancer, and it can also occur in the ureters, urethra, and renal pelvis" (source: Google AI Overview) and so replaces bladder cancer on the ClinicalTrials site with a more specific bladder cancer indication.
Why do this? The urothelial carcinoma indication does not form part of any Arm in the current Phase 1b trial. One might deduce that the collaboration with Tempus AI has identified this indication as a viable target for AVA6000: "Multiple tumor types identified with ~80% of patients with high expression of FAP and SLFN11" (source: R&D Spotlight 8, slide 7).
So, as has previously been suggested on here, this indication could well be on the list because it being kept open as a further option for the development of AVA6000. This could be for Avacta to progress if and when funds allow, for instance following a licence agreement or partnership for TNBC (Avacta could take both STS and urothelial carcinoma forward in Phase 1b) knowing that a treatment for urothelial carcinoma would be of great interest to pharma companies or it could be that one or more pharma companies have an understanding with Avacta to progress this indication if early findings for the indications in the Phase 1b Arms are suitably positive.
So, which pharma companies would have an interest in this indication? Well, it is more a starting point than an exclusive list, but both Eli Lilly, through their POINT Biopharma acquisition, and Novartis have radioligand assets targetting FAP and Lilly have their canSEEK™ platform licensed from Avacta and Bachovchin. Both of these would, I believe, want to explore the AVA6000 option.
There are of course other companies with an interest in bladder cancer. Many other companies. Here are a couple of lists straight out of Google: 'AstraZeneca, Merck, Pfizer, CG Oncology and Astellas Pharma, among others' and 'CG Oncology, FKD Therapies, Bristol-Myers Squibb, LintonPharm Co., Ltd., ImmunityBio, Inc., Hamlet Pharma AB, Asieris Pharmaceuticals, Pfizer, Taizhou Hanzhong biomedical co.' Also... "There are approx. 80+ key companies which are developing the(sic) therapies for Bladder cancer." (source: Bladder cancer - Pipeline Insight, 2025 (Published 2024, 230pp, Global coverage): https://www.delveinsight.com/report-store/bladder-cancer-pipeline-insight
So, lots of potentially interested pharma companies and not all of them by any means 'Big pharma'.
