More about presentations at AACR10

Five presentations at the 101th annual meeting of the American Association of Cancer Research were highlighted a news release from Geron Corporation (dated March 3, 2010). One presentation that had an explicit focus on CSC was this poster:

Imetelstat, a telomerase inhibitor in phase I trials in solid tumor and hematological malignancies, has broad activity against multiple types of cancer stem cells [Presentation Abstract].

Also mentioned in the news release was an oral presentation by Jerry W Shay, given as part of the Major Symposium entitled: Role of Telomeres and Telomerase in Chromosomal Stability and Disease [Session Detail]. The presentation was:

Role of telomerase in normal and neoplastic stem cells [Presentation Abstract].

Another poster about the telomerase inhibitor imetelstat (GRN163L) was:

Sensitivity and resistance of non-small cell lung cancer to the telomerase inhibitor imetelstat [Presentation Abstract].

Comments: A search of the ClinicalTrials.gov database for GRN163L revealed 6 trials. Four were ongoing, but not recruiting participants. Two were still recruiting: 1) Safety and Dose Study of GRN163L Administered to Patients With Refractory or Relapsed Solid Tumor Malignancies; 2) A Study of GRN163L With Paclitaxel and Bevacizumab to Treat Patients With Locally Recurrent Or Metastatic Breast Cancer.

An analogous search for imetelstat yielded the same 6 trials. All 6 trials have been sponsored by Geron Corporation.

Sessions on CSC Therapeutics at AACR10

There were two poster sessions on Cancer Stem Cell Therapeutics at the 101st Annual Meeting of the American Association for Cancer Research (AACR). The sessions, Cancer Stem Cell Therapeutics 1 and Cancer Stem Cell Therapeutics 2, took place on the morning and afternoon of April 20, 2010 [FriendFeed entry].

Two posters presented in the 2nd session have been highlighted in a news release. See: Alchemia’s HyACT Technology Enhances the Killing of Cancer Stem Cell Populations in Breast and Colorectal Cancer, Business Wire, April 20, 2010 [FriendFeed entry]. One of these is Poster #4293: Evaluation of activated CD44 as a biological target in the eradication of breast cancer stem cells, by Vera J Evtimov and Tracey J Brown [Presentation Abstract]. The other is Poster #4278: HA-Irinotecan targeting of activated CD44 is an effective therapy for the eradication of putative colon cancer stem cells [Presentation Abstract].
