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.
