A phase II study of the Ras-MAPK signaling pathway inhibitor TLN-4601 in patients with glioblastoma at first progression.

This phase II trial was undertaken to evaluate the efficacy of TLN-4601 in patients with glioblastoma (GBM) at first progression. TLN-4601 inhibits the Ras-MAPK signaling pathway, and in animal models crosses the blood-brain barrier and accumulates in implanted gliomas, possibly by binding specifically to the peripheral benzodiazepine receptor. A maximum of 40 patients with recurrent GBM were to be enrolled in this study.

Treatment of typical (enteropathic) hemolytic uremic syndrome.

Typical enteropathic HUS (eHUS) is triggered by Shiga toxin (Stx)-producing bacteria (STPB), predominantly Stx-producing ESCHERICHIA COLI O157. The cell biological aspects of Stx have been well defined, but host factors potentially predisposing to the development or severity of HUS remain elusive. Treatment of eHUS includes supportive measures and invasive extracorporeal therapies.
