Curis Announces Phase II Clinical Plan for Hedgehog Antagonist Presented by Collaborator Genentech
Genentech indicates that it expects to initiate three Phase II clinical trials of GDC-0449 in 2008

CAMBRIDGE, Mass., Mar 14, 2008 (BUSINESS WIRE) -- Curis, Inc. (NASDAQ: CRIS), a drug development company focused on developing novel targeted medicines primarily for cancer treatment, today announced that its collaborator Genentech provided an update on its Phase II clinical trial plans for GDC-0449. GDC-0449 is an orally-administered small molecule antagonist of Hedgehog signaling and is being developed pursuant to the parties' June 2003 collaboration agreement. Genentech also announced that it has seen partial responses in advanced basal cell carcinoma tumors in the ongoing Phase I clinical trial of GDC-0449. Curis anticipates that Genentech will present the Phase I data at an upcoming scientific conference.

Genentech stated that it plans to initiate three Phase II clinical trials of GDC-0449 in 2008, which include a trial in metastatic colorectal cancer during the first quarter of 2008 and trials in advanced basal cell carcinoma and in an undisclosed advanced solid tumor of epithelial origin during the second half of 2008.

"We are pleased that our collaborator Genentech has announced its plans to advance this Hedgehog antagonist into broad Phase II clinical testing. We are also very encouraged by Genentech's report of partial responses observed in advanced basal cell carcinoma in the ongoing Phase I clinical trial since we believe such responses provide early evidence of clinical activity with this molecule, which could potentially represent a way to block Hedgehog signaling in cancers that utilize the Hedgehog pathway," said Curis President and CEO Dan Passeri. "We look forward to updating you on these Phase II trials and also to sharing the broader Phase I data."

In connection with the treatment of the first patient in the Phase II colorectal cancer trial, Curis has the right to receive a $3 million cash milestone payment from Genentech. Curis also has the right to receive an additional $3 million cash payment upon initiation of the Phase II testing of the undisclosed advanced epithelial solid tumor. As announced previously, Curis has already received a $3 million cash milestone payment for the initiation of Phase II testing in advanced basal cell carcinoma. Curis received this payment upon initiation of an expansion cohort of the Phase I clinical trial in advanced basal cell carcinoma in October 2007, because Genentech had determined the Phase I expansion cohort satisfied the criteria for a Phase II clinical trial under the parties' collaboration agreement. Curis is eligible to receive additional payments upon the achievement of further development milestones in this indication.
