ET -- SOUTH SAN FRANCISCO, Calif., Nov. 16 /PRNewswire-FirstCall/
-- Poniard Pharmaceuticals, Inc. (NASDAQ:PARD) today announced that
its pivotal Phase 3 SPEAR (Study of Picoplatin Efficacy After
Relapse) trial of picoplatin in the second-line treatment of small
cell lung cancer (SCLC) did not meet its primary endpoint of
overall survival. The analysis, based on 320 evaluable events
(patient deaths), showed a hazard ratio of 0.82 with a p value of
0.089. "We are disappointed that the trial did not meet the primary
endpoint. The data indicates that more patients on the best
supportive care arm received chemotherapy following progression
than those on the picoplatin arm, and we believe that this may have
been a significant factor contributing to the trial outcome, as
picoplatin appeared to demonstrate a trend toward a survival
advantage. Based on these findings and other analyses, we are
contacting the FDA today to request a meeting to discuss a
regulatory path forward. We look forward to presenting the full
SPEAR efficacy and safety data at an upcoming medical conference
early next year," said Jerry McMahon, Ph.D., chairman and chief
executive officer of Poniard. "We believe that the SPEAR data,
coupled with efficacy and safety data from more than 1,100 cancer
patients treated with picoplatin and the proof-of-concept data from
our trials in colorectal, prostate and ovarian cancers, support our
continued partnering effort. Our focus will be on the regulatory
pathway for picoplatin, partnering activities, and realigning the
use of resources for these objectives." Conference Call and Webcast

international, multi-center, randomized, controlled Phase 3 SPEAR
trial was conducted under a Special Protocol Assessment (SPA) with
the U.S. Food and Drug Administration (FDA). The trial evaluated
the efficacy and safety of picoplatin as second-line therapy in 401
cancer patients with SCLC who were refractory to or who progressed
within six months of first-line platinum-based therapy. Picoplatin
administered as an intravenous infusion once every three weeks plus
best supportive care (BSC) was compared to BSC alone. BSC was
designed in accordance with the National Comprehensive Cancer
Network's guidelines. The primary endpoint of the trial was overall
survival. Other endpoints included overall response rate,
progression-free survival, disease control rate and duration of
response. The Statistical Analytical Plan of the trial, as agreed
to in the SPA, was 90 percent powered to show a 33 percent
reduction in risk in death for picoplatin treatment plus best
supportive care (BSC) compared with BSC alone (hazard ratio of
0.67; p value of 0.05). Patient enrollment in the trial was
completed in March 2009. About Picoplatin Picoplatin is a new and
differentiated platinum-based chemotherapeutic agent that is in
clinical development for multiple cancer indications, treatment
combinations and by two routes of administration. It is designed to
overcome platinum resistance associated with chemotherapy in solid
tumors. Study data to date suggest that picoplatin has an improved
safety profile relative to existing platinum-based cancer
therapies. More than 1,100 patients have received picoplatin.
Results obtained to date suggest that hematologic events are common
but manageable. Kidney toxicity (nephrotoxicity) and nerve toxicity
(neurotoxicity) are less frequent and less severe than is commonly
observed with other platinum chemotherapy drugs. Picoplatin has
demonstrated anti-tumor activity in a variety of solid tumors. In
addition to the SPEAR Phase 3 trial in SCLC, Poniard is evaluating
intravenous picoplatin in a Phase 2 clinical trial in patients with
colorectal cancer, in a Phase 2 clinical trial in patients with
castration-resistant prostate cancer, and in a Phase 1 cardiac
safety assessment. In addition, final results from a trial of an
oral formulation of picoplatin were presented earlier this year.
