GTx, Inc. (Nasdaq: GTXI) today provided a Company update and reported
financial results for the second quarter of 2012.
"We continue to make progress on our late stage clinical programs. We
are enrolling our two pivotal Phase III clinical trials evaluating
enobosarm for the prevention and treatment of muscle wasting in
non-small cell lung cancer patients," said Mitchell S. Steiner, MD, CEO
of GTx. "We expect to receive topline data from these studies during the
second quarter of 2013. In addition, we will begin screening patients
this month for our Phase II clinical study of Capesaris® as
secondary hormonal therapy in men with metastatic castration resistant
prostate cancer."
Clinical updates
Enobosarm (Ostarine®,
GTx-024), an oral selective androgen receptor modulator, for the
prevention and treatment of muscle wasting in patients with advanced
non-small cell lung cancer: GTx is currently enrolling subjects
with advanced non-small cell lung cancer in two pivotal Phase III
clinical trials, POWER 1 and POWER 2. These international Phase III
studies are being conducted in clinical sites in the United States,
Europe, and South America. In each of the placebo-controlled,
double-blind clinical trials, 300 patients with Stage III or IV
non-small cell lung cancer are being randomized to oral daily doses of
placebo or enobosarm 3 mg at the time they begin first line standard
chemotherapy. The studies are evaluating as co-primary endpoints at
three months of treatment the response rates of enobosarm versus placebo
on maintaining or improving total lean body mass (muscle) assessed by
dual x-ray absorptiometry and improving physical function assessed by
the Stair Climb Test. Durability of the drug effect is being evaluated
as a secondary endpoint after five months of treatment. Enrollment for
both studies is expected to be completed in the fourth quarter of this
year, and topline results should be released during the second quarter
of 2013.
Capesaris® (GTx-758), an
oral selective estrogen receptor alpha agonist, for secondary hormonal
therapy of advanced prostate cancer: GTx is initiating this
quarter an open-label clinical study of 75 men with metastatic
castration resistant prostate cancer to test three lower doses of
Capesaris (125 mg, 250 mg and 500 mg) sequentially in cohorts of 25
patients each. The Phase II 712 clinical trial is designed to assess the
effect of Capesaris on serum prostate specific antigen response and
prostate cancer progression. The study is expected to provide
confirmation of the mechanism of drug action for Capesaris on lowering
serum free testosterone levels by increasing serum SHBG in castrated men
who failed primary androgen deprivation therapy. The safety and
tolerability of lower doses of Capesaris will also be evaluated in these
subjects, including the incidence of venous thromboembolic events.
