Metabolic's Obesity Trial Update: First 100 Subjects Complete the Phase 2B Trial of AOD9604
Thursday October 5, 10:08 am ET
- The first 100 subjects have now completed the Phase 2B OPTIONS Study including 24 weeks of daily oral dosing of obesity drug, AOD9604
- The last subject will complete the trial ahead of schedule in December 2006 with results expected to be announced in March 2007
MELBOURNE, Australia, Oct. 5 /PRNewswire-FirstCall/ -- Metabolic Pharmaceuticals (Metabolic) (ASX: MBP / OTC Bulletin Board: MBLPY) announced today that the first 100 subjects have completed the Phase 2B OPTIONS Study for obesity drug, AOD9604. The OPTIONS Study is designed to assess weight loss at lower doses of AOD9604 than previously tested.
The OPTIONS Study reached full recruitment with 536 subjects ahead of schedule in late April this year and as a result, the study will also finish ahead of schedule, in December 2006. The OPTIONS Study includes 24 weeks of randomised double-blind drug or placebo treatment, with the primary endpoint of weight loss at 12 weeks. More than 100 subjects have already completed the full 32-week protocol, and all remaining subjects will have completed the trial in December 2006. Metabolic expects to announce the results of the study in March 2007, once the database is finalised, the blind is lifted and the data analysed.
Dr Roland Scollay, CEO of Metabolic, commented, "we are very pleased with the clinical progress of our obesity drug. AOD9604 has shown no negative side effects in studies completed so far and is the only obesity drug in advanced development with a primarily metabolic mode of action. Furthermore, the previous study showed no evidence of the post-treatment weight rebound that is typical of other weight loss drugs. The potential commercial benefits of these competitive advantages are significant."
Background to AOD9604 and obesity
-- AOD9604 is an orally active, 16-amino acid, peptide drug, based on a
fragment of human Growth Hormone (hGH).
-- AOD9604 has undergone numerous safety and tolerability checks through
human clinical trials, and a previous Phase 2 efficacy trial
demonstrated a very competitive 2kg weight loss more than placebo over
a 12 week period, as well as other benefits such as improved
cholesterol profile.
-- The drug's competitive advantages are its good safety and side effect
profile and its novel mechanism of action - AOD9604 addresses
metabolism (fat burning) rather than acting as an appetite suppressant.
-- The current global market for prescription obesity drugs is estimated
at approximately US$1 billion a year with very high growth forecast,
estimated to reach US$10-30 billion a year if safe and effective weight
loss drugs become available.
Previous announcements regarding this trial, made on 18 October 2005, 23 January 2006, 2 May 2006 and 19 July 2006 are available at

Appendix: the OPTIONS Study trial design
Number of subjects: 536 subjects enrolled, approximately
equal number of men and women
Subject selection criteria: - BMI* (Body Mass Index) 30-45 kg/m2;
- Age 18-65 years; and
- A waist circumference of more than
102 cm for males and 95 cm for females,
in otherwise healthy subjects.
Expected completion date: Last subject will complete the study in
December 2006, results expected in March
2007
Blinding status: Double-blinded (neither treating doctor,
nor subject, nor Metabolic knows whether
the subject is receiving drug or placebo)
Placebo controlled: Yes (one group receives only placebo -- a
tablet that looks the same as AOD9604
but has no drug content)
Treatment route: Oral (tablets)
Treatment frequency: Once per day
Dose level: Dose groups of 0, 0.25, 0.5 and 1 mg
(the 0 group is the placebo group)
Primary end points: - Weight loss over 12 weeks of treatment
for any one of three daily AOD9604 oral
doses of 0.25 mg, 0.5 mg and 1 mg
compared to placebo; and
- Safety and tolerability.
Secondary end points: - Weight loss over 24 weeks of treatment;
- Comparison of the effects of the three
different dose levels;
- Waistline reduction over 24 weeks of
treatment;
- Body fat reduction assessed by whole
body scans; and
- Improvement in risk factors such as
glucose control and lipid profiles over
24 weeks of treatment.
Trial sites: 16 clinical trial sites throughout
Australia

About Metabolic
Metabolic Pharmaceuticals Limited (ASX: MBP, NASDAQ OTC: MBLPY) is a Melbourne based, ASX listed biotechnology company with 285 million shares on issue. The Company employs 24 staff and is led by an experienced and proven management team. Metabolic's main focus is to take innovative drugs, with large market potential, through formal preclinical and clinical development. Metabolic's expertise in drug development has resulted in two high value drugs in advanced human clinical development, namely:
-- AOD9604 -- an obesity drug currently in a Phase 2B trial with results
expected in March 2007;
-- AOD9604 -- additional use in osteoporosis with a Phase 2 trial
expected to commence in 2007; and
-- ACV1 -- a neuropathic pain drug currently in Phase 2A trials.
These drugs address multi-billion dollar markets which are poorly served by existing treatments. In addition to its lead drugs, Metabolic has an exciting research pipeline with drugs targeting type 2 diabetes (ADD) and nerve regeneration (NRPs). Metabolic is also developing a platform to enable oral delivery of existing injected peptide drugs, a technology which has already shown proof-of-concept. This has high potential for use by other companies developing peptide drugs and could foster multiple out-licensing deals.
Metabolic plans to license its lead drugs to a global partner following Phase 2 trials and will continue to utilise its clinical development expertise to drive future company growth and profits.

Background information on the drug development process
The steps required before a drug candidate is commercialised include:
1. Discovery or invention, then filing a patent application in Australia
and worldwide;
2. Pre-clinical testing, laboratory and chemical process development and
formulation studies;
3. Controlled human clinical trials to establish the safety and efficacy
of the drug for its intended use;
4. Regulatory approval from the Therapeutic Goods Association (TGA) in
Australia, the FDA in the USA and other agencies throughout the world;
and
5. Marketing and sales.
The testing and approval process requires substantial time, effort, and financial resources and we cannot be certain that any approvals for any of our products will be granted on a timely basis, if at all.
Human clinical trials are typically conducted in three sequential phases
which may overlap:
Phase 1 Phase 2 Phase 3
