Osteologix Presents Phase 2 Osteoporosis Data at a Major European Medical Conference

SAN FRANCISCO--(BUSINESS WIRE)--May 27, 2008 - Osteologix, Inc. (OTCBB: OLGX), a specialty pharmaceutical company, announced today that data from a Phase II clinical study of NB S101 (strontium malonate) was presented at the European Calcified Tissue Society's 35th Annual Meeting in Barcelona, Spain.

The presentation entitled "Effect of Three Doses of Strontium Malonate (NB S101) on Markers of Bone Turnovers and Bone Mineral Density: The STRONG Study" demonstrated that the Company's lead osteoporosis drug candidate, NB S101 (strontium malonate), was well-tolerated and significantly suppressed bone resorption while simultaneously improving bone mineral density (BMD) at 12 weeks.

The data highlighted the following:

-- All three doses of NB S101 (0.75g, 1.0g, 2.0g) were safe and well tolerated with the frequency and types of adverse events comparable to those with the active comparator, Protelos(R) (strontium ranelate).

-- Bone resorption assessed with the CTX-1 marker indicated a dose-dependent effect of NB S101 to reduce bone resorption

-- All three doses of NB S101 achieved statistically significant reductions in CTX-1, with the 2 gram dose of NB S101 achieving significantly greater reductions of CTX-1 (p less than 0.001) than the 2 gram dose of Protelos(R)(strontium ranelate).

-- All three doses of NB S101 significantly increased BMD as measured at the total hip and lumbar spine.

   New Publication Highlights Bone Formation Capability of NB S101

In related news, the Company reported the e-publication of a peer-reviewed article in the journal Analytical and Bioanalytical Chemistry. The paper, authored by Anders C. Raffalt, Jens E. T. Andersen, of the Department of Chemistry, Technical University of Denmark and Stephan Christgau, highlights the bone formation potential of the Dual Acting Bone Agent (DABA), NB S101 (strontium malonate). The publication entitled "Application of inductively coupled plasma-mass spectrometry (ICP-MS) and quality assurance to study the incorporation of strontium into bone, bone marrow, and teeth of dogs after one month of treatment with strontium malonate",reveals that after four weeks of treatment with strontium malonate, Bone Specific Alkaline Phosphatase (BSAP), a well validated marker of bone formation, significantly increased with a strong correlation to the bone-strontium content. In females, the placebo-treated group showed a decrease in BSAP of 53%, whereas the three strontium malonate-treated groups showed an increase of 60%, 276%, and 278% for the groups treated with 300, 1000, and 3000 mg/kg/day, respectively. For males the corresponding values were -44%, +142%, +194%, and +247% increases in BSAP in the placebo, 300, 1000, and 3000 mg/kg/day groups respectively.
