Effective October 1, 2008, OrthoLogic Corp. began doing business as Capstone Therapeutics (the “Company” or “we”); on May 21, 2010 the name of the Company was changed from OrthoLogic Corp. to Capstone Therapeutics Corp. The OTCQB ticker symbol is “CAPS” and the website is www.capstonethx.com.
Capstone Therapeutics Corp. is a biotechnology company committed to developing a pipeline of novel peptides and other molecules aimed at helping patients with under-served medical conditions. Previously, we were focused on the development and commercialization of two product platforms: AZX100 and Chrysalin (TP508). Since March 2012, we no longer have any interest in or rights to Chrysalin. In 2012 we wound down internal operations, ceased clinical development of AZX100 in dermal scarring, formerly our principal drug candidate, and moved to a more virtual operating model. In 2014, we terminated the License Agreement for AZX100 intellectual property and returned all interest in and rights to the AZX100 intellectual property to the Licensor (AzTE).
On August 3, 2012, we entered into a joint venture, LipimetiX Development, LLC, (the “JV”) to develop Apo E mimetic peptide molecule AEM-28 and its analogs. The JV has a development plan to pursue regulatory approval of AEM-28, or an analog, as treatment for Homozygous Familial Hypercholesterolemia (granted Orphan Drug Designation by FDA in 2012) and other hyperlipidemic indications. The initial development plan extended through Phase 1a and 1b/2a clinical trials and was completed in the fourth quarter of 2014. The clinical trials have a safety primary endpoint and an efficacy endpoint targeting reduction of cholesterol and triglycerides.
The JV received allowance from regulatory authorities in Australia permitting the JV to proceed with the planned clinical trials. The Phase 1a clinical trial commenced in Australia in April 2014 and the Phase 1b/2a clinical trial commenced in Australia in June 2014. The clinical trials for AEM-28 are randomized, double-blinded, placebo-controlled studies to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of six escalating single doses (Phase 1a in healthy patients with elevated cholesterol) and multiple ascending doses of the three highest doses from Phase 1a (Phase 1b/2a in patients with hyper-cholesterolemia and healthy subjects with elevated cholesterol and high Body Mass Index). The Phase 1a clinical trial consisted of 36 patients and the Phase 1b/2a consisted of 15 patients. Both clinical trials were completed in 2014 and the Medical Safety Committee, reviewing all safety-related aspects of the clinical trials, observed a generally acceptable safety profile. As first-in-man studies, the primary endpoint was safety; yet efficacy measurements analyzing pharmacodynamics yielded statistical significance in the pooled dataset favoring AEM-28 versus placebo in multiple lipid biomarker endpoints.

Concurrently with the development activities with AEM-28, the JV has performed limited pre-clinical studies that have identified an analog of AEM-28, referred to as AEM-28-02, and a new phospholipid formulation, that has the potential of equivalent efficacy, higher human dose toleration and an extended composition of matter patent life (application filed in 2014 with the U.S. Patent and Trademark Office).
The JV and Company intend to explore fundraising, partnering or licensing to obtain additional funding to continue development activities of AEM-28 and AEM-28-02.
The JV and the Company do not have sufficient funding at this time to continue additional material development activities of AEM-28 and its analogs. The JV may conduct future clinical trials in Australia, the USA, and other regulatory jurisdictions if regulatory approvals, additional funding, and other conditions permit. The JV may also fund research or studies to investigate AEM-28-02 and for treatment of acute coronary syndrome and other indications.
The Company intends to limit its internal operations to a virtual operating model while continuing monitoring and participating in the management of LipimetiX Development LLC’s AEM-28 and analogs development activities and maintaining the required level of corporate governance and reporting required to comply with Securities and Exchange Commission rules and regulations.
