III. Key events for the first half of 2014

  • On 28 July 2014, AB Science published in the peer-reviewed journal Annals of Oncology, results from a randomized phase 2 study of masitinib in treatment of Gleevec®-resistant gastrointestinal stromal tumor.

This is the publication of the results of the clinical phase 2 study that has supported the application for conditional approval of Masitinib to the European Medicines Agency.
(http://annonc.oxfordjournals.org/lookup/doi/10.1093/annonc/mdu237:
http://annonc.oxfordjournals.org/lookup/doi/10.1093/annonc/mdu237)

Findings showed masitinib to produce a statistically significant overall survival (OS) advantage of 12.4 months in patients with Gleevec®-resistant GIST when compared with Sutent (sunitinib) from Pfizer, which is currently the standard of care for second-line treatment of advanced GIST.
Overall, encouraging survival and safety data from a controlled, randomized trial indicate a positive benefit-risk balance.

An international phase 3 trial of masitinib in patients with Gleevec-resistant/intolerant GIST has been initiated based on these promising results. 

  • On 30 July 2014, AB Science announced the renewal of its Standby Equity Facility (PACEO®) with Société Générale as authorized by the Shareholders' Meeting of June 27, 2014.

Société Générale has committed to purchase newly created shares at any time during the 36-month commitment period, within the global limit of 3,200,000 shares, being 9.7% of the 32,925,187 shares currently outstanding.

Should the entire standby equity facility be drawn down and resulting in the issuance of 3,200,000 new shares, a shareholder who currently owns 1% of the company's share capital would experience a reduction of his / her ownership to 0.96%[1]:

.
For each tranche, the price to be paid equals the volume weighted average share price of the three trading days preceding the effective date of purchase with a discount capped at 5% dependent on the size of the drawdown. This discount allows Société Générale, who is not positioned as a long term shareholder in the Company, to purchase the shares independently of market volatility.

AB Science has no minimum drawdown obligation, and will use the facility at its sole discretion if market conditions are favorable and in the best interests of both the Company and its shareholders.

  • On 30 September 2014, the external Data and Safety Monitoring Board (DSMB) has recommended the continuation of its phase 3 study of masitinib in mastocytosis based upon review of the latest safety and efficacy data. The DSMB was created as part of the Company's pivotal clinical study evaluating masitinib in the treatment of mastocytosis.

This new recommendation corroborates the previous DSMB recommendation to continue this phase 3 study based upon the favorable result of a futility analysis in November 2013. That analysis tested the possibility of masitinib to demonstrate superiority over placebo on the primary analysis as defined in the study protocol.

The objective is this phase 3 study is to compare the safety and efficacy of masitinib with that of placebo in adult patients having smoldering or indolent systemic mastocytosis with severe handicaps/symptoms at baseline.

The final analysis of trial data is still planned for 2015.

Mastocytosis is an orphan disease characterized by an abnormal proliferation of mast cells either in bone marrow only or in several tissues. Mastocytosis comes in two main forms: indolent and aggressive. Indolent mastocytosis can be either cutaneous or systemic. The prevalence of Indolent Systemic Mastocytosis (ISM) is estimated at between 1/40,000 and 1/20,000[2]:
#_ftn2
of the general population. The symptoms and handicaps are severe in about one third of the patients, hence an estimated target population for masitinib ranging from 1/120,000 to 1/60,000 of the general population.

Since the prevalence of Indolent Systemic Mastocytosis is reputed to be comparable across countries, the target population for masitinib could reach an estimated 20,000 adult patients in the world annually.

There is currently no registered treatment in severe systemic mastocytosis.
Masitinib received orphan drug status designation in mastocytosis, both at EMA and FDA.

  • Finally, on 6 October, the external Data and Safety Monitoring Board (DSMB) - which was created as part of the Company's pivotal clinical study evaluating masitinib in the treatment of multiple sclerosis - has recommended the continuation of its phase 3 study of masitinib in primary progressive multiple sclerosis or relapse-free secondary progressive multiple sclerosis based upon review of the latest safety data.

The on-going phase 3 clinical trial is an international, multicenter, randomized, double-blind study comparing the efficacy and safety of masitinib with that of placebo in the treatment of patients with progressive forms of multiple sclerosis. The efficacy analysis is measured by Multiple Sclerosis Functional Composite (MSFC) score, EDSS and quality of life after 96 weeks of treatment.

These results are reassuring because they confirm there are no observed safety concerns with masitinib over a 2-year treatment period.
