ORGANIZATION AND BUSINESS ACTIVITIES

NOTE 1. ORGANIZATION AND BUSINESS ACTIVITIES

 

Protalex, Inc., a Delaware corporation, (“we,” “us,” “our,” the “Company” or “its”) is a development stage company which has been engaged in developing a class of biopharmaceutical drugs for treating autoimmune inflammatory diseases. Our lead product, PRTX-100, is formulated with highly-purified staphylococcal protein A, which is an immune modulating protein produced by bacteria. The Company does not anticipate generating operating revenue for the foreseeable future.

 

The Company maintains an administrative office in Summit, New Jersey and currently outsources all of its product development and regulatory activities, including clinical trial activities, manufacturing and laboratory operations to third-party contract research organizations and facilities.

 

In April 2009, the Company ceased all operations and terminated all employees in light of insufficient funds to continue its clinical trials and related product development. The Company’s business was dormant until new management took control of its operations in November 2009 following the change in control transaction more fully described below. The Company is currently actively pursuing the commercial development of PRTX-100 for the treatment of rheumatoid arthritis (RA).

 

On December 8, 2010, the Company effected a reverse stock split of the outstanding shares of its common stock, with par value of $0.00001 per share (“Common Stock”), on the basis of one share of Common Stock for each five shares of Common Stock outstanding. Unless otherwise noted, all references in these financial statements and notes to financial statements to number of shares, price per share and weighted average number of shares outstanding of Common Stock prior to this reverse stock split have been adjusted to reflect the reverse stock split on a retroactive basis.

 

PRTX-100 has demonstrated effectiveness in animal models of autoimmune diseases as well as demonstrated activity on cultured human immune cells at very low concentrations, although the effectiveness of PRTX-100 shown in pre-clinical studies using animal models may not be predictive of the results that the Company would see in future human clinical trials. In August 2010, the Company commenced a multi-center Phase 1b clinical trial of PRTX-100 in South Africa in adult patients with active RA on methotrexate. The RA Study was a proof of concept study to evaluate safety and potential efficacy of PRTX-100 in patients with active RA and was approved to enroll up to 40 patients in four dose escalating cohorts. In January 2012, the Company completed patient dosing in the fourth cohort of the RA Study. A total of 37 patients were enrolled in four cohorts ranging from 0.15 μg/kg to 1.50 μg/kg of PRTX-100 or placebo, administered weekly for four weeks. Safety and disease were evaluated over 16 weeks following the first dose. The RA Study results demonstrated that PRTX-100 was generally safe and well-tolerated in patients with active RA at all dose levels. More patients in the 0.90 mg/kg and 1.50 mg/kg cohorts showed improvement in their CDAI (Clinical Disease Activity Index for RA) than did patients in the lower dose or placebo cohorts. The safety, tolerability, and pharmacokinetics (PK) of PTRX-100 in humans have now been characterized in four clinical studies.

 

In November 2012, the Companyannounced enrollment and dosing of the first patient in the U.S. for its new multicenter Phase 1b randomized, multiple-dose, dose-escalation study (the “New Study”) of PRTX-100 in adults with active RA.

 

The primary objective of the New Study will be to assess the safety and tolerability of intravenous PRTX-100 administered weekly over five weeks in patients with active RA on methotrexate therapy. The secondary objectives include determining the effects of PRTX-100 on measures of disease activity, assessing the immunogenicity and evaluating the PK parameters after repeated doses, and determining possible relationships between the immunogenicity of PRTX-100 and safety, PK and efficacy parameters.

 

The sequential dose escalation phase of the New Study is expected to enroll up to 40 patients into the dose escalation cohorts starting at 1.50 μg/kg of PRTX-100 or placebo, and may be followed by up to 12 additional randomized patients for cohort expansion. Enrollment is expected to take place at study sites in both the U.S. and South Africa.

The Company currently has no products on the market.
