FDA approval and trials are e x p e n s i v e... Check this out. They are going 4 orphan drug status 2 cut the costs. Cheapest would be $20 million. Upside here is great imo.

Business Overview


The Company is developing RP-323 for the treatment of Hodgkin’s lymphoma (HL), Acute Myelogenous Leukemia (AML), and to cause elevation of white blood cells (WBC) in patients depleted of these elements due to various conditions.

The Technology

The priority drug development efforts of the Company are focused on the use of RP-323, a naturally occurring compound that has a number of properties that are uniquely suited for the treatment of patients with Hodgkin’s lymphoma (HL), and Acute Myelocytic Leukemia (AML). Company scientists had worked with RP-323 in the laboratory for many years studying its ability to convert cancer cells to normal cells, a process called differentiation. It was also observed in some instances to cause cancer cell death. These observations were the basis of the proposal to test RP-323 in relapsed AML patients in China and later in the US and resulted in findings that were sufficiently encouraging to support further interest in this drug to treat AML. During the course of these preliminary clinical studies RP-323 was found to be extremely potent in causing a marked and favorable increase in white blood cells (WBC) in blood, key elements in fighting infections. These results were also observed in cancer patients whose WBC were depleted due to the toxic effects of chemotherapeutic drugs used during the course of their therapy. Later, in a US phase I safety study conducted at Cancer Institute of NJ (CINJ), it was discovered the use of RP-323 in HL when a patient’s tumor was reduced by 2 cm.

Clinical Studies in Acute Myelocytic Leukemia

Based on the known properties of RP-323, it was first administered in a pilot study in China, either alone or in combination with standard drugs, and caused temporary remission of AML in some patients’ refractory to standard therapy. Several patients recovered sufficiently with RP-323 treatment to return to their normal occupations, symptom-free. Interest in these findings led to a Phase 1 investigator-sponsored trial in 35 patients by a leading oncologist at a leading cancer hospital in New Jersey, the University of Medicine and Dentistry of New Jersey (UMDNJ). This study determined the maximum tolerated dose of RP-323 and described its relatively mild side effects. The results of this Phase 1 trial led to interest by the same investigator to initiate a Phase 2 study. The use of RP-323 in treatment of refractory AML is expected to qualify for a “fast track” designation at the United States Food and Drug Administration (FDA), and the Company expects to apply for “orphan drug” status. An “orphan drug ” is a pharmaceutical agent that has been developed specifically to treat a rare medical condition, the condition itself being referred to as an orphan disease. The Company’s clinical plans are expected to result in completion of the required clinical studies in 2016 and provide a basis for market approval for the treatment of AML.


The Company estimates the budget for reaching market approval for the treatment of AML to be $40 million. However, should the Company be able to obtain “orphan drug” status from the FDA, the budget would be reduced to $20 million. All plans are subject to the Company obtaining adequate financing, or partnering with a third party, to fund the cost of the studies. The Company cannot provide any assurances that it will be able to obtain such financing or partnering arrangement.




Clinical Results in Elevation of White Blood Cells


Clinical studies in over 100 cancer patients demonstrated the potent ability of RP-323 to stimulate the production of white blood cells (WBC) and neutrophils. Both the treatments for various diseases and the disease themselves can result in extremely low numbers of these elements. Their elevation is essential to prevent post-treatment infections common to these patients. In comparative studies in animals, RP-323 is significantly more potent than marketed drugs used for this purpose. The effect of RP-323 on the elevation of these and other blood elements will be measured during treatment of AML.

Hodgkin’s Lymphoma

Hodgkin’s lymphom is a cancer that is found most frequently in two different age groups: 15 – 35 and over 55, and occurs in both sexes although it is more common in males and individuals with HIV. The overall incidence of Hodgkin’s lymphoma is approximately 2.7 per 100,000 persons. Malignant Reed Sternberg cells invade and destroy the architecture of the lymph nodes and infiltrate major organs such as the liver and spleen. Radiation and chemotherapy are used routinely but these treatments can later result in morbidity and mortality as a result of causing second malignancies. More effective and safer treatments are needed for this disease.

Market Opportunities


AML

It is estimated that 40,000 people in the US have AML and an additional 14,000 are diagnosed annually with a yearly death rate of over 10,000. Based on this incidence, the potential market for RP-323 for the treatment of AML is approximately $1 to 2 billion peak sales annually in the US and more than $5 billion worldwide.

White Blood Cell

Currently marketed drugs for elevating key infection-fighting blood elements are used in supportive cancer care, inflammation, nephrology and bone disease. In 2012, this market exceeded $3 billion. The clinical use of RP-323 for these purposes is expected to have several key therapeutic advantages over marketed drugs, along with a clean safety profile and observed high efficacy is expected to result in a 15 to 30 percent market share and peak annual sales of $0.5 to $1 billion. Amgen would be the Company’s largest competitor in this market.

HL

In the U.S. 185,793 suffer from Hodgkin's lymphoma (2011); the worldwide market potential for Hodgkin's lymphoma is estimated to be $1-2 billion.

Patent

The Company has been assigned United States Patent No. 6,063,814, entitled “Phorbol esters as anti-neoplastic and white blood cell elevating agents,” and utility patent application titled “Compositions and Methods of Use Of Phorbol Esters For The Treatment of Neoplasms (Acute Myeloid Leukemia).” The patent is intended to provide the Company with exclusive rights to the use of intravenous RP-323 for therapeutic purposes. Provided that the Company can obtain additional funding, the Company intends to expand its patents through the addition of indications for use and adding protection in appropriate countries.

Government Regulations

The research, pre-clinical development, clinical trials, product manufacturing and marketing which may be conducted by the Company is subject to regulation by the FDA and similar health authorities in foreign countries. The proposed products and technologies of the Company also may be subject to certain other federal, state and local government regulations, including, without limitation, the Federal Food, Drug and Cosmetic Act, and their state, local and foreign counterparts. Although there can be no such assurance, the Company does not believe that compliance with such laws and regulations has, nor is presently expected to have, a material adverse effect on the business of the Company. However, the Company cannot predict the extent of the adverse effect on its business or the financial and other cost that might result from any government regulations arising out of future legislative, administrative or judicial action.

Generally, the steps required before a pharmaceutical or therapeutic biological agent may be marketed in the United States include: (i) pre-clinical laboratory tests, in vivo pre-clinical studies in animals, toxicity studies and formulation studies; (ii) the submission to the FDA of an IND application for human clinical testing, that must become effective before human clinical trials commence; (iii) adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug; (iv) the submission of a marketing application to the FDA; and (v) FDA approval of the marketing application prior to any commercial sale or shipment of the drug.

Pre-clinical studies include laboratory evaluation of the product, conducted under Good Laboratory Practice (GLP) regulations, and animal studies to assess the pharmacological activity and the potential safety and effectiveness of the drug. The results of the pre-clinical studies are submitted to the FDA in the IND. Unless the FDA objects to an IND, it becomes effective 30 days following submission and the clinical trial described in the IND may then begin.

Every clinical trial must be conducted under the review and oversight of an institutional review board (IRB) at each institution participating in the trial. The IRB evaluates, among other things, ethical factors, the safety of human subjects, and the possible liability of the institution.
