Company Background

Celek Pharmaceuticals is addressing the need for new medicines to help patients suffering from cancers that are poorly served by current therapies. The company’s strategy is to enhance the value of in-licensed drug candidates by advancing them through proof-of-concept clinical trials. Formed as a Delaware LLC in 2009, Celek’s two founders, Graham Allaway, Ph.D., and Gary Robinson, Ph.D., are currently the sole employees. 

Technology Overview

Celek’s lead product, CEL-031, is a clinical-stage targeted anticancer drug that selectively induces apoptosis in tumor cells by inhibiting cyclic GMP phosphodiesterases, which are overexpressed in human tumors. Currently in preclinical development for non-muscle invasive bladder cancer (NMIBC), CEL-031’s mechanism of action involves the degradation of β-catenin, a cell signaling protein that plays a key role in bladder cancer tumorigenesis. In clinical studies against advanced cancers, orally-administered CEL-031 showed evidence of efficacy and a good safety profile. CEL-031 should have greater clinical efficacy against NMIBC, where it will be administered intravesically (i.e., instilled transurethrally), the standard drug delivery route for this indication. 

Market Potential

Bladder cancer is the fifth most common cancer in the U.S., with 70,000 new cases annually and 600,000 individuals living with the disease. Worldwide, there are approximately 400,000 new cases annually and the incidence is rising. 

About 70 percent of new bladder cancer diagnoses are made at the non-muscle invasive stage. Current NMIBC treatments involve transurethral resection (TUR), often followed by intravesical chemotherapy using non-specific cytotoxic drugs such as mitomycin C, or immunotherapy with Bacillus Calmette Guerin (BCG). These treatments often fail, with five-year recurrence and progression rates of 50-70 percent and 20-30 percent, respectively. Current drugs also cause adverse side-effects and are hazardous to health care workers.

Since NMIBC is a chronic disease requiring lifelong monitoring and treatment, the lifetime cost per patient of treating bladder cancer is the highest of all cancers.

Despite the pressing need, few new drugs are in development for NMIBC. Celek is developing CEL-031 for two NMIBC indications: (i) perioperative administration following TUR, and (ii) BCG-refractory NMIBC. CEL-031’s estimated peak annual sales in these indications range from $510 million to $660 million. 

Competitive Advantage

As the first targeted drug for NMIBC, CEL-031 represents a potential breakthrough in the treatment of patients with this disease. It should be possible to deliver CEL-031 safely at higher, more effective doses than current cytotoxic chemotherapies, resulting in dramatic reductions in rates of recurrence and progression. CEL-031’s favorable safety profile should also result in a substantial increase in the number of patients treated with CEL-031 compared to current drugs.

Financial Overview

Celek has raised more than $700,000 in funding, including investments by the principals and federal and state grants. The NCI awarded Celek a $176,000 Phase I SBIR contract supporting preclinical studies on CEL-031 for NMIBC. Celek is currently seeking to raise $3 million to support preclinical studies of CEL-031 in bladder cancer and acute myeloid leukemia (AML), and the initiation of a Phase I/II clinical trial in non-muscle invasive bladder cancer. 

Intellectual Property

Celek obtained exclusive rights to CEL-031 from OSI Pharmaceuticals. CEL-031 as a composition of matter and methods of treating cancer with CEL-031 are covered by four issued U.S. patents (plus foreign equivalents). Additional patents cover analogs, methods of identifying anticancer compounds and combination therapies. 

Commercialization Strategy

Celek plans to complete a proof-of-concept clinical trial of CEL-031 in NMIBC patients, then partner for later stage development/commercialization. Recent partnering deals in this therapeutic area have had attractive financial terms. Celek has already met with potential partners who indicated interest in the product. 

Pipeline Products

Celek is also developing CEL-031 to treat advanced cancers using novel formulation and delivery technologies to increase concentrations of the drug in the body, thereby maximizing efficacy. The company is focusing on: (i) advanced bladder cancer, and (ii) acute myeloid leukemia (AML). A recently published independent study reported that CEL-031 has potent activity against tumor cells from AML patients, including those resistant to current drugs, and recommended clinical testing of CEL-031 against AML. CEL-031 would be eligible for Orphan Drug status in this indication.

Management Team

Graham Allaway, Ph.D., President and C.E.O, has spent 22 years in the biotechnology industry. As founding CEO of Panacos Pharmaceuticals, he played a key role in building that company from a private venture-backed start-up to a public company, while raising more than $125 million in private and public equity financing. Dr. Allaway also led Panacos’ drug discovery and development programs. Prior to Panacos, Dr. Allaway was CEO of Manchester Biotech and he previously led therapeutic R&D at Progenics Pharmaceuticals. 

Gary Robinson, Ph.D., Chief Business Officer, has 20 years of experience in research, development, and commercialization of technologies and products in the physical and life sciences. Most recently, he was Senior Director of Business Development at Panacos Pharmaceuticals, where he led partnering, contracting, intellectual property and pre-launch marketing activities. Prior to Panacos, Dr. Robinson held business and corporate development positions at IGEN.
