EOquin/ApaziquoneSpectrum Pharmaceuticals, Inc. An International Commercial-Stage Biotechnology Company

Being investigated as intravesical instillation in non-muscle invasive bladder cancer.

Target Indications

Non-Muscle Invasive Bladder Cancer (NMIBC)

apaziquone bladder cancer

Cystoscopic appearance of tumors in the bladder.

Route of Administration

Intravesical Instillation (instilled directly into the bladder)

Mode of Action

Apaziquone/EOquin is a bio-reductive agent activated by reductase enzymes, such as DT-diaphorase, expressed by bladder tumor cells, to form cytotoxic alkylating agents.

apaziquone bladder cancer

A) Bladder tumor before intravesical therapy.
B) In a Phase 2 study, after 6 weekly intravesical instillations of apaziquone, tumor is no longer present.

Status

Single Intravesical Instillation Studies:

Spectrum conducted two multi-center, randomized, double-blind, placebo controlled, Phase 3 pivotal trials of single dose intravesical apaziquone to be instilled into the bladder in the immediate post-operative period after surgical resection of low-risk, non-muscle invasive bladder tumors. The primary endpoints were the rate of tumor recurrence at 2 years between apaziquone and placebo.

These two trials were analyzed individually and did not meet their primary endpoint of a statistically significant difference in the rate of tumor recurrence at 2 years between the two arms.

The Company plans to file an NDA in 2014.

Bladder Cancer

The American Cancer Society estimates that the 2014 incidence of bladder cancer in the United States will be approximately 74,690. As of 2011, SEER estimated the prevalence of the disease to be 571518 in the U.S.

The global prevalence of bladder cancer is estimated at 2.7 million.

Risk factors for bladder cancer include smoking and exposure to certain industrial chemicals. Symptoms may include hematuria, painful or burning urination without evidence of a urinary tract infection, or abdominal pain. If detected early, bladder cancer is a managable disease.

Apaziquone bladder cancer staging

The initial treatment of this cancer is complete surgical removal of the tumor (TURBT). However, bladder cancer is a highly recurrent disease with approximately 80% of patients recurring within 5 years, and a majority of these patients recur within 2 years.

Because bladder cancer patients have a high risk of recurrence, bladder cancer is the most expensive cancer to treat on a per patient lifetime basis. (Botteman et al., Pharmacoeconomics, 2003).
