HENDERSON, Nev.--(BUSINESS WIRE)--
Spectrum Pharmaceuticals, Inc. (NasdaqGS:SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in Hematology and Oncology, announced today the Company has enrolled the first patient in a Phase 3 trial of Qapzola, a potent tumor-activated drug being investigated for low and intermediate risk non-muscle invasive bladder cancer. Under the SPA, this trial will evaluate the intravesical use of Qapzola in patients with non-muscle invasive bladder cancer (NMIBC), as a single instillation 60 ± 30 minutes, following transurethral resection of the bladder tumor (TURBT).
“Qapzola is being developed for low-to-intermediate risk non-muscle invasive bladder cancer for which there are no approved drugs in the 21st century,” said Rajesh C. Shrotriya, MD, Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. “This is a novel drug that becomes cytotoxic only when it encounters hypoxic tumor such as non-muscle invasive bladder cancer. Bladder tumors are rich in DT-diaphorase, an enzyme that converts Qapzola into an alkylating agent that leads to cell death. One of the key challenges in the treatment of bladder cancer is a significantly high recurrence rate which leads to exorbitant costs and high patient morbidity. It is estimated that the cost of treatment of this disease will surpass $5 billion by 2020. The design of the current trial incorporates learnings from previous studies, feedback from leading KOL’s as well as from the FDA. I believe, Spectrum’s pipeline has never been as exciting as it is today. In addition to aggressive development of Qapzola, we expect to file a registration application (BLA) with the FDA for Rolontis in 2018 and we are very excited with the early data we are seeing with Poziotinib, our novel irreversible tyrosine kinase inhibitor.”
In accordance with the SPA, the Phase 3 trial is a randomized, double-blind, placebo-controlled, multi-center trial that will enroll patients with low and intermediate risk NMIBC as per the American Urology Association (AUA) Guidelines. The new study design with a reduced sample size from 1557 to about 425 patients will significantly shorten the duration of this trial. The protocol includes a single instillation of Qapzola 60 ± 30 minute post-TURBT, to avoid inactivation of Qapzola by blood that is present after surgery. The patients will be randomized 2:1 to receive either 8 mg instillation of Qapzola or placebo post-TURBT. Following one instillation of study drug and a safety follow-up at Day 35, subsequent follow up visits will be conducted until tumor recurrence or end of study, whichever occurs first. The primary endpoint for this trial is Time to Recurrence.
About Bladder Cancer
According to the National Cancer Institute, bladder cancer is the fifth most common malignancy in the US with 79,030 new cases of bladder cancer expected in 2017, and currently over 500,000 patients living with the disease. Due to high recurrence rates, intensive surveillance strategies, and expensive annual treatment costs, bladder cancer has the highest lifetime cost per patient of all cancers, and an overall cost estimated at around $3.4 billion. Non-muscle invasive bladder cancer (NMIBC) is a form of bladder cancer that is localized in the surface layers of the bladder and has not invaded or spread to the deeper muscle layer. Approximately 70% of all patients newly diagnosed with bladder cancer have NMIBC. Urologists treat the disease predominantly by transurethral resection of the bladder tumor(s) (TURBT); in the U.S., there are approximately 300,000 TURBT procedures every year to treat bladder cancer. Because of the high recurrence rates, both professional urology associations and NCCN Guidelines recommend instillation of a cytotoxic agent following TURBT for NMIBC, although in the U.S., there are no FDA-approved agents for this indication.
About Special Protocol Assessments
A Special Protocol Assessment is a written agreement between a Sponsor and the U.S. Food and Drug Administration on the design, execution and analysis for a clinical trial that may form the basis of a new drug application, or NDA. Final marketing approval depends upon the efficacy results, safety profile and an evaluation of the risk/benefit of treatment demonstrated in the Phase 3 clinical program.
