PVAX-hSlo is under clinical development by Urovant Sciences and currently in Phase II for Urinary Incontinence. According to GlobalData, Phase II drugs for Urinary Incontinence have a 25% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how PVAX-hSlo’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

PVAX-hSlo overview

pVAX-hSlo (hmaxi-K) gene transfer therapy is under development for the treatment of urinary incontinence. pVAX-hSlo (hmaxi-K) gene is administered by intradetrusor injection, intravesical instillation, intracavernous and intramuscular injection. hmaxi-K gene is a double stranded naked plasmid DNA (nucleic acid) molecule carrying the human cDNA encoding the alpha, or pore forming a subunit of the human smooth muscle maxi-K channel hSlo. hSlo is under control of the CMV promoter positioned upstream of the transgene and the construct also contains the Bovine Growth Hormone poly A site, kanamycin resistance gene and pUC origin of replication.

It was also under development for erectile dysfunction and overactive bladder syndrome.
