VEN 307: Diltiazem Cream Novel Treatment for Anal Fissures

 
 

15 Anal Fissures: Cause and Management Increased sphincter tone Local ischemia Tear (fissure) in anal canal Cause Severe pain on defecation Treatment options Control constipation, topical steroids Reduce sphincter tone Compounded Topical drugs: • GTN* • diltiazem Botox Surgery Sphincters (muscles) Anal fissure 1.1 mm office visits/year Anal fistula * Rectiv (topical GTN) recently approved by FDA but not yet launched

 
 

16 VEN 307 ( diltiazem ) Summary 2% topical diltiazem cream applied peri - anally TID Mechanism of Action » Calcium channel blocker  Relaxes the internal anal sphincter, reducing pain and increasing tissue blood flow Preclinical Safety » Preclinical topical safety with 2% diltiazem twice daily for ninety days Clinical Pharmacology » Topical has < 10% systemic exposure as oral dose but significantly greater effect on sphincter tone – i.e., blood levels do not predict activity. Low exposure = better tolerability than oral diltiazem Clinical Data » Ten clinical trials in 453 individuals » Infrequent mild AEs reported » Similar or better reduction in pain, significantly better tolerability than GTN

 
 

17 Pivotal Phase III Trial » FDA (analgesia division) pre - IND meeting conducted in August 2007  Achieved clarity on primary endpoint: reduction in pain  Confirmed safety database and tox requirement  NDA filing possible 2013 » Phase III trial conducted by SLA (Ex - NA licensor)  3 arms, 155 pts per arm: 2% 4% diltiazem TID , and placebo in 31 sites in Europe  Primary endpoint: reduction in pain on defecation using a validated scale ( Likert , NRS)  Ventrus review of blinded data and study operations 10/2011: Correct patients enrolled, data compliance and GCRP are good, data are being reviewed continuously  Enrollment completed; data readout expected in May 2012 » Planned Second Phase III trial(s):  Developing 4 possible extended release formulations: may test some or all in human manometry trial in 2012. Next phase could be 2 PH III trials with extended release formulation if one is acceptable, or 1 with original formulation
