Earlier, FDA had granted PrevOnco orphan drug status in August 2008, and in March 2010, additionally, NexMed has filed its investigational new drug (IND) application for the product candidate.
NexMed noted that in IND review communication, the FDA has given NexMed the opportunity to move PrevOnco directly into a Phase 3 trial that would support marketing approval, subject to positive study results.
In order to pursue this regulatory path, NexMed would need to expand the proposed Phase 2 study design to use PrevOnco in combination with Doxorubicin as a second-line therapy for patients who have failed Nexavar, the currently marketed anticancer treatment for patients with either HCC or advanced renal cell carcinoma (cancer of the kidney).
NexMed also said that PrevOnco incorporates lansoprazole, which is the generic anti-ulcer compound approved under the name Prevacid and marketed in the US by Takeda Pharmaceuticals North America.
In-vitro and in-vivo data generated to date has demonstrated the ability of lansoprazole to inhibit tumor cell growth and enhance survival in mouse models of cancer alone, and in combination with Doxorubicin.
Bassam Damaj, president and CEO of NexMed, said: “We are very pleased that the FDA agreed with our protocol for the HCC Phase 2 trial for PrevOnco as a first-line therapy for HCC. Additionally, we are actively assessing the suggestion made by the FDA to move directly into a Phase 3 trial, by studying PrevOnco in combination with Doxorubicin as a second-line therapy for patients who have failed Nexavar therapy.
“Following this path could be very advantageous for NexMed since advancing the drug directly into a Phase 3 study would save us at least 12-24 months in development time.”
