Fax - Response to Duramed’s IND (b)(4), Amendment #9, May 3, 2005 - Adenovirus

Memo to:         Gabriel Lebovic, Ph.D.

Director of Regulatory Affairs
Duramed Research
 
From:             Daryll Miller, M.A.
                        Regulatory Health Project Manager
                        FDA/CBER/OVRR/DVRPA
 
Date:              May 3, 2005
 
Regarding:     Response to Duramed’s IND (b)(4), Amendment #9
 
Recommendation: Reproductive toxicology studies with adenovirus vaccines types 4 and 7 are currently not feasible due to lack of an animal model (i.e., strains only replicate in human host). Thus, performing these studies would very unlikely produce any useful data. The safety of live adenovirus vaccines previously manufactured by Wyeth in pregnant individuals has not been established. Evidence in the literature that infection of human pregnant subjects with wild-type adenovirus (unknown strain) leads to placental infection and adverse fetal outcomes needs further clarification/investigation. However, precautions against becoming pregnant are in place for vaccinees, and advice against pregnancy in spouses or co-domiciles are in place in the present Phase I study. The vaccine studied under IND (b)(4) should be contraindicated for use in pregnant women. For the purpose of future licensure of the product, vaccinees and spouses or co-domiciles who inadvertently become pregnant during the time of the study should be followed in a pregnancy registry to collect relevant data.
