“Results from earlier clinical trials have been very encouraging,” said David Rowe, VP Development at ParaPRO.  “Our goal now is to evaluate the safety, and efficacy of our product in a larger and more geographically diverse patient population.  Results to date suggest that this product might provide significant benefits to parents, children, and health providers.”

Spinosad (pronounced "spin-OH-sid") is derived through the fermentation of a naturally occurring organism.  Spinosad has been registered by Dow AgroSciences for crop protection use in more than 30 countries and has been recognized by regulatory agencies such as the U.S. Environmental Protection Agency (EPA) for its efficacy on insect pests, low mammalian toxicity and low environmental impact.  In 2002, Spinosad was approved by the National Organics Standards Board for use in the production of “certified organic” foods.  ParaPRO licensed the worldwide rights to Spinosad from Eli Lilly and Company in 2002 to develop and market the compound for the control of lice in human health.

Head lice (Pediculosis capitis) infestation is common in the United States among children 3 to 12 years of age.  According to the American Academy of Pediatrics approximately 6 to 12 million children have infestations each year.  One study estimated that in 1998, 12 to 24 million school days were lost due to lice outbreaks.  Estimates for combined direct and indirect costs to control head lice in the United States may be as high as $1 Billion per year.

ParaPRO announced recently that the company had received a $2.1 million grant from the state of Indiana’s 21st Century Research and Technology Fund to partially finance the phase 3 trials.  The company hopes to complete the trials and submit a new drug application (NDA) to the FDA in 2008.

ParaPRO LLC was founded in 2002 when SePRO Corporation of Carmel, IN purchased the worldwide rights to develop and market Spinosad for the control of lice in human health from Eli Lilly and Company. The compound is currently in clinical trials at multiple sites across the United States. More information on ParaPRO can be found at
