NEW YORK (TheStreet) -- Shares of Hasbrouck Heights, NJ-based Nymox Pharmaceuticals (NYMX) - Get Nymox Pharmaceutical Corp Reportwere jumping 42.39% to $3.46 on heavy trading volume mid-Wednesday afternoon after the company's long-term trial for an enlarged prostate (BPH) and prostate cancer drug, fexapotide, was successful.

The study analyzed results from 391 patients who were given double-blind placebo injections followed by a crossover to either fexapotide or conventional treatments. Participants' BPH symptoms were monitored and analyzed over the following two to three years.

Nymox reports that 82% to 95% of patients who received fexapotide in the crossover did not need surgery as compared with patients who received conventional treatments.

"Fexapotide shows significant efficacy against prostate cancer as a therapeutic, and in addition has been shown to reduce the risk of prostate cancer when fexapotide is used to treat BPH," CEO Paul Averback said in a company statement.
