Company to Present at BIO CEO in NYC February 11, 2013

THE WOODLANDS, Texas, Feb. 11, 2013 -- (Healthcare Sales & Marketing Network) -- Repros Therapeutics Inc.(R) (RPRX) today provided an update for both of its core clinical programs.

Androxal(R) Six Month Open Label Study (ZA-300)

As part of the FDA requirement for total number of subjects to be exposed for six months, the Company is conducting a 500 subject open label study. To date, the Company has enrolled 499 subjects and expects the study to be fully enrolled this week.

Androxal(R) Pivotal Studies (ZA-301 and ZA-302)

The Company has sent a "request for guidance" letter to the FDA. The key points were:

• The identification of a single high enrolling site with a population whose baseline characteristics appear different from the other sites;
• The Company has proposed enrolling an additional 40 subjects into each of the two pivotal studies to allow for subset analysis while retaining the power of the original protocols;
• The Company proposed moving two sites from the enrolling study ZA-302 to the closed for enrollment study ZA-301.

When the company receives guidance from FDA, it will update the financial community.

Proellex(R)-V

The Company has requested an end of Phase 2 meeting for its vaginal Proellex program for the treatment of uterine fibroids. The request was for a meeting before the end of April 2013.
