MONTREAL, CANADA--(Marketwired - Sept. 18, 2013) - Theratechnologies Inc. (TSX:TH) announced today that EMD Serono voluntarily notified the United States Food and Drug Administration (FDA) about an upcoming shortage of tesamorelin in the United States.

EMD Serono has notified the FDA that, after conducting a review of all available supply, EMD Serono estimates a drug shortage will start to occur in mid-October with a complete stock-out by mid-November.

To reduce the duration of the shortage, EMD Serono will implement a mitigation plan.

EMD Serono also informed the FDA that lots of tesamorelin are scheduled to be manufactured at the end of September to facilitate drug supply replenishment, which should start by mid-December 2013.

As announced earlier this year, production of tesamorelin was halted using the NDA approved manufacturing process to rectify issues that were not linked to the product itself but rather related to the consistency of the lyophilization cycle. Corrective measures were developed and implemented and production resumed in May 2013. Quality issues were recently encountered with the revised manufacturing process and it was decided to carry out further development work. Until process improvement measures are completed, production will be resumed using the current NDA approved manufacturing process to produce drug product for the U.S. market.

This forward-looking information includes, but is not limited to, information regarding the timing of the availability of new lots of EGRIFTA™ for resale, the capacity to meet market demand from the available inventory, the optimization of the manufacturing process and the submission to the FDA of such optimized manufacturing process.

Forward-looking information is based upon a number of assumptions and is subject to a number of risks and uncertainties, many of which are beyond Theratechnologies' control that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. These assumptions include, but are not limited to, the fact that the lots of EGRIFTA™ manufactured with the NDA approved manufacturing process will meet the product specifications and will be available for resale by mid-December 2013, no event will occur delaying the beginning or preventing the completion of the manufacture of new lots of EGRIFTA™, current sales level will remain stable such that the inventory level will be high enough to meet market demand until mid-October 2013 or until new lots of EGRIFTA™ are available for resale, the Company will be able to optimize its manufacturing process and the FDA will not object to the use of the NDA approved manufacturing process to resume the manufacture of EGRIFTA™.

These risks and uncertainties include, but are not limited to, the risk that a drug-shortage occurs because there is a delay in resuming or during the manufacture of EGRIFTA™, the lots of EGRIFTA™ manufactured with the NDA approved manufacturing process are not within the specifications and may not be available for resale by mid-December 2013, demand for EGRIFTA™ increases and the inventory level is not large enough to supply such demand, the FDA does not accept that the Company resumes the manufacture of EGRIFTA™ with the NDA approved manufacturing process and/or the risk that the Company is unable to optimize its manufacturing process if the lots manufactured from the NDA approved manufacturing process fails to be within the specifications and are not available for resale.
