Cosmo Pharmaceuticals : FDA Grants Cosmo Pharmaceuticals both QIDP and Fast Track Designations for Aemcolo (Rifamycin SV MMX®)

Aemcolo Eligible for Additional Market Exclusivity and Priority Review in the United States

Drug Candidate Offers Significant Anti-Infective Properties and
Unique Delivery Mechanism for Treatment of Travelers' Diarrhea

Dublin - October 23, 2017- Cosmo Pharmaceuticals N.V. (SIX: COPN) today announced that the U.S. Food and Drug Administration has granted both Qualified Infectious Disease Product (QIDP) and Fast Track designations for Aemcolo (Rifamycin SV MMX), formerly Zemcolo, for the treatment of patients with travelers' diarrhea.

'There have not been any new chemical entities approved to treat colonic infections in years, so resistance to current available drugs is a serious issue. The QIDP and Fast Track designations highlight the importance of treating colonic infections with new chemical entities and Aemcolo's potential to address this unmet medical need,' said Alessandro Della Chà, Chief Executive Officer of Cosmo Pharmaceuticals. 'We look forward to productive interactions with the FDA as we work to bring Aemcolo to patients.'

If approved, Aemcolo will be eligible for an additional five years of market exclusivity based on the QIDP designation under the Generating Antibiotic Incentives Now (GAIN) Act. The GAIN Act is intended to encourage development of new antibiotic drugs for the treatment of serious or life-threatening infections. With Fast Track designation, Aemcolo is now eligible for priority review. Fast track is a process the FDA designed to facilitate the development and expedite the review of new drugs that are intended to treat serious conditions and fill an unmet medical need. The program's purpose is to get important new drugs to the patient earlier.

Phase III clinical trials of Aemcolo in traveler's diarrhea have been completed in the US and EU. The Phase III program demonstrated Aemcolo's superiority as compared to placebo (p-value= 0.0008) and its non-inferiority as compared to Ciprofloxacin.

New Drug and Marketing Authorization Applications are currently being prepared for submission to the FDA and European Medicines Agency (EMA), respectively.

About Aemcolo
Aemcolo is a pharmaceutical product candidate employing rifamycin SV engineered with Cosmo Pharmaceuticals' MMXtechnology. Aemcolo is a broad spectrum, semi-synthetic, orally non-absorbable antibiotic which can be used for the treatment of bacterial infections of the colon such as traveler's diarrhea. The application of MMX technology to rifamycin SV allows the antibiotic to be delivered directly into the colon, avoiding unwanted effects on the beneficial bacterial flora living in the upper portions of the gastro-intestinal tract. The specific dissolution profile of Aemcolo tablets is thought to increase the colonic disposition of the antibiotic so that an optimized intestinal concentration is achieved thus abating its systemic absorption in the small intestine.
