MENLO PARK, Calif.,  February  8, 2016— Corium International, Inc. (Nasdaq: CORI), a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, today announced unaudited financial results from operations for the first fiscal quarter ended December 31, 2015.  Corium’s fiscal year ends on September 30.

Recent Corporate Developments

· Reported Positive Topline Interim Results from Corplex™ Donepezil Phase 1 Pharmacokinetics Clinical Trial —This transdermal product candidate is designed to deliver donepezil (the active ingredient in once-daily oral Aricept®) in a once-weekly patch for the treatment of Alzheimer's disease.  The study met each of its objectives, which included demonstrating sustained and controlled pharmacokinetics (PK) comparable to the daily oral administration of Aricept, and acceptable safety and skin tolerability.  These results provide a solid basis for advancing Corplex Donepezil into further clinical development.

· Completed dosing in Phase 1 PK study of Corplex™ Memantine —Conducted in parallel with the Phase 1 trial of Corplex Donepezil, this trial was designed to evaluate Corium's proprietary transdermal candidate for sustained and controlled delivery of memantine (the active ingredient in Namenda®) for the treatment of moderate-to-severe dementia of the Alzheimer's type.  Topline interim results are expected in February.

· Positive results from an initial bioavailability study of once-weekly transdermal aripiprazole  —Conducted by Corium’s collaboration partner, Aequus Pharmaceuticals Inc., this study evaluated once-weekly transdermal delivery of aripiprazole (the active ingredient in once-daily oral ABILIFY®), and the results supported the feasibility of sustained, seven-day delivery of therapeutic doses of the drug.An atypical antipsychotic, aripiprazole isthe leading medication for the treatment of a number of psychiatric disorders including bipolar I disorder, schizophrenia, major depressive disorder and irritability associated with autistic disorder.

· MicroCor®Zolmitriptan product candidate demonstrates rapid delivery in animal studies  —Promising PK data in a pig model demonstratesthe ability of Corium’s MicroCor transdermal technology to deliver zolmitriptan (the active ingredient in ZOMIG®), a leading migraine treatment.  This product candidate is designed to provide rapid onset of quick relief in aneedle-free delivery system for the treatment of acute migraine. The company is currently evaluating formulationswith the goal of advancing into clinical proof of concept studiesin the fourth quarter of calendar year 2016.

“The first quarter has been a particularly productive one for Corium, as we have advanced two product candidates in our CNS portfolio into the clinic, and have worked with our partners in progressing studies that are key to their programs,” said Peter D. Staple, President and Chief Executive Officer of Corium.  “We reported positive topline results of our Corplex Donepezil Phase 1 PK clinical study, which supports our plans for advancing our lead CNS program further in clinical development.  With dosing now complete, we are also looking forward to providing the results of our Phase 1 PK trial of Corplex Memantine.  Our collaboration with Aequus has yielded positive results in a human bioavailability study of aripiprazole, and our partner Agile is progressing in their Phase 3 trial of a  once-weekly contraceptive patch.  Finally, we  are continuing to achieve promising results with the second product candidate in our MicroCor pipeline, including showing very rapid delivery of a leading treatment for migraine headaches in animal studies.  With this portfolio of opportunities, we are accelerating our growth and progress in advancing important new transdermal therapeutics.2016 will be a year of significant milestones for Corium.”

Financial Results for the Quarter Ended December 31, 2015

Corium reported total revenues in the firstquarter of fiscal 2016 of $7.5 million, compared with $9.8 million in the firstquarter of fiscal 2015.The decrease in total revenues primarily resulted from a declinein contract research and development revenues, as well as the decline in product revenues from Fentanyl TDS.The decline in contract research and development revenues is primarily the result of several programs advancing into later stages of clinical development when there are fewer revenue generating development activities until preparations begin for approval and commercial launch.

Total research and development (R&D) expenses in the firstquarter of fiscal 2016 were $7.5million, compared with $7.9 million in the firstquarter of fiscal 2015. The decrease in total R&D expenses primarily reflects the lower level of activities required for contract research and development programs, many of which are in the later stages of development, partially offset by Corium’s increased investment in its proprietary product programs, including the advancement of Corium’s two programs for Alzheimer’s disease,  Corplex Donepezil and Corplex Memantine, into Phase 1 clinical trials.

General and administrative (G&A) expenses in the firstquarter of fiscal 2016 were $3.0 million, compared with $2.7 million in the firstquarter of fiscal 2015. The increase in G&A was primarily attributable to higher personnel costs associated with new employees added in the second half of fiscal 2015.

Corium reported a net loss for the firstquarter of fiscal 2016 of $9.4million, or $0.42 per share, compared with a  net loss of $6.8 million, or $0.37 per share, in the firstquarter of fiscal 2015.As of December 31, 2015, there were 22,219,413 shares of Corium common stock outstanding.

Cash and cash equivalents as of December 31, 2015 were $63.0 million.
