DARA BioSciences Announces the Acquisition of Exclusive North American Rights to Oravig(R) (Miconazole Buccal Tablets 50mg), From Onxeo S.A.


March 10, 2015 - Raleigh, NC

RALEIGH, NC--(Marketwired - March 10, 2015) - DARA BioSciences, Inc. (NASDAQ: DARA), an oncology supportive care specialty pharmaceutical company dedicated to providing healthcare professionals a synergistic portfolio of medicines to help cancer patients adhere to their therapy and manage side effects arising from their cancer treatments, today announced that it has finalized a Commercialization Agreement with Onxeo S.A., an innovative company specializing in the development of orphan oncology drugs, granting DARA the U.S. rights to Oravig®, the first and only orally-dissolving buccal tablet approved for oral thrush. DARA has contemporaneously executed a co-promotion agreement with Mission Pharmacal Company, a privately held pharmaceutical company based in San Antonio, Texas, to co-promote Oravig in the primary care market.

Under the terms of the Agreement, DARA will acquire the approved New Drug Application (NDA) and will have the exclusive rights to market and sell Oravig in the United States. DARA also has the right to pursue regulatory approval in Canada which, if granted, would give DARA exclusive rights to market and sell Oravig there. DARA will book all revenues on Oravig and will pay Onxeo S.A. certain milestone payments upon the achievement of defined sales thresholds; DARA has additionally undertaken to complete a pediatric study as part of a post-marketing commitment, which if successful, may provide DARA with both an expanded indication and market size for Oravig.

"We are extremely excited to add an approved, branded, and unique product to our oncology supportive care portfolio," stated Christopher G. Clement, DARA CEO and President. "Combined with our current portfolio of products, Gelclair® for oral mucositis and Aquoral® for dry mouth, Oravig provides DARA the opportunity to offer a distinctive therapeutic armamentarium for patients suffering from side effects of the oral cavity due to their cancer treatments. We look forward to promoting this exciting new product in conjunction with our trusted partners at Mission."

There are more than three million prescriptions written in the U.S. annually for oral thrush, with the majority of these written in the primary care segment. In order to maximize the commercial opportunity for Oravig, DARA has signed an agreement with Mission Pharmacal to promote Oravig in the primary care market. DARA currently in-licenses two products from Mission Pharmacal for promotion exclusively within the Oncology market: Aquoral for dry mouth and Ferralet® 90 for anemia. Additionally DARA's field sales organization is contracted through Alamo Pharma services, a subsidiary of Mission Pharmacal.

"Our partnership with DARA is extremely important to us," stated Terry Herring, Mission Pharmacal President. "We are committed to providing important products across the various patient populations we serve. Oravig allows Mission to add a significant therapeutic to our primary care division's promoted product portfolio, while further strengthening and expanding upon our existing relationship with the DARA team."

Oravig is an approved product in the U.S. market and was previously promoted by third parties.

"Topical localized therapies for oropharyngeal candidiasis are available; unfortunately these therapies are not optimal due to the need for dosing several times a day, short contact time of the active agent with the oral mucosa, sugar content which can promote yeast growth, unpleasant taste, and difficulty of use in patients with a dry mouth or oral ulceration. Together, these limitations contribute to reduced compliance and efficacy of these topical agents, often necessitating the use of systemic agents which have increased side-effects for patients," stated Dr. Rajesh V. Lalla, Section of Oral Medicine, University of Connecticut Health Center. "Oravig provides an excellent localized therapy solution for the treatment of oropharyngeal candidiasis because Oravig adheres to the oral mucosa and provides sustained local release of miconazole over a period of several hours with just one daily application," Dr. Lalla concluded.

DARA is planning to launch Oravig later this year.

Locust Walk Partners, a transaction advisory firm for the biopharmaceutical industry, served as exclusive advisor to Onxeo.

About DARA BioSciences, Inc.
DARA BioSciences Inc. of Raleigh, North Carolina, is an oncology supportive care pharmaceutical company dedicated to providing healthcare professionals a synergistic portfolio of medicines to help cancer patients adhere to their therapy and manage side effects arising from their cancer treatments.

DARA holds exclusive U.S. marketing rights to both Soltamox® (tamoxifen citrate) oral solution and Gelclair®. DARA licensed the U.S. rights to Soltamox® from UK-based Rosemont Pharmaceuticals, Ltd., a U.K. based manufacturer and a subsidiary of Perrigo Company plc, and Gelclair® from the Helsinn Group in Switzerland. Under an agreement with Innocutis, DARA also markets Bionect® (hyaluronic acid sodium salt, 0.2%).

Soltamox® (tamoxifen citrate) oral solution, the only liquid form of tamoxifen, is indicated for the treatment of metastatic breast cancer, the adjuvant treatment of node-positive breast cancer in premenopausal women, the reduction in risk of invasive breast cancer in women with ductal carcinoma in situ (DCIS), and for the reduction of the incidence of breast cancer in women at high risk for breast cancer. Currently, there are more than 1.8 million prescriptions of tamoxifen written on an annual basis in the United States. Between 30 and 70 percent of patients fail to complete their prescribed course of treatment, thereby diminishing its benefits in reducing the risk of breast cancer recurrence.

Tamoxifen Important Safety Information
Tamoxifen citrate is contraindicated in women who require concomitant coumadin-type anticoagulant therapy, in women with a history of deep vein thrombosis or pulmonary embolus, and in women with known hypersensitivity to the drug or any of its ingredients.

Serious and life-threatening events associated with tamoxifen in the risk reduction setting (women at high risk for cancer and women with DCIS) include uterine malignancies, stroke and pulmonary embolism.

The most common adverse reactions to tamoxifen treatment are (incidence > 20%) hot flashes, fluid retention, vaginal discharge, vaginal bleeding, vasodilatation, nausea, irregular menses, weight loss, and musculoskeletal events.

Tamoxifen carries the following Boxed Warning:

WARNING -- For Women with Ductal Carcinoma in Situ (DCIS) and Women at High Risk for Breast Cancer: Serious and life-threatening events associated with tamoxifen in the risk reduction setting (women at high risk for cancer and women with DCIS) include uterine malignancies, stroke and pulmonary embolism. Incidence rates for these events were estimated from the NSABP P-1 trial (see CLINICAL PHARMACOLOGY, Clinical Studies, Reduction in Breast Cancer Incidence In High Risk Women). Uterine malignancies consist of both endometrial adenocarcinoma (incidence rate per 1,000 women-years of 2.20 for tamoxifen vs. 0.71 for placebo) and uterine sarcoma (incidence rate per 1,000 women-years of 0.17 for tamoxifen vs. 0.0 for placebo)*. For stroke, the incidence rate per 1,000 women-years was 1.43 for tamoxifen vs. 1.00 for placebo**. For pulmonary embolism, the incidence rate per 1,000 women-years was 0.75 for tamoxifen versus 0.25 for placebo**. Some of the strokes, pulmonary emboli, and uterine malignancies were fatal. Health care providers should discuss the potential benefits versus the potential risks of these serious events with women at high risk of breast cancer and women with DCIS considering tamoxifen to reduce their risk of developing breast cancer. The benefits of tamoxifen outweigh its risks in women already diagnosed with breast cancer.

*Updated long-term follow-up data (median length of follow-up is 6.9 years) from NSABP P-1 study. See WARNINGS, Effects on the Uterus-Endometrial Cancer and Uterine Sarcoma in Prescribing Information.
**See Table 3 under CLINICAL PHARMACOLOGY, Clinical Studies in Prescribing Information.

The full Prescribing Information for Soltamox is available at www.soltamox.com/prescribing-information.

Gelclair® is an alcohol-free bio adherent oral rinse gel for rapid and effective relief of pain associated with oral mucositis caused by chemotherapy and radiation treatment. Gelclair should not be used by patients with a known or suspected hypersensitivity to the product or any of its ingredients. DARA licensed the U.S. rights to Soltamox from UK-based Rosemont Pharmaceuticals, Ltd., and Gelclair from the Helsinn Group in Switzerland. Under an agreement with Innocutis, DARA also markets Bionect® (hyaluronic acid sodium salt, 0.2%) a topical treatment for skin irritation and burns associated with radiation therapy, in U.S. oncology/radiology markets. Bionect should not be used by patients with known hypersensitivity to any of its ingredients. For further information on Gelclair and Bionect and the Full Prescribing Information please visit www.Gelclair.com and www.Bionect.com.

DARA is focused on expanding its portfolio of oncology supportive care products in the United States, via in-licensing and/or partnering of complementary late-stage and approved products. In addition, the company wishes to identify a strategic partner for the clinical development of KRN5500, currently in Phase 2 for the treatment of chronic, treatment refractory, chemotherapy-induced peripheral neuropathy (CCIPN). The FDA has designated KRN5500 as a Fast Track Drug, and has granted DARA two separate Orphan Drug Designations for the treatment of multiple myeloma and for the treatment of painful, chronic chemotherapy-induced peripheral neuropathy that is refractory to conventional analgesics (CCIPN).

In early 2014, DARA kicked off its new partnership with Alamo Pharma Services, a subsidiary of Mission Pharmacal, in deploying a dedicated 20-person national sales team in the U.S. oncology market. In addition to promoting DARA's products Soltamox, Gelclair and Bionect, this specialized oncology supportive care sales team also provides clinicians with access to two Mission Pharmacal products: Ferralet® 90 (for anemia), and Aquoral® (for chemotherapy/radiation therapy-induced dry mouth).
