News Releases

Princeton, NJ – November 10, 2016 – Soligenix, Inc. (OTCQB: SNGX (Soligenix or the Company), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today its recent accomplishments and financial results for the third quarter ended September 30, 2016.

Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix stated, “We continue to be very encouraged with the positive results demonstrated in our Phase 2 oral mucositis trial with SGX942 (dusquetide) and recently announced the publication of these results in the Journal of Biotechnology. These data demonstrate the promising potential of our IDR technology platform in the treatment of oral mucositis but also the potential of this technology to expand into other indications, such as infectious disease.  Based on our ongoing discussions with the regulatory agencies in both the US and Europe, we anticipate having a pivotal Phase 2b/3 study design of SGX942 during the first half of next year. We also continue to actively enroll patients in our pivotal Phase 3 study in cutaneous T-cell lymphoma with SGX301 (synthetic hypericin).”

Schaber continued, “We were also very pleased with the expansion of our partnership with SciClone Pharmaceuticals for the development of SGX942 in China and other markets in Asia.  SciClone will be responsible for all aspects of development and commercialization in the territories having access to data generated by Soligenix. Their upfront investment in Soligenix further demonstrates the promising potential of this innovative technology.”

Soligenix Recent Accomplishments:

•  On September 12, 2016, the Company announced an exclusive license agreement granting rights to SciClone Pharmaceuticals, Inc. to develop, promote, market, distribute and sell SGX942 (dusquetide), our novel, first-in-class therapy being developed for the treatment of oral mucositis in patients with head and neck cancer, in China as well as Taiwan, South Korea and Vietnam. In exchange for exclusive rights, Soligenix will receive royalties on net sales and supply commercial drug product on a cost-plus basis. Under the terms of the agreement, SciClone made an upfront equity investment in Soligenix of $3 million.
