Quarterly information as of September 30, 2013

• Reinforcement of cash reserves thanks to the capital increase in July
• Livatag® Relive clinical trial (Phase III): Recruitment ongoing and good safety profile confirmed
• Validive® clinical trial (Phase II): Active recruitment for results in 2014

Paris, November 14, 2013 - BioAlliance Pharma SA (Euronext Paris - BIO), an innovative Company dedicated to the development of orphan oncology products and to supportive care products, today published the major key milestones achieved during the third quarter of 2013.

July was marked by a successful capital increase which enabled the Company to raise a net amount of €8.4 million and showed strong support from its shareholders, specifically the two largest, Financière de la Montagne and IDInvest. This transaction was strongly oversubscribed and has significantly reinforced the cash reserves amounting to €15.1 million as of September 30, 2013.

In parallel, BioAlliance Pharma has achieved major milestones in the development of its two key programs (Orphan Oncology Products portfolio):

• ReLive Phase III trial (Livatag ® ) evaluating the efficacy of Livatag® in the treatment of primary liver cancer: recruitment is on track and strongly increasing with to date more than 80 patients screened in about 20 sites in France, and confirmation of the product's good tolerance profile validated by the third Data and Safety Monitoring Board meeting (DSMB, committee of independent experts). The European study's extension is ongoing in 6 countries (Spain, Italy, Russia, Hungary, Austria and Belgium) and the study should be extended to the US in 2014, enabling the end of recruitment in 2015 with results expected in 2016. This drug represents a key growth potential for the Company.
• Phase II trial with Validive ® in the prevention of chemoradiation therapy-induced oral mucositis in patients with head and neck cancer: international expansion of recruitment (Europe, United States) with more than 75% of recruitment completed to date and creation of an international Advisory Board in charge of optimizing the product's development strategy. The recruitment should be completed beginning of 2014 for results expected in the second part of that year.

BioAlliance Pharma has associated the best worldwide experts in the area to each of its two products, Livatag® and Validive® , to ensure the clinical and regulatory relevance of the Company's development options in indications where the current lack of available treatment requires new therapeutic approaches.

Furthermore, BPIfrance has recognized the innovation brought by Livatag® with the grant of €9 million in funding to the NICE (Nano Innovation for Cancer) consortium (with €4.3 million directly allocated to BioAlliance as leader of the consortium) whose purpose is to build a pioneer platform dedicated to nanomedicines.

Moreover, BioAlliance Pharma has reinforced the protection of Sitavig® with the grant of two new patents in the United States and in South Korea. The product's market exclusivity is thus guaranteed until 2029 in major international territories and represents an additional asset to sign an agreement with commercial partners.

At last, outside any new license agreement, the consolidated turnover for the third quarter 2013 stood at €246,000 and amounted to €1.1 million over the first 9 months.

"The third semester of 2013 was devoted to the international expansion of our two clinical trials in an increasing number of leading hospitals", declared Judith Greciet, CEO of BioAlliance Pharma. "The trial with Validive® is approaching its completion with results expected in 2014, a critical year for the product's and the Company's valorization. Our capital increase achieved beginning of the third semester has enabled us to reinforce our cash reserves. Active discussions are ongoing to secure a partnership agreement on Sitavig® which should represent a new source of revenue to face the next steps over the coming months".

• Next DSMB (Data Safety Monitoring Board) scheduled Q2 2014

Validive®

End of recruitment of the Phase II clinical trial planned H1 2014 with preliminary results expected H2 2014
