First-Half 2017

• Two strategic partnerships completed validating the platform and the pipeline
• Major investment by Tasly Pharmaceutical
   
• Target confirmed: first marketing authorization of PXT3003 in the second half of 2019

Paris, France, 7:30 pm, 19 October 2017 (CEST) - Pharnext SA (FR00111911287 - ALPHA), a biopharmaceutical company pioneering a new approach to the development of innovative drugs based on the combination and repositioning of known drugs, today announced its first-half 2017 financial results.

Daniel Cohen, M.D., Ph.D. Co-Founder and CEO said of activity for the first half of 2017: "Activity in the first-half of the year was very dense; we implemented two prominent strategic partnerships with the biotech company Galapagos and the Tasly Group, one of the top ten pharmaceutical companies in China. Our flagship product, PXT3003 for the treatment of Charcot-Marie-Tooth disease type 1A, is nearing the end of Phase 3, which is slated for the second half of 2018. We confirm our target of taking the product to market by 2019."

A half-year marked by strategic agreements

In March 2017, Pharnext signed its first R&D partnership with Galapagos NV for the creation of a new pipeline of pre-clinical combinations. This agreement relies on Pharnext's drug research and development platform: PLEOTHERAPY(TM). The working programme involves several therapeutic indications particularly in inflammatory diseases.

In May 2017, Pharnext also signed a major strategic agreement with Tasly Pharmaceutical, a group in the top 10 of listed Chinese pharmaceutical companies. This agreement is for a EUR20 million investment by Tasly in Pharnext and the creation of a Joint-Venture (JV) for research and development, 30% owned by Pharnext, to develop new combinations between chemical molecules and drugs produced by modernised Chinese traditional medicine. This partnership also includes a licensing agreement for the JV to market the drug candidate PXT3003 for CMT1A on the Chinese market.

Continuation of the clinical trial for PXT3003 in Charcot-Marie-Tooth disease type 1A (CMT1A) with a first date set year-end 2017

During the first half of 2017, Pharnext continued the Phase 3 clinical trial of PXT3003, PLEODRUG^TM candidate, for the treatment of CMT1A. Patient enrolment was completed in compliance with the established roadmap.

An important step is expected by the end of 2017 with the results of the adaptive design and futility analysis.
The aim of the adaptive design analysis is to determine whether or not more patients should be added to the study. The futility analysis helps determine whether to continue or discontinue the trial, based on the observed efficacy of the first patient sample (100/300).

High visibility at large international events

Along with ongoing R&D efforts, there was an increased presence at major international scientific meetings dedicated to orphan and neurodegenerative diseases, and to the repositioning of drugs:

• In late March 2017, Pharnext presented new synergy data in Vienna, Austria, at the 13^th International Conference on Alzheimer's and Parkinson's diseases and related neurological disorders. In pre-clinical models of Alzheimer's disease, PXT864 enhanced the efficacy of standard therapeutic treatments.
   
• In late June 2017, the R&D PLEOTHERAPY(TM) platform was presented during the 6^th Annual Conference on "Drug Repositioning, Repurposing and Rescue" in Chicago, United States. This presentation also gave Pharnext the opportunity to provide more specific information on its business model and growth strategy for the coming years.
   
• In early July 2017 in Sitjes, Spain, a status update of the pivotal Phase 3 clinical trial for PXT3003 in CMT1A was presented during an oral presentation and on a poster at the 2017 Peripheral Nerve Society Meeting.
   
• In mid-July 2017 in London, United Kingdom, new synergy data on PXT864 in Alzheimer's disease were also presented at the Alzheimer's Association International Conference 2017.
   
• In early September 2017, a status update of the pivotal Phase 3 trial of PXT3003 was also presented as a poster at the 2017 American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) in Phoenix, United States.

From now until the end of the year, Pharnext will participate in major international events where it will have the opportunity to spotlight the clinical development of PXT3003 and PXT864 to the global medical and scientific community. For instance, the company will give a presentation at the CMT Patient Summit of the Hereditary Neuropathy Foundation (HNF). This will be held in Boston, United States, on 3 November. The company will also take part in the CTAD (Clinical Trial on Alzheimer's Disease) conference in Boston, United States, from 1-4 November.

H1 2017 Financial Results

⁽¹⁾ The H1 2017 financial statements were approved by the Board of Directors at their meeting on 19 October 2017. They were subject to a limited review by the Statutory Auditors. The half-year financial report is available on the Company's website: https://www.pharnext.com/en/investors/

The increase in R&D spending is related to the development of Phase 3 trials with PXT3003 on Charcot-Marie-Tooth disease (CMT 1A).

The operating loss at 30 June 2017 was -EUR9.3 million, compared to -EUR5.6 million one year earlier.

Post-closing, the agreements signed with Tasly Pharmaceuticals had several financial impacts in July, with the income from a restricted capital increase, a EUR5 million cash contribution (EUR4.9 million issue premium) and a EUR15 million convertible bond issuance.

Restated for these two transactions, pro forma cash assets at the end of June 2017 after the Tasly Group's investment, amount to EUR26.1 million.
