September 27, 2018

NEW YORK and LONDON, Sept. 27, 2018 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (NASDAQ:AKTX), a biopharmaceutical company focused on the development and commercialization of innovative therapeutics to treat orphan autoimmune and inflammatory diseases where complement and or leukotriene systems are implicated, today announced its financial results for the second quarter ended June 30, 2018.

“We made several important advancements since the beginning of 2018 and now have a diversified clinical portfolio with four ongoing disease programs and up to a $20 million funding facility provided by Aspire Capital Fund, LLC,” commented Clive Richardson, Interim Chief Executive Officer of Akari Therapeutics.

Clinical development highlights and upcoming milestones

# Coversin clinical trials focused on orphan diseases mediated by both the complement and leukotriene pathways: ° Phase II trial in patients with bullous pemphigoid, a severe blistering skin disease, with initial data expected in the first quarter of 2019 ° Phase I/II trial in patients with atopic keratoconjunctivitis, a sight threatening surface of the eye condition, with initial data anticipated in the first quarter of 2019 # Coversin clinical trials in orphan diseases in which complement dysregulation is the primary disease driver: ° Phase III trial in naïve patients with paroxysmal nocturnal haemoglobinuria (PNH) and a Phase II trial in patients with PNH who are resistant to eculizumab ° Phase II trial in atypical haemolytic syndrome, a severe thrombotic microangiopathy # All patients who completed phase 2 have opted to enroll into the Coversin long term Phase III safety study. Currently there is over 15 years of safety data on Coversin with no drug related severe adverse events to date.

Second Quarter 2018 Financial Results and Business Highlights

# Operating expenses, which include research and development (R&D) expenses and general and administrative (G&A) expenses, were $8.0 million in the second quarter of 2018, as compared to $7.3 million in the same quarter the prior year. Operating expenses for the six months ended June 30, 2018 were $12.3 million, as compared to $15.6 million for the same period the prior year. ° R&D expenses in the second quarter of 2018 were $5.1 million, as compared to $3.8 million in the same quarter the prior year. The increase was due primarily to higher manufacturing costs for Coversin as the Company manufactured clinical trial material for supply through 2019. ° G&A expenses in the second quarter of 2018 were $2.9 million, as compared to $3.6 million in the same quarter last year. This decrease was due primarily to lower legal fees, partially offset by higher rent expense. # Total other expense for the second quarter of 2018 was $43,000, as compared to total other income of $7.0 million in the second quarter of 2018. This change was primarily attributed to a $7.0 million gain in fair value of the stock option and warrant liabilities in the second quarter of 2017, compared to a $153,000 loss in the second quarter of 2018. # Net loss for the second quarter of 2018 was $8.0 million, compared to a net loss of $0.3 million for the same period in 2017. This year over year increase in net loss was due primarily to the aforementioned $7.0 million gain in fair value of the stock option and warrant liabilities in the second quarter of 2017. # The Company has entered into a Securities Purchase Agreement of up to $20 million with Aspire Capital Fund, LLC (“Aspire Capital”). Under the terms of this agreement, Aspire Capital has committed to purchase up to $20 million of Akari’s American Depositary Shares (ADSs) at Akari’s request from time to time during a 30-month period beginning on the effective date of a registration statement related to the transaction and at prices based on the market price at the time of each sale. As consideration for Aspire Capital’s obligation under the Agreement, Akari issued 30,000,000 ordinary shares at $0.02 per ordinary share (equivalent to $2.00 per ADS) to Aspire Capital as a commitment fee and sold to Aspire Capital 25,000,000 ordinary shares at $0.02 per share (equivalent to $2.00 per ADS). # As of June 30, 2018, the Company had cash of $15.1 million, as compared to cash of $28.1 million as of December 31, 2017

About Akari Therapeutics

Akari is a biopharmaceutical company focused on developing inhibitors of acute and chronic inflammation, specifically for the treatment of rare and orphan diseases, in particular those where the complement system or leukotrienes or both complement and leukotrienes together play a primary role in disease progression. Akari’s lead drug candidate Coversin™ is a C5 complement inhibitor currently being evaluated in paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). In addition to its C5 inhibitory activity, Coversin independently and specifically inhibits leukotriene B4 (LTB4) activity. Akari is currently evaluating Coversin in two conditions, the skin and eye diseases bullous pemphigoid and atopic keratoconjunctivitis, where the dual action of Coversin on both C5 and LTB4 may be beneficial. Akari is also developing other tick derived proteins, including long acting versions.
