November 15, 2018

-- Four ongoing clinical trial programs -- Two clinical programs expected to report initial data in first quarter 2019 -- Long-term clinical study continues to yield encouraging safety data

NEW YORK and LONDON, Nov. 15, 2018 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (NASDAQ:AKTX), a biopharmaceutical company focused on innovative therapeutics to treat orphan autoimmune and inflammatory diseases where complement and or leukotriene systems are implicated, today announced its financial results for the third quarter ended September 30, 2018.

“We are focused on moving our four priority clinical programs forward and expect initial data from our trials in patients with bullous pemphigoid (BP) and atopic keratoconjunctivitis (AKC) in the first quarter of 2019,” 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 with initial data readouts expected in the first quarter 2019: ° Phase II trial in patients with BP, a severe blistering skin disease ° Phase I/II trial in patients with AKC, a sight-threatening surface of the eye condition # Coversin clinical trials in orphan diseases in which complement dysregulation is the primary disease driver: °Two trials open in PNH: a Phase III trial in naïve patients and a Phase II trial in patients who are resistant to eculizumab ° An open Phase II trial in atypical hemolytic syndrome (aHUS), a severe thrombotic microangiopathy ° Ongoing named patient program in pediatric patients with thrombotic microangiopathy (TMA) post bone marrow transplant # Long-term safety study for Coversin °Total cumulative number of patient-years on Coversin treatment approximately 15 years ° All patients in the long term study have now been treated for more than 15 months and the first patient has now been treated for 34 months ° No drug related serious adverse events and no neutralizing antibodies reported to date ° Six PNH patients were transfusion dependent prior to treatment with Coversin, of which four in the long-term study are now transfusion independent; two remain on transfusion.

Third Quarter 2018 Financial Results

# Research and development (R&D) expenses in the third quarter of 2018 were $3.3 million, as compared to $6.4 million in the same quarter the prior year. The decrease was due primarily to lower manufacturing costs for Coversin as the Company had previously manufactured clinical trial material for supply through 2019, partially offset by higher clinical trial activity. # General and administrative (G&A) expenses in the third quarter of 2018 were $2.4 million, as compared to $2.2 million in the same quarter last year. This increase was due primarily to higher professional fees. # Operating expenses were $3.0 million in the third quarter of 2018. Excluding a $2.7 million one-time litigation settlement gain, operating expenses were $5.7 million in the third quarter of 2018, as compared to $8.5 million in the same quarter the prior year. This decrease is primarily due to lower R&D expenses. # Total other expense for the third quarter of 2018 was $0.6 million, as compared to $1.8 million in the same quarter the prior year. This change was primarily attributed to a $0.7 million loss in fair value of the stock option liabilities in the third quarter of 2018, compared to a $1.7 million loss in the third quarter of 2017. # Net loss for the third quarter of 2018 was $3.6 million, compared to a net loss of $10.4 million for the same period in 2017. This year over year decrease in net loss was due primarily to the aforementioned $2.7 million litigation settlement gain, lower R&D expenses and change in fair value of the stock option and warrant liabilities, which were lower in the third quarter of 2018 compared to the prior year period. # As of September 30, 2018, the Company had cash of $10.1 million, as compared to cash of $28.1 million as of December 31, 2017. # In addition, on September 26, 2018, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with Aspire Capital Fund, LLC (“Aspire Capital”), which provides that, upon the terms, Aspire Capital is committed to purchase up to an aggregate of $20.0 million of the Company’s ADSs over the 30-month term of the Purchase Agreement. In consideration for entering into the Purchase Agreement, concurrently with the execution of the Purchase Agreement, the Company issued 30,000,000 ordinary shares to Aspire Capital and sold to Aspire Capital 25,000,000 ordinary shares for $0.02 per share (equivalent to $2.00 per ADS and $500,000).

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 (C5) or leukotriene (LTB4) systems, or both complement and leukotrienes together, play a primary role in disease progression. Akari’s lead drug candidate, Coversin, is a C5 complement inhibitor that also independently and specifically inhibits leukotriene B4 (LTB4) activity. Coversin is currently being clinically evaluated in four indications: bullous pemphigoid (BP), atopic keratoconjunctivitis (AKC), atypical hemolytic uremic syndrome (aHUS), and paroxysmal nocturnal hemoglobinuria (PNH). Akari believes that the dual action of Coversin on both C5 and LTB4 may be beneficial in AKC, BP, and aHUS. Akari is also developing other tick derived proteins, including longer acting versions.
