2 Developing the next generation of rare & orphan anti - inflammatory therapies Akari Mission Statement Ticks have undergone 300 million years of natural selection to produce inhibitors that bind to key inflammatory mediators and are well tolerated in humans . Our unique molecules are derived from these inhibitors
3 Exploiting Evolutionary Benefits of Tick - Derived Proteins Tick salivary proteins work by inhibiting host immune responses, enabling tick to repeatedly feed without damage from host inflammatory response EFFICIENT TARGETED Target early inflammatory mediators Specific binding avoids off - target effects
4 Akari Highlights * PNH: Paroxysmal nocturnal hemoglobinuria; aHUS: Atypical hemolytic - uremic syndrome; AKC: Atopic keratoconjunctivitis; BP: Bullous Pemphigoid Developing tick - derived proteins to inhibit early inflammation Three separate development programs, each focused on distinct inflammatory pathways 1) Complement program • PNH* - projected Phase III start – 4Q 2017 • aHUS * - projected Phase II start – 4Q 2017 • Once - weekly dosing molecule in development 2) Dual C5 & leukotriene B4 (LTB4) program • AKC * & BP * - projected Phase II starts – 1Q 2018 3) Scientific development program • Other tick - derived and engineered molecules
5 Strategic Positioning Active PNH & upcoming aHUS trials Growing list of other targets Potential for 20 - 30% market share Potential to achieve dominant market share as sole provider Complement inhibition Expected to be ~$5 billion peak market Sub Q delivery differentiated against current IV standard of care Leukotriene + Complement inhibition Developing orphan market Differentiated Mechanism of Action Active AKC, BP, Systemic programs and other targets with high degree of unmet need

14 Planned PNH Phase III Trials CAPSTONE and ASSET • Two PNH Phase III clinical trials: ‒ Naïve patients (CAPSTONE) ‒ Switch (ASSET) • CAPSTONE: Naïve patients randomized to Coversin plus standard of care vs. standard of care • ASSET: Eculizumab - treated patients randomized to remain on eculizumab or switch to Coversin • In discussion with regulators regarding trial designs • CAPSTONE currently projected to commence 4Q 2017
15 Coversin Targeting Atypical Hemolytic Uremic Syndrome (aHUS) • Chronic and life - threatening genetic disease characterized by microangio - pathic hemolytic anemia, thrombocytopenia, and kidney injury • Efficacy of C5 inhibition in aHUS demonstrated by the approval of eculizumab for this indication • aHUS physicians have expressed support for once - daily Coversin – More therapeutic flexibility for episodic patients – Patient convenience • Phase II trial – up to 10 naïve patients at six sites across Europe, projected to begin in 4Q 2017

17 Dual Leukotriene and Complement Inhibition by Coversin Has Potential In Wide Range of Diseases with Unmet Need Complement Only Leukotrine & Complement Asthma Rheumatoid Arthritis PAH Trauma Sjögren’s Bronchiolitis obliterans COPD AATD Bullous Pemphigoid Goodpasture’s AKC Dry Eye PNH aHUS Mucous Membrane Pemphigoid MG NMO
18 Two Phase II Leukotriene/Complement Trials Projected to Start in 1Q 2018 • Phase II programs ‒ AKC (atopic keratoconjunctivitis) - eye (topical drops) ‒ BP (bullous pemphigoid) – skin (sub Q) • Several severe lung conditions are impacted by complement and leukotriene pathways with zileuton and montelukast both prescribed • Dual activity creates potential for unique treatment option Neutrophil recruitment to mouse lung induced by LPS in presence of Coversin or Zileuton Data from Pneumolabs 2017 Dual action (Coversin) more effective than C5 - only (saturated Coversin) or Zileuton alone in mouse model
Coversin & L - Coversin Potentially Superior Strategy to Target LTB4 Previous strategies to target LTB4 suffered from a lack of selectivity; benefits of reducing LTB4 were offset by off - target effects Coversin and L - Coversin capture LTB4 within an internal binding site • Directly and specifically “mop up” LTB4 without perturbing other pathways • Unique LTB4 targeting selectivity ‒ Expected not to reduce anti - inflammatory lipoxins ‒ Does not inhibit PGP (an anti - inflammatory agent) degradation Roversi, P. et al., J Biol.

Collaboration with Moorfields Hospital (Institute of Ophthalmology) EIC pre - clinical model of severe eye surface inflammation Demonstrated Benefit in Mouse Model Late - Phase Ocular Inflammation • C57/Bl6 mice sensitized to OVA for 14 days • OVA eye surface challenge for 6 days post sensitization (days 0 – 6) • Coversin applied once daily on days 3 – 6 after inflammatory response well established • Maximum effect seen after 3 days of Coversin treatment (late phase of inflammation) • Coversin - 64% reduction in inflammatory score compared to placebo in mouse model • Timing indicative of T cell response • Historical comparison*: ‒ Cyclosporin A (0.1%) - 43% reduction ‒ Betamethasone (0.1%) - no significant reduction 0 1 2 3 4 5 6 7 8 Day 3 Day 4 Day 5 Day 6 Inflammation score Effect of Coversin on OVA induced inflammation (n=16 per group) Placebo Coversin p<0.0001 p<0.01 * Shii D, Nakagawa S, Yoshimi M et al. 2010; Biol Pharm Bull 33(8):1314 – 1318 22
Atopic Keratoconjunctivitis (AKC) • Severe eye surface inflammation causing infiltration of immune cells such as neutrophils and T cells. A cause of blindness worldwide • Topical drugs, such as steroids or cyclosporin , often not effective or cannot be given chronically • In AKC disease, despite best current treatment many patients progress to severe corneal involvement • Both complement and LTB4 known to be involved • Progresses to affect the cornea and may lead to loss of vision. Both eyes affected 23 • Therapeutic success in this indication could open up other cicatrising eye surface conditions • Phase I/II randomized, double masked, placebo - controlled trial at Moorfields Eye Hospital and Royal Liverpool Hospital projected to start 1Q 2018
Coversin Demonstrated Benefit in Bullous Pemphigoid Model Preclinical passive mouse model from Dr. Sadik in Lubeck, Germany Leading Bullous Pemphigoid center P=0.0023 between vehicle and 250 µg/kg • ~60% reduction in affected area on Coversin (Sub Q) compared to vehicle or steroid in mouse model • Clear dose response Vehicle 250µg/kg Coversin 24
25 Bullous Pemphigoid (BP) Significant Unmet Need • Immune complex deposition initiates complement cascade and inflammatory process • LTB4 recruits neutrophils to dermis - epidermis junction and amplifies inflammation • Phase II open label trial against standard of care projected to start in 1Q 2018 in three centers in Europe
