New formulation of intravenous vinorelbine tartrate designed to reduce vein irritation ANX-530 (vinorelbine emulsion) Patient enrollment complete in a marketing-enabling 28-patient bioequivalency study of ANX-530 and Navelbine under 505(b)(2) Preclinical studies have demonstrated: Reduced vein irritation, redness and swelling Pharmacokinetics and antitumor activity similar to Navelbine ANX-530 (vinorelbine emulsion ) Navelbine? (vinorelbine) Indicated as single agent or in combination with cisplatin for first-line treatment of unresectable advanced NSCLC Injection site reactions in approximately one-third of patients Annual global market > $200M

Vein Irritation Edema Erythema ANX-530 Preclinical Results Lower Vein Irritation, Erythema & Edema 2nd Injection: Navelbine? (vinorelbine) ANX-530 Navelbine: Due to the severity of toxicity, animals did not receive the full set of injections but were still analyzed for toxicity after each injection period. High dose group received 1st injection only. Increasing toxicity 1st Injection: multiple of human dose multiple of human dose multiple of human dose Navelbine ANX-530 2x 4x 8x 2x 4x 8x 2x 4x 8x 2x 4x 8x 2x 4x 8x 2x 4x 8x Increasing toxicity

ANX-530 Preclinical Results Ear Vein Histopathology ANX-530 exhibited markedly less ear vein histopathological toxicity in preclinical studies Following intravenous treatment in rabbits, ear vein tissue sections were scored for severity of symptoms (0 to 3 scale = no observable event to marked severity). Toxicity score represents the summation of scores from seven separate vein sections/rabbit.
