Alexza Pharmaceuticals publishes results, AZ-009, (rapid-acting inhaled apomorphine)

Alexza Pharmaceuticals publishes results from a randomized clinical trial assessing the safety, pharmacokinetics, & efficacy during morning OFF of their agent AZ-009 (rapid-acting inhaled apomorphine) being developed for #Parkinsons

Results

AZ-009 was rapidly absorbed with peak plasma concentrations at 2 minutes, as compared to 30 minutes for subcutaneous apomorphine. Adverse events for AZ-009 were comparable to subcutaneous apomorphine, except for mild and transient throat irritation. Adverse events limited AZ-009 dose escalation in HVs to 3 mg. Patients tolerated up to 4 mg. In patients with PD, 2, 3, and 4 mg AZ-009 reduced mean Movement Disorder Society-Unified Parkinson's Disease Rating Scale part III score (standard deviation) by 10.7 (13.6), 12.8 (7.9), and 10.3 (3.7) points, respectively, compared to 4.8 (4.9) after placebo at 10 minutes postdose. The percentage of patients achieving full on within 45 minutes postdose increased dose dependently: 0% (placebo), 17% (2 mg), 50% (3 mg), and 83% (4 mg).

Conclusions

AZ-009 appears to be a rapid-acting and reasonably well-tolerated formulation for treating off periods. © 2022 The Authors. Movement Disorders published by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society
