This is a phase 2 study to evaluate multiple doses of AK001 across 2 active doses. Pharmacodynamic activity will also be evaluated.

AK001 is a monoclonal antibody which may be useful in the treatment of patients with moderate to severe nasal polyposis

Study to Evaluate Multiple Doses in Patients With Nasal Polyposis

A Phase 2, Randomized, Double-blind, Placebo-controlled, Study to Evaluate Multiple Doses of AK001 in Patients With Moderate to Severe Nasal Polyposis

NPS was the sum of the right and left nostril scores, as evaluated by means of nasal endoscopy. Change in TPS from Baseline (prior to the first dose) to Week 12 (Day 84) was the primary outcome of the study. TPS ranges from 0 to 8 (scored 0 \[no polyp\] to 4 \[large polyps\] for each nostril), with a lower score indicating smaller-sized polyps, a higher scores mean a worse outcome.

If a patient completed the study with an ongoing adverse event (AE), investigational site personnel continued to follow-up until AE resolution and the documentation thereof. If, after 30 days from the study completion date, the AE was still continuing but not assessed as serious, the outcome was recorded as ongoing.

25 mg AK001 was administered as a single IV infusion through a peripheral vein on Days 0, 21, and 49.

After 40 of the 70 patients planned were randomized in the study, enrollment was stopped as the Sponsor decided not to pursue further development of AK001. The study was not stopped for any safety concern. Early termination resulted uninterpretable data.

Modified Intent-to-Treat (MITT) population included all randomized subjects who have taken at least one dose of the study drug and had both a baseline and at least one post-baseline efficacy assessment.
