January 5, 2021 updated by: Allakos Inc.

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

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • TPS of ≥5 for both nostrils with presence on endoscopy of nasal polyps of grade ≥2 in each nostril according to the polyp grading scale
  • History of sinusitis symptoms
  • SNOT-22 ≥30
  • No clinically significant Screening 12-lead ECG, vital sign, hematology, chemistry, or urinalysis findings

Exclusion Criteria:

  • Use of systemic corticosteroids within 6 weeks of screening
  • Chronic use of antibiotic therapy within 3 months prior to Screening
  • Nasal surgery (including polypectomy) within 6 months prior to Screening
  • Use of investigational drugs or participation in another clinical trial within 30 days prior to Screening or 5 half-lives, whichever is longer

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Total Polys Score (TPS)
Time Frame: From Baseline (prior to the first dose) to Week 12 (Day 84)
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.
From Baseline (prior to the first dose) to Week 12 (Day 84)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
