Study Endpoints

Primary Endpoints

Incidence of AEs
0-113 Days for SAD; 0-143 Days for MAD

The primary analysis will describe the incidence of AEs and laboratory abnormalities. AEs will be coded according to system organ class and preferred term using the Medical Dictionary for Regulatory Activities (MedDRA, version 28.0 or the current version). Their severity will be graded using the NCI CTCAE v5.0 or the current version.

Incidence of laboratory abnormalities
0-113 Days for SAD; 0-143 days for MAD

Clinical laboratory parameters (hematologic and blood chemistry) will be summarized by visit

Incidence of ECG abnormalities
0-113 Days for SAD; 0-143 Days for MAD

ECG findings (including QT abnormalities) will be summarized by visit.

Incidence of vital sign abnormalities
0-113 Days for SAD; 0-143 Days for MAD

Vital signs (systolic and diastolic blood pressure, temperature, heart rate) will be summarized by visit.

Frequently asked questions about ATTO-3712

What is ATTO-3712?

ATTO-3712 is an investigational small molecule being developed by Alamar Biosciences, Inc. for atopic dermatitis, also known as atopic eczema. It has been studied in a Phase 1 clinical trial that enrolled 48 participants, including healthy volunteers and patients with atopic dermatitis. It is not yet approved for any use.

What is ATTO-3712 used for in atopic dermatitis?

ATTO-3712 is being evaluated as a treatment for atopic dermatitis, a chronic inflammatory skin condition also called atopic eczema. The Phase 1 trial that studied it included patients with atopic dermatitis alongside healthy volunteers. Because the program is still in Phase 1, ATTO-3712 is investigational and has no approved indication.

Who is developing ATTO-3712?

ATTO-3712 is being developed by Alamar Biosciences, Inc., which trades under the ticker ALMR. The company is the sponsor of the Phase 1 trial evaluating the compound in healthy volunteers and patients with atopic dermatitis.

What phase is ATTO-3712 in?

ATTO-3712 is in Phase 1 clinical development. One Phase 1 trial has been completed, and no trials are currently active. The study was randomized, double-blind, and placebo-controlled, enrolling 48 participants. ATTO-3712 has not been approved by the FDA and remains an investigational drug.

What clinical trials is ATTO-3712 in?

ATTO-3712 has been studied in one Phase 1 trial, NCT07205081, titled Safety, Tolerability and PK of ATTO-3712 in Healthy Volunteers and Patients With Atopic Dermatitis. The trial is completed, enrolled 48 participants, and ran in the United States, Canada, and New Zealand. It included adults 18 years and older of all sexes.

How was the ATTO-3712 Phase 1 trial designed?

The ATTO-3712 Phase 1 trial, NCT07205081, was a randomized, double-blind, placebo-controlled study of safety, tolerability, and pharmacokinetics. It enrolled 48 participants, including healthy volunteers and patients with atopic dermatitis, across sites in the United States, Canada, and New Zealand. Participants were 18 years or older, and the trial is now completed.
