About this study

Official title: A Phase I/II Randomized, Open-Labeled Study to Evaluate Pharmacokinetic and Pharmacodynamic Effects and Safety of ALZT-OP1 in Subjects With Alzheimer's Disease and Normal Healthy Volunteers

This is a randomized, open-label, cross-over, pharmacokinetic and pharmacodynamic PK/PD study. (Part A)The PK portion of the study is designed to evaluate the pharmacokinetics of ALZT-OP1 (a combination drug therapy) designated as ALZT-OP1a and ALZT-OP1b, in both plasma and CSF, following co-administration of the two active investigational products, in healthy volunteers and Alzheimer subjects aged 55-79 and in good health. (Part B) The PD portion of the study will evaluate the pharmacodynamics of ALZT- OP1, using both plasma and CSF biomarkers, following 60 days of consecutive daily treatment, in AD subjects only.

Read the detailed description

This is a phase I/II randomized, open-label, cross-over, PK/PD study. The PK (Part A) portion of the study is designed to evaluate both single and double doses of ALZT-OP-1a (17.1mg or 34.2 mg) and ALZT-OP1b (10 mg or 20 mg) in both Alzheimer's subjects and healthy volunteers. The PD (Part B) portion of the study is designed to evaluate single doses of ALZT-OP-1a (17.1mg) and ALZT-OP1b (10 mg) in AD subjects treated for 60 days. An Alzheimer's control group will be utilized for comparison to active treatment groups but will not be administered study treatment; however, they will have biomarkers collected.

PK (Part A) n=24, both healthy volunteers and AD subjects

Part A is an open-label study, cross-over, PK study where 24 subjects will be randomly assigned to receive treatment regimen A-B or B-A for two consecutive day of dosing.

Subjects will be admitted to the Phase 1 unit the morning before dosing and will initiate dosing the following morning for 2 consecutive days of dosing (A-B, or B-A).

Day 1 (A-B) will consist of a single inhaled oral dose of ALZT-OP1a via dry powder inhaler + a single oral tablet dose of ALZT-OP1b.

Day 2 (B-A) will consist of two oral inhaled doses of ALZT-OP1a, not more than 2 mins apart, via dry powder inhaler + two oral tablets doses of ALZT-OP1b.

Day 1 (B-A) will consist of two oral inhaled doses of ALZT-OP1a, not more than 2 mins apart, via dry powder inhaler + two oral tablets doses of ALZT-OP1b.

Day 2 (A-B) regimen consists of a single inhaled oral dose of ALZT-OP1a via dry powder inhaler + a single oral tablet dose of ALZT-OP1b.

AD subjects will be given the option to roll over into the PD portion of the study.

PD (Part B) n=32, AD subjects only

Part B is an open-label, PD study where 32 AD subjects will be randomly assigned to receive either active treatment or be assigned to a non-treatment control arm.

Twenty-four (24) subjects will be randomly assigned to Treatment Group 1 to receive a single (17.1 mg) inhaled dose of ALZT-OP1a plus a single (10 mg) oral dose of ALZT-OP1b daily for 60 days.

Eight (8) subjects will be randomly assigned to Treatment Group 2 (Control Group) and will not be administered study drug.

All subjects will have plasma collected on Day 1, Day 30, and Day 60 and CSF collected on Day 1 and Day 60.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALZT-OP1 (cromolyn and ibuprofen) ALZT-OP1a (cromolyn) and ALZT-OP1b (ibuprofen) in people with Healthy Volunteers and Alzheimer Disease, run by AZTherapies, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part A Non-compartmental PK parameters will be calculated and reported for ALZT-OP1a and ALZT-OP1b (time frame: • 2 Days). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2022.
