About this study

Official title: Safety and Efficacy of Dental Pulp Mesenchymal Cells in the Treatment of Depression:

This is a single center phase I / II clinical trial. Randomized, blind and positive drug parallel control were used to evaluate the safety and effectiveness of dental pulp mesenchymal cell injection in the treatment of depression 8 weeks after administration

Read the detailed description

This is a single center phase I / II clinical trial. Randomized, blind and positive drug parallel control were used to evaluate the safety and effectiveness of dental pulp mesenchymal cell injection in the treatment of depression 8 weeks after administration. The positive control drug was fluoxetine hydrochloride capsule with a dose of 40mg / day.The study included screening period (no more than 4 weeks), treatment period (8 weeks), and follow-up period (12 months).Subjects who met the inclusion criteria and did not meet the exclusion criteria were randomly assigned to the experimental group and the control group in the ratio of 1:1.During 8 weeks of treatment, subjects in the experimental group were given dental pulp mesenchymal cell injection + fluoxetine hydrochloride capsule simulant; The subjects in the control group were given dental pulp mesenchymal cell injection vehicle + fluoxetine hydrochloride capsule. During the treatment period, dental pulp mesenchymal cell injection / vehicle was injected intravenously for 4 times at an interval of 2 weeks (once at 0, 2, 4 and 6 weeks respectively); At the same time, fluoxetine hydrochloride capsule / simulant was taken orally every day during the treatment period.The efficacy and safety were evaluated 2 weeks after intravenous administration (visit and evaluation at 2, 4, 6 and 8 weeks respectively). Safety telephone follow-up was conducted 4 weeks (10th week), 6 months and 12 months after the last intravenous administration.

Questions about this trial

What is this clinical trial studying?

A study testing Dental pulp mesenchymal cell injection and fluoxetine hydrochloride capsule in people with Depression, run by CAR-T (Shanghai) Biotechnology Co., Ltd..

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 7 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 19 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Results are not available in the source record.

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

Contact Yong You, Doctor (0898-66809233, 652797262@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The total score of Montgomery Asperger Depression Scale (MADRS) decreased from baseline after 8 weeks of treatment (time frame: 8 weeks). 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 19 Nov 2021.
