Self-Help Psychotherapy for Premenstrual Disorders

Regina, Saskatchewan
This study is testing a self-help mental health program that was designed to help people cope with the challenges of living with a premenstrual disorder. Individuals with a premenstrual disorder - either premenstrual dysphoric disorder or premenstrual exacerbation of depression - will track their daily symptoms for two menstrual cycles before they complete the program, throughout the two-cycle program, and for an additional two cycles after accessing the program. This will allow the research team to compare their symptoms before and after accessing the program.

Sertraline for Premenstrual Dysphoric Disorder

Baltimore, Maryland
Premenstrual dysphoric disorder (PMDD) is a severe affective disorder impacting millions of women worldwide, thought to be due to altered sensitivity to hormone fluctuations across the menstrual cycle. Neuroactive steroid hormones (NAS) and the gamma-aminobutyric acid (GABA)-A receptor (GABAAR) are thought to play a role in PMDD. This research will assess the blood levels of GABAergic NAS, expression of associated enzymes, and expression of GABAAR subunits across the premenstrual (luteal) phase of the menstrual cycle in healthy controls and individuals with PMDD. Within the PMDD group, the investigators will assess how these measures are affected by a low-dose antidepressant medication versus placebo. The results will provide a comprehensive view of the changes in these systems across the menstrual cycle and will add to the investigator's understanding of the mechanisms that underlie PMDD, as well as therapeutic mechanisms of PMDD treatment.

TMS for Depression

Philadelphia, Pennsylvania
The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic Resonance Imaging (MRI) procedures. Study participation will include completing various questionnaires, clinical assessments, receiving a full transcranial magnetic stimulation (TMS) treatment intervention (every weekday for 6 weeks), and undergoing MRI scans, both with and without concurrent TMS.

Adapted Cognitive-behavioral Therapy for Depression and Insomnia

Ottawa, Ontario
This study aims to better adapt cognitive behavioral therapy for insomnia (CBTi) for people with comorbid depression by using objective sleep measures to tailor the behavioral interventions components of CBTi. Using ambulatory monitors, we also aim to investigate changes in brain activity and heart rate throughout the intervention. In this parallel-group randomized clinical trial, participants undergo one week of baseline ambulatory monitoring after which they are randomly assigned to one of two intervention arms: 1) digitally delivered CBTi (eCBTi) based on standard subjective sleep measures (sleep diary), or 2) eCBTi based on objective sleep measures (EEG headband). The intervention spans over 5-weeks, followed by a week of ambulatory monitoring and follow-up measures one week and one month after the end of the intervention. The study also includes a post-intervention interview to gather feedback on participant experiences. The overall protocol includes online questionnaires and structured clinical interviews assessing sleep, insomnia, and mental health, as well as treatment-related measures before, during, and after the intervention. It is anticipated that eCBTi using objective sleep measures will lead to better treatment acceptability, satisfaction, and effectiveness, including greater improvements in symptoms of insomnia and depression. It is also anticipated that sleep EEG and heart rate profiles will improve along the course of eCBTi.

CBT + Antidepressants for Depression

Halifax, Nova Scotia
Depression currently affects close to 2 million Canadians and is the leading cause of disability worldwide. Pharmacological treatments (antidepressant medication) and psychological treatments such as cognitive-behavioural therapy are available for depression, but the majority of those who receive treatment have an unsatisfactory response. On average, the combination of pharmacological and psychological treatment achieves better results than either treatment alone. However, the apparently superior results of combination treatment may be due to the fact that different individuals preferentially respond to pharmacological or psychological treatment. The invesitagtors have discovered several clinical factors and biomarkers that predict poor response to commonly used antidepressant medication: history of childhood maltreatment, loss of interest and reduced activity, a biomarker of systemic inflammation, and a genetic marker of sensitivity to environment. Indirect evidence suggests that the same factors may indicate the need for psychological treatment, but their usefulness as differential predictors of psychological and pharmacological treatment outcomes remains to be established. The investigators will test the hypothesis that a pre-determined set of clinical variables (history of childhood maltreatment, loss of interest and reduced activity) and biomarkers (serum C-reactive protein, a marker of systemic inflammation, and short alleles of the serotonin transporter gene promoter polymorphism) differentially predicts response to antidepressants and to cognitive-behavioural psychotherapy with clinically significant accuracy. If this hypothesis is supported, the resulting predictor will allow personalized selection of treatment for depression, leading to improved outcomes and healthcare efficiency. Additional objectives include replication of additional predictors and integrative analyses aimed at refining the treatment choice algorithms.

Neurofeedback for Depression

Tulsa, Oklahoma
In this project, the investigators use real-time fMRI neurofeedback (rtfMRI-nf) to causally relate dysfunction of right anterior insula (rAI) and right superior temporal sulcus (rSTS) connectivity with the intensity of repetitive negative thinking (RNT). The investigators hypothesize that rtfMRI-nf reducing rAI-rSTS connectivity would reduce RNT. The investigators propose a randomized double-blind, sham-controlled trial of rtfMRI-nf with 110 young adults (n=55/arm) with major depressive disorder (MDD) and high trait-RNT levels.

Valganciclovir for Depression

Tulsa, Oklahoma
This study aims to determine whether treatment of CMV positive (CMV+) individuals with major depressive disorder (MDD) with valganciclovir (VGCV) alters neural circuitry, reduces inflammation, and improves depressive behavior and symptoms to a greater extent than placebo. In this double-blind, randomized placebo-controlled, parallel group trial, 24 individuals with a Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR) scale score ≥ 14 will be enrolled to participate in an 8-week treatment study. Participants will be randomized with a 1-1 ratio to receive 900 milligrams (mg) VGCV or placebo to be taken orally once per day. Participants will complete a 2-hour pre-screen, a baseline blood-draw, clinical evaluation, and MRI scan (visit 2), a clinical evaluation, blood draw, and MRI scan at week 4 (visit 6), and a clinical evaluation, blood draw, and MRI scan at week 8 (visit 10). Weekly telephonic visits to assess depressive symptoms and side effects will held between the in-person assessments.

LPS for Major Depressive Disorder

Tulsa, Oklahoma
This is a parallel group, double-blinded, placebo-controlled study. Participants with MDD (n=90) and HC (n=90) will be randomly assigned (2:1) to receive either lipopolysaccharide (LPS) (0.8ng/kg of body weight) or placebo (same volume of 0.9% saline) administered as an intravenous bolus. This will yield the following groups: MDD-LPS (n=60), MDD-Placebo (n=30), HC-LPS (n=60), HC-placebo (n=30). There are three main aims: to identify immune pathways and neural circuits that respond differently to LPS in MDD vs. HC subjects; (2) to test whether the strength of inflammatory changes induced by LPS is associated with degree of change in anhedonic symptoms and neural circuits in the MDD group, and (3) to identify a biotype of MDD that shows a differential immunological and neurophysiological response to LPS. The main outcome variables are symptoms of anhedonia measured with the Snaith-Hamilton Pleasure Scale (SHAPS), cytokines (Il-6, IL-8, IL-10, and TNF), and BOLD signal change in the neural circuitry mediating interoceptive processing, i.e. the insula and cingulate cortex. The exploratory aim is to determine whether the acute inflammatory response to LPS can predict the clinical course of depression over a period of six months. The main outcome of this component of the study is self-reported depressive symptoms assessed with the QIDS-SR.

Frequently Asked Questions

How much do Pmdd clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Pmdd clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Pmdd trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Pmdd is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Pmdd medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Pmdd clinical trials ?

Most recently, we added Collaborative Decision Skills Training for Serious Mental Illness, LIFUP Neuromodulation for Healthy Controls and Sertraline for Premenstrual Dysphoric Disorder to the Power online platform.

What do the "Power Preferred" and "SuperSite" badges mean?

We recognize research clinics with these awards when they are especially responsive to patients who apply through the Power online platform. SuperSite clinics are research sites recognized for a high standard of rapid and thorough follow-up with patient applicants. Meanwhile, Power Preferred clinics are the top 20 across the entire Power platform, recognized for their absolute top patient experience.

Which clinics have received Power Preferred and SuperSite awards recruiting for Pmdd trials ?

The Pmdd clinics currently recognized as Power Preferred are: Future Search Trials of Dallas in Dallas, Texas North Texas Clinical Trials in Fort Worth, Texas DM Clinical Research – Belliare in Houston, Texas The Pmdd clinics currently recognized as SuperSites are: Benchmark Research in Shreveport, Louisiana
