Why Other Patients Applied

"I have struggled with depression since I was a child. I have experienced about more than 6 major depressive episodes lasting at least 4 months since I was 7 years old. I have tried talk therapy, a plethora of medication, and nothing has worked long term. Medication and talk therapy helps me manage and reduce the length of depressive episodes but I am in search for alternative treatments. My depression has made completing a bachelors degree a major challenge."

UD
Depression PatientAge: 25

"Dealt with treatment-resistant depression for pretty much my entire life. I would be eternally grateful for something that actually worked for once. I'd just like to feel normal. "

CM
Depression PatientAge: 55

"I had a serious spinal cord injury four years ago, and my entire life turned upside down. I lost everything including a 10 year relationship. I became handicapped and part of that handicap is a mental handicap or I just can’t seem to find my happiness anymore. I go to events where everybody’s laughing, smiling, dancing, and having a good time, and I seem to just sit there like a bump on log. It feels like my spirit is broken. I want to feel happiness and motivation for life again."

YX
Depression PatientAge: 76

"I have dealt with depression my entire adult life. I have been on multiple different meds, went through 10 weeks of TMS treatments (didn't work for me personally), done fairly extensive counseling. I’ve kind of lost hope that anything will ever help me to feel better. But I learned about new meds in clinical trials and I'm ready to try."

YP
Depression PatientAge: 60

"I've used SSRIs (Lexapro, Celexa) and they helped a bit but also, truthfully, they've had pretty serious sexual side effects. Depression was already hurting my marriage, and now these drugs continue to paralyze my it. I've heard that psilocybin-based treatments typically have no sexual side effects... I think a clinical trial will let me try safely."

DMT for Depression

West Haven, Connecticut
The goal of this phase 1 study is to investigate the safety and efficacy of dimethyltryptamine (DMT) in individuals with depression and healthy controls. We hypothesize that administration of DMT will result in decreases in depression, associated symptoms, and neuroplastic changes in depressed subjects. We expect that DMT will induce changes in neuroplasticity as indexed using electroencephalographic (EEG) measures and tasks in both depressed individuals and healthy volunteers, though to different degrees. These neuronal changes may in parallel cause changes in mood measured both in healthy and depressed subjects, which will be captured using appropriate psychometric measures of mood.

DepWatch for Depression

Farmington, Connecticut
The current best practice guidelines for treating depression call for close monitoring of patients, and periodically adjusting treatment as needed. This present study seeks to develop and investigate an innovative digital system, DepWatch, that leverages mobile health technologies and machine learning tools to provide clinicians objective, accurate, and timely assessment of depression symptoms to assist with their clinical decision making process. Specifically, DepWatch collects sensory data passively from smartphones and wristbands, without any user interaction, and uses simple user-friendly interfaces to collect ecological momentary assessments (EMA), medication adherence and safety related data from patients. The collected data will be fed to machine learning models to be developed in the project to provide weekly assessment of patient symptom levels and predict the trajectory of treatment response over time. The assessment and prediction results are then presented using a graphic interface to clinicians to help them make critical treatment decisions. The main question the present clinical trial aims to answer are as follows: 1. Feasibility of the digital tool, DepWatch, to assist clinicians in depression treatment and inform their clinical decision process 2. Effectiveness of the digital tool, DepWatch, to improve depression treatment outcomes All study participants will carry the DepWatch app on their smartphones and wear a Fitbit provided by the study team during the study period. They will also complete brief questionnaires via the app at specific time intervals throughout the study period.

This study is designed to examine SV2A density in MDD and PTSD as a correlate of synaptic density, and to determine whether ketamine administration will reverse the synaptic loss in vivo in human subjects. To our knowledge, this is the first human study to examine SV2A in vivo in MDD and PTSD and to use the first known drug (ketamine) that rapidly reverses synaptic loss to determine whether ketamine administration could restore some of the structural changes associated with depression and PTSD. After a screening process to determine eligibility, all subjects will participate in an MRI, and 2-3 PET scans with the administration of ketamine for one of the scans. Cognitive testing and a stress test may also be done on scan days.

Frequently Asked Questions

How much do Depression clinical trials in Connecticut 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 Depression clinical trials in Connecticut 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 Depression trials in Connecticut 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 in Connecticut for Depression 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 in Connecticut 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 Depression medical study in Connecticut?

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 Depression clinical trials in Connecticut?

Most recently, we added Counseling for Breast Cancer, CYB003 for Depression and SPT-300 for Depression to the Power online platform.

What are the current treatment options for depression?

Doctors use a stepped-care approach. First, most people try evidence-based talk therapy (such as CBT or interpersonal therapy), an antidepressant medicine (SSRIs are typical), or both, while also improving sleep, exercise and diet. If symptoms persist, the next “step” is to add or switch treatments—e.g., combining two medicines, adding lithium or an antipsychotic, or using brain-stimulation methods like transcranial magnetic stimulation or, for severe cases, electroconvulsive therapy; newer options such as esketamine nasal spray are reserved for treatment-resistant depression. Working with a clinician to review progress every few weeks and adjust the plan is key to finding the right mix.

When is depression considered severe?

Doctors call a depressive episode “severe” when almost all of the nine core symptoms are present at high intensity, the person’s daily life has largely shut down (can’t work, study, or manage self-care), or there are high-risk features like active suicidal thoughts, a recent attempt, or hallucinations/false beliefs. On common checklists this usually means a PHQ-9 score of 20 or higher, and it signals the need for urgent, comprehensive care—often a combination of medication, psychotherapy, and sometimes hospitalization. If you or someone you know reaches this point, treat it as an emergency and contact a mental-health professional or call/text 988 (USA) or your local crisis line right away.

Is it possible to never be depressed again?

Some people have a single episode of depression and stay well, but the risk of another episode is higher if you stop treatment too soon, have had several episodes before, or still have mild symptoms. You can greatly lower that risk by continuing the treatment that got you better for at least 6–12 months, learning relapse-prevention skills in CBT or mindfulness therapy, keeping regular sleep, exercise, and social routines, and checking in early with a professional if warning signs return. In short, there is no iron-clad guarantee you’ll never be depressed again, but staying on maintenance care and a healthy lifestyle makes long-term wellness much more likely.

What are the top 3 symptoms of depression?

Doctors look first for three core signs: 1) a low or hopeless mood that hangs around most of the day, nearly every day; 2) a marked loss of interest or pleasure in things you used to enjoy (called anhedonia); and 3) big changes in body energy—feeling drained, sleeping or eating far more or less than usual. If any of these have lasted two weeks or longer, it’s time to talk with a health professional, because other symptoms can pile on and treatment works best when started early.

Is depression a chemical imbalance?

No—depression can’t be pinned on one missing brain chemical. Research shows it arises from a mix of factors: how your brain circuits and several neurotransmitters work, your genes, long-term stress, and life circumstances all interact. Because causes differ from person to person, the most effective care is usually a combination of approaches—medication when needed, talking therapies, and lifestyle changes—worked out with your clinician.

How many people have untreatable depression?

Doctors call “untreatable” depression “treatment-resistant depression,” meaning the person has not improved after trying at least two suitable antidepressants. Large studies show this applies to roughly one-quarter to one-third of people with major depression—about 2–3 % of adults overall, or roughly 5–8 million U.S. adults in any given year. Importantly, many still respond to other options such as medication combinations, ketamine/esketamine, transcranial magnetic stimulation, or electroconvulsive therapy.

How to get out of deep depression?

Think of recovery as two tracks that run side-by-side. Track 1: get professional help right away—if you ever feel unsafe call 988 (or your local hotline), and with a clinician discuss proven treatments such as CBT, antidepressant medicine, and, when needed, newer options like ketamine, transcranial magnetic stimulation or electroconvulsive therapy. Track 2: reinforce the medical plan daily with mood-boosting basics—consistent exercise, regular sleep, balanced meals, limited alcohol or drugs, and time with supportive people—because these habits make the treatments work better and give you small, sustainable lifts while you heal.

Why is depression so hard to treat?

Depression is hard to treat because it isn’t a single disease—each person’s symptoms arise from a unique blend of brain chemistry, genetics, stress, medical issues, and life circumstances—so one-size-fits-all therapies rarely work. Without a blood test to guide choices, clinicians must try treatments sequentially, and roughly one-third of people need several steps or a combination of medication, talk therapy, lifestyle changes, or newer options like ketamine or magnetic stimulation before they feel well. The encouraging news is that persistence with a systematic plan and attention to sleep, exercise, and co-existing conditions allows most patients to eventually reach full recovery.

What are unhealthy coping mechanisms for depression?

Unhealthy coping means doing things that give quick relief but actually deepen depression—common examples include using alcohol or other drugs, overeating or not eating, oversleeping or endless screen-scrolling to avoid feelings, cutting or other self-harm, harsh self-talk and rumination, and withdrawing from friends or lashing out at them. These behaviors worsen mood, relationships, and safety; if you notice yourself relying on them, reach out to a trusted person or mental-health professional (or call your local crisis line) and ask about safer skills such as problem-solving steps, scheduled activity, or therapy.

Is it OK to have clinical depression?

Yes—having clinical depression isn’t a personal failing; it’s a common medical illness, and recognising it is the first step toward feeling better. What isn’t OK is to face it alone, because untreated depression can worsen and raise the risk of other problems, whereas most people improve with timely care such as talk therapy, medication, or a combination. If symptoms last more than two weeks or include thoughts of self-harm, book a visit with a primary-care doctor or mental-health professional and, in crisis, call 988 (U.S.) or your local emergency number—effective help and recovery are the norm when treatment is started.
