Early Phase 1

Recruiting

Conditions: Narcissism

Interventions: Drug: midomafetamine (MDMA)-Assisted Therapy

Registration Number: NCT06565494

Lead Sponsor: University of Washington

Brief Summary: This open-label, proof-of-concept pilot study will assess the efficacy and safety of midomafetamine (MDMA) - assisted therapy (AT) for participants diagnosed with pathological narcissism. As all participants will be allocated to a single group assignment, there will be no blinding, randomization, or comparator treatment. Participants will have a screening visit, a preparation period of 3 visits, a treatment period receiving MDMA-AT at 3 monthly visits, a 6 month follow up period coming in at one week, one month, three months and six months after last treatment visit.

Detailed Description: This open-label, proof-of-concept pilot study will assess the efficacy and safety of midomafetamine- assisted therapy (MDMA-AT) for participants diagnosed with pathological narcissism. As all participants will be allocated to a single group assignment, there will be no blinding, randomization, or comparator treatment.

Up to 12 participants will be enrolled. Each participant will have 2 informants, one family member and one psychotherapist.

The visit schedule for each participant will be comprised of the following:

* Screening Period: phone screen, visit screen, informed consent, eligibility assessment, and enrollment invitation to eligible participants;

* Preparation Period: medication tapering, three Preparation Sessions, Baseline assessments, Enrollment Confirmation;

* Treatment Period: three monthly Experimental Sessions and nine associated Integration Sessions over \~12 weeks;

* Follow-up Period and Study Termination: four Follow-up Visits at one week, one month, three months and six months after the final Integration Session to collect clinical outcome measures; Study Termination will happen at the last Follow-up Visit.

The treatment (MDMA-AT) consists 3 Preparation sessions followed by 3 Experimental sessions at 4-week intervals; after each Experimental session, 3 weekly Integration sessions will be conducted. For the first Experimental Session, the dose of MDMA is 80 mg; for the second and third Experimental Sessions, the dose of MDMA is 120 mg. For all three Experimental sessions, a supplemental dose of 50% of the initial dose will be available. The Preparation, Experimental, and Integration Sessions will involve psychotherapy developed specifically for this trial and population.

Are able to give adequate informed consent.
Are able to swallow pills.
Must agree to safety lab assessments including a complete blood count and a metabolic panel inclusive of kidney and liver function tests.
Must agree to a screening 12-lead ECG that is evaluated by a qualified cardiologist to rule out any baseline cardiac abnormalities which would lead to enrollment exclusion; if a 12-lead ECG has been obtained in the last 12 months that has been evaluated by a qualified cardiologist, this may be used for screening purposes in which case participants must sign a medical release in order for study investigators to obtain a copy for review.
Must agree to a 1-minute rhythm strip at the Screening Visit to assess for heretofore undiagnosed arrhythmias.
Must agree to commit to the midomafetamine (MDMA) dosing, Experimental Sessions, non-drug Preparation and Integration Sessions, Follow-up Visits to complete clinical measures at all four Follow-up endpoints, and all necessary telephone contact.
Must select a family member (spouse/partner or relative) with whom they are willing to allow Study Staff to communicate and whom they consent to complete Informant-report assessments at Baseline (T0) and at all Follow-up endpoints (T1-T4). Contact information (cell phone & email address) for their selected family member must be provided by participant at the Screening Visit. Participant's selected family member must consent to participate and provide written informed consent.
Must be willing to sign a medical release for Study Staff to communicate directly with the participant's psychotherapist and consent to their completing Informant-report assessments at Baseline (T0) and at all Follow-up intervals (T1-T4).

Are willing to comply with all medication requirements per protocol.
Must be willing to taper off all prohibited medications and substances with drug-drug interactions with MDMA for at least five half-lives of the drug plus one week for stabilization to ensure an appropriate medication washout to avoid the possibility of interactions prior to the third Preparation Session. Must also agree not to resume any prohibited non-psychoactive medications until 40 hours (five half-lives of MDMA) after the last Experimental Session. Must agree to sign a medical release for Study Staff to communicate with the participant's prescribing physician who will direct medication tapers.
Must be willing to taper off all prohibited psychoactive medications (including SSRIs, SNRIs, MAOIs, other antidepressants) as well as other psychoactive medications (including mood stabilizers and anti-psychotics) and psychoactive substances to ensure an appropriate washout prior to the third Preparation Session when Baseline outcome measures are obtained. Must also agree not to resume any of these medications until all primary outcome data is collected at the time of Study Termination unless restarting is required/or in the best interest of the participant. Must agree to sign a medical release for Study Staff to communicate with the participant's prescribing physician who will direct medication tapers.
Must be willing to work with their outside prescribing physician(s) who will direct and oversee the tapering of all prohibited medications.
Are able to decrease dose of allowable opiates, if used for pain management, leading up to the Experimental Session in order to avoid taking the medication prior to the initial MDMA administration and 24 hours after. During this period, the participant will be allowed to take the medication if needed for intolerable pain flare-ups or to prevent withdrawal symptoms.
Agree to attending all the study sessions, and agree not to be enrolled on another interventional clinical trial without approval of the study investigators for the duration of this study.
Are willing to attend Experimental and Integration Sessions without a support-person present; while some previous trials have permitted support persons to be present for portions of the Treatment Period, the presence of a family member may inhibit patients with pathological narcissism who struggle with shame and fear of exposure.

(Prior to invitation to the Screening Visit, all participants will have been pre-screened with questions from the Personality Diagnostic Questionnaire - Version 4+ (PDQ-4+) to assess for the DSM-IV/5 Section II diagnostic criteria for NPD and the Super Brief Pathological Narcissism Inventory (SB-PNI) to assess for narcissistic grandiosity and narcissistic vulnerability consistent with pathological narcissism.)
Must be in an ongoing (greater than 6 months) outpatient individual psychotherapy with a clinically licensed psychotherapist who agrees the participant's primary diagnosis is pathological narcissism. Need to be known to their psychotherapist for at least six months or to the study team as a patient of Dr. Albert for at least six months.
Must agree to continue their ongoing psychotherapy with their psychotherapist through the 12-week Treatment Period.

Medical Conditions
May have well-controlled hypertension that has been successfully treated with anti-hypertensive medicines.
May have asymptomatic Hepatitis C virus (HCV) that has previously undergone evaluation and treatment as needed.
May have a history of or current Diabetes Mellitus if screening rules out cardiovascular disease that would meet an exclusion criterion and the condition is judged to be stable on effective management.
May have hypothyroidism if taking adequate and stable thyroid replacement medication.
May have a history of or current glaucoma if approval for study participation is received from an ophthalmologist.
If there are any questions about possible medical problems, the study physician will request additional tests, assessments, or measures as indicated. The study physician may also contact outside providers with participant permission as needed.
Additional visits (in person, by telephone, or via telemedicine) may be scheduled at the discretion of the study investigators to collect more information for determining eligibility or to discuss study expectations with the potential participant.

Exclusion Criteria

Are not able to give adequate informed consent.
Are less than 18 years old or 65 years or older.
Have any current problem which in the opinion of the study investigators, study physician or Medical Monitor might interfere with participation including:

Have had active suicidal ideation and/or behaviors in Past 12 Months as assessed with the MINI at the Screening Visit. For those assessed to be at Moderate Risk or High Risk "likely in the near future" using the established MINI thresholds, participants' personal therapists will be contacted to assist in triage planning. If it is determined that the participant is at imminent risk of suicide and/or the personal therapist is unavailable, emergency services will be called for transfer to the nearest Emergency Department and "a "warm hand-off" will be made to a receiving provider there.
Have a current alcohol or substance use disorder as assessed with the MINI at the Screening Visit.
Have a co-occurring dissociative identity disorder diagnosis from their current clinically licensed psychotherapist.
Have used MDMA within the last 12 months.

Medical Conditions

Have a history of ventricular arrhythmia at any time, other than occasional premature ventricular contractions (PVCs) in the absence of ischemic heart disease. Have a history of atrial flutter or any arrhythmia at any time, other than occasional PVCs in the absence of ischemic heart disease. Participants with a history of paroxysmal supraventricular tachycardia, paroxysmal atrial tachycardia, or atrial fibrillation arrhythmia may be enrolled if successfully treated with ablation cardioversion treatment at least 12 months prior and cleared by a cardiologist, the site physician, and Medical Monitor.
Have Wolff-Parkinson-White syndrome or any other accessory pathway that has not been successfully eliminated by ablation.
Have a marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 milliseconds corrected by Bazett's formula).
Have a history of additional risk factors for Torsade de pointes (e.g., heart failure, hypokalemia, family history of Long QT Syndrome).

Participants with other mild, stable chronic medical problems may be enrolled if the study investigators, study physician, and Medical Monitor agree the condition would not significantly increase the risk of MDMA administration or be likely to produce significant symptoms during the study that could interfere with study participation or be confused with side effects of the IMP.
Have symptomatic liver disease with liver function tests (AST/ALT/ALP) 1.5x greater than the upper limits of normal.
Have history of hyponatremia or hyperthermia.
Weigh less than 48 kilograms (kg).
Are pregnant or lactating or nursing, or are of childbearing potential and are not practicing an adequate birth control method.
