Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 2 randomized, double-blinded, placebo-controlled study that will evaluate multiple potential pharmacotherapeutic interventions for Post Traumatic Stress Disorder (PTSD) utilizing an adaptive platform trial (APT) design.

Intervention D - SLS-002 will assess the safety and efficacy of SLS-002 in participants with PTSD.

Please see NCT05422612 for information on the S-21-02 Master Protocol.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The general structure of this Adaptive Platform Trial (APT) consists of a 30-day Screening Period, a 12-week Platform Treatment Period, and a 4-week Safety Follow-up. The S-21-02 Platform Trial will evaluate the safety and efficacy of multiple investigational products for the treatment of PTSD (see NCT05422612 for Master Protocol information). Participants are randomized among the multiple cohorts in the study and the resulting randomization enables sharing/pooling of control subjects, where all interventions may be compared to a common control (placebo). This record only includes information relevant to the SLS-002 cohort.

Once a participant meets all eligibility criteria for the Master Protocol, eligibility for each currently enrolling intervention cohort is assessed. Eligible participants will be randomized with equal probability into a cohort. Participants randomized to the SLS-002 cohort are then randomly assigned to receive either SLS-002 or placebo (in a ratio of 5:3; intervention:placebo), for the duration of the 12-week treatment period.

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
The overall 2-stage randomization scheme will be implemented by an unblinded statistician who is otherwise uninvolved in study operations. Participants will be assigned a study number at Screening (Subject ID). In the first stage of randomization, eligible participants who complete screening will be randomly assigned to an open platform cohort for which they are eligible (both site PIs and participants are aware of the cohort assignment) and, within that cohort, the second stage of randomization is to intervention vs placebo (double-blind) using Interactive Response Technology (IRT).

For this Adaptive Platform Trial (APT), participants assignment to a cohort will not be blinded. The devices used in this cohort may not be visually similar between cohorts and blinding to cohort assignment is not necessary to avoid bias. However, within each cohort, participants, site personnel, contract research personnel and the sponsor will be blind to treatment assignment (intervention vs. placebo).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Is able to complete intranasal administration of study intervention.
2. Is able to refrain from alcohol or cannabis consumption/use on dosing days.
3. Is willing and able to attend dosing visits as outlined in the protocol (twice a week for the first 8 week and then once a week for Weeks 9 through 12) and agrees not to drive a car or operate machinery for 24 hours after receiving the study intervention.

Exclusion Criteria

1. Has a history of seizures (other than childhood febrile seizures).
2. Has a body mass index \>40 or \<18 kg/m2 at Screening.
3. Has known, uncontrolled hypertension or blood pressure that, in the investigator's judgment, should exclude the subject at Screening or Baseline (blood pressure may be repeated as per the site's standard operating procedures).
4. Has a known history or current finding of cardiovascular disease, cerebrovascular disease, advanced arteriosclerosis, structural cardiac abnormality, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, congenital heart disease, ischemic heart disease, cardiac insufficiency, supraventricular, ventricular heart rhythm disorder, prolonged QT syndrome (ie, QTcF \>450 msec for males and \>470 msec for females) or associated risk factors (ie, hypokalemia, family history of long QT syndrome), syncope, cardiac conduction problems (eg, clinically significant heart block), exercise-related cardiac events including syncope and pre-syncope, clinically significant bradycardia, or other serious cardiac problems.
5. Has a concurrent chronic or acute illness, or other condition (eg, narcolepsy, uncontrolled hyper- or hypothyroidism) that might confound the results of safety assessments conducted in the study.
6. Has any medical condition that could interfere with the absorption of intranasal ketamine (eg, nasal polyps, clinically significant deviated septum \[corrected or persistent\], or other physical abnormalities of the nose).
7. Has a history of interstitial or ulcerative cystitis, overactive bladder, painful bladder
8. syndrome, chronic pelvic pain, frequent recurrent urinary tract infections, autoimmune disease, active urinary tract infection, history of prostate cancer, bladder cancer or bladder

a. surgery, or symptoms suggestive of these disorders (eg, high urinary frequency, persistent urge to urinate).
9. Has any history of using ketamine or esketamine. Note previous use of ketamine for anesthesia is allowed.
10. Has known or suspected intolerance or hypersensitivity to the study intervention(s), closely related compounds, or any ingredients.

Does not meet or is not willing to comply with the requirements listed in protocol related to prohibited and restricted medications and therapies, as well as required washout periods prior to participation. Prohibited medications and therapies include, but are not limited to, monoamine oxidase inhibitors (MAOIs), chronic/frequent use of opioids or drugs with activity at the opioid receptor, psychostimulants, mood stabilizers/anticonvulsants, antipsychotics, or any medication/therapy that might confound the results of safety assessments conducted in the study. Subjects who have received any of these prohibited medications within 30 days of Screening are excluded from the study. Potent CYP 3A4 inhibitors, including nefazodone and fluvoxamine, are not permitted within 1 week of first dose and until at least 1 day after the last dose. Potent CYP 3A4 inducers, including a. St. John's wort, are not permitted within 30 days of first dose and until at least 1 day after the last dose.
