Australia87 participantsStarted 2025-10-01
Plain-language summary
This study is assessing the efficacy and safety of NPX-5 in psilocybin-assisted psychotherapy for the treatment of adjustment disorder due to cancer diagnosis.
Who is it for? This study is for people who are aged between 18 and 80 years old and suffer from anxiety after adjusting to an acutely stressful event of their cancer diagnosis. This is called adjustment disorder.
Study details Participants in this study will be randomly allocated by chance (similar to flipping a coin) to one of three groups: a 25mg NPX-5 dose group, a 10 mg NPX-5 dose group or a 1mg NPX-5 dose group. Participants will be allocated a dose that will be administered during their psilocybin-assisted psychotherapy (PAP) dosing session. The PAP dosing session will run approximately 8 hours, with NPX-5 administered at Day 14 (dosing day).
At Week 10, non-responders that continue to meet the study eligibility criteria may commence an additional PAP cycle (at 25 mg NPX-5). A maximum of 2 PAP cycles may be administered. Long term follow up will comprise of a study visit at 3 months post Week 10 (of the final cycle) to assess safety and tolerability of NPX-5.
It is hoped that this research will develop important scientific knowledge that could contribute to the development of a potential new treatment for anxiety and depression after adjusting to an acutely stressful event such as a cancer diagnosis.

What they're measuring
1
Anxiety Severity
Timeframe: Comparison between treatment groups in the change from baseline in the Hamilton Anxiety Rating Scale (HAM-A) total score at Week 10 after a single PAP cycle.
2
Number of participants with treatment-related adverse events as assessed by CTCAE V5.0
Timeframe: Assessment of Day 14 (dosing day) vital signs (pre-dose and prior to discharge).
3
Safety and Tolerability of a Single Dose of NPX-5 using the Sheehan Suicide Tracking Scale (S-STS)
Timeframe: Assessment of suicidality using the Sheehan Suicide Tracking Scale (S-STS) at baseline, Day 13, Day 15, Weeks 4, 6, and 10, and 3 months post-final cycle.
✕0. Agree not to take any sedating medications for a minimum of 12 hours before the dosing session including benzodiazepines, zopiclone, eszopiclone, zaleplon and zolpidem. Medications for cancer-related pain are permitted.
✕1. Must be willing and able to refrain from smoking throughout the duration of the dosing session. Nicotine replacement therapies may be permitted with the agreement of the medical monitor.
✕2. Agree that for 1 week before the psilocybin dosing session, participants will refrain from taking any illegal drugs or non-prescription medication (including cannabis, or CBD or THC containing products), nutritional supplement, or herbal supplement except when approved by the study investigators. Additionally, agree not to take any form of psilocybin outside of the study, including microdosing, from baseline through Day 70/Week 10 (Visit 11).
