Evidence library

Primary sources for field context, plus a clear wall between wider CBD research and evidence generated with NWPT’s own formulation.

How to read this page: “Field” entries describe the broader literature. They are not claims about NWPT-SM32300. “Other product” rows concern formulations and populations that are not this programme. Product-specific rows stay free of efficacy claims until signed study reports exist.

Field — clinical high risk

doi:10.1001/archgenpsychiatry.2011.1472 · PubMed 22393215
Quantifies elevated transition risk in clinical high-risk samples relative to the general population; underpins why early-intervention research is scientifically motivated. Pooled rates vary by era, enrichment and setting; meta-analytic averages are not individual prognoses and are not NWPT programme results. Field

doi:10.1080/j.1440-1614.2005.01714.x · PubMed 16343296
Describes CAARMS and ultra-high-risk criteria used widely to operationalise clinical high-risk assessment in research. Instrument and criteria define research eligibility constructs — not a schizophrenia diagnosis and not evidence for any specific drug. Field

doi:10.1176/appi.ajp.2016.15070890 · PubMed 27363508
Shows how enrichment and individual risk profiles change expected event rates — relevant to trial design and sample-size thinking. Research prediction tool; external validity depends on population and predictors. Not a claim about NWPT-SM32300. Field

doi:10.1001/jamapsychiatry.2021.0830 · PubMed 34259821
Updated synthesis of cumulative transition probabilities over follow-up; reinforces that risk is elevated yet heterogeneous across studies. High between-study heterogeneity; cumulative risks are not destiny for any one person and do not establish treatment effects for this programme. Field

Other product — cannabidiol (not NWPT-SM32300)

CBD has been studied in psychosis and related conditions using other formulations. Those data inform hypotheses; they do not equal results for NWPT-SM32300, and they are not CHR-P prevention trials for this candidate.

doi:10.1176/appi.ajp.2017.17030325 · PubMed 29241357
Adjunctive CBD in established schizophrenia (other product / population context) — hypothesis-generating for cannabinoid research in psychosis more broadly. Not NWPT-SM32300. Not a CHR-P prevention study. Different population, product and clinical question. Other product
Epidiolex / Epidyolex regulatory labelling (epilepsy indications) Documents approved uses for a different CBD product in epilepsy — useful context for how another formulation has been regulated. Approved epilepsy indications are not CHR-P psychosis prevention and are not NWPT-SM32300 labelling. Other product

NWPT-SM32300 — programme-specific

Item Status Visitor note
Candidate description Described in company materials as NWPT-SM32300 (300 mg CBD micellar-emulsion softgel) Investigational product description only — not an approved medicine for CHR-P.
Comparative bioavailability vs Epidyolex Formal clinical study report not yet published here No numerical PK or safety figures on this site until a signed clinical study report is on file.
CHR-P efficacy / prevention of psychosis Not established Prevention of psychosis is the mission and research question — not a demonstrated result for this candidate.
Historical multi-site prevention plans (~328 participants) Planning precedent only; synopsis in development Earlier large-design figures are useful history — they are not a locked protocol for this programme.
