What an IND submission means
An Investigational New Drug (IND) application is a regulatory submission to the U.S. Food and Drug Administration seeking to conduct clinical investigations of an investigational drug. It is not a marketing approval and does not establish that the product is safe or effective.
Before a proposed clinical study may proceed under an IND, the sponsor must provide information that may include nonclinical pharmacology and toxicology, manufacturing and quality information, and clinical study protocols. FDA may impose a clinical hold if it identifies concerns that must be resolved.
Clinical questions must be defined carefully
PTSD associated with veteran trauma, PTSD in people who also have opioid use disorder, and treatment outcomes for opioid use disorder are related but distinct research questions. They may require different eligibility criteria, study designs, safety monitoring and clinical endpoints. The initial IND scope and protocol are not yet published.
What is not yet established
- That kratom or any specific kratom alkaloid is an effective treatment for PTSD.
- That CBD is an established treatment for PTSD.
- The identity, composition, dose, route of administration or clinical formulation of the investigational product.
- The existence of a particular FDA-approved indication or marketing authorization.
Where we are today: we have not yet submitted an IND, received an IND effective date, or begun human trials.
Medical and regulatory notice: Nothing on this page is medical advice, a recommendation to use kratom or CBD, or an invitation to participate in a clinical trial. Do not stop or change prescribed treatment based on this information. For medical decisions, consult a qualified healthcare professional.
Scientific and regulatory context
FDA’s public information notes that no kratom or kratom-alkaloid drug product is FDA-approved and describes important safety and evidence gaps. NIH has separately reported an IND becoming effective for a purified mitragynine program aimed at opioid use disorder; that program is not evidence of PTSD efficacy and is not a CBDYNE program.
For background, see the FDA’s information on kratom (opens in a new tab) and the NIH news release archive (opens in a new tab). External links are provided for general context, not as endorsements or evidence of a relationship with CBDYNE.
