Life's End Benefits of cannaBidiol and tetrahYdrocannabinol

Phase 2

Recruiting

• Conditions: Agitation; Dementia
• Interventions: Drug: Placebo

• Registration Number: NCT05644262
• Lead Sponsor: University of Southern California

Brief Summary

This is a multicenter randomized double-blind placebo-controlled Phase 2 study of an oral combination of tetrahydrocannabinol (THC) and cannabidiol (CBD) compared to placebo over 12 weeks. This study is designed to test the hypothesis that treatment with an oral combination of THC/CBD will reduce agitation hospice care-eligible patients with agitation and dementia as measured by the Cohen Mansfield Agitation Inventory (CMAI) when compared to placebo at 2 weeks.

This study will enroll approximately 150 participants of any gender at least 40 years of age who are hospice care-eligible with agitation and dementia (HAD). Participants will be randomized (50:50) to either active study drug (T2:C100) or placebo.

The double-blind period of this study is 12 weeks. A 12 week optional open-label extension will be offered to participants who complete the double-blind period.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 150

Inclusion Criteria

1. Provision of signed and dated informed consent from participant or legally authorized representative.

2. Person of any sex/gender 40 years of age or older.

3. Ability to take or be administered liquid medication.

4. Meets DSM-V criteria for Major Neurocognitive Disorder.

5. Current clinically significant agitation as demonstrated by an NPI-agitation subscale of 4 or above at Screening.

6. Meets at least one of the following requirements:

   1. Currently enrolled in out-patient or in-patient hospice care.
   2. Stage 6d on the Functional Assessment Staging Test (FAST).
   3. Score of 12 or more according to the Advanced Dementia Prognostic Tool (ADEPT) as implemented by the Mitchell Index.

7. Willing to agree not to use cannabinoids in any form (e.g., topically applied, ingested, inhaled, or other form of administration), other than the trial medication, during the first 12 weeks of the study.

8. Has a third-party clinician (e.g., hospice, palliative care, PCP) who is responsible for medical management of the participant outside the study.

9. In the opinion of the investigator, resides in an environment suitable to conduct a clinical trial (i.e., study intervention can be administered and concomitant medication use can be accurately documented).

10. In the opinion of the site PI, has a study partner (may be paid or unpaid caregiver) able and willing to provide accurate information about the participant, oversee the administration of study drug, and participate in study visits and informant-based assessments (usually requires at least 5 hours of contact per week).

    NOTE: Other knowledgeable informants/informed caregivers may contribute to informant-based scales; however, the site should identify an informant who will be able to serve as the primary source of information.

11. As assessed by investigator, participant is likely to be able to comply with the protocol for a minimum of 2 weeks.

Exclusion Criteria

1. Use of cannabinoids or other forms of marijuana in the 3 weeks prior to Baseline, as based on self-report.
2. Suspected or known allergic reactions, adverse reactions, or hypersensitivity to cannabinoids and/or components (e.g., (<specify oil to be used in final formulation, e.g.: coconut oil; sesame oil>) of the study drug (T2:C100 or placebo).
3. Treatment with another investigational drug or other investigational intervention within the previous 30 days or five half-lives of the investigational product, whichever is longer.
4. Any condition, which in the opinion of the site PI, Data and Coordinating Center, regulatory sponsor, or Project Lead/Protocol PI, makes the participant unsuitable for inclusion.

Primary Outcome Measures

Name	Time	Method
Change from Baseline in agitation as measured by the Cohen-Mansfield Agitation Inventory (CMAI) at 2 weeks	Baseline, Day 7 and Day 14	The Cohen-Mansfield Agitation Inventory (CMAI) assesses the average frequency of manifestations of agitated behaviors in elderly persons over a 1-week period. The CMAI is a questionnaire consisting of 29 agitated behaviors, each rated on a 7-point frequency scale. In addition to the frequency of each behavior, informants/caregivers will be asked to use a 5-point scale to rate the disruptiveness of each behavior. For this study, the CMAI will target behaviors observed by knowledgeable informants/informed caregivers. Expanded descriptions of the behaviors will be provided to the informant/caregiver to be used as a reference during the interview.

Secondary Outcome Measures

Name	Time	Method
Change from Baseline in agitation as measured by the Cohen-Mansfield Agitation Inventory (CMAI) at 12 weeks	Baseline, Day 7, Day 14, Week 4, Week 8 and Week 12	The Cohen-Mansfield Agitation Inventory (CMAI) assesses the average frequency of manifestations of agitated behaviors in elderly persons over a 1-week period. The CMAI is a questionnaire consisting of 29 agitated behaviors, each rated on a 7-point frequency scale. In addition to the frequency of each behavior, informants/caregivers will be asked to use a 5-point scale to rate the disruptiveness of each behavior. For this study, the CMAI will target behaviors observed by knowledgeable informants/informed caregivers. Expanded descriptions of the behaviors will be provided to the informant/caregiver to be used as a reference during the interview.
Clinical Global Impression of Change - agitation (CGICa)	Baseline, Day 7, Day 14, Week 4, Week 8 and Week 12	The Clinical Global Impression of Change - agitation (CGICa) is similar to the mADCS-CGIC in that both versions provide a systematic method for assessing clinically significant change in clinical trials as evaluated by an experienced clinician on the basis of a clinical interview and examination. It relies on both direct examination and/or observation of the participant as well as interviews with a knowledgeable informant/informed caregiver. The participant interviews that are a part of the mADCS-GGIC are not feasible in this study population and have been eliminated in the CGICa in favor of standard administration across all participants. Anchors present in the mADCS-CGIC that are not relevant in this study population have been removed and agitation-related anchors have been added to the CGICa. A skilled and experienced clinician who is blinded to treatment assignment rates the patient on a 7-point Likert scale, ranging from 1 (marked improvement) to 7 (marked worsening).
