Clinical Trial Summary

The goal of this study is to test Kindolor in healthy adults. The main questions it aims to answer are:

• What is the safe dose of Kindolor in healthy volunteers?

• How is Kindolor metabolized by the human body?

Participants will undergo medical tests before and after receiving Kindolor or a placebo to see if there is any difference between the groups.

Description:

Eligible participants will undergo intake procedures and baseline evaluations at the clinic the day before dosing. The next day, participants will be randomized to, and receive, either Kindolor tablets or placebo tablets (4 cohorts of escalating doses of Kindolor with 6 Kindolor participants and 2 placebo participants in each cohort). Participants will remain in the clinic for at least an additional 48-hours for safety assessments and blood collections to determine plasma levels of Kindolor, then will be discharged from the clinic and return for follow-up safety tests 7 days later.

1. Healthy male or female volunteer, ages 18-to-55 years, inclusive.

2. BMI must be between 18 and 32 kg/m2 (inclusive) and weigh a minimum of 50 kg (110 lbs). BMI is calculated as weight in kg divided by the square of height measured in meters.

3. A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile, and a 12-lead electrocardiogram (ECG).

5. If female, be postmenopausal (at least 2 years prior to dosing), surgically sterile (6 months post tubal ligation), or agree to use an acceptable form of birth control from screening until 28 days after dosing. Subjects who claim postmenopausal status will have status confirmed with a follicle-stimulating hormone (FSH) test. Acceptable forms of birth control for females include the following:

• Vasectomized partner (at least 6 months prior to dosing)

• Surgical sterilization (bilateral tubal ligation, hysterectomy, bilateral oophorectomy) at least 6 months prior to dosing

• Non-surgical permanent sterilization (eg, Essure procedure) at least 3 months prior to dosing

• Nonhormonal intrauterine device

• Abstinence (must agree to use a double barrier method if they become sexually active during the study)

6. If male, agree to use an acceptable method of birth control during the study and in the 90 days following dosing. Acceptable forms of birth control for males include the following:

• Vasectomy (at least 6 months before dosing)

• Partner is surgically sterilized (see methods above for females)

• Partner uses oral, injectable, or implantable hormonal contraceptives or intrauterine device (IUD)

• Double barrier (partner uses diaphragm with spermicide; condoms with spermicide)

• Abstinence (subject must agree to use a double barrier method if subject becomes sexually active during the study)

7. If female, agree to not breastfeed or donate ova from the time of consenting to the study and for 28 days after dosing the study drug.

8. If male, agree to not donate sperm from the time of consenting to the study and for 90 days after dosing the study drug.

9. Be able to verbalize an understanding of the consent form, able to provide written informed consent, verbalize willingness to complete study procedures, able to understand written and oral instructions in English.

10. Complete all assessments required at screening and baseline and be available to stay in the Phase I unit for a period of approximately 3 days and 2 nights and return for a follow-up visit.

11. Provide contact information of someone, such as a family member, spouse, or significant other, who may be able to contact the subject in case of a missed clinic appointment.

12. Be someone who in the opinion of the investigator would be expected to complete the study protocol.

Exclusion Criteria:

1. History of significant sensitivity to any drug.

2. Requirement for any over-the-counter and/or prescription medication, vitamins and/or herbal supplements (including cannabis and cannabis derived products, including CBD-containing products) on a regular basis or use of any of the above within the 2 weeks or 5 half-lives of the respective medication prior to study drug administration.

3. More than moderate alcohol consumption in the past 8 weeks. Moderate alcohol consumption is defined as limiting intake to 2 drinks or less in a day for men and 1 drink or less per day for women. Examples of one drink include: Beer: 12 fluid ounces (355 milliliters); Wine: 5 fluid ounces (148 milliliters); Distilled spirits (80 proof): 1.5 fluid ounces (44 milliliters).
