Study type
Interventional
Description of intervention(s) / exposure
EQ121 immediate release (IR) capsule is an oral solid dosage form manufactured at strengths of 1 mg and 12 mg.
Each EQ121 capsule contains EQ121 drug substance; mannitol, pregelatinized starch and microcrystalline cellulose as diluents; croscarmellose sodium as disintegrant; colloidal silicon dioxide as glidant; and magnesium stearate as lubricant

Part A: It is a single-sequence, two-period crossover, multi-cohort study to evaluate the EQ121 immediate release (IR) capsule formulation and up to 10 different EQ121 extended release (ER) tablet formulations under fasted conditions in adult healthy volunteers
Cohort 1: In period 1 of cohort 1, the participants will receive a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.
Cohort 2: In period 1 of cohort 2, the participants will receive a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.
Cohort 3: In period 1 of cohort 3, the participants will receive a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.
Cohort 4: In period 1 of cohort 4, the participants will receive a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.
Cohort 5: In period 1 of cohort 5, the participants will receive a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.

If necessary, up to 5 additional cohorts (Cohorts 6 through 10), consisting of 4 participants per cohort, may be enrolled (for a total of up to 10 cohorts), either in parallel or sequentially, to evaluate additional EQ121 ER tablet formulations or dose levels. The dose for subsequent cohorts (6 through 10) will remain a single oral dose of 36 mg EQ121 immediate release (IR) capsule on the morning of Day 1 under fasting conditions.

Each cohort will enrol distinct group of participants
Adherence will be monitored via clinical site staff recording and reporting all number of pills taken while confined

Period 2 of cohort 1: Following a 1-day washout period, the same 4 participants will receive a single oral dose of 40 mg EQ121 extended release (ER) tablet Formulation 1 on the morning of Day 3 under fasting conditions.

Period 2 of cohort 2: Following a 1-day washout period, the same 4 participants will receive a single oral dose of 40 mg EQ121 extended release (ER) tablet Formulation 2 on the morning of Day 3 under fasting conditions.

Period 2 of cohort 3: Following a 1-day washout period, the same 4 participants will receive a single oral dose of 40 mg EQ121 extended release (ER) tablet Formulation 3 on the morning of Day 3 under fasting conditions.

Period 2 of cohort 4: Following a 1-day washout period, the same 4 participants will receive a single oral dose of 40 mg EQ121 extended release (ER) tablet Formulation 4 on the morning of Day 3 under fasting conditions.

Period 2 of cohort 5: Following a 1-day washout period, the same 4 participants will receive a single oral dose of 40 mg EQ121 extended release (ER) tablet Formulation 5 on the morning of Day 3 under fasting conditions.

If necessary, up to 5 additional cohorts (Cohorts 6 through 10), consisting of 4 participants per cohort, may be enrolled (for a total of up to 10 cohorts), either in parallel or sequentially, to evaluate additional EQ121 ER tablet formulations or dose levels. The dose for subsequent cohorts (6 through 10) may be increased, decreased, or repeated based on emerging pharmacokinetic data. However, the highest dose will not exceed 80 mg.

Each EQ121 tablet contains EQ121 drug substance; lactose monohydrate as diluent; fumaric acid and tartaric acid as acidulant; hydroxypropyl methylcellulose (HPMC) as matrix; colloidal silicon dioxide as glidant; and magnesium stearate as lubricant. Each formulation will be made up of 15% W/W EQ121 drug substance and differing amounts of the excipients listed above.

• Postmenopausal status confirmed by serum FSH concentration at Screening greater than 40 mIU/mL
c. Women of childbearing potential (WOCBP):
• Must not have a positive serum pregnancy test at Screening and must have a negative urine pregnancy test on admission
• Must use at least one of the following protocol-specified highly effective methods of birth control, AND must agree to use barrier contraception (male condom) during heterosexual intercourse, from the time of Screening until at least 30 days after the last dose of study drug:
• Partner vasectomy (at least 6 months prior to Screening; vasectomized partner should be the sole partner of the female participant)
• Combined (estrogen and progestogen containing) hormonal contraception (oral, intravaginal, transdermal, injectable)
