Intervention/exposure
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 C is a two-sequence, two-period crossover study to compare the oral bioavailability of the EQ121 IR capsule formulation to the EQ121 ER tablet formulation, in adult healthy volunteers of Chinese descent
Sequence 1: In period 1 of Sequence 1, the participants will receive 2 oral doses of 24 mg EQ121 immediate release (IR) capsule given twice a day (e.g. 12 hours apart) on Day 1 under fasting conditions.
Sequence 2: In period 2 of Sequence 2, after completion of Period 1, following a 5-day washout period, the same participants will receive 2 oral doses of 24 mg EQ121 immediate release (IR) capsule given twice a day (e.g. 12 hours apart) on Day 7 under fasting conditions

Five (5) participants will be enrolled into each sequence

Adherence will be monitored via clinical site staff recording and reporting all number of pills taken while confined

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:

Other reasons
Sponsor has decided not to pursue Sub-study 3 Part C (Chinese Cohort) of Study EQ121-010. This results from a business decision not to evaluate the PK and tolerability of EQ121 specifically in a cohort of exclusively Chinese subjects outside of Mainland China. This decision was not because of any newly identified safety signals or safety risks associated with EQ121.
