Researchers look for people who fit a certain description, called eligibility criteria. See if you qualify.

Inclusion criteria

Healthy male or female subjects ≥18 years and ≤55 years of age on the day of ICF signing.

Subjects must be White (participants from Europe, Middle East, North Africa, Australia, and New Zealand are permitted), with biological parents and both sets of biological grandparents also be White;

Male subjects must have a body weight ≥50 kg and female subjects must have a body weight ≥45 kg. Body mass index (calculated as weight [kg]/height [m]2) must be ≥18.0 and ≤ 32.0 kg/m2;

Willing to use an adequate method of contraception, and do not plan to become pregnant, impregnate a partner, or donate sperm or ova throughout the study and for 3 months following the end of the study. Abstinence is an acceptable method of contraception provided it aligns with the preferred and usual lifestyle of the subject. Female subjects of nonchildbearing potential and subjects who are exclusively in same-sex relationships are exempt from contraception requirements. An adequate method of contraception is defined as: a)For female subjects, an adequate method of contraception is defined as the use of a condom by the male partner combined with the use of a highly effective method of contraception. The following are considered as highly effective methods of contraception: i)A nonhormonal intrauterine device; ii)Bilateral tubal occlusion (e.g. Essure-non-surgical sterility procedure and Bilateral tubal ligation), and/or a vasectomized partner with documented azoospermia 90 days after procedure, if that partner is the sole sexual partner; b)For male subjects, an adequate method of contraception is defined as use of a condom combined with the use of a highly effective method of contraception by the female partner of childbearing potential. A highly effective method of contraception is i)Oral contraceptives containing combined estrogen and progesterone, a vaginal ring, injectable and implantable hormonal contraceptives, intrauterine hormone-releasing system (e.g. Mirena) and progestogen-only hormonal contraception associated with inhibition of ovulation; ii)A hormonal or nonhormonal intrauterine device; iii)Bilateral tubal occlusion including bilateral tubal ligation, and/or a vasectomized subject with documented azoospermia 90 days after procedure, if that partner is the sole sexual partner;
