1.Participants must be 18 to 55 years of age inclusive, at the time of signing the informed consent and can be included in only one cohort of this trial. 2.Participants must be healthy as determined by the Investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. 3.Body weight =50 kg and body mass index (BMI) within the range 18.5 -30 kg/m² (inclusive). 4.Male Participants: Male participants with partners of childbearing potential must use either one of the male or female condom, with the female partner using an additional highly effective contraceptive method with a failure rate of <1% per year, during the treatment period, and for at least 90 days after the last dose of trial treatment. Other acceptable methods of contraception include: •Any highly effective method of contraception listed below for female participants •Progesterone-only oral contraception, where inhibition of ovulation is not the primary mode of action •Cap, diaphragm, or sponge with spermicide For participants who practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant, contraceptive requirements do not apply. Male participants should refrain from donating sperm during the treatment period and for at least 90 days after the last dose of trial treatment. For participants who are exclusively in same-sex relationships, contraceptive requirements do not apply. 5.Female Participants: Female participants who are of non-childbearing potential (i.e., due to being post menopausal for at least 1 year (confirmed by FSH assessment) or permanently sterile following hysterectomy, bilateral salpingectomy, bilateral oophorectomy) will not be required to use contraception. Female participants of childbearing potential must be willing to use a highly effective method of birth control (i.e. contraceptive measure with a failure rate of <1% per year when used consistently and correctly, as per described in protocol) with low user dependency, in conjunction with a barrier contraception (i.e. either one of the male or female barrier contraceptions) from the time of screening until 30 days after the final Follow up Visit. Use of any of the protocol defined contraception should have been established for at least 90 days prior to enrolment (the investigator should evaluate the potential for contraceptive method failure (e.g. non-compliance, recently initiated) in relationship to the first dose of trial treatment. Highly effective methods of contraception include: •Placement of intrauterine device or intrauterine system. •Established use of oral, injected or implanted hormonal methods of contraception associated with inhibition of ovulation. •Male sterilisation (with the appropriate post-vasectomy confirmation of surgical success). For female participants on the trial, the vasectomised male partner should be the sole partner for that participant. •Bilateral tubal ligation For participants who practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant, contraceptive requirements do not apply. For participants who are exclusively in same-sex relationships, contraceptive requirements do not apply.6.Willing to participate in the trial and capable of giving signed informed consent.
