Criteria

Inclusion Criteria:

For Part A (SAD) and Part B (MAD)

To be eligible for the study, participants must meet all of the following inclusion criteria:

1. Healthy male or female volunteers, between 18 and 55 years of age
2. Participants in good health as determined by medical history, physical examination, vital signs, ECG, and clinical laboratory tests.
3. Body Mass Index (BMI) between 20.0 and 34.9 kg/m2 (inclusive).
4. Participants who smoke no more than 2 cigarettes per day or equivalent per week (includes e-cigarettes) can be included in the study but must be willing to abstain from smoking during confinement periods.
5. Participants must have no relevant dietary restrictions,

6. Females must be non-pregnant and non-lactating, and must use an acceptable, highly effective double contraception from Screening until at least 30 days have passed since study drug administration , including the follow-up period. Double contraception is defined as a condom AND one other form of the following:

   • Established hormonal contraception (oral contraceptive pills [OCPs], long-acting implantable hormones, and injectable hormones) for at least 1 month prior to Screening
   • A vaginal ring or an intrauterine device [IUD]
   • Documented evidence of surgical sterilization at least 6 months prior to Screening (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, or bilateral oophorectomy) for women or vasectomy at least 90 days prior to Screening for men (with appropriate post-vasectomy documentation of the absence of sperm in semen), provided the male partner is a sole partner.
   • Women not of childbearing potential must be postmenopausal for ≥ 12 months. Postmenopausal status will be confirmed through testing of follicle-stimulating hormone (FSH) levels ≥ 40 IU/mL at Screening for amenorrhoeic female participants. Females who are abstinent from heterosexual intercourse will also be eligible.

   Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not considered highly effective methods of birth control. Participant complete abstinence for the duration of the study and for 1 month after the last study treatment is acceptable.

   Female participants who exclusively are in same sex relationships are not required to use contraception.

   - Males must be surgically sterile (> 90 days since vasectomy with no viable sperm), abstinent, or if engaged in sexual relations with a woman of childbearing potential (WOCBP), the participant and his partner must be surgically sterile (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or using an acceptable, highly effective contraceptive method from Screening until at least 90 days have passed since study drug administration, including the follow-up period. Acceptable methods of contraception include the use of condoms and the use of an effective contraceptive for the female partner that includes: OCPs, long-acting implantable hormones, injectable hormones, a vaginal ring, or an IUD. Participants with same sex partners (abstinence from penile-vaginal intercourse) are eligible when this is their preferred and usual lifestyle.

   WOCBP must have a negative pregnancy test at Screening and Day -1 and be willing to have additional pregnancy tests as required throughout the study.

   Males must not donate sperm for at least 90 days after the last dose of AL01211.

7. Participants must have the ability and willingness to attend the necessary visits to the CRU.
8. Must sign an informed consent form (ICF) indicating that they understand the purpose of, and procedures required for the study and are willing to participate in the study.
