Eligibility
Key inclusion criteria
Key

1. Healthy, in the opinion of the Investigator, as determined by medical evaluation
including medical history, physical examination, laboratory tests, vital signs, and
12-lead ECGs. A subject with a clinical abnormality or laboratory parameter(s) outside
the reference range for the population being studied that is not specifically listed
in the inclusion or exclusion criteria may be included if the Investigator (in
consultation with the Medical Monitor) agree and document that the finding is unlikely
to introduce additional risk factors and will not interfere with the study procedures
or data interpretation.

2. Between 18 and 55 years of age inclusive, at the time of signing the informed consent.

3. Body weight at screening = 40 kg and < 120 kg, with body mass index between 18 and 30
kg/m2.

4. Capable of giving signed informed consent, which includes compliance with the
requirements and restrictions listed in the informed consent form and in this
protocol, including the protocol-mandate hospitalization.

5. Use of a highly effective contraceptive measure (< 1% failure rate; see Section 13.1)
for all males and all females of childbearing potential during study and 90 days post
dose for males and 30 days post dose for females. Females of childbearing potential
need to have a confirmatory urine pregnancy test on Day -1. Females who are not of
childbearing potential (i.e., who are considered to be post-menopausal [= 12 months of
non-therapy amenorrhea] or surgically sterile [absence

Can healthy volunteers participate?
Yes
Key exclusion criteria
1. History or presence of a disease or condition that, in the Investigator's opinion,
constitutes a risk when taking study drug or interfering with study assessment or
interpretation of the data (e.g., autoimmune disease). Subjects post cholecystectomy
are acceptable. Subjects with resolved childhood asthma not requiring prescription
medicine are acceptable. Subjects with Gilbert's disease are acceptable if total
bilirubin =3× ULN.

2. Medical history of severe allergic reaction, angioedema, anaphylaxis, clinically
significant drug hypersensitivity reaction, or autoimmune or immunodeficiency
disorder.

3. Active infection or a history of serious infections as follows:

1. Use of antimicrobials (antibacterials, antivirals, antifungals, or antiparasitic
agents) for an infection within 30 days before first dose. Topical treatments may
be allowed at the Medical Monitor's discretion.

2. History of opportunistic infections in the last 2 years.

3. Recurrent or chronic infection, or other active infection, that in the opinion of
the Investigator might cause this study to be detrimental to the subject.

4. Symptomatic herpes zoster within 3 months prior to screening.

5. History of tuberculosis (active or latent) irrespective of treatment status.

6. Any history of viral hepatitis: hepatitis B virus, hepatitis C virus (HCV),
hepatitis E virus.

HCV is acceptable if HCV RNA is undetectable for at least 3 months post
completion of direct-acting antiviral therapy.

7. Any known history of John Cunningham virus (JCV) infection or progressive
multifocal leukoencephalopathy (PML).

4. Any planned major surgical procedure during the study.

5. History of malignant neoplasm within the last 10 years, except for fully treated
nonmetastatic basal or squamous cell cancers of the skin (within 3 years) that shows
no evidence of recurrence.

6. Use of prescription or non-prescription drugs (including recreational drugs and herbal
medications) within 7 days or 5 half-lives (whichever is longer) prior to dosing,
unless in the opinion of the Investigator (in consultation with the Medical Monitor),
the medication will not interfere with the study or compromise subject safety.
Paracetamol (acetaminophen) at doses of = 4 grams/day, and occasional use of
non-steroidal anti-inflammatory drugs at licensed doses, are permitted.

7. Live or live-attenuated vaccination within 4 weeks of Day 1, or plan to receive a live
vaccination during the study until follow-up.

8. Previous exposure to DR-0201, or known hypersensitivity to biologics.

9. Prior anaphylaxis to a biological agent or vaccine.

10. Neutrophil or lymphocyte counts below the normal range.

11. Estimated glomerular filtration rate by Chronic Kidney Disease Epidemiology
Collaboration equation calculation = 90 mL/min/1.73 m2 at screening.

12. Alanine transaminase > 2× upper limit of normal (ULN) and bilirubin > 1.5 × ULN
(isolated bilirubin > 1.5 × ULN is acceptable if bilirubin is fractionated and direct
bilirubin < 35%) at screening. Bilirubin > 3 × ULN if known Gilbert's disease.

13. Other clinically significant abnormalities of laboratory assessments, as judged by the
Investigator and/or Medical Monitor, that could affect the safety of the subject, or
the interpretation of the data from the study.

14. Positive serology for human immunodeficiency virus (HIV) at screening.

15. Positive drug/alcohol screen at screening or baseline.

16. QT interval corrected for heart rate (QTc) > 450 msec, based on the mean of triplicate
ECGs. The QTc is the QT interval corrected using Fridericia's formula (QTcF; preferred
method), or another method, machine or overread.

17. Seated blood pressure is less than 90/40 mmHg or greater than 140/90 mmHg at
screening. Heart rate is lower than 40 bpm or higher than 100 bpm at screening.

18. Participation in a clinical trial and has received an investigational product within
the following time period prior to screening in the current study: 3 months (for
biologic therapies) or 1 month (for non-biologic therapies), 5 half-lives, or twice
the duration of the biological effect of the investigational product (whichever is
longer).

19. Exposure to more than 4 new chemical entities within 12 months prior to the first
dosing day.

20. Participation in a clinical study resulting in loss of blood or blood products in
excess of 500 mL within 3 months prior to enrollment.

21. Any other medical or psychiatric condition, or laboratory abnormality that would, in
the opinion of the Investigator or Medical Monitor, increase the subject's risk of
participation, jeopardize completion of the study, or compromise interpretation of the
study data. Subjects receiving systemic medication for depression are not acceptable

22. Unstable lifestyle factors (including but not limited to excessive alcohol use, heavy
nicotine use, or substance abuse), to the extent that in the opinion of the
Investigator they would interfere with the ability of a subject to complete the study.
Up to four units of alcohol per week are allowed once the in-patient period is
complete.
