Inclusion Criteria

Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and without history of any of the conditions listed in the exclusion criteria
Participants having body weight of ≥50 kilogram (kg) and <100 kg
Participants having a clinical laboratory profile within the normal range or must have results that do not show clinically significant abnormalities, as judged by the investigator at screening
Contraceptive use by men or women participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
Participants who are female at birth are eligible to participate if at least one of the
following conditions applies
Not pregnant or breastfeeding and at least one of the following conditions applies
Is not a participant of childbearing potential (POCBP) or Is a POCBP and agree to use an
acceptable contraceptive method as described in Section 10.4 from 3 weeks prior to the
start of this study and during the study. The investigator should evaluate the
effectiveness of the contraceptive method in relationship to the first dose of study
A POCBP must have a negative highly sensitive serum pregnancy test on Day -1, prior to the
first dose of study intervention All participants in the study should be counseled on safer
sexual practices including the use and benefit/risk of effective barrier methods (e.g
male condom)
The investigator is responsible for review of medical history, menstrual history, and
recent sexual activity to decrease the risk for inclusion of a POCBP with an early
undetected pregnancy
Capable of giving written informed consent

Exclusion Criteria

Hypertension that is not well controlled
History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal
endocrine, hematological, or neurological disorders capable of significantly altering
the absorption, metabolism, or elimination of drugs; constituting a risk when taking
the study intervention or interfering with the interpretation of data
Positive human immunodeficiency virus (HIV) antibody test
Positive test result for SARS-CoV-2
Evidence of hepatitis B (HB) virus infection at screening or within 3 months prior to
first dose of study intervention Participants positive for Hepatitis B antigen (HBsAg)
are excluded. Participants negative for anti-HBs but positive for anti-HBc (negative
HBsAg status) and positive for Hepatitis B virus (HBV) DNA are excluded
Any history of a severe allergic reaction with generalized urticaria, angioedema or
anaphylaxis within the 2 years prior to enrollment that has a reasonable risk of
recurrence during the study
The participant has an underlying skin disease or disorder (i.e., infection
inflammation, dermatitis, eczema, drug rash, drug allergy, psoriasis, food allergy
urticaria) or tattoos that would interfere with assessment of injection sites
History of sensitivity to any of the study medications or their components or drugs of
their class, or a history of drug or other allergy that, in the opinion of the
investigator or medical monitor, contraindicates their participation

corticosteroids, or severe post-treatment hypersensitivity reactions (including, but
not limited to, erythema multiforme major, linear immunoglobulin A, dermatosis, toxic
epidermal necrolysis, and exfoliative dermatitis)

Receipt of any investigational study agent within 28 days prior to first dose of study
Prior exposure to VH3810109 or rHuPH20 in this or another clinical study
Where participation in the study would result in donation of blood or blood products
in excess of 500 milliliter (mL) within 56 days
Exposure to more than 4 new chemical entities within 12 months prior to the first
dosing day
ALT ≥1.5 times the upper limit of normal (ULN)
Total bilirubin ≥1.5 times the ULN (isolated total bilirubin >1.5×ULN is acceptable if
total bilirubin is fractionated and direct bilirubin <35%)

Corrected QT interval Fridericia's formula (QTcF)>450 millisecond (msec) for males and
QTcF >470 msec for females
The participant has a tattoo or other dermatological condition overlying potential
injection sites that may interfere with interpretation of ISRs or administration of
Grade 4 laboratory abnormalities

investigator would jeopardize the safety or rights of the subject including (but not
limited to): diabetes mellitus type I, chronic hepatitis; OR clinically significant
forms of drug or alcohol abuse, asthma, autoimmune disease, psychiatric disorders
