What this study is about
The purpose of this study is to compare how two different formulations of the study medicine (GSK5784283) move through the body over time (how the drug moves through the body \[PK\] study) in healthy adults.
View original scientific description
The purpose of this study is to compare how two different formulations of the study medicine (GSK5784283) move through the body over time (pharmacokinetic \[PK\] study) in healthy adults. The aim of the study is to see how the body processes GSK5784283 and determine if the study medicine is safe, how well it is tolerated by the body and if the study medicines being tested work in the body in the same way.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants who are healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and ECG.
- Body weight greater than or equal (\>=) 50 kilogram (kg) (110 pounds \[lbs\]) and body mass index within the range 19 to 30 kilogram per meter square (kg/m\^2) (inclusive).
- A female participant is eligible to participate if she is a participant of non-childbearing potential (PONCBP) as specified in the protocol.
- Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
Exclusion criteria
- Hypersensitivity- Participants with allergy/intolerance to any biologic therapy or any of the known excipients used in products administered subcutaneously
- History or presence of any clinically significant medical condition 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.
- Any clinically relevant abnormal findings in physical examination, hematology, clinical chemistry, urinalysis, vital signs during screening period which in the opinion of the investigator, may put the subject at risk because of his/her participation in the study, or may influence the results of the study, or the subject's ability to participate in the study.
- Live vaccine(s) within 1 month prior to screening or plans to receive such vaccines during the clinical study.
- Treatment with biologic agents (such as monoclonal antibodies including marketed drugs) within 3 months or 5 half-lives (whichever is longer) prior to study intervention administration.
- Current smokers (tobacco and/or marijuana) or former smokers with a smoking history \>10 pack-years and participants using vaping products, including electronic cigarettes.
- Regular alcohol consumption that exceeds the limits specified in the protocol
- Sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates participation in the clinical study.
- The QTc is the QT interval corrected for heart rate according to Fridericia's formula (QTcF), machine-read or manually over-read \>450 millisecond (msec).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
