Eligibility criteria

Key Inclusion Criteria:

  • Healthy males or healthy females of non- (WoNCBP) aged 18 to 55 years inclusive, with a >18.5-\<30kgm2 and body weight ≥50kg.
  • Healthy on the basis of a clinical history, physical examination, (ECG), vital signs and laboratory tests of blood and urine.
  • Willingness to comply with requirements or the trial, including requirements.
  • Able to give fully .

Key Exclusion Criteria:

  • Confirmed current Coronavirus Disease 2019 (COVID 19) infection before randomisation.
  • Clinical signs and symptoms consistent with COVID 19 (e.g. fever, dry cough, dyspnoea, sore throat, or fatigue) or confirmed infection by appropriate laboratory test within the last 4 weeks prior to Screening or on admission.
  • Suffered from severe course of COVID 19 (extracorporeal membrane oxygenation (ECMO), mechanically ventilated).
  • Receipt of any medicinal product (IMP) in a clinical research study within the previous 3 months (or 5 half-lives, whichever is longer) of Screening.
  • Any abnormalities on 12-lead ECG or BP at Screening (as specified).
  • History of any drug or alcohol abuse in the past 2 years.
  • Vital signs outside the normal range for healthy volunteers
  • abnormal biochemistry, haematology, coagulation, or urinalysis
  • Abnormal renal function, hepatic function or history of abnormal hepatic function occurring during treatment with investigational or licensed drugs, which led to permanent discontinuation of treatment.
  • Positive surface antigen (HBsAg), virus antibody (anti HCV), or (HIV)
  • History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or gastrointestinal disease, neurological or psychiatric disorder, or current hepatic renal dysfunction as judged by the investigator.

  • Failure to satisfy, in the Investigator's judgement, the subject's fitness to participate for any other reason, including previous serious adverse reaction or serious reactions to any drug or formulation administered parenterally or orally.
  • All female subjects must have a negative serum and urine pregnancy test at Screening and admission, respectively.
Terms in these criteria, in plain language(12)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

  2. Part 1 and Part 2: Tmax

    Plasma pharmacokinetic parameter: time to Cmax of HTL0022562 Plasma pharmacokinetic parameter: time to Cmax of HTL0022562

    Time frame: Part 1 up to Day 8, Part 2 up to Day 15

  3. Part 1 and Part 2: Area Under Curve (AUC)

    Plasma pharmacokinetic parameter: Area under the plasma concentration versus time curve derived from systemic concentrations of HTL0022562

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 20, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
