Study summary

This study with ALTB-268 will determine the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple ascending doses of ALTB-268 in healthy volunteers.

Read the detailed description

This is a Phase I, first-in-human, randomized, double-blind, single and multiple ascending dose study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of subcutaneously administered ALTB-268 in healthy volunteers. Up to 40 and 24 healthy volunteers will be recruited in single and multiple ascending doses, respectively.

The primary objective is to assess the safety and tolerability of subcutaneously (sc) administered ALTB-268 in healthy volunteers. The secondary objective is to assess the plasma pharmacokinetics of sc administered ALTB-268 in healthy volunteers. The exploratory objectives are to assess the pharmacodynamics and evaluate immunogenicity of sc administered ALTB-268 in healthy volunteers.

Inclusion criteria

  1. Written and willingness to comply with the study restrictions.
  2. Sex: male or female volunteers.
  3. Age: 18 to 55 years, inclusive, at screening.
  4. (BMI): 18.0 to 32.0 kg/m2, inclusive, at screening.
  5. Weight: 50 kg to 110 kg, inclusive, at screening.
  6. Healthy volunteers: Healthy status as defined by the absence of evidence of any , in the opinion of the Investigator, active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead , hematology, blood chemistry, serology, and urinalysis

Exclusion criteria

Exclusion Criteria:

  1. Males with female partners who are pregnant, lactating, or planning to become pregnant during this study or within 90 days after dosing of study drug.
  2. Use of any drug or device within 30 days or five half-lives whichever is longer, of the first dose of study drug.
  3. Any disease which, in the opinion of the Investigator, poses an unacceptable risk to the volunteers.
  4. history of any drug sensitivity, drug allergy, or food allergy, as determined by the Investigator (such as anaphylaxis, hepatotoxicity, or treatment with or epinephrine). Confirmatory circumstances would include treatment with epinephrine or in emergency department.
Terms in these criteria, in plain language(6)

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.

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.

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.

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.

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.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Incidence of ALTB-268 Treatment-Emergent Adverse Events

    Adverse events (AEs) - severity of the AEs will be graded using the most current version of the Common Terminology Criteria for AE (CTCAE) (V5.0) 5-point scale. The relationship between AEs and the study drug will be indicated as related or not related.

    Time frame: through study completion, up to day 120 of the study

Secondary outcomes

  1. Pharmacokinetics of ALTB-268 AUC (PK) of sc administered ALTB-268 in healthy volunteers.

    Including AUC0-t, AUC0-inf, AUC0-tau

    Time frame: through study completion, up to day 120 of the study

  2. Pharmacokinetics of ALTB-268 Cmax

    Maximum plasma concentration

    Time frame: through study completion, up to day 120 of the study

  3. Pharmacokinetics of ALTB-268 tmax

    Time to reach Cmax

    Time frame: through study completion, up to day 120 of the study

  4. Pharmacokinetics of ALTB-268 t1/2

    Half life

    Time frame: through study completion, up to day 120 of the study

  5. Pharmacokinetics of ALTB-268 CL/F

    Apparent clearance, calculated as dose/AUC0-inf

    Time frame: through study completion, up to day 120 of the study

  6. Pharmacokinetics of ALTB-268 Rac

    The ratio of accumulation of a drug after repeated administration as compared to a single dose, PART B only

    Time frame: through study completion, up to day 120 of the study

Other outcomes

  1. Pharmacodynamics of ALTB-268 Receptor Occupancy

    Receptor Occupancy will be measured using a flow cytometry based method

    Time frame: through study completion, up to day 120 of the study

  2. Exploratory Immunophenotyping Lymphocyte subsets

    Lymphocyte subsets, T,B and NK cells will be assessed using a flow cytometry based method

    Time frame: through study completion, up to day 120 of the study

  3. Pharmacodynamics - change in target engagement biomarkers

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 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
