A Phase 1 interventional study of TE-8214 - SAD and Placebo in Acromegaly, sponsored by Immunwork, Inc.. Completed at 1 site in Australia. Open to participants aged 18 Years to 64 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-05-20.

This is a Phase 1, first-in-human, randomized, double-blinded, placebo-controlled study to evaluate the safety, tolerability, and PK of TE-8214 in healthy volunteers. The study will assess single ascending doses (SAD) of TE-8214.
This study will enroll approximately 32 eligible healthy volunteers.
The main purpose of this study is to evaluate the safety, tolerability, and PK of single ascending doses (SAD) of TE-8214. This study will involve 4 groups (called Cohorts) of 8 participants at a time, with each group receiving a higher dose than the group before. A further 8 participants may be randomized into an optional cohort.
Each participant will receive 1 dose of TE-8214 solution or placebo in a randomized, double-blinded manner and the IP will be administered by subcutaneous injection into the abdomen. For each cohort, there will be a sentinel group and a main group. In the sentinel group, 2 participants will be randomized to TE-8214 or placebo at a ratio of 1:1. if there are no safety concerns this will be followed by the main group dosing at the discretion of the investigator.
The total duration of the study for each participant is up to 16 weeks which consists of 28 days for Screening, confinement period of 3 days with dosing on Day 1 and a follow up period until Day 84.
202 studies on the registry are indexed under Acromegaly; 19 are open to participants now.
This study's enrollment of 32 is below the median of 43 across 115 interventional studies indexed under Acromegaly.

Exclusion Criteria:
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.
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.
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.
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.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
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.
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.
