Study summary

This is a Phase 1a/1b, multicenter study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and clinical activity of TER-1754 (a novel AKT1 inhibitor) in patients with HHT.

Read the detailed description

This is a first-in-human, Phase 1, multicenter trial that includes two parts:

  • Phase 1a (dose escalation) will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary clinical activity of TER-1754 in patients with HHT and determine the maximum tolerated or administered dose.
  • Phase 1b (proof of concept) will evaluate clinical activity and further characterize the safety profile of TER-1754 in patients with HHT. The Phase 1b treatment period is separated into a blinded treatment segment followed by an open-label extension (OLE) segment.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Able to provide a signed and dated written prior to any study-specific procedures, sampling, or data collection.
  • A clinical diagnosis of HHT as defined by the Curaçao criteria
  • Baseline (1-month) ESS ≥ 4
  • ≤ 2
  • Anemia or parental iron infusion of at least 500 mg or transfusion of at least 2 units of RBCs within the preceding 24 weeks.
  • Adequate bone marrow function
  • Adequate renal function
  • Adequate hepatic function

Exclusion criteria

Exclusion Criteria:

  • Prior nonresponse or loss of response to an agent that inhibits AKT1 and/or AKT2 as the primary mechanism of action.
  • Diagnosis of DM requiring insulin treatment
  • Known significant bleeding sources other than nasal, GI, or menstrual/ uterine
  • Known underlying hypoproliferative anemia or hemolytic anemia
Terms in these criteria, in plain language(3)

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.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

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.
