Study summary

The purpose of this study is to evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of multiple doses of HTX-001 in human adult participants.

Read the detailed description

HTX-001 is an investigational antisense oligonucleotide (ASO) administered subcutaneously. The purpose of this study is to evaluate safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of multiple doses of HTX-001. This will evaluate multiple doses of HTX-001 in participants with symptomatic nonobstructive hypertrophic cardiomyopathy (nHCM) who are receiving standard of care therapy.

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

  • Diagnosis of nHCM
  • On a stable regimen of guideline-directed medical therapy for nHCM
  • functional class II or III
  • NT-proBNP >300 pg/mL
  • Body weight of 50 to 100 kg, inclusive, and ≤40 kg/m2, inclusive
  • Adequate renal function
  • Not pregnant, and willing to use acceptable methods
  • Able and willing to comply with study procedures

Exclusion criteria

Exclusion Criteria:

  • Any evidence of left ventricular outflow tract obstruction (LVOTO)
  • Implantation of an implantable cardioverter-defibrillator (ICD) within 6 months
  • History or current evidence of a or uncontrolled underlying condition
  • Unable to tolerate subcutaneous dosing
  • Any reason that in the opinion of the Investigator would lead to the inability of the participant to comply with the protocol
Terms in these criteria, in plain language(4)

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

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.

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.

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.

5 registry updates since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2026 (actual). Primary completion is estimated for Mar 2027, 5 months after the start.

Of 12 phase 1 interventional studies under Cardiomyopathy, Hypertrophic, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 12. This study's planned 5 months is close to that.

How these figures are worked out, and which studies are left out of them.

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.
