Outcome Measures

Primary Outcomes (1)

  • Frequency, grade and relationship to STM-01 of unsolicited local and systemic AEs (any SAEs, MAAEs and AESIs ) during the 60-d follow-up period post IV infusion at D0 and D28 per the CTCAE v5.0 and clinical-safety laboratory parameters up to D 56.

    Dose 1 (Day 0) till end of study (Day 56)

Study Arms (1)

Dose arm (2 cohorts; 2 doses)

OTHER

Up to 12 participants will be enrolled (Up to 6 participants, for 5 completers per cohort). Each successive cohort of participants will receive STM-01 at the following doses: 100.0 x 106 nMSCs, and 200.0 x 106 nMSCs.

Drug: STM01

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Stable New York Heart Association (NYHA) Class II or III HF diagnosis, evident at least 6 months prior to enrolment as confirmed by medical history.
  • Documented prior objective evidence of heart failure
  • Screening ejection fraction ≥50%.
  • Adequate bone marrow reserve and organ function at the Screening
  • Receiving standard of care heart failure therapy at stable doses for at least 30 days prior to Screening.

You may not qualify if:

  • Participant in any other study and has received any other investigational drug within 30 days prior to screening or 5-half-lives, whichever is longer, or any other investigational implanted device within 30 days prior to screening, or are taking part in a nonmedication study which, in the opinion of the Investigator, would interfere with study compliance or outcome assessments.
  • Prior diagnosis of hypertrophic cardiomyopathy or a known infiltrative or storage disorder causing HFpEF and/or cardiac hypertrophy, such as amyloidosis, Fabry disease, or Noonan syndrome with LV hypertrophy.
  • Persistent or permanent atrial fibrillation and is not therapeutically anticoagulated for at least the 4 weeks prior to the initial screening visit or is not adequately rate controlled within 6 months prior to informed consent according to investigator discretion.
  • Other medical or psychiatric conditions that, in the opinion of the Investigator, would preclude obtaining voluntary consent/assent or would confound the objectives of the study.
