Who may be able to join

  • Patients must have a confirmed diagnosis of inherited metabolic disorder / inborn error of metabolism. Diagnosis should be confirmed by appropriate test(s) (enzyme and/or mutation analysis) before study entry. Patients must not be eligible for myeloablative chemotherapy as a preparative regimen for transplant due to age, co-morbidities or organ dysfunction.

  • Hurler Syndrome (MPS I)
  • Hurler-Scheie Syndrome with early neurologic involvement and/or sensitization to ERT

  • Creatinine less than or equal to 2.0 mg/dl and creatinine clearance ≥60 cc/min/1.73m2. Newborns must have a creatinine clearance ≥ 25 cc/min. For babies less than or equal to 3 months of age, the raw value on glomerular filtration rate (GFR) must be ≥ 1 cc/kg/min.
  • Hepatic transaminases (ALT/AST) 2.5 x normal, bilirubin <2.0mg/dl

  • Pulmonary function tests (PFTs) demonstrating forced expiratory volume at one second (FEV1) of ≥50% of predicted for age. If child is too young or unable to perform PFTs, crying vital capacity result of >50% of normal value for age or resting pulse oximeter >92% on room air or clearance by pulmonologist will be required.
  • Patient must have a related donor (identical or mismatched for 1, 2 or 3 Human Leukocyte Antigen (HLA)-A, -B or -DR loci).
  • Patient, and parent, or legal guardian must have given written informed consent according to FDA guidelines.
  • Patients must have a minimum life expectancy of at least 6 months.
  • Female patients of childbearing potential cannot be pregnant or lactating/breast-feeding and must be either surgically sterile, postmenopausal (no menses for the previous 12 months), or must be practicing an effective method of birth control as determined by the investigator (e.g., oral contraceptives, double barrier methods, hormonal injectable or implanted contraceptives, tubal ligation, or partner with vasectomy).
  • There is no upper or lower age limit for this study.

Who cannot join

  • Patients with uncontrolled seizures, apnea, evidence of recurrent or uncontrolled aspiration, or need for chronic mechanical ventilation.
  • Patients with allogeneic stem cell transplant with cytoreductive therapy in the past 6 months.
  • Subjects must not have had previous radiation therapy that would preclude total body irradiation (TBI) (as determined by radiation therapist)
  • Uncontrolled infection or severe concomitant diseases, which in the judgment of the Principal Investigator, could not tolerate reduced intensity transplantation.
  • Subjects with a positive human immunodeficiency virus (HIV) antibody test result
  • Subjects who are pregnant, as indicated by a positive serum human chorionic gonadotropin (HCG) test
Show all 11Show fewer
  • Subjects whose only donor is pregnant at the time of intended transplant
  • Subjects of childbearing potential who are not practicing adequate contraception as defined by the investigator at the site
  • Jehovah's witnesses being unwilling to be transfused
  • Patients that have any comorbid condition which, in the view of the Principal Investigators, renders the patient at too high a risk from treatment complications and regimen related morbidity/mortality.
  • Lack of related donors

About this study

The goal of this research study is to establish chimerism and avoid graft-versus-host-disease (GVHD) in patients with inherited metabolic disorders.

Read the detailed description

The objective for the study is to establish chimerism following reduced intensity conditioning with no grade III/IV GVHD. The primary endpoint we will follow is production of the missing enzyme at ≥ 10% of the normal level at day 180 post-transplant in > 90% of patients.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing hematopoietic stem cell infusion in people with Hurler Syndrome (MPS I) and Hurler-Scheie Syndrome, run by Talaris Therapeutics Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 24 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 12 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: company did not pursue this indication). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Production of missing enzyme at levels greater than or equal to 10% of normal (time frame: Day 180 post transplant to three years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2023.
