Study summary

This is a Phase I/II clinical trial of gene therapy for treating Fanconi anemia using a self-inactivating lentiviral vector to functionally correct the defective gene. The objectives are to evaluate the safety and efficacy of the gene transfer clinical protocol.

Read the detailed description

Fanconi anemia is a rare, inherited disease that is caused by a gene defect and that primarily affects an individual's bone marrow, resulting in decreased production of blood cells. The major problem for most patients is aplastic anemia, the blood counts for red blood cells, white blood cells, and platelets are low. In addition, some patients have physical defects usually involving the skeleton and kidneys. Fanconi anemia is typically diagnosed in childhood, and there is a high fatality rate. Hematopoietic stem cell transplantation (HSCT) is a common treatment for Fanconi anemia. However, there are many risks associated with HSCT including rejection of the transplanted cells and graft-versus-host disease.

The primary objectives are to evaluate the safety of the self-inactivating lentiviral vector, the ex vivo gene transfer clinical protocol and the efficacy of immune reconstitution in patients overcoming immune abnormalities present at the time of treatment, assessment of gene correction efficiency, and finally the long-term correction of Fanconi anemia associated disease symptoms.

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

  1. Diagnosis of Fanconi anemia FANCA type based on DNA sequencing and sensitivity test for chromosomal cleavage by mitomycin C or butylene oxide.
  2. No cytogenetic abnormalities and the proportion of myelodysplastic abnormalities does not exceed 5% within 3 months prior to stem cell collection.
  3. Age: ≥ 4 years.
  4. : ≥ 70%.
  5. ≥ 5×10\^8/L; ≥ 2×10\^10/L.
  6. ≥ 8g/dL.
  7. Proper renal and hepatic functions ( denotes "upper limit of normal range") with

    • serum creatinine ≤ 1.5×ULN;
    • serum ≤ 3×ULN;
    • /ALT ≤ 5×ULN.
  8. Pulmonary function is normal; DLCO > 50%.
  9. Written, obtained prior to any study-specific procedures.

Exclusion criteria

Exclusion Criteria:

  1. Diagnosis of active malignant disease or myelodysplastic syndrome.
  2. Diagnosis of myeloid leukemia.
  3. Pregnant or lactating females.
  4. Existence of an available HLA-identical related donor.
  5. Subject infected with (HBsAg positive), (HIV antibody positive), HTLV (HTLV antibody positive), Treponema pallidum antibody positive or TB culture positive.
  6. Patients, in the opinion of investigators, may not be eligible or not able to comply with the study.
Terms in these criteria, in plain language(10)

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.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

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.
