Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes

Eligibility
Key inclusion criteria
Inclusion Criteria - Subjects are eligible for enrollment if they meet the following criteria:

1. A confirmed diagnosis of severe chronic neutropenia based on documented absolute neutrophil counts of less than 0.5x109/L on at least three occasions in the three months prior to enrollment.
2. For subjects with presumed cyclic neutropenia, documentation of at least two neutrophil cycles is preferred. Documentation should include the nadirs with neutrophil counts of less than 200 followed by a clear increase in the counts generally to at least 500 to 1000 followed by a second nadir, usually expected to occur at about three weeks after the first nadir, i.e., cycling with a three week periodicity. Documentation with at least six weeks of counts and two expected nadirs is preferred.

Cases not showing clear oscillations will be categorized as congenital (if neutropenia or neutropenic complications appear to have occurred from birth) or idiopathic (if all symptoms in evidence point to an acquired disorder occurring after the first year of life).
3. Bone marrow aspiration consistent with the diagnosis of congenital, cyclic or idiopathic neutropenia. In all of these conditions, it is expected that the marrow aspirate evaluation at the time of neutropenia will show a deficiency of mature neutrophils. An exception is myelokathexis, a condition with large accumulations of neutrophils with pycnotic nuclei in the marrow. Bone marrow aspirates may show some dyspoiesis of the neutrophil lineage, but abnormalities of erythropoiesis or platelet formation are, in general, inconsistent with the diagnosis of SCN.
4. Normal cytogenetic evaluation. The only exception being cases of well documented severe congenital neutropenia with preferably previously documented normal cytogenetic evaluation will now be enrolled in the Registry at the time of evolution to leukemia.
5. History of recurrent infections (i.e., severe mouth ulcers, gingivitis and sinusitis).
6. Age greater than three months.
7. Independent of hematological parameters, subjects with the following diagnoses may be included: Shwachman-Diamond syndrome (SDS), glycogen storage disease type 1b (GSD1b), Barth syndrome, and Cohen's syndrome.
8. Subjects with moderately severe chronic neutropenia (i.e., ANC less than 1.0x109/L) and recurrent severe infections (i.e., deep tissue infections of subcutaneous areas, lungs, liver, etc.).
9. Immune neutropenia with positive anti-neutrophil antibodies meeting criteria in 1, 3, 5 and 6.
10. All SCN subjects originally enrolled in Amgen-sponsored SCN studies.
