What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This Phase 2 trial tests a combination of horse anti-thymocyte globulin, cyclosporine, steroids, and growth factors in 140 adults with aplastic anemia or low-risk myelodysplastic syndrome (MDS). The goal is to see if this immune-suppressing and blood-cell-boosting approach can improve blood counts and reduce transfusion needs. Participants must be 18 or older and not eligible for a stem cell transplant.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
horse anti-thymocyte globulin (hATG), cyclosporine, methylprednisolone, and filgrastim or pegfilgrastim
What this could lead to
If successful, this combination could improve blood cell counts and reduce the need for transfusions in people with aplastic anemia or low-risk MDS.
What could go wrong
This is an early Phase 2 trial with only 140 participants, so results may not apply to everyone. The treatment suppresses the immune system, which can increase the risk of serious infections.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients with the diagnosis of MDS (Low, Int-1 by IPSS, or hypocellular) who are either previously treated or untreated are eligible for this trial. 2. Patients with the diagnosis of aplastic anemia who are either previously treated or untreated are eligible if they are not currently candidates for an allogeneic stem cell transplant. 3. Patients ages 18 years and older are eligible 4. Patients must have been off of cytotoxic, immunosuppressive (except steroids), or targeted therapy for at least 2 weeks prior to entering this study, and have recovered from the toxic effects of that therapy to grade 1 or less. 5. Adequate organ function as defined below: * liver function (bilirubin \< 2mg/dL, AST \<3 x ULN) * kidney function (creatinine \< 2.5 x ULN ). 6. ECOG performance status of ≤ 2. 7. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. 8. A negative urine pregnancy test is required within 1 week for all women of childbearing potential prior to enrolling on this trial. 9. Patient must have the ability to understand the requirements of the study and signed informed consent. A signed informed consent by the patient or his legally authorized representative is required prior to their enrollment on the protocol. 10. Patients should have an indication for therapy for their disease such as transfusion dependence or morbidity associated with their cytopenia(s) such as bleeding, severe fatigue, or frequent/multiple infections (eg. neutropenia). Exclusion Criteria: 1. Pregnant women are excluded from this study. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study agents, breastfeeding should be discontinued if the mother is treated on this study. 2. Known HIV infection. 3. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. 4. Patient with documented hypersensitivity to any of the component medications.
