Vinblastine/Prednisone Versus Single Therapy With Cytarabine for Langerhans Cell Histiocytosis (LCH)
What this study is about
Langerhans Cell Histiocytosis (LCH) is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAF gene.

Langerhans Cell Histiocytosis (LCH) is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAF gene. These changes may make the LCH cells grow and multiply quickly.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patient must have biopsy-confirmed diagnosis of Langerhans cell histiocytosis. 2. Patient must be between 0-21 years of age. 3. Patient must have a Karnofsky performance score ≥ 50% or Lansky performance score ≥ 50%.
Exclusion criteria
- Patient may not have received any prior systemic cytotoxic or other chemotherapies for LCH or any other malignant disorder prior to the initiation of protocol therapy on TXCH LCH0115 with the exception of: Steroid pretreatment: Systemic glucocorticosteroids (prednisone, methylprednisone, dexamethasone, etc.) for less than or equal to 120 hours (5 days) in the 7 days prior to initiating protocol therapy or for less than or equal to 336 hours (14 days) in the 28 days before the initiation of protocol therapy does not affect eligibility. The dose of steroid previously given does not affect eligibility. Patients who have only received surgical or radiation therapy, intralesional injection of steroids, inhalational steroids,

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
