Study of TL-895 for Patients with Relapsed or Refractory Myelofibrosis or Indolent Systemic Mastocytosis

2 1

What is this study about?

This clinical trial is focused on studying the effects of a medication called TL-895 in individuals with certain blood-related conditions. The diseases being studied are Myelofibrosis and Indolent Systemic Mastocytosis. Myelofibrosis is a disorder where scar tissue forms in the bone marrow, affecting blood cell production. Indolent Systemic Mastocytosis is a condition where there is an abnormal accumulation of mast cells, a type of white blood cell, in various tissues. The medication TL-895 is taken orally in the form of a film-coated tablet.

The purpose of this study is to determine the appropriate dose and schedule for TL-895 in treating these conditions. Participants in the study will receive either the medication or a placebo. The study will be conducted over a period of time, during which participants will be monitored for changes in their symptoms and overall health. The study aims to find out if TL-895 can improve symptoms and reduce the size of the spleen in patients with Myelofibrosis, as well as assess changes in symptoms for those with Indolent Systemic Mastocytosis.

Throughout the study, participants will be regularly assessed to ensure their safety and to evaluate the effectiveness of the treatment. The study will help determine if TL-895 is a viable treatment option for these conditions and will provide valuable information on how best to use the medication in future treatments. The trial is expected to conclude by the end of 2025.

1 joining the study

Upon joining the study, participation is confirmed based on specific criteria related to age, diagnosis, and health status.

Eligibility is determined by a confirmed diagnosis of either myelofibrosis or indolent systemic mastocytosis.

2 initial assessment

An initial assessment is conducted to evaluate symptoms and overall health.

This includes a review of medical history and current symptoms.

3 medication administration

The medication TL-895 is administered in the form of a film-coated tablet.

The route of administration is oral, meaning the tablet is taken by mouth.

4 dose determination

The study aims to determine the recommended phase 2 dose and schedule of TL-895.

This involves monitoring the effects of the medication over time.

5 symptom monitoring

Symptoms are monitored regularly to assess any changes or improvements.

For Cohorts 1-3: You must have adequate blood, liver, and kidney functions.
For Cohorts 1-3: You should have symptoms of Myelofibrosis (MF) with at least 2 symptoms scoring an average of at least 1 on a specific symptom assessment form (MFSAF v4.0) during the week before starting the study.
For Cohort 3 only: You must be ineligible for JAK inhibitor treatment and have a platelet count between 25 and 50 x 10⁹/L. Platelets are cells in your blood that help with clotting.
For Cohort 5: You need a confirmed diagnosis of Indolent Systemic Mastocytosis (ISM) based on a review of your bone marrow biopsy pathology report results, following WHO diagnostic criteria.
For Cohort 5: You must have moderate-to-severe symptoms.

Who Cannot Join the Study?

Investigated Drugs:

1-4-{[6-Amino-5-(4-Phenoxy-Phenyl)-Pyrimidin-4-Ylamino]-Methyl}-4-Fluoro-Piperidin-1-Yl)-Propenone

TL-895 is an investigational medication being studied for its potential use in treating certain types of myelofibrosis and indolent systemic mastocytosis. Myelofibrosis is a rare type of bone marrow cancer that disrupts the body’s normal production of blood cells. This medication is being tested in patients who have not responded well to other treatments or who cannot tolerate other medications. The study aims to find the best dose and schedule for using TL-895 to help improve symptoms in these patients.

Investigated Diseases:

Indolent systemic mastocytosis

Myelofibrosis – Myelofibrosis is a rare bone marrow disorder where the marrow is replaced by fibrous tissue, leading to a decrease in blood cell production. This condition often results in anemia, fatigue, and an enlarged spleen. Over time, the body’s ability to produce blood cells diminishes, causing various symptoms related to low blood counts. Patients may experience weakness, weight loss, and night sweats. The disease can progress slowly, but the symptoms can significantly impact daily life.

Indolent Systemic Mastocytosis – Indolent Systemic Mastocytosis is a condition characterized by an abnormal accumulation of mast cells in various tissues, including the skin, bone marrow, and internal organs. This accumulation can lead to symptoms such as skin rashes, itching, and abdominal discomfort. The disease is termed “indolent” because it progresses slowly and often has a stable course. Patients may experience episodes of flushing, low blood pressure, and gastrointestinal issues. Despite the chronic nature of the condition, it typically does not lead to organ damage.
