A Study to Evaluate INCA033989 Administered as a Monotherapy or in Combination With Ruxolitinib in Participants With Myeloproliferative Neoplasms
What this study is about
This study is being conducted to evaluate the safety, tolerability, dose-limiting toxicity (DLT) and determine the maximum tolerated dose (MTD) and/or recommended dose(s) for expansion (RDE) of INCA033989 administered as a treatment given alone or in Combination With Ruxolitinib in participants with myeloproliferative neoplasms.

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
- Life expectancy \> 6 months.
- Willingness to undergo a pretreatment and regular on-study BM biopsies and aspirates (as appropriate to disease).
- Existing documentation from a qualified local laboratory of CALR exon-9 mutation.
- Participants with MF or ET as defined in the protocol.
Exclusion criteria
- Presence of any hematological malignancy other than ET, PMF, or post-ET MF.
- Prior history of major bleeding, or thrombosis within the last 3 months prior to study enrollment.
- Participants with laboratory values exceeding the protocol defined thresholds.
- Has undergone any prior allogenic or autologous stem-cell transplantation or such transplantation is planned.
- Active invasive malignancy over the previous 2 years.
- History of clinically significant or uncontrolled cardiac disease.
- Active or chronic HBV or active HCV or known history of HIV.
- Any prior chemotherapy, immunomodulatory drug therapy, immunosuppressive therapy, biological therapy, endocrine therapy, targeted therapy, antibody, or hypomethylating agent used to treat the participant's disease, with the exception of ruxolitinib for TGBs only, within 5 half-lives or 28 days (whichever is shorter) before the first dose of study treatment.
- Participants undergoing treatment with G-CSF, GM-CSF, or TPO-R agonists at any time within 4 weeks before the first dose of study treatment. Other protocol-defined Inclusion/Exclusion Criteria may apply.

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.
