Authorised Therapeutic exploratory (Phase II) Myeloproliferative neoplasms (MPNs), myelofibrosis, essential thrombocythemia, and polycythemia vera

A Study of LY2784544 in patients with blood cancer

EU CTIS ID: 2024-514254-69-00

What this study is testing

The primary objective of this study is to assess the activity of LY2784544 therapy administered once daily, as measured by objective response rate, in patients with the myeloproliferative neoplasms (MPNs), polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF).

  • Therapeutic exploratory (Phase II)

A plain-language read of the study's public EU CTIS listing. The study team confirms the details.

Who can take part

You may be able to join if

  • Have a diagnosis of polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF) as defined by the World Health Organization (WHO) diagnostic criteria for myeloproliferative neoplasms
  • Have discontinued all previous approved therapies for MPNs, including any chemotherapy, immunomodulating therapy (for example, thalidomide, interferon-alpha), immunosuppressive therapy (for example, corticosteroids >10 mg/day prednisone or equivalent), radiotherapy, and erythropoietin, thrombopoietin, or granulocyte colony stimulating factor for at least 14 days and recovered from the acute effects of therapy. Hydroxyurea used to control blood cell counts is permitted at study entry if the subject has been maintained on a stable dose for at least 4 weeks. Low-dose acetylsalicylic acid (aspirin 80 or 100mg) is permitted as well.
  • Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures.
  • Males and females with reproductive potential must agree to use medically approved contraceptive precautions during the study and for 3 months following the last dose of study drug.
  • Females with child-bearing potential must have had a negative urine pregnancy test £7 days before the first dose of study drug and must also not be breastfeeding.
  • Are able to swallow capsules.

You likely can't join if

  • Are currently enrolled in, or discontinued within the last 14 days from a clinical trial involving an investigational product or non-approved use of a drug or device, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study.
  • Have a corrected QT (QTc) interval >470 msec using Bazett's formula.
  • Have serious preexisting medical conditions that, in the opinion of the investigator would preclude participation in the study (for example a gastrointestinal disorder causing clinically significant symptoms such as nausea, vomiting, and diarrhea, or malabsorption syndrome).
  • Are currently being treated with agents that are metabolized by CYP3A4 with a narrow therapeutic margin (for example, alfentanil, cyclosporine, diergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, and tacrolimus) or CYP2B6 (for example, cyclophosphamide, ifosfamide, tamoxifen, efavirenz, propofol, methadone, and bupropion).
  • Are currently being treated with warfarin or 1 of its derivatives which is known to alter levels of protein C or protein S. An exception to this criterion will be allowed for patients with a prior history of Budd-Chiari Syndrome who are being treated with warfarin or 1 of its derivatives.
  • Have received a hematopoietic stem cell transplant.
