A Phase 2 Study With IPI-926 in Patients With Myelofibrosis

Completed · Phase 2

Conditions studied: Primary Myelofibrosis, Fibrosis, Bone Marrow

In brief

The purpose of this study is to determine the safety and efficacy of IPI-926 in patients with myelofibrosis (MF) (primary myelofibrosis \[PMF\], post-polycythemia vera myelofibrosis \[post-PV MF\], or post-essential thrombocythemia myelofibrosis \[post-ET MF\]).

Who can join

Age: 18 and older, up to 90. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• ≥18 years of age at the time of signing the ICF.
• Voluntarily sign an ICF.
• Pathologically confirmed PMF or post ET/PV MF as per the WHO diagnostic criteria (note that it must include at least Grade 1 marrow fibrosis, see Appendix 3) with intermediate-1, intermediate -2, or high risk disease according to the IWG prognostic scoring system (see Appendix 4). If patients have low risk disease, then they must have symptomatic splenomegaly that is ≥ 10 cm below left costal margin by physical exam.
• ECOG performance of 0-2.
• Life expectancy of at least 3 months.
• Recovery to Grade 1 or baseline of any toxicities due to prior systemic treatments, excluding alopecia.
• If a woman, be of non-child bearing potential or, for women of child-bearing potential (WCBP) (defined as a sexually mature woman who has not undergone surgical sterilization or who has not been naturally post-menopausal for at least 24 consecutive months for women ≤55 years; for women >55 years 12 consecutive months), must have a negative serum or urine pregnancy test result within 2 weeks of first dose of study drug.
• All WCBP and all sexually active male patients must agree to use adequate methods of birth control throughout the study. Adequate methods of contraception include use of oral contraceptives with an additional barrier method, double barrier methods (diaphragm with spermicidal gel or condoms with contraceptive foam), Depo-Provera, partner vasectomy, and total abstinence.
• Ability to adhere to the study visit schedule and all protocol requirements.

You may not qualify if…

• Prior treatment with any inhibitor of the hedgehog pathway (e.g. GDC-0449).
• Received any treatment for myelofibrosis within 2 weeks of study entry.
• Other invasive malignancies diagnosed within the last 3 years, except non-melanoma skin cancer and localized cured prostate and cervical cancer.
• Inadequate hepatic function defined by:
• Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2.5 x upper limit of normal (ULN).
• Direct bilirubin >1.5 x ULN.
• Cirrhotic liver disease, ongoing alcohol abuse, or known chronic active or acute hepatitis.
• Inadequate renal function defined by serum creatinine >2 x ULN.
• History of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia requiring medication or mechanical control within the last 6 months.
• Presence of active infection or systemic use of antibiotics within 72 hours of treatment.
• Significant co-morbid condition or disease, which in the judgment of the Investigator, would place the patient at undue risk or interfere with the study.
• Known human immunodeficiency virus (HIV) positivity.
• Known hypersensitivity to IPI-926, or any of the excipients in IPI-926 capsules.
• Pregnant or lactating women.
