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

November 14, 2012 updated by: Infinity Pharmaceuticals, Inc.

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

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]).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • ≥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.

Exclusion Criteria:

  • 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.
