Vismodegib in Treating Patients With Steroid-Refractory Chronic Graft-Versus-Host Disease

This pilot clinical trial studies how well vismodegib works in treating patients with chronic graft-versus-host disease that did not respond to previous steroid treatment. Chronic graft-versus-host disease can cause a build-up of scar tissue under the skin and lead to symptoms such as sclerodermatous skin changes, dry mouth, dry eye, narrowing of the esophagus, or vaginal graft-versus-host disease. Vismodegib may work against the build-up of scar tissue and be a better treatment for chronic graft-versus-host disease caused by a hematopoietic stem cell transplant.

PRIMARY OBJECTIVES:

I. To determine the clinical effects of GDC-0449 (vismodegib), in steroid-refractory chronic graft-versus-host disease (GVHD).

SECONDARY OBJECTIVES:

I. To determine the safety of GDC-0449 in patients with steroid-refractory GVHD.

II. To determine the change in National Institutes of Health (NIH) Consensus Criteria (CC) global score of chronic GVHD at 6 and 12 months from baseline.

III. To determine one-year non relapse mortality (NRM) and one-year relapse rate.

IV. To determine one-year failure free survival (FFS) and one-year overall survival (OS).

V. To determine baseline clinical characteristics that may be associated with decreased FFS.

OUTLINE:

Patients receive vismodegib orally (PO) daily, every other day, every three days, or twice weekly for 6-12 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 6 months.

* Failure to respond to corticosteroids, defined as:

  * Progression of chronic GVHD despite optimal first line therapy (\> 0.5 mg/kg/day of prednisone dose equivalent (PDE) for two weeks) or
  * No improvement after 4-8 weeks of sustained therapy; sustained therapy should include 2 weeks of \> 0.5 mg/kg/day of PDE or
  * Inability to taper steroid dosage to less than 0.5 mg/kg/day of PDE without worsening of chronic GVHD or
  * Need for second or third line therapy beyond corticosteroids and calcineurin inhibitors or sirolimus, irrespective of other criteria
* Women of child-bearing potential and men must use two forms of contraception (i.e., barrier contraception and one other method of contraception) at least 4 weeks prior to study entry, for the duration of study participation, and for at least 24 months post-treatment; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

  * Women of childbearing potential are required to have a negative serum pregnancy test (with a sensitivity of at least 25 milli-international unit (mIU)/mL) within 7 days prior to the first dose of GDC-0449 (serum or urine); a pregnancy test (serum or urine) will be administered every 4 weeks if their menstrual cycles are regular or every 2 weeks if their cycles are irregular while on study within the 24-hour period prior to the administration of GDC-0449; a positive urine test must be confirmed by a serum pregnancy test; prior to dispensing GDC-0449, the investigator must confirm and document the patient's use of two contraceptive methods, dates of negative pregnancy test, and confirm the patient's understanding of GDC-0449 cause serious or life-threatening birth defects; patients must continue highly effective contraception during therapy and for 24 months after the last dose of GDC-0449
  * Women of childbearing potential are defined as follows:

    * Patients with regular menses
    * Patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding
    * Women who have had a tubal ligation
  * Women are considered not to be of childbearing potential for the following reasons:

    * The patient has undergone hysterectomy and/or bilateral oophorectomy
    * The patient is post-menopausal defined by amenorrhea for at least 12 months in a woman \> 45 years old
  * Male patients should use condoms with spermicide, even after a vasectomy, during sexual intercourse with female partners while being treated with GDC-0449 and for 3 months after the last dose to avoid exposing an embryo or fetus to GDC-0449
* Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are eligible provided that they meet the following criteria in addition to the other protocol criteria:

  * Cancer as the only acquired immunodeficiency syndrome (AIDS)-defining condition
  * Cluster of differentiation (CD)4 cell count \>= 250
  * Treatment sensitive HIV and prospects for long term survival on the basis of HIV disease alone
  * Willing to take anti-HIV therapy that will have minimal potential for pharmacokinetic interactions with GDC-0449

Exclusion Criteria:
