Pilot Study for the Treatment of Steroid-Refractory Sclerodermatous Chronic Graft-Versus-Host Disease (GVHD) With GDC-0449 (GDC-0449)

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.

Inclusion Criteria:

- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

- Life expectancy of greater than 12 months

- Leukocytes >= 3,000/mcL

- Absolute neutrophil count >= 1,500/mcL

- Platelets >= 50,000/mcL

- Total bilirubin within normal institutional limits

- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase
[SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT])
=< 2.5 x institutional upper limit of normal

- Creatinine =< 1.5 mg/dl OR creatinine clearance >= 55 mL/min using the Cockcroft-Gault
equation for patients with creatinine levels above 1.5 mg/dl

- Patients with chronic GVHD diagnosed within 3 years after hematopoietic stem cell
transplant (HSCT) for any disease, with any graft, and any conditioning regimen with
at least one manifestation secondary to fibrosis, including: sclerodermatous skin
changes, dry mouth, dry eye, esophageal strictures, or vaginal GVHD

- 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 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:

- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study or those who have not
recovered from adverse events due to agents administered more than 4 weeks earlier

- Patients who are receiving any other investigational agents

- Patients with known brain metastases should be excluded from this clinical trial

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to GDC-0449

- Patients receiving any medications or substances that are strong inducers/inhibitors
or substrates of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4)/5,
cytochrome P450, family 2, subfamily C, polypeptide 9 (CYP2C9), CYP2C8, or CYP2C19 are
ineligible; as part of the enrollment/informed consent procedures, the patient will be
counseled on the risk of interactions with other agents, and what to do if new
medications need to be prescribed or if the patient is considering a new
over-the-counter medicine or herbal product

- Patients with malabsorption syndrome or other condition that would interfere with
intestinal absorption; patients must be able to swallow capsules

- Patients with clinically important history of liver disease, including viral or other
hepatitis or cirrhosis are ineligible

- Patients with uncontrolled hypocalcemia, hypomagnesemia, hyponatremia or hypokalemia
defined as less than the lower limit of normal for the institution, despite adequate
electrolyte supplementation are excluded from this study

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements
