A Phase 2, Open-Label, Single-Arm, Multicenter Study Evaluating the Safety and Antitumor Activity of IPI-504, A Novel Small Molecule Inhibitor of Heat Shock Protein 90 (HSP90), in Patients With Metastatic Melanoma


To evaluate the antitumor activity of IPI-504 in patients with metastatic melanoma and to
assessment of antitumor activity is the 6-month progression-free rate.


Inclusion Criteria:



- Histologically confirmed, unresectable, Stage IV or recurrent melanoma, including
mucosal melanoma (based on American Joint Committee on Cancer [AJCC] staging [Balch,
2001], see Appendix A).

- Prior therapy with chemotherapy and/or immunotherapy for melanoma is allowed provided
that therapy ended prior to study entry and all treatment-related toxicities have
resolved to NCI CTCAE Grade ≤ 1 or patient's baseline;

- Measurable disease (based on RECIST [Therasse, 2000]) defined as at least one lesion
that can be accurately measured in at least one dimension (longest diameter to be
recorded) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT scan;

- Have melanoma that can be biopsied once prior to treatment (all patients), and a
second time during treatment with IPI504 (stage 2 patients);

- Willingness for tumor biopsy at screening (all patients) and once during treatment
(stage 2 patients only);

- Males and females of at least 18 years of age at the time of study entry;

- Female patients must be of non child-bearing potential (defined as being >1 year
post-menopausal) or using effective contraception, eg, use of oral contraceptives
with an additional barrier method (since the study drug may impair the effectiveness
of oral contraceptives), double barrier methods (diaphragm with spermicidal gel or
condoms with contraceptive foam), Depo-Provera, partner vasectomy, or total
abstinence, from the time the informed consent is signed through 30 days after the
last dose of IPI-504. Male patients must be surgically sterile or use a
double-barrier method of contraception (condom with spermicide) from the time of the
initiation of IPI-504 through 30 days after the last dose of IPI-504;

- Eastern Cooperative Oncology Group performance status of 0 to 2;

- Life expectancy of at least 16 weeks;

- White blood cell (WBC) count ≥ 3,000/mm3, absolute neutrophil count (ANC) ≥
1,500/mm3, platelet count ≥ 100,000/mm3; Prothrombin time or international normalized
ratio within normal range (unless a patient is receiving anticoagulation therapy), or
PTT within normal range;

- Serum creatinine ≤ 1.5 × ULN and creatinine clearance ≥ 50 mL/min (by Cockroft-Gault
method);

- Total bilirubin ≤ 1.5 × ULN [unless due to Gilbert's syndrome (unconjugated
hyperbilirubinemia) in which case the total bilirubin should be ≤ 3.5 mg/dL], AST and
ALT ≤ 2.5 × ULN, hepatic alkaline phosphatase ≤ 2.5× ULN;

- LDH ≤ 1.5 × ULN;

- Patients who have had prior radiation therapy are eligible provided that therapy was
palliative in nature, not in the area where the tumor will be biopsied, at least one
measurable lesion outside the radiation field, and all radiation-related toxicities
have resolved to NCI CTCAE Grade ≤ 1 or patient's baseline;

- Patients who had recovered from prior major surgery are eligible if all surgical
wounds have healed;

- Written informed consent and HIPAA authorization obtained from the patient prior to
receipt of any study medication or beginning study procedures.

Exclusion Criteria:

- Received an investigational agent or therapy with any other kinase inhibitor within 2
weeks prior to study entry or any other antitumor therapy, such as cytostatic and/or
cytotoxic drugs, hormonal therapy, radiation therapy, immunotherapy, or any
biological response modifiers within 4 weeks prior to study entry;

- Previous treatment with 17-AAG, 17-dimethylaminoethylamino-17-demethoxygel-danamycin
(17-DMAG), or other known Hsp90 inhibitor;

- Any concurrent chemotherapy, radiotherapy, immunotherapy, biologic or hormonal
therapy for treatment of cancer;

- Current or planned participation (from the day of study entry through 30 days after
the last dose of IPI-504) in a research protocol in which an investigational agent or
therapy may be administered;

- Initiation or discontinuation of concurrent medication that alters CYP3A activity
(see Appendix C) within 2 weeks prior to treatment with IPI-504. Patients who are on
a stable dose of drugs known to alter CYP3A activity for > 2 weeks are eligible to
enroll;

- Presence of active infection or systemic use of antimicrobials within 72 hours prior
to treatment with IPI-504;

- Known brain metastases or primary brain tumors. Patients with ≤ 2 lesions are
eligible provided:

- Treated with surgery or stereotactic radiosurgery

- The lesions are < 3 cm in size and have been stable for 2 months (by CT/MRI)

- The patient has been off steroids for at least 1 week prior to dosing and:

- The patient is allowed to have had whole brain radiation if performed in
conjunction with surgery/stereotactic radiotherapy and the last dose of
radiation occurred at least 2 months prior to dosing with IPI504.

- Significant comorbid condition or disease which in the judgment of the Investigator
would place the patient at undue risk or interfere with the study (eg, cardiac
disease such as acute coronary syndrome or unstable angina within 6 months,
uncontrolled hypertension, cirrhotic liver disease, cerebrovascular accident, or
other conditions);

- History of prior malignancies within the past 5 years other than non-melanomatous
skin cancers that have been controlled, carcinoma in situ of the cervix, T1a or b
prostate cancer noted incidentally during a transurethral resection of prostate
(TURP) with prostate-specific antigen values within normal limits since TURP, or
superficial bladder cancer;

- Women who are pregnant or lactating;

- Sinus bradycardia (resting heart rate < 50 beats/min) secondary to intrinsic
conduction system disease; Patients with sinus bradycardia secondary to pharmacologic
treatment may enroll if withdrawal of the treatment results in normalization of the
resting heart rate to within normal limits;

- Screening QTc > 450 msec in males; QTc > 470 msec in females, or previous history of
QTc prolongation while taking other medications; or

- Active or recent history (within 3 months) of keratitis or keratoconjunctivitis,
confirmed by ophthalmology or optometry exam.
