Trametinib in Treating Patients With Epithelioid Hemangioendothelioma That is Metastatic, Locally Advanced, or Cannot Be Removed by Surgery

Status:
Active, not recruiting
Trial end date:
2023-12-31
Target enrollment:
0
Participant gender:
All
Summary
This phase II trial studies how well trametinib works in treating patients with epithelioid hemangioendothelioma that has spread to other places in the body (metastatic), nearby tissue or lymph nodes (locally advanced), or cannot be removed by surgery (unresectable). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Criteria
Inclusion Criteria:

- Patients must have measurable disease, defined as at least one lesion that can be
accurately measured in at least one dimension (longest diameter to be recorded for
non-nodal lesions and short axis for nodal lesions) as >= 20 mm (>= 2 cm) with
conventional techniques or as >= 10 mm (>= 1 cm) with spiral computed tomography (CT)
scan, magnetic resonance imaging (MRI), or calipers by clinical exam; baseline imaging
must be obtained within 30 days of day 1 of study

- Patients must have histologically confirmed epithelioid hemangioendothelioma which is
metastatic or locally advanced (unresectable), and tumor tissue (paraffin-embedded
tissue block or tumor tissue on unstained glass slides) available for fusion
fluorescence in situ hybridization (FISH) analysis at Cleveland Clinic; patient tumor
tissue stored in pathology archives may be used for fusion FISH; a new biopsy is not
mandatory

- Patients must have evidence of disease progression per RECIST 1.1 prior to enrollment
or have evidence of cancer-related pain requiring symptom management with narcotic
analgesics

epithelioid hemangioendothelioma (EHE), patients previously untreated or treated with

used to be eligible

significant gastrointestinal abnormalities that may alter absorption such as
malabsorption syndrome or major resection of the stomach or small bowel

weeks of patient registration)

- Platelets >= 75 x 10^9/L (within 2 weeks of patient registration)

- Albumin >= 2.5 g/dL (within 2 weeks of patient registration)

- Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (within 2 weeks of
patient registration); NOTE: patients with elevated bilirubin secondary to Gilbert's
disease are eligible to participate in the study

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x
institutional ULN (within 2 weeks of patient registration)

- Serum creatinine =< 1.5 mg/dL OR calculated creatinine clearance (Cockcroft-Gault
formula) >= 50 mL/min OR 24-hour urine creatinine clearance >= 50 mL/min (within 2
weeks of patient registration)

- Left ventricular ejection fraction (LVEF) >= institutional lower limit of normal (LLN)
by echocardiogram (ECHO) or multigated acquisition scan (MUGA) (within 30 days of
registration)

- Trametinib can cause fetal harm when administered to a pregnant woman; women of
child-bearing potential and men must agree to use adequate contraception (hormonal or
barrier method of birth control; abstinence) prior to study entry, during the study
participation, and for four months after the last dose of the drug; women of
child-bearing potential must have a negative serum pregnancy test within 14 days prior
to enrollment and agree to use effective contraception throughout the treatment period
and for 4 months after the last dose of study treatment; should a woman become
pregnant or suspect she is pregnant while she or her partner is participating in this
study, she should inform her treating physician immediately

- Human immunodeficiency virus (HIV)-patients positive for human immunodeficiency virus
(HIV) are NOT excluded from this study, however HIV-positive patients must meet the
following criteria:

- A stable regimen of highly active anti-retroviral therapy (HAART)

- No requirement for concurrent antibiotics or antifungal agents for the prevention
of opportunistic infections

- A CD4 count above 250 cells/mcL and an undetectable HIV viral load on standard
polymerase chain reaction (PCR)-based test

Exclusion Criteria:

- Prior systemic therapy with a MEK inhibitor

- History of another malignancy

- Exception: patients who have been disease-free for 3 years or patients with a
history of completely resected non-melanoma skin cancer and/or patients with
indolent secondary malignancies, are eligible; consult the Cancer Therapy
Evaluation Program (CTEP) medical monitor if unsure whether second malignancies
meet the requirements specified above

- History of interstitial lung disease or pneumonitis requiring supplemental oxygen or
treatment with oral or intravenously administered corticosteroids

- Any major surgery, extensive radiotherapy, chemotherapy with delayed toxicity (e.g.
doxorubicin), biologic therapy, or immunotherapy within 21 days prior to enrollment
and/or daily or weekly chemotherapy (e.g. sunitinib, sorafenib and pazopanib) without
the potential for delayed toxicity within 14 days prior to enrollment

- Use of other investigational drugs within 28 days (or five half-lives, whichever is
shorter; with a minimum of 14 days from the last dose) preceding the first dose of
trametinib and during the study

- Symptomatic or untreated leptomeningeal or brain metastases or spinal cord compression

- Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs
chemically related to trametinib, or excipients or to dimethyl sulfoxide (DMSO)

- Current use of a prohibited medication; the following medications or non-drug
therapies are prohibited:

- Other anti-cancer therapy while on study treatment; (note: megestrol [Megace] if
used as an appetite stimulant is allowed)

- Concurrent treatment with bisphosphonates is permitted; however, treatment must
be initiated prior to the first dose of study therapy; prophylactic use of
bisphosphonates in patients without bone disease is not permitted, except for the
treatment of osteoporosis

- Because the composition, pharmacokinetics (PK), and metabolism of many herbal
supplements are unknown, the concurrent use of all herbal supplements is
prohibited during the study (including, but not limited to, St. John's wort,
kava, ephedra [ma huang], ginkgo biloba, dehydroepiandrosterone [DHEA], yohimbe,
saw palmetto, or ginseng)

- Trametinib was embryotoxic and abortifacient in rabbits at doses greater than or equal
to those resulting in exposures approximately 0.3 times the human exposure at the
recommended clinical dose. Therefore, the study drug must not be administered to
pregnant women or nursing mothers; women of childbearing potential should be advised
to avoid pregnancy and use effective methods of contraception; men with a female
partner of childbearing potential must have either had a prior vasectomy or agree to
use effective contraception; if a female patient or a female partner of a patient
becomes pregnant while the patient receives trametinib, the potential hazard to the
fetus should be explained to the patient and partner (as applicable)
