Randomized RT +/- Lapatinib for Advanced Solid Tumor Cancer Patients Receiving Radiation Therapy for Metastatic Disease

Stopped early · Early Phase 1

Conditions studied: Epithelial Cancer

In brief

Lapatinib will prevent radiation-induced increase in Transforming Growth Factor alpha (TGFα), an important growth factor in cancer cell recovery after ionizing irradiation.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• History of stage IV epithelial-derived cancer requiring palliative radiation. Patients with sarcoma, lymphoma, myeloma or neuroendocrin cancers are not eligible.
• Evidence of metastatic disease
• Recommendation by patient's radiation oncologist to receive palliative external beam radiation for metastases -- minimum fraction size of 3 Gy.
• Age 18 years or older
• Patients may be undergoing concurrent therapy with GNRH agonists or combined androgen blockade or anti-estrogen hormonal therapy for breast cancer, as these are standard care for advanced prostate and some breast cancers respectively.
• Ability to understand and the willingness to sign a written informed consent document

You may not qualify if…

• Any contraindication to lapatinib treatment.
• Prior radiation therapy within 30 days of the start of the planned course of treatment.
• Prior cytotoxic chemotherapy within 4-2 weeks of planned first dose of radiation. Persistent grade 2 or greater non-hematologic toxicity (other than neuropathy) from cytotoxic chemotherapy regardless of interval since last dose. Persistent grade 3 or greater hematologic toxicity (other than lymphopenia) reglardless of interval since last dose.
• Prior administration of an ERBB1 or ERK1/2 inhibitor within 30 days of the start of the planned course of treatment.
• Patients with a medical necessity to continue active therapy with CYP3A4 strong inhibitors or inducers. The concomitant use of strong CYP3A4 inhibitors should be avoided (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole, aprepitant). Grapefruit may also increase plasma concentrations of lapatinib and should be avoided. Once the strong inhibitor or inducer is discontinued, a washout period of approximately 1 week should be allowed before the lapatinib administration. If a patient is unable to discontinue these medications, they are not eligible for enrollment.
• Concurrent administration of any other investigational agents.
• Uncontrolled concurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, active hepatic or biliary disease with a Child-Pugh class of B or C, or psychiatric illness/social situations that would limit compliance with study requirements or that would interfere with accomplishing the study objectives.
• Pregnant or nursing. Women of childbearing potential must have a negative pregnancy test performed within 7 days prior to the start of treatment. Women of childbearing potential and men must agree to use a medically accepted form of birth control for the duration of study participation. Men must agree to use a medically accepted form of birth control for 4 months following completion of study treatment.
