Description

Summary

Chemotherapy, radiation therapy, and surgery are standard treatments for basal cell carcinoma at most institutions. The purpose of this study is to determine whether adding vismodegib to radiation (chemoradiotherapy) is safe and tolerable. The purpose of this study is to assess the safety and tolerability of combined radiation therapy and vismodegib. This combination may increase the chances of the tumors being destroyed or unable to spread to other parts of the body in people with locally advanced basal cell carcinoma of the head and neck.

Official Title

A Phase II Study of Radiation Therapy and Vismodegib, for the Treatment of Locally Advanced Basal Cell Carcinoma of the Head and Neck

Details

This is a single arm, multi-center Phase II clinical trial to assess the safety and demonstrate the efficacy of a combined modality approach using radiation therapy after induction and concurrently with systemic administration of vismodegib, which may increase the rates of complete response and sustained local control in patients with locally advanced BCC

Open to people ages 18 years and up

  1. Patients with locally advanced BCC of the head and neck, consisting of at least one histologically or cytologically confirmed lesion greater than or equal to 20 mm in longest diameter that is considered to be inoperable or to have a medical contraindication to surgery, in the opinion of a Mohs dermatologic surgeon, head and neck surgeon, or plastic surgeon. Locally advanced disease is considered to include involved lymph nodes of the neck. A patient with regionally involved lymph nodes in the neck is considered eligible. The patient should be considered a candidate for radiotherapy and should not have medical contraindications to receipt of radiation therapy.

If a patient has distant metastatic spread of BCC (e.g., spread to distant areas outside the regional lymph nodes, clearly non contiguous areas of bone involvement, or distant metastasis to lung, brain, or other visceral organs), the patient should be considered as having distant metastasis and is not eligible.

Note: All lesions that the investigator proposes to follow as target lesions during the course of the study must have previously been histologically confirmed as BCC.

Acceptable contraindications to surgery include:

  • BCC that has recurred in the same location after two or more surgical procedures and successful curative resection is deemed unlikely
  • Complete surgical resection is not possible or is deemed excessively morbid (e.g.invasion into cranial nerves or skull base, proximity to brain, spinal canal, or orbit)
  • Anticipated substantial morbidity and/or major deformity from surgery (e.g.removal of a major facial structure, such as nose, ear, eyelid, eye, or jaw; or requirement for upper limb amputation)
  • Medical contraindication to surgery
  • Patient refusal of surgery due to anticipated morbidity
  • Other conditions considered to be contraindicating must be discussed with Data Coordinator before enrolling the patient.
  • Prior radiation therapy is acceptable but there cannot be major overlap of the previously irradiated tissues with the new radiation treatment volumes anticipated to be delivered for the purposes of this protocol, in such a way that curative intent with radiation cannot be met. Furthermore, the total dose from all radiation delivered and expected to be delivered should not exceed the suggested dose constraints given for normal structures.
  • Zubrod Performance Status 0-2
  • Age of greater than or equal to 18 years
  • Adequate bone marrow and organ function defined as follows:

Adequate bone marrow function:

leukocytes: > 3,000/mcL absolute neutrophil count: greater than or equal to 1000 cells/mm3 platelets: greater than or equal to 75,000 cells/mm3 hemoglobin: greater than or equal to 8.5 g/dl (recommended cutoff subject to judgment of medical oncologist), but cannot be transfusion dependent

Adequate hepatic function:

total bilirubin: less than or equal to 1.5x institutional ULN or within 3x the ULN for patients with Gilbert disease AST(SGOT): < 3 X institutional upper limit of normal

ALT(SGPT): < 3 X institutional upper limit of normal

Adequate renal function:

creatinine: within normal institutional limits OR creatinine clearance: > 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal

  1. Agreement not to donate blood or blood products during the study and for 7 months after discontinuation of vismodegib; for male patients, agreement not to donate sperm during the study and for 7 months after discontinuation of vismodegib.
  2. For male patients, agreement not to donate sperm during the study and for 3 months after the final dose of vismodegib. Male patients must use condoms at all times, even after a vasectomy, during sexual intercourse with pregnant partners or female partners of reproductive potential during treatment with vismodegib. Vismodegib is present in semen. It is not known if the amount of vismodegib in semen can cause embryo-fetal harm.
  3. Verify the pregnancy status of females of reproductive potential within 7 days prior to initiating vismodegib. For women of childbearing potential, a negative pregnancy test within 7 days prior to commencement of dosing is required. Women of reproductive potential are required to use two forms of acceptable contraception (including one acceptable barrier method with spermicide) during therapy and for 7 months after completing therapy. Acceptable forms of primary contraception include the following:Combination hormonal contraceptives, subcutaneous hormonal implant, hormonal patch,hormonal contraceptives (levonorgestre-releasing intrauterine system,medroxyprogesterone acetate depot), tubal sterilization, vasectomy, and intrauterine device (IUD). Acceptable forms of barrier contraception include the following: any male condom (with spermicide) or diaphragm (with spermicide).

You CAN'T join if...

  1. Patients with distant metastasis (e.g. spread to distant areas outside the regional lymph nodes, clearly non contiguous areas of bone involvement, or distant metastasis to lung, brain, liver or other visceral organs) are ineligible.
  2. Patients with nevoid BCC syndrome (Gorlin syndrome) should not enroll in this study.
  3. A patient with a known other malignancy is eligible if there is a negligible risk for disease progression or death within one year, there is no active ongoing treatment for this malignancy, and the malignancy and/or any anticipated future treatments would not interfere with protocol-mandated evaluations at 1 year.
  4. Prior vismodegib or other antagonists of the Hh pathway;
  5. Concurrent non-protocol-specified anti-tumor therapy (e.g., chemotherapy, other targeted therapy, topical therapy such as 5-Fluorouracil or imiquimod, radiation therapy, surgery, or photodynamic therapy.
  6. For patients with multiple cutaneous BCCs at baseline that are not designated by the investigator as target lesions, treatment of these non-target BCCs with surgery may be permitted but must be discussed with Data Coordinator prior to any surgical procedure.
  7. Recent (within 4 weeks of Registration), current, or planned participation in another experimental drug study.
  8. Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields in such a way that curative intent with radiation cannot be met

  17. . Life expectancy of <1 year
  18. . Patients with widespread superficial multifocal BCC who are considered unresectable due to breadth of involvement and do not have a single definable area of disease amenable to radiation therapy targeting.

Note: If an area including one or more lesions is definable for radiation therapy targeting, the patient may be eligible for treatment on study using the designated target lesion(s) identified by the investigator.

  1. . Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with study requirements;
