简要总结
Skin toxicities are a major complication to cancer therapies. They can be painful and limit the amount of drug that can be received by cancer patients, preventing the patients from receiving optimal doses of drug. One such cutaneous toxicity, hand-foot skin reaction (HFSR), is caused by next generation targeted agents that are in routine use for the treatment of kidney and liver cancer. HFSR is characterized by swelling, redness, and pain of the palms and soles, in addition to the development of painful or thickened callus-like plaques with fissures in areas of friction and pressure. The investigators have identified a topical skin-directed therapy, 1% topical sildenafil cream, that the investigators believe will be useful in preventing and ameliorating this painful, skin side effect associated with the targeted agents sorafenib and sunitinib. This project proposal aims to conduct an open-label pilot study to assess whether pre-medication with this cream can be an effective way of preventing or decreasing the severity of hand-foot skin reaction, improving their quality of life on therapy and enabling the patients to receive optimal amounts of their anti-cancer drug.
详细描述
The purpose of this study is to evaluate the effect of topical sildenafil as a pre-treatment regimen for HFSR in patients naïve to anti-cancer therapy who will be initiated on treatment with sorafenib or sunitinib. The study endpoint will be the onset and calculated incidence of any grade of HFSR. Skin toxicity grading per National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03 will be performed by the investigator at each visit (every 2 weeks) until the end of the study (12 weeks total).
This study aims to:
- Determine whether HFSR can be prevented with topical sildenafil as pre-treatment.
- Determine whether topical sildenafil can reduce the incidence of HFSR in patients treated with sorafenib or sunitinib.
- Determine whether topical sildenafil can delay the onset of HFSR.
- Determine whether topical sildenafil can reduce the severity of skin lesions if HFSR does occur.
Patient Eligibility:
The target population for this study is patients with clinically-diagnosed cancer who will be treated with sorafenib or sunitinib. A total of 20 subjects will be needed for this trial. There is no placebo group for this study. Subjects must meet all of the inclusion criteria and none of the exclusion criteria to be registered to the study.

入选标准
- •Patients with a clinical diagnosis of cancer that are within ± 3 days of initiating treatment with sorafenib or sunitinib. Patients treated with a combination regimen that includes sorafenib or sunitinib are eligible.
- •Patients must be age ≥ 18 years.
- •Patients must exhibit an ECOG performance status of 0 to
- •Females of child-bearing potential (FOCBP) and males must agree to use adequate contraception (e.g., hormonal contraceptives such as birth control pills, patch, intrauterine device; barrier contraception such as male/female condoms, diaphragm; male partner with vasectomy; abstinence) prior to study entry, for the duration of study participation, and for 30 days following completion of therapy. Should a female patient become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. NOTE: A FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: has not undergone a hysterectomy or bilateral oophorectomy or has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months).
- •FOCBP must have a negative urine or serum pregnancy test within 7 days prior to registration on study.
- •Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration in the study.
排除标准
- •Patients with a prior diagnosis of hand-foot skin reaction are not eligible.
- •Patients who have had other chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier are not eligible.
- •Patients who have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to sildenafil or phosphodiesterase-5 (PDE5) inhibitors such as vardenafil (Levitra) and tadalafil (Cialis) are not eligible.
- •Patients may not be receiving any other investigational agents. Note: it is acceptable to be on combination therapy including either sorafenib and/or sunitinib.
- •Patients must not be using topical steroids (e.g., hydrocortisone). Topical over-the-counter antibiotics (e.g., Neosporin) and skin protectants (e.g., Vaseline, Aquaphor) for local skin fissures on hands and feet are allowed. Patients are allowed to use topical medications on other body parts, besides the hands and feet, but must use qtips or gloves for application.
- •Patients taking nitrates (e.g., nitroglycerin, isosorbide mononitrate, isosorbide dinitrate) and/or alpha blockers (e.g., tamsulosin, prazosin, afluzosin, silodosin) are not eligible.
- •Patients taking Viagra must have a 1 day washout period prior to treatment. Note: patients must agree to discontinue Viagra while on study treatment.
- •Female patients who are pregnant or nursing are not eligible.
- •Patients must not have any condition or situation which, in the investigator's opinion, puts the patient at significant risk, could confound the study results, or may interfere significantly with the patient's participation in the study.
- •Patients who are unable to communicate or cooperate with the investigator due to language problems, poor mental development, or impaired cerebral function are not eligible.
