Treatment Duration Increment and Pharmacodynamic Study of CX-4945 in Patients With Basal Cell Carcinoma (BCC)
United States25 participantsStarted 2019-04-16
Plain-language summary
This study is to determine the recommended phase II dose (RP2D) and schedule of CX-4945 when administered orally twice daily for 28 consecutive days, in a 4-week (28 days) cycle, in patients with locally advanced or metastatic basal cell carcinoma (BCC). The safety and tolerability of CX-4945, preliminary evidence of antitumor effect, and the effect of CX-4945 treatment on the Hh signaling pathway will also be evaluated in this study.

Inclusion criteria
. Signed, written IRB-approved informed consent.
. Men and women age ≥ 18 years
. ECOG Performance status 0 or 1
. For patients with mBCC, histologic confirmation of distant BCC metastasis (e.g., lung, liver, lymph nodes, or bone), with metastatic disease that is RECIST measurable using CT or MRI
. For patients with locally advanced BCC, histologically confirmed disease with at least one lesion that was 10 mm or more in at least 1 dimension by color photograph that is considered to be inoperable or medical contraindication to surgery (see below), in the opinion of a Mohs dermatologic surgeon, head and neck surgeon, or plastic surgeon
. Acceptable medical contraindications to surgery include:
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Determination of RP2D
Timeframe: Cycle 1, twenty-eight (28) day continuous dosing schedule
. BCC that has recurred in the same location after two or more surgical procedures and curative resection is deemed unlikely
. Anticipated substantial morbidity and/or deformity from surgery (e.g., removal of all or part of a facial structure, such as nose, ear, eyelid, eye; or requirement for limb amputation)
Exclusion criteria
. Tumor histology consistent with basosquamous carcinoma (basal cell carcinoma with squamous differentiation or metatypical carcinoma).
. Pregnant or nursing women. NOTE: Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; or abstinence) prior to study entry and for the duration of study participation. Should a man father a child, or a woman become pregnant or suspect she is pregnant while participating in this study, he or she should inform the treating physician immediately.
. Concurrent non-protocol-specified anti-tumor therapy (e.g., chemotherapy, other targeted therapy, radiation therapy, or photodynamic therapy)
. History of other malignancies within 3 years of Day 1, except for tumors with a negligible risk for metastasis or death, such as adequately treated squamous-cell carcinoma of the skin, ductal carcinoma in situ of the breast, or carcinoma in situ of the cervix
. Active or uncontrolled infections or with serious illnesses or medical conditions which would not permit the patient to be managed according to the protocol.
. History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or that might affect interpretation of the results of the study or renders the patient at high risk from treatment complications
. Difficulty with swallowing oral medications
. Chronic diarrhea (excess of 2-3 stools/day above normal frequency)
