Trial Title: Topical Tazarotene Vs Placebo In Hand-Foot-Skin Reactions

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Participants must have histologically or cytologically confirmed solid tumors with a plan to initiate regorafenib, or having started regorafenib in the last 48 hours, via dose escalation protocol describe in the ReDOS study in CRC. The ReDOS study recommends this dose escalation of regorafenib:80mg daily x 1 week, 120mg daily x 1 week, 160mg daily times one week, off week, then 160mg daily goal, or maximum tolerated dose thereafter. This is not a separate study; this is the current standard of care for regorafenib dosing. In addition, to compare across the cohorts, patients must be ambulatory with full use of all 4 distal extremities.~* Age ≥ 18~* ECOG performance status ≤2 (Karnofsky ≥60%, see Appendix A)~* Participants must have sufficient organ and marrow function in the opinion of the treating investigator. This can be based on lab reports from an outside facility.~* Women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation Tazarotene is known to be teratogenic, although the dose required with topical application to affect the developing human fetus is unknown. 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. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of administration.~* Women of child-bearing potential (WOCBP) must have a negative serum pregnancy test.~* Ability to understand and the willingness to sign a written informed consent document~Exclusion Criteria:~* Regorafenib use in combination with another TKI (unless regorafenib was started in the last 48 hours)~* Pregnancy or non-compliance with contraception (4 weeks before, during and for at least 3 ovulatory cycles after treatment cessation). Pregnant women are excluded from this study because tazarotene is category X with the potential for teratogenic or abortifacient effects.~* Nursing or lactating: Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with tazarotene, breastfeeding should be discontinued if the mother is treated.~* A history of hypervitaminosis A~* Other systemic retinoids needed for another condition (ie. Isotretinoin for inflammatory acne, acitretin for psoriasis, bexarotene for CTCL).~* Need for treatment dose systemic steroids or systemic immunosuppressive agents (i.e., for autoimmune disease or cerebral edema) at the time of enrolment~* Psoriasis or other autoimmune disease requiring skin directed or systemic therapy known to impact keratinocyte proliferation (UV therapy to the hands or feet, TNF inhibitors, etc).~* Active skin disease of the hands or feet with redness, scaling or blisters prior to enrolment~* Participants who have had any systemic chemotherapy or immunotherapy within 4 weeks prior to entering the study AND who have not recovered from adverse events on the hands and feet due to the agents administered.~* Participants who are receiving any other investigational agents to treat HFSR.~* Uncontrolled intercurrent illness including, but not limited to, uncontrolled lower extremity edema, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
