Brief summary

This phase II trial studies how well ibrutinib works in treating patients with stage IV melanoma of the skin that has not responded to previous treatment. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description

PRIMARY OBJECTIVES: I. Estimate rate of objective response (OR: complete response \[CR\] + partial response \[PR\]) to ibrutinib administered as single agent in patients with immune checkpoint inhibitor-refractory, or immune checkpoint inhibitor ineligible and mitogen-activated protein kinase (MAPK) inhibitor-refractory (if B-Raf proto-oncogene, serine/threonine kinase \[BRAF\]V600-mutant) or MAPK inhibitor-intolerant distant metastatic cutaneous melanoma. SECONDARY OBJECTIVES: I. Estimate progression-free survival (PFS) rate at 6 months after initiation of ibrutinib in patients with immune checkpoint inhibitor-refractory or immune checkpoint ineligible and MAPK inhibitor-refractory (if BRAFV600-mutant) or MAPK inhibitor-intolerant distant metastatic cutaneous melanoma. II. Estimate overall survival (OS) after initiation of ibrutinib in patients with immune checkpoint inhibitor-refractory or immune checkpoint ineligible and MAPK inhibitor-refractory (if BRAFV600-mutant) or MAPK inhibitor-intolerant distant metastatic cutaneous melanoma. III. Explore the association of ITK protein expression with OR and PFS. TERTIARY OBJECTIVES: I. Explore association between other putative targets of ibrutinib (e.g. Tec, ErbB4, Hck, Yes, BTK) in melanoma cells, as assessed by 2-color immunofluorescence (IF) in representative tissue sections obtained from pretreatment archived formalin-fixed paraffin-embedded (FFPE) tumor blocks or FFPE blocks obtained from fresh tissue biopsy from enrolled patients, with overall response (OR) and PFS. II. Explore ibrutinib-mediated effect(s) on immune cell subsets associated with immunomodulation by performing multiparameter flow cytometric analysis in peripheral blood mononuclear cell (PBMC) obtained prior to treatment, on day 29 (i.e., predose day 1 of cycle 2) following initiation of treatment with ibrutinib, and at the time of disease progression (3 time points). III. Determine pharmacokinetics (PK) of ibrutinib following daily dosing at 840 mg on day 8 of cycle 1 (Css). OUTLINE: Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for up to 2 years.

subjects with MAPK inhibitor-intolerance are eligible if they meet criteria * Documented disease refractory to at least one PD1/PD-L1 inhibitor, defined as disease progression following at least 2 infusions of the same drug; radiographic disease progression will be documented by the institutional radiologist based on any radiographic evidence (magnetic resonance imaging \[MRI\], computed tomography \[CT\], positron emission tomography \[PET\], or other modalities, etc.) of disease progression on two separate radiographic scans assessment obtained at least 4 weeks apart; this minimum 4-week interval is required to define PD-1 inhibitor resistance based on imaging; alternatively, clinical disease progression may be documented on examination by the treating investigator * Prior treatment-related toxicity resolved to =\< grade 1 or baseline with the exception of alopecia and permanent grade =\< 2 toxicities related to prior immune checkpoint inhibitor treatment (e.g. PD-1/PD-L1, CTLA-4, CD40, LAG3) treatment with the review and approval by the lead principal investigator (PI) * Prior radiation allowed (no restriction on amount); measurable lesion(s) may not have been previously irradiated * Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%) * Life expectancy of greater than 3 months * Hemoglobin \>= 9.0 g/dL * Absolute neutrophil count (ANC) \> 1,500/uL * Platelets \> 100,000/uL * Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2 x upper limit of normal (ULN);

abstinence) prior to study entry, for the duration of study participation and for 90 days after completion of ibrutinib administration; 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 90 days after completion of ibrutinib administration * Negative serum pregnancy test within 7 days of treatment initiation with ibrutinib in women of childbearing potential (WOCBP) * Ability to swallow oral medications * Patients with autoimmune disease requiring systemic corticosteroid treatment (and previously ineligible to receive systemic immunotherapies for melanoma) are allowed on condition that they do not receive more than 20 mg of daily dose methylprednisolone, prednisone, or its equivalent; this does not include autoimmune diseases caused by previous immunotherapy treatments for melanoma that require ongoing treatment with corticosteroids (e.g. autoimmune colitis or autoimmune hepatitis receiving corticosteroids) * Willing to consent to allow access to known archival tumor tissue (NOTE: designated pathologist from participating site OR lead principal investigator must sign-off to ensure sufficient tumor should be available for support of tumor imaging studies \[multi-color immunofluorescence\]) * If archival tumor tissue from a metastatic melanoma lesion is unavailable OR designated pathologist from participating site cannot sign-off to ensure that sufficient tumor is available from existing archival tumor block for support of tumor imaging studies, patients must be willing to consent to undergo a biopsy to collect metastatic tumor tissue; collection of fresh biopsy tissue does not guarantee enrollment, unless the pathologist from the participating site signs-off that sufficient tumor has been collected * Ability to understand and the willingness to sign a written informed consent document * Subjects who are unable to tolerate BRAF inhibitor and/or MEK inhibitor therapy due to grade \>= 2 toxicity (Common Terminology Criteria for Adverse Events \[CTCAE\] version \[v\]4.0) from these agents, irrespective of antitumor response, are eligible on condition that: (a) toxicities persisted despite change from doublet to singlet therapy (i.e. from concurrent BRAF inhibition plus MEK inhibition to BRAF inhibition alone), (b) toxicities are attributed to a class effect, and therefore switch from one drug to another is expected to induce the same type of toxicity (e.g. ocular toxicities or cardiac dysfunction from MEK inhibitor), (c) drug-specific toxicities that do not resolve with switch from one BRAF inhibitor to another (i.e. dabrafenib to vemurafenib, or vice versa), will be eligible for enrollment in 9922; in other words, patients will be allowed to enroll into the NCI9922 study despite lack of progression to MAPK inhibitor treatments, on condition that grade 2 or higher toxicities attributed to MAPK inhibitors resolve to grade 1, or less, at the time of study enrollment
