Brief Summary:
The purpose of CTO-IUSCC-0730 study is to assess the clinical efficacy of LY3214996 in combination with abemaciclib at the recommended phase 2 dose of LY3214996 200 mg orally daily and abemaciclib 150 mg orally twice daily. Patients will be treated until evidence of disease progression, non-compliance with study protocol, unacceptable major toxicity, at subject's own request for withdrawal, or if the study closes for any reason.

Primary Outcome Measures :
  1. Overall response rate [ Time Frame: from cycle 1 day 1 until safety follow up visit (up to 1 year) ]
    the number of patients who achieve a best overall response of complete response (CR) or partial response (PR) divided by the total number of patients treated (safety population)

Secondary Outcome Measures :
  1. Incidence of Adverse Events [ Time Frame: baseline until safety follow up visit (up to 1 year) ]
    CTCAE Version 5.0 will be used to summarize adverse events in the assessment of safety for incorporating LY3214996 in combination with abemaciclib. Summaries of treatment related adverse events in the population will be tabulated. All adverse events (AEs) will be presented in incidence tables coded by CTC term.

  2. Duration of Overall Response Rate [ Time Frame: up to 1 year ]
    measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented

  3. Duration of Progression free survival [ Time Frame: up to 1 year, 1 month ]
    the time from the date of start of treatment to the first date of the observed clinical or radiologically documented PD or death due to any cause, whichever occurs first. For patients who are not known to have died or progressed as of the data-inclusion cut-off date, PFS time will be censored at the date of the last objective progression-free disease assessment prior to the date of any subsequent systematic anticancer therapy.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Have a histological or cytological diagnosis of advanced unresectable or metastatic cancer (American Joint Committee on Cancer Staging Criteria) (Edge et al. 2009).

2. The patient must be, in the judgement of the investigator, an appropriate candidate for experimental therapy, either after available standard therapies (per available local guidelines) have failed to provide clinical benefit for their disease or after the patient has refused standard treatments.

3. Have one of the following alterations as defined below using a CLIA-certified next-generation sequencing test:

a. Point mutation in BRAF, RAF1, MEK1/2, or ERK1/2 that have been previously characterized to be gain-of-function mutations. These mutations have to be specified as gain-of-function as listed in the OncoKB and/or JAX-CKB databases. i. Patients with NSCLC that harbor BRAF V600E treated with prior RAF and/or MEK inhibition therapy will be excluded.

ii. Patients with tumor types other than NSCLC that harbor BRAF V600E mutations who have been treated and progressed on prior BRAF and/or MEK inhibition will be included.

iii. Patients with NSCLC that harbor BRAF V600E will only be enrolled if they are not a candidate for FDA approved therapy

  1. Amplification of RAF1 defined as >6 copies of the respective gene.
  2. Gene fusion in which BRAF, RAF1, MEK1/2, or ERK1/2, is a fusion partner; in which the fusion is determined to be in-frame; and the kinase domain of BRAF, RAF1, MEK1/2, or ERK1/2 is retained.
  3. Point mutations, frameshift insertions/deletions, splice site mutations, or stop gain mutations that results in loss-of-function of NF1.

    4. Have measurable disease amenable to biopsy. If biopsy is deemed unsafe at time of procedure, patients will remain eligible for study.

    5. Must be able to provide written informed consent and HIPAA authorization for release of personal health information.

    6. Have a performance status (PS) of 0 or 1 on the Eastern Cooperative Oncology (Group (ECOG) scale (Oken et al. 1982) within 21 (+/-7) days prior to registration for protocol therapy.

    7. Have discontinued previous systemic treatments > 3 weeks for cancer prior to first dose of investigational therapy. Patient must have resolution, except for alopecia, of all clinically significant toxic effects of prior chemotherapy, surgery, or radiotherapy to Grade ≤1 by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0.

    8. Have adequate organ function, as defined below: Laboratory Value (Abbreviations: ALT = alanine aminotransferase; AST = aspartate aminotransferase; ANC = absolute neutrophil count; ULN = upper limit of normal.) Hematologic ANC ≥1.5 × 109/L Platelets ≥100 × 109/L Hemoglobin ≥9.0 g/dL Transfusions to increase the patient's hemoglobin level to 9 g/dL are not permitted within 1 week prior to the baseline hematology profile Hepatic Total bilirubin ≤1.5 × ULN OR <2.0 mg/dL in patients with Gilbert's disease ALT and AST ≤2.5 × ULN OR ≤5 × ULN if the liver has tumor involvement Renal Serum creatinine OR Calculated creatinine clearance (see Appendix 3) ≤1.5 × ULN OR ≥50 mL/min

Exclusion Criteria:

  1. Have a serious concomitant systemic disorder (for example, active infection or a gastrointestinal disorder causing clinically significant symptoms such as nausea, vomiting or diarrhea, or profound immune suppression) that, in the opinion of the investigator, would compromise the patient's ability to adhere to the protocol.
