Brief Summary:
The purpose of this study is to characterize the safety, tolerability, and determine the maximum tolerated dose (MTD) or the highest protocol-defined dose, in the absence of exceeding the MTD, of KHK2455 administered orally in combination with mogamulizumab to subjects with locally advanced or metastatic solid tumors.

Condition or disease Intervention/treatment Phase
Solid Tumor Cancer Carcinoma Drug: KHK2455 Drug: Mogamulizumab Phase 1

Detailed Description:

The study is designed as a 2-part, multicenter, open-label, Phase 1, dose-escalation, cohort-expansion study of KHK2455 as a monotherapy run-in (Cycle 0) followed by combination therapy with the anti-CCR4 antibody mogamulizumab (Cycle 1 and beyond).

Part 1 will identify the MTD or the highest protocol-defined dose, in the absence of exceeding the MTD, for the KHK2455 monotherapy run-in and for the combination regimen (KHK2455 monotherapy [Cycle 0] followed by KHK2455 + mogamulizumab combination [Cycle 1]). The dose escalation phase (Part 1) will enroll up to approximately 36 subjects.

Part 2, the cohort-expansion phase, will further explore the safety, tolerability, PK, PD, pharmacogenomics (PGx), and preliminary anti-tumor activity of KHK2455 administered as monotherapy and in combination with mogamulizumab in subjects with one cohort-specific tumor type. In Part 2, approximately 15 subjects with a selected tumor type will be enrolled and treated with the recommended KHK2455 dose established in Part 1 in combination with mogamulizumab.

Criteria

Inclusion Criteria:

  • Subject must have histological or cytological evidence of a solid malignancy
  • Subject must have measurable neoplastic disease according to the RECIST v1.1;
  • Subject must have locally advanced or metastatic solid tumor with no additional therapy options available that are known to provide clinical benefit per institutional standards;
  • Subject is able to understand and willing to sign the ICF, according to institutional standards, prior to the initiation of any study related procedures;
  • Subject must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
  • Subject must have a life expectancy of > 3 months, in the Investigator's judgment;
  • Subject must have a left ventricular ejection fraction of ≥ 50%;
  • Subject must have adequate organ function as defined below. The following parameters must be evaluated within 28 days prior to Cycle 0 Day 1 (monotherapy run-in period):

    • Aspartate aminotransferase (AST) and/or ALT ≤ 2.5 × ULN
    • Total bilirubin ≤ 1.5 × ULN
    • Hemoglobin ≥ 9.6 g/dL
    • Serum creatinine ≤ 2.0 × ULN
    • Absolute neutrophil count (ANC) ≥ 1000 cells/mm3
    • Absolute lymphocytes count ≥ 800 cells/mm3
    • Platelets ≥ 100 × 109/L
    • Albumin ≥ 2.0 g/dL
  • Subject has recovered (i.e., to Grade ≤ 1 or to a baseline level) from the effects of surgery, radiotherapy, chemotherapy, hormonal therapy, or other therapies for cancer; with the exception of vitiligo, alopecia, neuropathy, partial hearing loss, and/or endocrinopathies (for which no resolution is required);
  • Subject on prior chemotherapeutic, immunomodulator (such as anti-CTLA-4, anti-PD-1 or anti-PD-L1 inhibitor), investigational, or other therapies for the treatment of cancer must wait at least 28 days after the last dose of these therapies before administration of the first dose of the IMP.
  • Male subject and woman of child-bearing potential (WOCBP) must agree to use a medically-effective, double-barrier method of contraception (as defined in the ICF) to prevent pregnancy while on study and for 6 months after the last dose of IMP. WOCBP includes any female who has experienced menarche and who has not undergone successful surgical sterilization or is not postmenopausal (defined as amenorrhea ≥ 12 consecutive months without an alternative medical cause). If the subject is a WOCBP, she must have a negative serum pregnancy test at Screening and a negative urine pregnancy test on Cycle 0 Day 1 (monotherapy run-in period; prior to receiving KHK2455);
  • Subject must have a brain scan performed during Screening or within 3 months prior to signing informed consent;
  • Subject must be able to swallow solid dosage forms.

  • Subject is enrolled (concurrently) in another investigational study, with the exception of the follow-up period of another investigational study in which no anti-cancer therapy is being administered and where only data are being collected;
