Phase 1 Study for Urothelial Cancer

Clinical Trial Title

A Phase 1, Open-Label, Dose-Escalation and Expansion Study of IK-175, an Oral Aryl Hydrocarbon Receptor (AHR) Inhibitor in Patients with Locally Advanced or Metastatic Solid Tumors and Urothelial Carcinoma

National Clinical Trial Number:

NCT04200963

Clinical Trial Protocol Description:

This study will be conducted in adult subjects diagnosed with any form of an advanced or metastatic solid tumors including urothelial carcinoma for which standard therapy is no longer effective or is intolerable. This is a phase 1, multi-center, open label study designed to assess safety and tolerability of IK-175 as a single agent and in combination with nivolumab, to determine the recommended phase 2 dose (RP2D). Disease response, pharmacokinetics (PK), pharmacodynamics, and response biomarkers will also be assessed.

Clinical Trial Eligibility Criteria:

In order to participate you must meet the following criteria:

  1. Are an adult patients at least 18 years of age.
  2. Have confirmed solid tumors (including urothelial carcinoma) that have locally recurrent or metastatic disease that has progressed on or following all standard of care therapies or are not a candidate for standard treatment.
  3. For patients with urothelial carcinoma to be enrolled in the Combination Treatment arm: Have confirmation of urothelial carcinoma and have unresectable locally recurrent or metastatic disease that has progressed on or following all standard of care therapies, or are not a candidate for standard treatment. Checkpoint inhibitor therapy with anti-PD-1 or anti-PD-L1 does not necessarily need to directly precede the study, but patients must have progressed on or within 3 months of receiving the last infusion/dose anti-PD-(L)1 therapy for inclusion in the Combination Treatment arm only.
  4. Have measurable disease.
  5. Have an accessible tumor that can be safely accessed for multiple core biopsies and patient is willing to provide tissue from newly obtain biopsies before and during treatment.

You will be excluded from the study if any of the following criteria apply to you:

  1. Have untreated symptomatic central nervous system (CNS) tumors or brain metastasis. Patients are eligible if CNS metastases are asymptomatic and do not require immediate treatment or have been treated and patients have neurologically returned to baseline (residual signs or symptoms related to the CNS treatment are permitted). In addition, patients must have been either off corticosteroids, or on a stable or decreasing dose of ≤10 mg daily prednisone (or equivalent) for at least 2 weeks prior to entering the Treatment period (Day 1).
  2. Have not recovered to ≤ Grade 1 or baseline from all adverse events (AEs) due to previous therapies.
  3. Have an active autoimmune disease that has required systemic treatment in past 2 years with the use of disease-modifying agents, corticosteroids, or immunosuppressive drugs; nonsteroidal anti-inflammatory drugs (NSAIDs) are permitted. Patients with type 1 diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
  4. Have any condition requiring continuous systemic treatment with either corticosteroids (>10mg daily prednisone equivalents) or other immunosuppressive medications within 2 weeks prior to first dose of study treatment. (Inhaled or topical steroids and physiological replacement doses of up to 10 mg daily prednisone equivalent are permitted in the absence of active clinically significant [ie, severe] autoimmune disease.)
