Patient case: 64-year-old male with Cholangiocarcinoma. Genetic variant: IDH1 (R132H). Other conditions: Neuropathy.

Clinical trial: Phase 1/2 Study of ARQ 087 in Adult Subjects With Advanced Solid Tumors With FGFR Genetic Alterations

Summary: This is an open-label, Phase 1/2, dose escalation and signal finding study of ARQ 087 administered to subjects with advanced solid tumors with FGFR genetic alterations, including intrahepatic cholangiocarcinoma (iCCA) with FGFR2 gene fusion. The study is designed to explore the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of ARQ 087 and to define a RP2D of ARQ 087.


Eligibility: Inclusion Criteria:
  1. Signed written informed consent granted
  2. Men or women ≥18 years of age
  3. Histologically or cytologically confirmed, locally advanced, inoperable, or metastatic solid tumors. Subjects eligible for enrollment in the Expanded Cohort must have documented and/or confirmed FGFR genetic alterations, including iCCA with FGFR2 gene fusion.
  4. Failure to respond to standard therapy, or for whom standard therapy does not exist.
  5. Evaluable or measurable disease
  6. Archival and/or fresh biopsy tissue samples must be available prior to the first dose of the study drug
  7. Life expectancy ≥ 12 weeks
  8. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
  9. Hemoglobin (Hgb) ≥ 9.0 g/dL
  10. Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L
  11. Platelet count ≥ 100 x 10^9/L
  12. Total bilirubin ≤ 1.5 × upper limit of normal (ULN) (≤ 2 x ULN for subjects with cholangiocarcinoma)
  13. Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3 × ULN (≤ 5 x ULN for subjects with liver metastases)
  14. Serum creatinine ≤ 1.5 x ULN or creatinine clearance > 60 mL/min/1.73 m^2 for subjects with creatinine levels above institutional normal
  15. Albumin ≥ 2.8 g/dL
  16. INR 0.8 to ULN or ≤ 3 for subjects receiving anticoagulant therapy
  17. Men or women of child-producing potential must agree to use double-barrier contraceptive measures, oral contraception, or avoid intercourse during the study and for 90 days after the last dose of study drug
  18. Women of childbearing potential must have a negative serum pregnancy test during Screening Period and within 48 hours of the first dose of ARQ 087.
  Exclusion Criteria:
  1. Anti-cancer therapy, such as chemotherapy, immunotherapy, hormonal, targeted therapy, or investigational agents within four weeks or five times of the drug half life, whichever is longer, of the first dose of ARQ 087
  2. Major surgery or radiation therapy within four weeks of the first dose of ARQ 087
  3. Previous treatment with FGFR inhibitors
  4. History of allergic reactions attributed to compounds of similar chemical or biological composition as ARQ 087
  5. Unable or unwilling to swallow the complete daily dose of ARQ 087
  6. Clinically unstable central nervous system (CNS) metastasis
  7. History of myocardial infarction (MI) or congestive heart failure defined as Class II to IV per the New York Heart Association classification within 6 months of the first dose of ARQ 087 (MI occurring >6 months of the first dose of ARQ 087 will be permitted)
  8. Significant GI disorder(s) that could interfere with the absorption, metabolism, or excretion of ARQ 087 (e.g. Crohn's disease, ulcerative colitis, extensive gastric resection)
  9. History and/or current evidence of clinically relevant ectopic mineralization/calcification
  10. Previous malignancy within 2 years prior to the first dose of ARQ 087, except curatively treated non-melanoma skin cancer, carcinoma in-situ of the breast or cervix, or superficial bladder tumors
  11. Known human immunodeficiency virus (HIV) infection
  12. Concurrent uncontrolled illness not related to cancer, including but not limited to:
  -  Psychiatric illness/substance abuse/social situation that would limit compliance with study requirements.
  -  Uncontrolled diabetes mellitus
  13. Blood transfusion within 5 days of the blood draw being used to confirm eligibility
  14. Pregnant or breastfeeding
