Lilly

Status and phase: Completed; Phase 1

Conditions: Healthy; Renal Insufficiency

Treatments: Drug: Pirtobrutinib

Details and patient eligibility

About

The main purpose of this study is to measure how much of pirtobrutinib (LOXO-305) gets into the bloodstream and how long it takes the body to eliminate it in participants with impaired kidney function and healthy participants. The side effects and tolerability of pirtobrutinib will also be evaluated. Participation could last around 46 days.

Enrollment: 16 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participants with impaired renal function [estimated Glomerular Filtration Rate (eGFR): < 90 milliliters per minute (mL/min) per 1.73 square meters (m2)] and healthy participants with normal renal function [(eGFR: ≥ 90 mL/min/1.73 m2)].
• Males and females of non-childbearing potential.
• Within body mass index (BMI) range 18.5 to 40.0 kilograms per square meter (kg/m²).
• Participants will be in good health, based on medical history, physical examination findings, vital signs, 12 lead electrocardiogram (ECG), or clinical laboratory tests, as determined by the Investigator (or designee).
• Able to comply with all study procedures, including the 8-night stay at the Clinical Research Unit and follow-up phone call.

Exclusion criteria

• History or presence of any of the following, deemed clinically significant by the Investigator (or designee), and/or Sponsor:

  1. liver disease
  2. pancreatitis
  3. peptic ulcer disease
  4. intestinal malabsorption
  5. gastric reduction surgery
  6. history or presence of clinically significant cardiovascular disease.

• Participants with out-of-range, at-rest vital signs.

• Abnormal laboratory values determined to be clinically significant by the Investigator (or designee).

• Clinically significant abnormality, as determined by the Investigator (or designee), from physical examination.

• Participation in any other investigational study drug trial involving administration of any investigational drug in the past 30 days or 5 half-lives, whichever was longer, prior to the first dose administration (Day 1).

• Use or intention to use any prescription or over-the-counter medications within 14 days prior to the first dose administration (Day 1) and through end of trial.

• History or presence, upon clinical evaluation, of any illness that, in the opinion of the Investigator, would interfere with the ability to provide informed consent or comply with study instructions, or that might confound the interpretation of the study results, or put the participant at undue risk.

• Donation of blood from 56 days prior to Screening, plasma or platelets from 4 weeks prior to Screening.

• Receipt of blood products within 2 months prior to Check-in (Day -1).

• Significant history of hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator (or designee).
