Plain English Summary

Background and study aims
Breast cancer is the most commonly diagnosed cancer in women, with an estimated global incidence of 2,088,849 new cases and 626,679 deaths reported in 2018. Current treatments for advanced or metastatic disease focus on prolonging life and improving or maintaining quality of life. Preventing resistance to therapy and ultimately achieving a cure remain unmet needs in this disease setting.

Standard-of-care treatment options for patients with de novo metastatic disease, or for whom disease recurs following surgery and adjuvant treatment, include endocrine therapy, endocrine and targeted therapy combinations, or chemotherapy. For most patients, endocrine therapy alone or in combination with a targeted therapy is the treatment of choice in the metastatic setting.

Inavolisib as a single agent, or inavolisib in combination with other anti-cancer therapies, is being developed by Roche, for the treatment of locally advanced tumors or solid tumors with the PIK3CA-mutatation that have spread to other sites, including breast cancer. The development of inavolisib as a single agent and in various other combinations for other indications beyond breast cancer is ongoing.

This study will investigate the absorption, metabolism, excretion, and bioavailability of inavolisib in healthy volunteers. Information on the amount of active inavolisib available to the body using the current method of taking the drug will be helpful to plan future studies and may be useful to interpret data from these studies on how inavolisib moves through and interacts with the body. The results from this study may guide future study designs using special populations or evaluating the potential for drug-drug interactions.

Who can participate?
Up to 8 healthy male and female volunteers aged 18 to 65 years. Male volunteers are limited to 3 volunteers or less.

What does the study involve?
Participants will receive a single dose (9 mg) of inavolisib as a capsule taken by mouth in a fasted state. After 2 h 58 min, participants will receive a single intravenous infusion (100 μg) of inavolisib. Participants will be followed up for collection of blood, urine, and fecal samples over the following 336 h period.

What are the possible benefits and risks of participating?
High blood sugar, inflammation or ulcers of the mouth, rash, and diarrhea have been identified as risks for people receiving inavolisib treatment. These risks may require either stopping or reducing the dose of inavolisib and may have the potential to cause life-threatening conditions. Therefore, close monitoring and a robust risk-mitigation strategy will be used during this study. Results in previous studies have shown the inavolisib is well tolerated and there are no additional safety concerns beyond those associated with expected toxicities and effects of this class of drugs.

Where is the study run from?

When is the study starting and how long is it expected to run for?
From November 2020 to April 2021

Scientific titleA phase 1, open-label, single-center study to investigate the absorption, metabolism, excretion, and absolute bioavailability of a single oral dose of [14C]-labeled inavolisib and an iv tracer dose of [13C6]-labeled inavolisib in a single cohort of healthy volunteers
Study hypothesisTo investigate the absorption, metabolism, excretion, and absolute bioavailability of Inavolisib in healthy volunteers
Ethics approval(s)Approved 09/02/2021, Salus IRB (2111 W. Braker Lane, Suite 100, Austin, Texas 78758, USA; +1 512-380-1244; salus@salusirb.com), ref: GP42652
ConditionThe absorption, metabolism, excretion, and bioavailability of a PI3K inhibitor drug in healthy volunteers
InterventionThe participants will each receive a single 9 mg (approximately 200 μCi) oral capsule dose of [14C]-inavolisib administered in a fasted state and followed after 2 h 58 min by a single 100 μg intravenous (IV) dose of [13C6]-inavolisib administered as an IV push over 2 min. Participants will be followed up for regular collection of blood, urine, and fecal samples over a 336 h period.
