Brief summary
This study aims to find the safest and most effective dose of a new investigational drug called Sapu003 (Everolimus). In women with advanced or metastatic breast cancer that is hormone receptor-positive (HR+) and HER2-negative (HER2–), Sapu003 will be given together with exemestane (a hormone therapy). In other participants with advanced solid tumours such as kidney cancer, liver cancer, neuroendocrine tumours, or tuberous sclerosis complex–related tumours, Sapu003 will be given on its own. Who is it for? You may be eligible for this study if you are an adult aged 18 years or older with one of the following conditions: - Post-menopausal women with Stage 4/metastatic or locally advanced breast cancer that is HR+ and HER2–. - Adults with advanced or metastatic solid tumours including renal cell carcinoma (kidney cancer), hepatocellular carcinoma (liver cancer), neuroendocrine tumours, or tuberous sclerosis complex–related tumours. You may also be asked to complete additional health checks with a study doctor to determine if you are able to enrol in this study. Study details All participants who choose to enrol in this study will be allocated to a treatment group to receive a dose of Sapu003 (Everolimus) that will be given intravenously (via a vein) once a week for a 4-week cycle. Participants who don't experience any dangerous side effects will be asked to continue receiving Sapu003 each month for up to 6 months. - Women with HR+/HER2– breast cancer will also take a single oral dose of exemestane daily so that any drug interactions between exemestane and Sapu003 can be studied. - Participants with other advanced solid tumours will receive Sapu003 alone. Higher doses of Sapu003 may be studied if the initial participant group reports no dangerous side effects. Participants will also be asked to provide additional blood samples throughout the study and to report any side effects they experience while taking the study drugs. It is hoped this research will determine a safe dose of Sapu003 for future trials and to see whether the combination of Sapu003 and exemestane shows promise in controlling cancer spread in patients with HR+/HER- breast cancer who are also post-menopausal.
Interventions
The investigational intervention consists of Sapu003 (Everolimus) for Injection, administered intravenously over 30 minutes once weekly in 4-week (28-day) cycles. Dose escalation will follow the Bayesian Optimal Interval (BOIN) design to determine the Maximum Tolerated Dose (MTD), with planned dose levels of 5 mg/m², 7.5 mg/m², and 10 mg/m², and an optional –1 cohort at 3.5 mg/m² if required for safety. Treatment will continue for up to 6 months or until disease progression, unacceptable toxicity, or withdrawal of consent. Dose escalation/de-escalation decisions will be made at the end of each cohort based on the Bayesian Optimal Interval (BOIN) design. Separate cohorts of patients are enrolled at each dose level. All patients at a given dose level must complete one full cycle (4 weekly infusions) before the next cohort at the higher dose can be enrolled. Sapu003 will be reconstituted in 0.9% Sodium Chloride Injection, USP (4 mg/mL), diluted in 250 mL 0.9% Sodium Chloride, stored at 2–8°C, protected from light, and administered using amber-covered IV tubing. All participants will also receive exemestane 25 mg orally once daily throughout the study, administered continuously in combination with Sapu003 until disease progression, unacceptable toxicity, or withdrawal of consent. Exemestane is a steroidal aromatase inhibitor that irreversibly suppresses estrogen synthesis and represents the standard of care for HR+/HER2- advanced breast cancer after progression on non-steroidal aromatase inhibitors. Participants must also be on stable doses of metformin or statins prior to enrollment, as these agents are expected to provide synergistic effects by modulating mTOR signaling and tumor metabolism. Supportive medications, including antiemetics and G-CSF for neutropenia, are permitted. Adherence to the Exemestane doses is assessed indirectly through patient reporting and documentation of concomitant medications at study visits.
The investigational intervention consists of Sapu003 (Everolimus) for Injection, administered intravenously over 30 minutes once weekly in 4-week (28-day) cycles. The study will enroll patients with advanced mTOR-sensitive solid tumors and will include two cohorts: Cohort A: Patients with HR+/HER2-negative breast cancer receiving Sapu003 in combination with exemestane. Cohort B: Patients with RCC, NETs, TSC-associated tumors, or HCC receiving Sapu003 as monotherapy. Dose escalation will follow the Bayesian Optimal Interval (BOIN) design to determine the Maximum Tolerated Dose (MTD), with planned dose levels of 5 mg/m², 7.5 mg/m², and 10 mg/m², and an optional –1 cohort at 3.5 mg/m² if required for safety.
