A Phase I/II Study of BEZ235 in Patients With Advanced Solid Malignancies Enriched by Patients With Advanced Breast Cancer

Plain-language summary
This is a first-in-human, phase I/Ib clinical research study with BEZ235, an inhibitor of phosphatidylinositol 3'-kinase (PI3K). The study consists of a dose escalation part followed by a safety dose expansion part:
Dose escalation part (advanced solid tumors, including patients with breast cancer being treated with trastuzumab):
Patients receive oral BEZ235 once daily on days 1-28 of the first course. Courses will repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of at least 3 patients receive escalating doses of BEZ235, as single agent or in combination with trastuzumab, until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose expected to produce during the first course of treatment dose-limiting toxicity in 33% of patients.
Once the MTD has been defined, the safety expansion parts of the trial will be opened for enrollment.
Safety dose expansion part (advanced solid tumors, including patients with breast cancer being treated with trastuzumab):
Patients will be treated with BEZ235, as single agent or in combination with trastuzumab, given at the MTD, once daily. Treatment of patients will continue until disease progression or occurrence of unacceptable side effects.

Inclusion Criteria:
\[Single agent dose escalation arm\]: Patients with histologically-confirmed, advanced unresectable solid tumors including CS patients who have progressed on (or not been able to tolerate) standard therapy within three months before screening visit or for whom no standard anticancer therapy exists.
\[Combination part\]: Patients with metastatic HER2+ Breast Cancer, after failure of trastuzumab treatment. Eligible patients will have to have tumors carrying molecular alterations of PIK3CA and/or PTEN.
\[Single agent safety expansion arm\]: Patients with histologically-confirmed, advanced unresectable solid tumors including CS patients who have progressed on (or not been able to tolerate) standard therapy within three months before screening visit or for whom no standard anticancer therapy exists. Patients will be prescreened for molecular alterations affecting PIK3CA and/or PTEN. Patients with NSCLC will also be pre-screened for EGFR mutation.
Exclusion Criteria:
* Patients who have brain metastases, which are progressive and/or requiring medical intervention for symptom control
* Prior treatment with a PI3K inhibitor
* Acute or chronic liver disease or renal disease
* Acute or chronic pancreatitis
* Patients with unresolved diarrhea ≥ CTCAE grade 2
* Impaired cardiac function or clinically significant cardiac diseases
* Patients with diabetes mellitus requiring insulin treatment
* Patients with known coagulopathies
* Patients with a history of photosen…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
determine the maximum Tolerated Dose (MTD) of BEZ235 as single agent and in combination with trastuzumab (Dose escalation part)
Timeframe: at end of study
2
assess the safety & tolerability of BEZ235 SDS as single agent and in combination with trastuzumab administered to patients at the MTD level (Safety expansion part)
