About

The study was designed to identify and register practical observations and experiences in connection with planning and implementing decentralized, patient-centered clinical trials at a geographic distance with virtual elements.

Full description

The purpose of this open-label, single arm, multi-center, Phase II interventional pilot trial was to evaluate if a decentralized clinical trial (DCT) using a telemedicine platform offers a satisfactory, safe and suitable management for HR-positive/HER2-negative participants with advanced breast cancer harboring a PIK3CA mutation and treated with alpelisib plus fulvestrant. The trial utilized a hybrid DCT approach to reduce participant burden by bringing visits, services, and supplies closer to them.

The planned duration of treatment was 12 cycles of 28 days. Participants could discontinue treatment earlier due to unacceptable toxicity, disease progression and/or decision made at the discretion of the investigator or the participant.

On-site visits occurred during screening, at Cycle 1 Day 1 (baseline), and at end-of-trial. Visits at the local oncologist practice were planned on Day 1 of Cycle 2, Cycle 4, Cycle 7, and Cycle 10. Other visits were performed by a district nurse, either at home or at the local oncologist's practice, depending on the participant's preference.

During the on-site visit on Cycle 1, Day 1, participants were trained on using the telemedicine platform, and other monitoring devices used during remote participation: a glucometer and a smartphone with the telemedicine application installed. Study treatment was also initiated during this visit. The participants were then transitioned to remote participation enabled by the telemedicine platform with support of local healthcare providers (local oncologist, district nurse, or other qualified healthcare professional) under the investigator's oversight.

Discontinuation of remote participation was not a reason for trial termination. Participants who did not wish to continue with remote participation had the option to attend on-site visits.

The study planned to enroll approximately 20 participants, however the study was terminated prematurely with only 2 participants enrolled. The decision to terminate the study was due to delays during the start-up period and due to low enrollment. The decision to terminate was not related to any potential safety concern with alpelisib.

Inclusion and exclusion criteria

Key Inclusion Criteria:

1. Participant is an adult ≥18 years old at the time of consent
2. Participant with ABC (loco regionally recurrent or metastatic) not amenable to curative therapy.
3. Participant with a histologically and/or cytologically confirmed diagnosis of ER-positive and/or PR-positive breast cancer by local laboratory.
4. Participant with a confirmed HER2-negative ABC.
5. Participant with a pathology report confirming PIK3CA mutant status by a certified laboratory using a validated PIK3CA mutation assay (from either tissue or blood).
6. Participant was willing to operate a smartphone compatible with the software of the medical device and willing to manage applications
7. Participant was willing to use the telemedicine platform and to follow the remote participant monitoring procedure.

Key Exclusion Criteria:
