Hormone receptor positive HER2 negative breast cancer

Objectives

The primary objective of this study is to evaluate the **efficacy** of different treatment arms in patients with early-stage, Hormone Receptor (HR)-positive / Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer. This is assessed by the rate of patients achieving a 90% decrease or clearance in baseline circulating tumor DNA (**ctDNA**) at three months. This objective is clinically relevant as it aims to determine the potential of these treatments to significantly reduce tumor burden, which could correlate with improved patient outcomes and reduced risk of relapse.

Secondary objectives include:

Assessing the incidence of ctDNA detection in patients with HR-positive/HER2-negative breast cancer.
Evaluating the efficacy of the experimental arms in terms of a 90% decrease in baseline ctDNA at six, nine, and 12 months.
Evaluating the efficacy in terms of a 90% decrease in baseline ctDNA at three months and maintained at six and 12 months.
Evaluating the efficacy in terms of a 50% and 70% decrease in baseline ctDNA at three, six, nine, and 12 months.
Evaluating the efficacy in terms of time to rising ctDNA during the study follow-up.
Evaluating the duration of efficacy in terms of time with at least a 90% decrease in baseline ctDNA.
Evaluating the ctDNA decrease relative to baseline at three, six, nine, and 12 months.
Evaluating the safety and tolerability of the different treatments.
Assessing the performance of F1Tracker to monitor Minimal Residual Disease (MRD) based on ctDNA levels.
Exploratory analyses may include assessing whether giredestrant, alone or in combination with abemaciclib or inavolisib, improves relapse-free survival compared to standard endocrine therapy in patients with detectable ctDNA during adjuvant therapy, and investigating the association between genetic markers, ctDNA changes, and response to treatment.

Participants

The clinical trial involves a total of **627 participants** diagnosed with **early-stage, Hormone Receptor (HR)-positive / Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer**. The study population includes both male and female subjects, aged 18 years and older, with a focus on individuals who are considered part of a vulnerable population. Participants were selected based on specific criteria, including the absence of metastatic disease and a history of surgery for primary breast cancer with clear margins. The trial considers lifestyle factors such as adherence to endocrine therapy (ET) and, for some participants, the use of luteinizing hormone-releasing hormone (LHRH) agonist therapy. The study population is characterized by adequate hematologic and organ function, and participants must be able to swallow and absorb oral medication. The trial does not specify dietary or physical activity requirements, but participants must adhere to study procedures and contraceptive guidelines if applicable. The selection process ensures that participants have not received prior treatment with certain inhibitors or therapies, maintaining a focus on those with high-risk early-stage breast cancer.

Plans and Procedures

The clinical trial is designed to evaluate the efficacy of various treatments by monitoring **Minimal Residual Disease** using circulating tumor DNA (ctDNA) in patients with early-stage, hormone receptor-positive, and HER2-negative breast cancer. This is a randomized, double-blind, controlled trial with an estimated duration extending until June 2028. The trial is divided into two main phases: a surveillance phase and a treatment phase. The primary objective is to assess the proportion of patients achieving at least a 90% decrease or clearance in baseline ctDNA at three months post-treatment initiation.

Participants will undergo a series of study visits, beginning with an inclusion (screening) visit to confirm eligibility based on specific criteria, such as the absence of metastatic disease and adequate hematologic and organ function. The surveillance phase requires patients to have undergone surgery for their primary breast cancer with documented clear margins within the past five years. During the treatment phase, participants must exhibit ctDNA positivity without clinical or radiologic recurrence and have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

Follow-up visits will occur at regular intervals to monitor ctDNA levels and assess treatment efficacy and safety. The end-of-study visit will conclude the participant's involvement, which is expected to last up to 24 months for most treatment arms, with some extending to 60 months. Conditions that may lead to early termination from the study include the development of significant adverse events, non-compliance with study procedures, or withdrawal of consent.

The trial involves the administration of oral medications, including Verzenios (abemaciclib), INAVOLISIB, and RO7197597, each with specific dosing regimens and treatment durations. The study aims to provide valuable insights into the effectiveness of these treatments in reducing ctDNA levels, thereby potentially improving outcomes for patients with this subtype of breast cancer.

Treatment

The clinical trial involves the administration of **Verzenios** 150 mg film-coated tablets, which contain the active substance **abemaciclib**. This medication is provided in the form of film-coated tablets and is administered orally. The maximum daily dose is 300 mg, with a total maximum dose of 219,000 mg over a treatment period of up to 24 months. Abemaciclib is a chemical compound and is used in conjunction with endocrine therapy as part of the treatment regimen. Participant compliance with the dosing schedule is monitored throughout the trial.

Another experimental medication used in the trial is **INAVOLISIB**, a film-coated tablet containing the active substance **inavolisib**. This medication is also administered orally, with a maximum daily dose of 9 mg and a total maximum dose of 6,570 mg over a 24-month treatment period. Inavolisib acts as a selective inhibitor of the Class I PI3Kalpha isoform (p110alpha). The chemical nature of inavolisib is confirmed, and its administration is carefully monitored to ensure adherence to the prescribed dosing schedule.

The trial also includes the administration of **RO7197597**, a hard capsule formulation containing the active substance **giredestrant**. This medication is administered orally, with a maximum daily dose of 30 mg and a total maximum dose of 54,750 mg over a treatment period of up to 60 months. Giredestrant is a small-molecule, selective estrogen receptor degrader (SERD) and is of chemical origin. The administration of this medication is monitored to ensure participant compliance with the dosing regimen.

In addition to the experimental medications, standard-of-care therapies, including endocrine therapy, are utilized as part of the treatment protocol. The trial does not employ a placebo or comparator treatment. All medications are administered according to the specified dosing schedules, and participant adherence is closely monitored to ensure the integrity of the trial data.

Efficacy

The efficacy of the clinical trial will be assessed by evaluating the **Minimal Residual Disease** (MRD) using circulating tumor DNA (ctDNA) in patients with hormone receptor-positive (HR-positive) and human epidermal growth factor receptor 2-negative (HER2-negative) early breast cancer. The primary endpoint for the treatment phase is the proportion of patients achieving at least a 90% decrease or clearance in baseline ctDNA at three months after the initiation of study treatment. Secondary endpoints include the proportion of patients with a 90% decrease in baseline ctDNA at six, nine, and 12 months, as well as the maintenance of this decrease at six and 12 months. Additional secondary endpoints involve the proportion of patients with 50% and 70% decreases in baseline ctDNA at specified timepoints, time to rising ctDNA, duration of at least a 90% decrease in ctDNA, and the best percentage of ctDNA decrease relative to baseline at six, nine, and 12 months.

The efficacy parameters will be measured and collected through ctDNA tests conducted at various timepoints, including three, six, nine, and 12 months after the initiation of study treatment. The analysis will focus on the changes in ctDNA levels compared to baseline measurements. The performance of the F1Tracker tool to monitor MRD will also be evaluated as part of the study's secondary endpoints. The safety and toxicity profile will be assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. The trial is designed to provide a comprehensive evaluation of the efficacy of the study treatments in reducing MRD in the specified patient population.
