Foresight Diagnostics and Leading Global Cancer Center to Present New Data on Foresight CLARITY™ Ultra-Sensitive MRD Detection in Early-Stage Breast Cancer at the 2024 San Antonio Breast Cancer Symposium

On November 25, 2024 Foresight Diagnostics (Foresight) reported new data from its ultra-sensitive Foresight CLARITY minimal residual disease (MRD) platform in early-stage breast cancer that will be presented at the 2024 San Antonio Breast Cancer Symposium (SABCS) this month (Press release, Memorial Sloan-Kettering Cancer Center, NOV 25, 2024, View Source [SID1234648638]).

Foresight and Memorial Sloan Kettering (MSK) will present an analysis of 470 samples from 81 early-stage breast cancer patients demonstrating that ctDNA clearance following various perioperative treatments – including surgery, neoadjuvant chemotherapy, and adjuvant chemotherapy – is strongly associated with favorable survival outcomes.

Key findings from the research include:

34% of pre-treatment and 68% of post-treatment samples with detectable ctDNA had ctDNA levels <10-4 (<0.01%), the approximate sensitivity limit for 1st generation ctDNA-MRD assays. All samples obtained post-neoadjuvant treatment with detectable ctDNA had tumor fractions <10-4.
Upfront surgery cleared ctDNA in the majority of patients with detectable baseline ctDNA. This highlights the origin of ctDNA detection as either from primary or micrometastatic disease.
Post-surgical ctDNA-MRD positivity was associated with recurrence, and subsequent clearance of ctDNA-MRD by adjuvant therapy further predicted long-term recurrence-free survival.
All patients with disease progression who had end of treatment blood samples available had detectable ctDNA (n=9/9; 100% sensitivity).
"This analysis builds upon research presented earlier this year at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress. The consistency of Foresight CLARITY’s performance in early-stage breast cancer provides us as a field with the confidence to explore novel applications of minimal residual disease detection in advancing precision medicine research," said David Kurtz, MD, PhD, Foresight’s Chief Medical Officer and Head of Research. "We are particularly excited about the potential to investigate how molecular response monitoring might inform both treatment escalation and de-escalation strategies in future studies."

"These findings expand our understanding of how different breast cancer treatments affect molecular residual disease," said Pedram Ravazi, MD, PhD, breast medical oncologist and Director of Liquid Biopsy & Genomics at MSK. "By utilizing ultra-sensitive MRD detection at multiple timepoints throughout the patient treatment journey, we were able to differentiate responses to both local and systemic therapies. This level of insight opens new avenues for research into whether prospective, risk-based treatment decisions could potentially improve cure rates in the first-line setting in early-stage breast cancer."

The research is part of MSK’s Liquid Biopsy for INterception of Cancer (MSK-LINC) study, a prospective investigation assessing MRD detection during and after curative-intent therapy. The study spans diverse breast cancer subtypes, including hormone receptor-positive, HER2-positive, and triple-negative breast cancer.

The full data will be presented at SABCS 2024:

P2-01-25: "Circulating tumor DNA clearance by neoadjuvant chemotherapy or breast surgery detected using an ultrasensitive ctDNA MRD assay in early breast cancer."

ORSERDU Real-World Progression-Free Survival Data
ORSERDU is the first and only oral estrogen receptor antagonist (SERD) approved to target ESR1-mutated tumors, which occur in up to 50% of ER+, HER2- advanced or mBC tumors, as a result of prior exposure to endocrine therapy (ET) in the metastatic setting. Since its approval by the U.S. Food & Drug Administration (FDA) in January 2023, sufficient time has passed to be able to characterize the real-world use of ORSERDU in the current mBC treatment landscape.

Results to be reported at SABCS 2024 show the efficacy of ORSERDU in the real-world setting in patients with ER+/HER2- advanced or mBC. The overall population analysis demonstrated median rwPFS of 6.8 months. Median rwPFS for patients with 1-2 lines of prior ET in mBC was 8 months. The rwPFS observed is consistent across the subgroups in the analysis. Updated results and additional information from other patient subgroups will be presented at the congress.

The full abstract (SESS-1876) can be viewed here (page 1748).

"These exciting data show clinically meaningful real-world progression-free survival with ORSERDU monotherapy," said Virginia Kaklamani, MD, DSc, breast medical oncologist and professor of medicine, UT Health San Antonio, MD Anderson Cancer Center. "As a practicing physician, these results underscore the need to test patients’ tumors for the ESR1 mutation at each disease progression using liquid biopsy, so that we can appropriately tailor their treatment and optimize their care."

Elacestrant Plus Abemaciclib Combination Study
Both the ELEVATE and ELECTRA phase 1b/2 studies were designed with the objective to evaluate patient outcomes through combination treatment options, by overcoming a tumor’s resistance to ET.

Results to be reported at SABCS 2024 include updated efficacy results from the ELECTRA study which demonstrate favorable progression-free survival (PFS) data. In all efficacy-evaluable patients, median progression-free survival (mPFS) was 8.6 months. In patients with an ESR1 mutation, mPFS was 8.7 months. In patients without an ESR1 mutation, mPFS was 7.2 months.

Additionally, a pooled safety analysis of patients from ELECTRA and ELEVATE show a manageable and predictable safety profile in patients with ER+/HER2- mBC that is treated with elacestrant plus abemaciclib, and who previously received one or more lines of prior therapy. Safety was evaluated in all patients who received this combination and was consistent with the known safety profiles of both compounds. The most common all-grade adverse events (AEs) (≥20%) were diarrhea, nausea, neutropenia, vomiting, fatigue, anemia and decreased appetite. No Grade 4 AEs were observed.

The full abstract (SESS-1910) can be viewed here (page 3330).

"These updated results on the combination of elacestrant plus abemaciclib continue to show encouraging progression-free survival data, and a favorable safety profile, without any new toxicity signals when using these agents in combination," said Hope S. Rugo, MD, Professor of Medicine and Winterhof Family Endowed Professor in Breast Cancer, Director, Breast Oncology and Clinical Trials Education, University of California San Francisco. "Elacestrant continues to show potential to become an endocrine therapy backbone for combination regimens in metastatic breast cancer, and we are excited to explore this treatment combination further as these trials move forward."

"It is exciting to see these progression-free survival outcomes in a real-world setting, which shows ORSERDU brings a meaningful benefit for oncologists to offer their patients," said Elcin Barker Ergun, CEO of the Menarini Group. "We are committed to advancing our robust clinical research program on elacestrant and unlocking its full potential, both in monotherapy and combination treatment settings, with the goal of bringing ORSERDU to new patient populations which may benefit."

About The Elacestrant Clinical Development Program
Elacestrant is also being investigated in several company-sponsored clinical trials in metastatic breast cancer, alone or in combination with other therapies. EMERALD (NCT03778931) is a randomized Phase 3 trial, open label, active-controlled study evaluating elacestrant as second- or third-line monotherapy in ER+, HER2- advanced/metastatic breast cancer patients. ELEVATE (NCT05563220) is a phase 1b/2 clinical trial evaluating the safety and efficacy of elacestrant combined with alpelisib, everolimus, capivasertib, palbociclib, ribociclib or abemaciclib. ELECTRA (NCT05386108) is an open-label phase 1b/2, multicenter study evaluating elacestrant in combination with abemaciclib in patients with ER+, HER2- breast cancer. The phase 2 portion evaluates this treatment regimen in patients with brain metastases. ELCIN (NCT05596409) is a phase 2 trial evaluating the efficacy of elacestrant in patients with ER+, HER2- advanced/metastatic breast cancer who received one or two prior hormonal therapies and no prior CDK4/6 inhibitors in the metastatic setting. ADELA (NCT06382948) is a phase 3 randomized, double-blinded trial evaluating elacestrant in combination with everolimus in patients with ER+, HER2- mBC with ESR1-mut tumors. ELEGANT (NCT06492616) is a phase 3 study evaluating elacestrant versus standard endocrine therapy in women and men with node-positive, estrogen receptor-positive, HER2-negative, early breast cancer with high risk of recurrence. Elacestrant is also being evaluated in additional investigator-led trials, in trials conducted in collaboration with other companies, in metastatic breast cancer as well as in early disease.

Important Safety Information
Warning and Precautions

Dyslipidemia: Hypercholesterolemia and hypertriglyceridemia occurred in patients taking ORSERDU at an incidence of 30% and 27%, respectively. The incidence of Grade 3 and 4 hypercholesterolemia and hypertriglyceridemia were 0.9% and 2.2%, respectively. Monitor lipid profile prior to starting and periodically while taking ORSERDU.

Embryo-Fetal Toxicity: Based on findings in animals and its mechanism of action, ORSERDU can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ORSERDU and for 1 week after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ORSERDU and for 1 week after the final dose.

Adverse Reactions

Serious adverse reactions occurred in 12% of patients who received ORSERDU. Serious adverse reactions in >1% of patients who received ORSERDU were musculoskeletal pain (1.7%) and nausea (1.3%). Fatal adverse reactions occurred in 1.7% of patients who received ORSERDU, including cardiac arrest, septic shock, diverticulitis, and unknown cause (one patient each).

The most common adverse reactions (≥10%), including laboratory abnormalities, of ORSERDU were musculoskeletal pain (41%), nausea (35%), increased cholesterol (30%), increased AST (29%), increased triglycerides (27%), fatigue (26%), decreased hemoglobin (26%), vomiting (19%), increased ALT (17%), decreased sodium (16%), increased creatinine (16%), decreased appetite(15%), diarrhea(13%), headache (12%), constipation (12%), abdominal pain (11%), hot flush (11%), and dyspepsia (10%).
