Effects of Lasofoxifene Versus Fulvestrant on Vaginal and Vulvar Symptoms in Patients With ESR1-Mutated, ER+/HER2-, Metastatic Breast Cancer From the ELAINE 1 Study

Article

Author: Goldfarb, Shari B ; Meisel, Jane L ; Portman, David J ; Carroll, Dominic ; Jenkins, Simon N ; Pluard, Timothy J ; Komm, Barry S ; Sammons, Sarah L

BACKGROUND:

Lasofoxifene, a novel endocrine therapy (ET), showed antitumor activity versus fulvestrant in women with ESR1-mutated, metastatic breast cancer (mBC) that progressed on prior ET (phase 2, ELAINE 1 study). We investigated changes in genitourinary syndrome of menopause (GSM) vulvar-vaginal symptoms with lasofoxifene and how patient/disease characteristics affect baseline vulvar-vaginal symptoms in ELAINE 1.

METHODS:

Women were randomized to oral lasofoxifene 5 mg/day or IM fulvestrant 500 mg (days 1, 15, and 29, then every 28 days) until disease progression/severe toxicity. Changes in mean vaginal (VAS) and vulvar (VuAS) assessment scales, and their composite (average of all symptom scores/patient), from baseline to week 16, and mean baseline VAS/VuAS scores by patient/disease characteristics, were descriptively summarized.

RESULTS:

Of 103 enrolled patients, 72 (70%) completed the VAS/VuAS (mean age 61.5 years). Vaginal (40%)/vulvar (25%) dryness and vaginal pain (22%) were the most frequently reported symptoms; 26% reported ≥1 moderate/severe symptom. Lasofoxifene decreased the mean composite VAS/VuAS, VAS, and VuAS from baseline to week 16 by 74%, 74%, and 79%, respectively; fulvestrant increased them by 36%, 15%, and 63%, respectively. Baseline vaginal/vulvar symptoms were more severe if patients were under age 40, had no visceral disease, used adjuvant tamoxifen previously, or had longer AI duration in the adjuvant/metastatic settings.

CONCLUSIONS:

Oral lasofoxifene (5 mg/day), but not fulvestrant, appears to improve GSM vaginal symptoms in women with mBC. These preliminary findings suggest further study is needed; such will be explored in the phase 3, registrational, ELAINE 3 trial in patients with ESR1-mutated, ER+/HER2- mBC.

A genetically encoded fluorescent whole-cell biosensor for real-time detecting estrogenic activities in water samples

Article

Author: Chen, Ling ; Yang, Junyi ; Ren, Hongqiang ; Yuan, Shengjie ; He, Ruonan ; Wu, Bing

Real-time monitoring of estrogenic activity in the aquatic environment is a challenging task. Current biosensors face difficulties due to their limited response speed and environmental tolerance, especially for detecting wastewater, the major source of estrogenic compounds in aquatic environments. To address these difficulties, this study developed a single fluorescent protein (FP) -based whole-cell bacterial biosensor named ER-Light, which was achieved by inserting the sensing domain of the estrogen receptor (ER) into the FP Citrine and expressing it in the periplasm of Escherichia coli. As designed, ER-Light enables the detection of net estrogenic activity in mixtures, represented by estradiol equivalent concentration (EEQ). ER-Light detects EEQ in 40 s with a detection limit of 4.55 × 10^-7 μM and a maximum working range of 1.1 × 10^-4 μM, demonstrating sufficient response speed, sensitivity, and working range. In addition, the ER-Light can survive and tolerate wastewater effluent. Satisfactory recoveries (91.0 % to 102.1 %) eliminated concerns about the matrix effect of wastewater. EEQs (Not detected-2.9 ×10^-5 µM) measured by ER-Light from the effluent of 9 wastewater treatment plants validate its practicality in detecting wastewater. This is the first attempt to integrate ER into FP-based biosensors for environment monitoring. Our findings provide valuable design rules for real-time detection of bioactivity effects in the environment, contributing to the safeguarding of ecological and human health.

Discovery of Thiochroman Derivatives as Potent, Oral Selective Estrogen Receptor Degraders and Antagonists for the Treatment of Endocrine-Resistant Breast Cancer

Article

Author: Hu, Wenhao ; Yang, Yushe ; Zhang, Dan ; Meng, Xin ; Leng, Xin-Yu ; Lu, Zhengyu ; Lei, Xiang ; Sun, Lulu ; He, Yongqi ; Kong, Deyu

Selective estrogen receptor degraders (SERDs) deplete the ER signaling pathway via antagonism and degradation of ERα and represent a promising strategy to tackle endocrine resistance. Here, we report a new class of SERDs by pharmacological evolution of a selective estrogen receptor modulator, lasofoxifene. The structure-activity relationship study and efforts to circumvent the issue of human ether-a-go-go-related gene led to the identification of compounds 51. This bifunctional compound displayed broad activity across a vast array of cell backgrounds and was capable of effectively degrading and antagonizing wild-type ERα and clinically relevant ERα mutants. 51 exhibited favorable pharmacokinetic properties and good brain penetration, with a brain/plasma ratio of 3.05, and significantly suppressed the growth of tumor in a tamoxifen-resistant MCF-7 Tam1 xenograft model. Overall, the study demonstrates 51 as a highly potent, oral, and brain penetrant ER degrader and pure antagonist, showing a good potential in overcoming endocrine resistance.

Sermonix Pharmaceuticals’ Lasofoxifene Is Well Tolerated, Demonstrates Promising Ki67 Suppression in Phase 2 I-SPY 2 Arm Evaluating Therapy in Neoadjuvant Breast Cancer Setting

COLUMBUS, Ohio, and SAN FRANCISCO, Nov. 02, 2024 (GLOBE NEWSWIRE) — Sermonix Pharmaceuticals Inc., a privately held biopharmaceutical company developing innovative therapeutics to specifically treat metastatic breast cancers (mBC), and Quantum Leap Healthcare Collaborative™ today broadly announced that in the Phase 2 clinical trial evaluating lasofoxifene as a neoadjuvant endocrine therapy in molecularly selected HR+/HER2-, locally advanced breast cancer, the investigational drug was well tolerated and demonstrated promising early activity in suppressing the Ki67 protein in both premenopausal and postmenopausal patients. Results from the study, an arm of the Endocrine Optimization Pilot Protocol (EOP), a sub-study of Quantum Leap’s ongoing I-SPY 2 TRIAL (Investigation of Serial studies to Predict Your Therapeutic Response with Imaging And moLecular analysis 2), were initially shared yesterday in a poster presentation at RISE UP for Breast Cancer. Twenty patients (10 pre- and nine postmenopausal women, and one male) were enrolled in the lasofoxifene arm of the study, during which early Ki67 suppression in premenopausal patients was seen in the absence of ovarian function suppression (OFS). Ki67 is a marker that measures how fast cancer cells are dividing. “Lasofoxifene continued to demonstrate a strong tolerability profile while showing promising Ki67 suppression in this Phase 2 study, supporting our plans to further explore its potential in the neoadjuvant setting,” said Dr. David Portman, Sermonix founder and chief executive officer. “We are currently studying lasofoxifene in the ELAINE-3 Phase 3 combination study with abemaciclib in the ESR1-mutated metastatic breast cancer setting. We are excited to see it continue to demonstrate broad potential while offering unique quality of life benefits for people confronted with breast cancer.” Patients were enrolled in the I-SPY 2 arm from March 2023 to May 2024. Median total days of treatment was 154 days. At the time of data analysis, three patients were still on treatment and two discontinued treatment due to physician or patient preference. Median Ki67 expression went from 10% at baseline (range 1.0-40%) to 4% (1.0-18.0%) at Week 3. At three weeks, Ki67 expression was suppressed to <10% in 14 out of 16 (88%) patients, and to <2.7% in 6 out of 16 (38%) patients. Adverse events (AEs) were all grade 1-2. Most common AEs include hot flushes (65%), constipation (40%), fatigue (40%) and nausea (25%). “The I-SPY 2 EOP provides a biomarker-rich platform to test novel endocrine agents in the neoadjuvant setting in a molecularly selected group of patients with tumors that are predicted to have little to no benefit from chemotherapy,” said Dr. Jo Chien, principal investigator of the sub-study. “Lasofoxifene has demonstrated significant activity based on early Ki67 suppression, not only in postmenopausal women, but also in 10 premenopausal women without concomitant ovarian function suppression, with baseline Ki67 of 12.5% (1.0-40.0%) going to 3.0% (1.0-15%) at Week 3. It is exciting to see that lasofoxifene is well-tolerated even in our youngest patients who are often most impacted by the debilitating side effects of current standard endocrine therapy options.” Quantum Leap partners with a consortium that includes the U.S. Food and Drug Administration (FDA), industry, patient advocates, philanthropic sponsors and clinicians from 41 major U.S. cancer research centers. About LasofoxifeneLasofoxifene is an investigational novel endocrine therapy in clinical development which has demonstrated robust target engagement as an ESR1 antagonist in the breast, particularly in the presence of ESR1 mutations. Lasofoxifene has demonstrated anti-tumor activity as monotherapy and in combination with a CDK4/6 inhibitor in Phase 2 studies and has unique tissue selectivity distinguishing it from other current and investigational endocrine therapies, with beneficial effects seen on vagina and bone in previous clinical studies. Lasofoxifene, which Sermonix licensed globally from Ligand Pharmaceuticals Inc., has been studied in previous comprehensive Phase 1-3 non-oncology clinical trials in more than 15,000 postmenopausal women worldwide. Lasofoxifene’s bioavailability and activity in mutations of the estrogen receptor could potentially hold promise for patients who have acquired endocrine resistance due to ESR1 mutations, a common finding in the metastatic setting and an area of high unmet medical need. Lasofoxifene’s novel activity in ESR1 mutations was discovered at Duke University and Sermonix has exclusive rights to develop and commercialize the product in this area. Lasofoxifene, a novel targeted and tissue selective oral endocrine therapy, could, if approved, play a critical role in the precision medicine treatment of advanced ER+ breast cancer.
