Linical Accelovance Group, a mid-size global contract research organization, will serve as Sermonix’s research partner for the study, enrolling 100 patients in 27 sites across the U.S.
“Sermonix selected Linical Accelovance to be our clinical research development partner for this program because we are impressed with the organization’s integrated clinical trial services, as well as its operational capabilities in the development of oncology drugs,” said Sermonix Chief Operating Officer Dr. Miriam Portman.
The trial will utilize oral lasofoxifene for advanced breast cancer patients with ESR1 gene mutations. The primary clinical endpoint will be progression-free survival (PFS).
Sermonix is developing lasofoxifene as a precision medicine treatment for patients with ER+ metastatic breast cancer that has progressed after endocrine therapy.
“Lasofoxifene has significant safety and tolerability data from previous Phase 1 through Phase 3 studies in over 15,000 postmenopausal women in non-oncologic conditions,” said Dr. David Portman, founder and chief executive officer of Sermonix. “We look forward to working with Linical Accelovance on our Phase 2 trial and in the development of oral lasofoxifene as a potential precision medicine therapy for patients with endocrine resistance and ESR1 mutations.”
Lasofoxifene is an investigational, nonsteroidal selective estrogen receptor modulator (SERM), which Sermonix licensed from Ligand Pharmaceuticals Inc. (NASDAQ: LGND). Lasofoxifene has been studied in comprehensive non-oncology clinical trials recruiting more than 15,000 women worldwide and has demonstrated efficacy for treating vulvovaginal atrophy (VVA) and postmenopausal osteoporosis.
Oral Lasofoxifene’s binding affinity and activity in mutations of the estrogen receptor may hold promise for patients who have acquired resistance and mutations of the estrogen receptor, a common mutation in the metastatic setting and an area of high unmet medical need. Lasofoxifene’s novel activity in ESR1 mutations has recently been discovered and Sermonix has exclusive rights to develop and commercialize oral lasofoxifene in this area.
Oral Lasofoxifene, a potent, well-tolerated and bioavailable SERM, if approved could play a critical role in the personalized treatment of advanced ER+ breast cancer.
