Medical Director, Clinical Development

The company is a clinical-stage biopharmaceutical company committed to transforming the standard of care and improving outcomes for patients living with breast cancer and beyond. With our transformation into a fully integrated oncology company well underway, it’s an exciting time to be part of Team the company.

Our lead product candidate, palazestrant, is a novel, orally available complete estrogen receptor antagonist (CERAN) and selective estrogen receptor degrader (SERD) currently in two pivotal Phase 3 clinical trials. We expect top-line data from OPERA-01, our ongoing Phase 3 trial of palazestrant as a monotherapy in patients with second- or third-line ER+/HER2- metastatic breast cancer (MBC), in Q1 2027 which, if positive, could lead to our first potential approval and commercial launch in 2028. OPERA-02, our Phase 3 trial of palazestrant in combination with ribociblib in patients with frontline ER+/HER2- MBC, is enrolling patients. Together with its mechanism of action, pharmacokinetic properties, and the potential to demonstrate activity in both ESR1 wild-type and mutant tumors, palazestrant could transform the metastatic breast cancer treatment paradigm and provide access to a $15 billion global market opportunity.

Our follow-on product candidate, OP-3136, is a potent KAT6 inhibitor with the potential to generate further value and meaningfully impact the metastatic breast cancer treatment landscape – particularly in combination with palazestrant. We recently presented encouraging Phase 1 monotherapy data from this program across multiple solid tumor types, are advancing patient enrollment in the ongoing combination arms in MBC, and expect to initiate a Phase 1 study of OP-3136 in combination with Bayer’s darolutamide in metastatic castration-resistant prostate cancer by the end of this year.

Aspiring to transform the metastatic treatment paradigm is an ambitious endeavor that requires a resolute approach to developing better therapies and passionate colleagues dedicated to helping the patients we serve feel better, longer. Team the company possesses a deep commitment to a shared purpose, the sustained pursuit of excellence, cultivating the courage required to advance our programs, the drive to succeed, and a collective capacity for adaptability through learning, growth, and evolution. We are a small group of nimble self-starters who bring consistency in our quest for the extraordinary every single day.

If you’re ready to be part of a tenacious, courageous, agile, and growing team, join us in making a profound impact, together – for our patients, for your career, and for what’s beyond.
