Medical Science Liaison/Sr. Medical Science Liaison – West


Partner Therapeutics (PTx) is devoted to developing and commercializing cancer medicines and combination therapies that can make a meaningful difference in the lives of cancer patients.  We are united in our passion for improving the treatment of cancer and our desire to make a meaningful contribution to outcomes.  We believe that being a cancer company begins and ends with the patient.  We strive to support patients throughout their treatment journey and offer therapy options that are right for them and their loved ones.


PTx has acquired worldwide rights to Leukine® (sargramostim).  As the only FDA approved GM-CSF available in the U.S., we believe Leukine offers important and differentiated benefits to cancer patients and are excited by the opportunity to effectively re-introduce it to the oncology community with its current label and future expansion indications.  Despite no commercial support for over a decade, Leukine is currently used in academic centers and group practices throughout the country.  There is significant scientific interest in Leukine with over 100 ongoing ISTs.


We are looking for a small number of highly motivated, experienced medical science liaisons (MSLs) with a proven track record of successfully engaging healthcare professionals to build the company’s first field team.  Our goal is to ensure all stakeholders have the data and information they need to make the best possible decisions for their patients in need of colony stimulating factor (CSF) therapy.  The MSLs will report to the Sr. Director of Medical Affairs.
