The breast cancer market is rapidly evolving and presents new commercial opportunities for drug developers. CDK4/6 inhibitors (Pfizer’s Ibrance, Novartis’s Kisqali, and Eli Lilly’s Verzenio / Verzenios / Virginio) are creating new dynamics in the metastatic HR-positive / HER2-negative treatment practice. In HER2-positive breast cancer, HER2-targeting drugs in development are forecast to enter the market, while sales of current HER2-targeting agents will be impacted as a result of competition, label expansions, biosimilar entries, and new trials leading to changes in treatment guidelines. Furthermore, the approval of PARP inhibitors (AstraZeneca’s Lynparza and Pfizer’s Talzenna), PD-1-targeting agents (Roche / Genentech / Chugai’s Tecentriq), PI3K inhibitors (Novartis’s Piqray), HER2-targeting agents (Daiichi Sankyo / AstraZeneca’s Enhertu and Seattle Genetics’ Tukysa), TROP2-targeting antibody-drug conjugates (Immunomedics’ Trodelvy), and the anticipated entry of other agents from these drug classes will diversify treatment options, especially for triple-negative breast cancer.

Author(s): Paul Wilcock, PhD; Alexandre Vo Dupuy (PhamD, MSc)

Since October 2015, Dr. Wilcock has been a Business Insights Analyst in the oncology team at Decision Resources Group. He has experience in various indications including metastatic malignant melanoma and renal cell carcinoma, and will have a major focus on gastric cancer going forward.
Previously, Dr. Wilcock was a Research Funding Manager at Cancer Research UK, where he developed a deep understanding of drug discovery, predominantly in the academic setting. He gained his doctorate from the University of Manchester where he utilized Systems Biology to explore the role of cell signaling and hypoxia in oral cancer.

Alexandre joined Decision Resources Group in 2017 as an Associate Epidemiologist. He holds a PharmD from Paris Descartes University as well as a Master in pharmacoepidemiology from the University of Bordeaux.
Prior to joining Decision Resources Group, he worked within the fields of Consulting and Real World Evidence, and as an intern within the Global Epidemiology department of one of the top pharmaceutical company. As an associate epidemiologist, Alexandre works across multiple disease areas estimating and forecasting incidence and prevalence, with a focus on cancer epidemiology.
