Breast cancer: a front-runner when it comes to the development of novel therapeutic strategies. With the advent of newer targeted- and immunotherapies, oncologists have an increment of options to offer their patients. The American Society of Clinical Oncology’s (ASCO) 2019 Breast Cancer track offered an extensive look at the latest advancements and updates from on-going trials covering the various subtypes of breast cancer.
Immunotherapy with programmed death 1 (PD-1) antibody pembrolizumab led to an objective response rate (ORR) of 14.6% in previously treated advanced cervical cancer patients with PD-L1–positive disease, as reported by Chung et al. on behalf of the KEYNOTE-158 investigators in the Journal of Clinical Oncology.
Combining programmed death 1 ligand (PD-L1) inhibitor atezolizumab with MEK-inhibitor cobimetinib in patients with previously treated metastatic colorectal cancer (mCRC) does not improve the overall survival (OS) when compared to regorafenib, as was reported by the investigators of the IMblaze370 (NCT02788279) trial in the Lancet Oncology.
On 19 December 2018, the FDA approved olaparib (Lynparza®, AstraZeneca) as a maintenance treatment for adult advanced epithelial ovarian, fallopian tube or primary peritoneal cancer patients who achieving a complete or partial response to first-line platinum-based chemotherapy and who have deleterious germline or somatic BRCA-mutatations (gBRCAm or sBRCAm) by an FDA-aproved test or who are suspected to have deleterious BRCA-mutatations (BRCAm).
Adding ipilimumab (IPI [Yervoy®, Bristol-Myers Squibb]) to nivolumab (NIVO [Opdivo®, Bristol-Myers Squibb]) induction followed by maintenance with single-agent NIVO had a superior objective tumour response rate and progression-free survival (PFS) when compared to NIVO alone in patients with persistent or recurrent epithelial ovarian cancer.

- FDA approved Fulphila (pegfilgrastim-jmdb, Mylan GmbH), a biosimilar of Neulasta (pegfilgrastim, Amgen, Inc.) to decrease the chance of infection due to febrile neutropenia in patients receiving myelosuppressive chemotherapy with clinically significant incidence of febrile neutropenia and with non-myeloid cancers.
On May 18, the United States (US) Food and Drug Administration (FDA) issued an alert about the decreased survival in studies with pembrolizumab (Keytruda®) and atezolizumab (Tecentriq®) as single agent first-line therapy for patients with metastatic urothelial cancer (mUCC) and low expression of the programmed death ligand 1 (PD-L1) protein.
- On May 14, 2018 the FDA announced approval of biosimilar epoetin alfa-epbx (Retacrit®, Hospira, a subsidiary of Pfizer) for the treatment of anemia due to chronic kidney disease (CKD) in patients on dialysis and not on dialysis, use of zidovudine in patients with HIV infection, and the effects of concomitant myelosuppressive chemotherapy. Epoetin alfa-epbx is also approved for the reduction of allogeneic red blood cell transfusions in patients undergoing elective, noncardiac, nonvascular surgery. Retacrit® is a biosimilar of Epogen/Procrit (epoetin alfa, Amgen).
First-line atezolizumab plus bevacizumab, carboplatin and paclitaxel improves PFS in patients with non-squamous NSCLC. Two presentations on the IMPower150 study by Martin Reck (ELCC 2018) and Mark Socinski (AACR 2018) discussed the frontline addition of atezolizumab to bevacizumab and chemotherapy in different lung cancer subgroups (NCT02366143).
AACR 2018: Frontline pembrolizumab plus chemotherapy in NSCLC reduces the risk of death by more than 50%. The Phase III KEYNOTE-189 trial combined pembrolizumab (Keytruda®) plus standard of care platinum-based chemotherapy in non-squamous non–small cell lung cancer (NSCLC) without EGFR or ALK genetic aberrations (NCT0278680)
