WHO defines essential medicines as those that satisfy the priority healthcare needs of the population. The drugs are selected based on disease burden, efficacy and safety data, and comparative cost-effectiveness.

The newly added oncology treatments are:

  • Opdivo® (nivolumab) as frontline monotherapy for the treatment of unresectable and metastatic melanoma
  • Velcade® (bortezomib), Revlimid® (lenalidomide), Thalomid® (thalidomide), and melphalan for newly diagnosed multiple myeloma in both the transplant-eligible and -ineligible setting
  • Tarceva® (erlotinib) for the frontline treatment of EGFR-mutated advanced non-small cell lung cancer (NSCLC; with Gilotrif® [afatinib])
  • Zytiga® (abiraterone) for metastatic castration-resistant prostate cancer
  • Trisenox® (arsenic) oral and intravenous formulations for acute promyelocytic leukemia
  • Oncaspar® (pegasparagase) for acute lymphocytic leukemia (ALL)

The experts also considered the following but did not recommend them for inclusion:

  • Nivolumab, pembrolizumab, and atezolizumab (Tecentriq®) for the treatment of NSCLC
  • Perjeta® (pertuzumab) for human epidermal growth factor receptor 2 (HER2)-positive breast cancer
  • Kadcyla® (trastuzumab) for HER2-positive breast cancer
  • Truxima® (subcutaneous rituximab) and trastuzumab

Several cancer-related diagnostic tests were also added, including:

  • Lactate dehydrogenase activity test, which is used for the prognosis and monitoring of hematologic malignancies and germ cell tumors
  • Estrogen and progesterone receptor tests, which are used for the diagnosis, prognosis, and treatment of breast cancer
  • Tyrosine protein kinase receptor or HER2 overexpression tests, which used for the diagnosis, prognosis, and treatment of breast cancer
  • Papanicolaou test, which is used for cervical cancer screening
  • Prostate-specific antigen test, which is used for the diagnosis and monitoring of prostate cancer
  • Fecal immunochemical test, which is used for colorectal cancer screening
  • Human chorionic gonadotrophin (hCG) plus betahCG, which is used for the diagnosis and surveillance of germ cell tumors and gestational trophoblastic disease
  • Alphafetoprotein immunoassay, which is used in conjunction with ultrasound for screening for hepatocellular carcinoma in high-risk individuals with liver cirrhosis and those who have a family history; it is also used for the staging and monitoring of germ cell tumors
  • Basic panel for immunohistochemical testing, which is used for the diagnosis of lymphoma, as well as for subclassification, prognosis, and treatment
  • Basic panel of immunohistochemical markers, which are used for the diagnosis of solid tumors
  • BCR-ABL1and ABL1 transcript tests, which are used for the diagnosis and monitoring of chronic myelocytic leukemia (CML) and CML variants (neutrophilic CML) and for the prognosis of ALL
  • Essential flow cytometry panel of antibodies for leukemia, which is used in the diagnosis of acute leukemias
