Fiscal Year 2018 was productive and exciting at the Center for Biologics Evaluation and Research (CBER). We continued to support the promise of 21st Century medicine, advancing science and technology in the service of public health.
One of the highlights of FY 2018 was the approval of two gene therapies: Luxturna, the first directly administered gene therapy for a specific genetic disorder, an inherited retinal disease, and Yescarta, a cell-based gene therapy for certain types of adult, large B-cell lymphoma. We also approved HEPLISAV-B, a Hepatitis B vaccine to prevent infection caused by all known subtypes of hepatitis B virus in adults 18 through 70 years of age, Shingrix, a vaccine for the prevention of shingles in adults 50 years of age and older, and Fluarix Quadrivalent, to prevent influenza disease in children as young as 6 months of age. In addition, CBER/FDA granted an Emergency Use Authorization to the Department of Defense to enable the use of Freeze-Dried Plasma to treat hemorrhage or coagulopathy of U.S. military personnel injured during military combat when plasma is not available or its use is not practical.
FDA’s ongoing contributions to controlling Zika virus included CBER’s approval of the cobas Zika Test and the Procleix Zika Virus Assay (Nucleic Acid Tests), the first donor screening tests for the direct detection of Zika Virus RNA in human plasma from individual donors.
The report below highlights these and other CBER accomplishments that reflect our responses to new and ongoing scientific and regulatory challenges, such as those posed by advanced therapies, emerging infectious diseases, and threats to the blood supply. It also reflects how we are carefully focusing our own research and stakeholder outreach so they support our efforts to meet those challenges. Just to highlight one aspect of stakeholder outreach undertaken this year, we launched the INTERACT program (CBER INitial Targeted Engagement for Regulatory Advice on CBER producTs). These meetings enable sponsors to obtain preliminary informal consultation with the Agency at an early stage of development prior to a pre-IND meeting.
Our successes this year also included meeting or exceeding the expectations of the Prescription Drug User Fee Act VI and the Medical Device User Fee Amendments, as detailed below. CBER also initiated or completed efforts on behalf of the 21st Century Cure Act, including patient experience in regulatory decision making, providing grants to research institutions, drafting guidances for regenerative medicine, and contributing to a guidance on antibacterial and antifungal drug development.
CBER is pleased to provide this report, which demonstrates the Center’s continuing dedication to our vision and our mission of meeting the challenge of improving public health, nationally and globally.

Advancing access to safe and effective products
CBER advanced public health in 2018 by achieving or exceeding expectations in its scientific and regulatory overview of new products. These achievements included the following accomplishments:
- All four standard schedule (non-priority) and one priority Biologic License Applications received in FY 2018 were under review and within the review-time goal at the close of FY 2018.
- CBER acted within the goal timelines for all 11 BLA PDUFA applications received in FY 2017, as of September 2018. Among the six applications with standard schedules, four were approved, one was in Complete Response status, and one was withdrawn; among five Priority schedule applications, three were approved, one was in Complete Response status, and one was withdrawn.
- CBER exceeded the FY 2018 goal of 95% approval for 510(k) submissions by issuing a decision on 100% of submissions received in the FY 2018 cohort within 90 FDA days, as of June 30, 2018.
- CBER exceeded the FY 2018 goal of 95% for the “within-90-FDA-days” approval of Real Time PMA Supplements by issuing a MDUFA decision on 100% of submissions received within that time limit, as of June 30, 2018.
- CBER exceeded the FY 2018 goal of 95% approval of PMA 180-day supplements by issuing a MDUFA decision on 100% of submissions within that time limit.
- CBER completed its coordination of the Innovation Fund as required by the 21st Century Cures Act, and invested $14 million of its resources by the end of FY 2018. As part of our commitment to achieving the goals of the 21st Century Cures Act, CBER awarded nearly $3 million in grants to support research at five institutions aimed at developing more innovative, consistent, and dependable manufacturing of biological products.
- CBER assessed regulatory agencies of 14 countries to ensure their inspection of medical products regulated by the Center could be recognized by the FDA, as per required by the MRA. CBER continued to assess the remaining European Union member states to meet December 2018 and July 2019 commitments.
- CBER/FDA granted an EUA to the Department of Defense (DoD) to enable the emergency use of Pathogen-Reduced Leucocyte-Depleted Freeze-Dried Plasma manufactured by the Centre de Transfusion Sanguine des Armées (French FDP). The product is used to treat hemorrhage or coagulopathy of U.S. Military personnel injured during military combat when plasma is not available or its use is not practical. The granting of the EUA demonstrates FDA’s commitment to the joint program that was started in FY 2018 to further enhance FDA’s support of DoD to ensure the efficient development of medical products to treat injured military personnel, focusing first on products regulated by CBER.
Approval of major, innovative, complex biologic products
FY 2018 was a productive year for approvals of novel biologic products, especially cell and gene therapies. CBER also approved new vaccines and continued to approve blood screening devices for emerging infections. The introduction of these products reflect the commitment of CBER scientists to support the development of products made using advanced and novel technologies.

- FDA research to improve technique for studying multipotent stromal cell morphology
Demonstration of unexpected changes in the morphology (shape and size) of multipotent stromal cells (MSCs) have been documented when preparations of the cells interact with specific engineered culture systems. The finding is a step toward understanding how to accurately interpret studies that use such systems, called microfluidics platforms, so they can support the development of safe and effective medical products based on multipotent stromal cells.
- Results of FDA study support development of high throughput sequencing for viral safety evaluation of biologic materials
The findings of a study led by CBER scientists suggest that a highly sensitive, but complex, new technology to sequence the genetic material of viruses could be standardized and used for rapid screening of biologic products, including vaccines, to demonstrate absence of contamination. The results of the study support the development of standard reference virus reagents that can be used to validate the performance of their high throughput screening procedures to demonstrate absence of viral contamination for product safety.
- Universal influenza vaccine candidate reduces transmission of virus best when given nasally in mice
FDA scientists demonstrated the ability of their universal influenza vaccine candidate to reduce the transmission of influenza virus in mice, even though this vaccine does not completely block infection by the virus. The FDA findings are important because they suggest the vaccine could both help protect recipients and reduce transmission, even when virus strains emerge with differing envelope proteins -- a type of change, that when it occurs, can make existing influenza vaccines less effective.
- Malaria gene activity findings could form basis of improved test for monitoring disease spread
Scientists at the U.S. Food and Drug Administration (FDA), in collaboration with the Johns Hopkins Malaria Research Institute, identified changes in the expression of specific genes of human malaria parasite Plasmodium falciparum as they undergo development in the mosquito midgut. These newly identified genes and antigens could become the basis of an improved test for monitoring the disease burden in countries where malaria is transmitted.
