FDA, CDC, and NIH Co-sponsored Public Workshop Summary-Development Considerations of Antimicrobial Drugs for the Treatment of Gonorrhea.

There is an unmet need for developing drugs for the treatment of gonorrhea, due to rapidly evolving resistance of Neisseria gonorrhoeae against antimicrobial drugs used for empiric therapy, an increase in globally reported multidrug resistant cases, and the limited available therapeutic options. Furthermore, few drugs are under development. Development of antimicrobials is hampered by challenges in clinical trial design, limitations of available diagnostics, changes in and varying standards of care, lack of robust animal models, and clinically relevant pharmacodynamic targets.

Food and Drug Administration Public Workshop Summary-Development Considerations of Antifungal Drugs to Address Unmet Medical Need.

Pressing challenges in the treatment of invasive fungal infections (IFIs) include emerging and rare pathogens, resistant/refractory infections, and antifungal armamentarium limited by toxicity, drug-drug interactions, and lack of oral formulations. Development of new antifungal drugs is hampered by the limitations of the available diagnostics, clinical trial endpoints, prolonged trial duration, difficulties in patient recruitment, including subpopulations (eg, pediatrics), and heterogeneity of the IFIs. On 4 August 2020, the US Food and Drug Administration convened a workshop that included IFI experts from academia, industry, and other government agencies to discuss the IFI landscape, unmet need, and potential strategies to facilitate the development of antifungal drugs for treatment and prophylaxis.

Geographic Shifts in Antibacterial Drug Clinical Trial Enrollment: Implications for Generalizability.

Background: As drug development has globalized, trials have increasingly enrolled participants from all parts of the world rather than just the United States and Western Europe. For antibacterial drug trials, understanding enrollment trends and regional differences is important for generalizability considerations.

Methods: We retrospectively analyzed 42 phase 3 trials submitted to the US Food and Drug Administration after 2001 for complicated urinary tract infection (cUTI), complicated intra-abdominal infection (cIAI), community-acquired bacterial pneumonia (CABP), and acute bacterial skin and skin structure infection (ABSSSI) (n = 29 282 participants).

Use of biomarkers to improve immunosuppressive drug development and outcomes in renal organ transplantation: A meeting report.

On September 27-28, 2018 the Food and Drug Administration (FDA) and the Critical Path Institute's Transplant Therapeutics Consortium convened a public workshop titled "Evidence-Based Treatment Decisions in Transplantation: The Right Dose & Regimen for the Right Patient/Individualized Treatment." The workshop facilitated cooperative engagement of transplant community stakeholders, including pharmaceutical industry, academic researchers, clinicians, patients, and regulators to discuss methods to advance the development of novel immunosuppressive drugs for use in solid organ transplantation. Day 1 focused on the utility of biomarkers in drug development with considerations for seeking regulatory endorsement for use in clinical trials.

Summary of 2017 FDA Public Workshop: Antibody-mediated Rejection in Kidney Transplantation.

Despite major advances in understanding the pathophysiology of antibody-mediated rejection (AMR); prevention, diagnosis and treatment remain unmet medical needs. It appears that early T cell-mediated rejection, de novo donor-specific antibody (dnDSA) formation and AMR result from patient or physician initiated suboptimal immunosuppression, and represent landmarks in an ongoing process rather than separate events. On April 12 and 13, 2017, the Food and Drug Administration sponsored a public workshop on AMR in kidney transplantation to discuss new advances, importance of immunosuppressive medication nonadherence in dnDSA formation, associations between AMR, cellular rejection, changes in glomerular filtration rate, and challenges of clinical trial design for the prevention and treatment of AMR.

Population mobility, globalization, and antimicrobial drug resistance.

Population mobility is a main factor in globalization of public health threats and risks, specifically distribution of antimicrobial drug-resistant organisms. Drug resistance is a major risk in healthcare settings and is emerging as a problem in community-acquired infections. Traditional health policy approaches have focused on diseases of global public health significance such as tuberculosis, yellow fever, and cholera; however, new diseases and resistant organisms challenge existing approaches.

Clinical relevance of preclinical testing for allergic side effects.

Immune-mediated hypersensitivity reactions include exaggerated humoral or cell mediated responses to specific antigens and may culminate in adverse, potentially life threatening effects. The immune status of the host and presence of infections or other disorders can alter the kind and extent of immune mediated side effects in individuals. Such variability in the immune status may influence the type of idiosyncratic reaction(s) that patients manifest.
