FDA Guidance for New Antibacterial Treatment
● The development of new antibacterial treatments has been challenging, and relatively few companies are actively working in this area. To support the development of these vital drugs, the FDA has released a new guidance document titled: Antibacterial Therapies for Patients with an Unmet Medical Need for the Treatment of Serious Bacterial Diseases- Questions and Answers.
“Given the urgent need for development of new antibacterial drugs to treat serious bacterial diseases, FDA intends to apply appropriate regulatory flexibility with regard to meeting the requirements for substantial evidence of effectiveness in such situations, as stated in 21 CFR part 312, subpart E (Drugs Intended to Treat Life-threatening and Severely-debilitating Illnesses): [1]
The Food and Drug Administration (FDA) has determined that it is appropriate to exercise the broadest flexibility in applying the statutory standards, while preserving appropriate guarantees for safety and effectiveness. These procedures reflect the recognition that physicians and patients are generally willing to accept greater risks or side effects from products that treat life-threatening and severely debilitating illnesses, than they would accept from products that treat less serious illnesses. These procedures also reflect the recognition that the benefits of the drug need to be evaluated in light of the severity of the disease being treated and the availability of treatment options.[2]”
● The use of the FDA 510 Pathway is sometimes problematic when selecting a predicate device, especially if the device is to be used in a different organ. The proposed device must have the same intended use, technological characteristics, performance testing, labeling (must not introduce new intended uses or misleading claims), and must not raise new safety or effectiveness questions as the predicate device.[3] o An experienced consultant who understands the detailed regulations and has knowledge in dealing with the device division of the FDA is highly effective in navigating the regulatory approval process. Examples of such companies are Facet Life Sciences (Wayne, PA), regulanet® (Germany), QNova Life Sciences (Columbia, MD) and MedSurgPI (Research Triangle Park, NC).
Assessing Causality for SAEs
● Occam’s Razor is a problem-solving principle that states the simplest explanation for a phenomenon is usually the correct one. Applying this principle when assessing causality for a serious adverse event in complex oncology or cell and gene therapy trials, particularly those involving multiple concomitant therapies (chemotherapies, hormone therapy, checkpoint inhibitors) alongside investigational products, it is prudent to prioritize the most plausible causative agents with known associations to the event. If causality relationships remain undefined after the more plausible relationships have been explored without yielding a determination, wider exploration is warranted. Speculative attribution to products lacking supporting evidence from preclinical, clinical, or real-world data should be avoided.[4]
Medical Affairs
AI for Real World Evidence
● Artificial Intelligence (AI) is being employed more and more to gather and analyze real-world data and registry data to create real-world evidence.[5] Together with clinical trial results, AI can help identify gaps in existing evidence and prioritize research questions that support new evidence-generation opportunities. These insights can be produced more efficiently and cost-effectively versus when traditional manual approaches are used alone.[6]
Post-Marketing Safety Data
● Medical Affairs teams can be instrumental in obtaining important post-marketing safety data. They may discover evidence of unreported adverse events in the following:
o Scientific exchanges with clinicians and their staff[7] o Literature reviews o Webinars o Panel discussions o Conference attendance o Registries o Real-world data o Post-marketing studies.[8]
The number of adverse events, by type/category as well as the overall volume, which occur after a product is launched, is known to be significantly under-reported. The use of medical record data mining coupled with medical affairs directed AI analysis of the medical literature can significantly improve the detection of unreported serious adverse drug reactions.[9]
Ideas for Medical Journals
● Medical journals are continually evolving in their content, coverage, and influence on healthcare. We believe that their contributions could be further enhanced by incorporating new dimensions into their offerings. The following are seven suggestions to increase the relevance and utility of medical journals in today’s healthcare landscape:
1. Encourage greater interactivity by publishing moderated comment sections on important issues. For example, the distinction between antihypertensive drugs found to be efficacious in controlled trials versus those proven to be more effective in real-world settings.
2. Articles discussing diagnostic innovations, emerging therapeutic trends, and results from early-phase studies.
3. Nutritional aspects of the treatment plan such as improving the nutritional status of oncology patients before and during therapy.
4. Practical diagnostic and therapeutic paradigms, such as the use of remote patient monitoring (RPM) and telehealth, to prevent severe respiratory exacerbations that may otherwise require emergency department visits or hospitalization.
5. Publication of medical tips or practical pointers to improve patient care. For example, “Allergy Tips of the Month” was successfully published in the now-defunct journal Immunology and Allergy Practice. Similar tips are published today in the American Academy of Allergy, Asthma & Immunology (AAAAI) journal. These brief, actionable insights provide readers with practical ideas that can be readily applied in clinical practice.
6. Journals should encourage more people to contribute articles, case histories, case series, reviews, etc. by offering shorter review timelines and reduced publication fees. More professionals across healthcare should be encouraged to write, read, and review scientific articles, thereby expanding the impact and utility of medical journals.
7. The lack of negative results in the scientific literature can create a biased view of the scientific landscape. This can potentially lead to flawed conclusions and to others repeating a clinical study, which can actually harm patients, or not help them. Journal editors need to encourage and publish negative results.
8. Finally, patient advocates and advocacy groups should be invited to participate or submit publications or author editorials to provide the patient’s perspective.
