Industry News: FDA Finalizes Historic Rule Enabling Access to Over-the-Counter Hearing Aids for Millions of Americans

The FDA issued a final rule to improve access to hearing aids which may in turn lower costs for millions of Americans. This action establishes a new category of over-the-counter (OTC) hearing aids, enabling consumers with perceived mild to moderate hearing impairment to purchase hearing aids directly from stores or online retailers without the need for a medical exam, prescription or a fitting adjustment by an audiologist.

Consumer Warning for Erectile Dysfunction Pills

The FDA confirmed that consumers have received these drugs, without a prescription, which contain 100 mg of sildenafil, the active ingredient in Viagra. This is a dangerous dosage strength for certain patients including the elderly and those with impaired liver and kidney function. When sildenafil interacts with nitrates in some prescription drugs, such as nitroglycerin, a person’s blood pressure can reach dangerously low levels. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.

Do not use these products. If you have used these products and became ill or otherwise experienced an adverse event, contact your health care provider. FDA continues to warn consumers that medications purchased from unapproved and/or unlicensed sources may be dangerous as they can be counterfeit, contaminated, improperly stored and transported, ineffective, and/or unsafe.

The label on the blister packs for these unapproved drugs states that the products are manufactured in India by Acme Generics. The label also bears the name Sun Pharma. FDA is concerned the seller may also be distributing to U.S. consumers unapproved tadalafil as a generic for the prescription drug Cialis.

Adverse Events
To date, FDA is not aware of any adverse events associated with these particular unapproved versions of sildenafil or tadalifil. Health care professionals and consumers should report any adverse events related to this product to FDA’s MedWatch. Adverse Event Reporting program by:
•  Completing and submitting the report online at MedWatch Online Voluntary Reporting Form
•  Downloading and completing the form, then submitting it via fax at 1-800-FDA-0178.

3D Printing for Medical Devices

3D printing is a process that creates a three-dimensional object by building successive layers of raw material.

Objects are produced from a digital 3D file, such as a computer-aided design (CAD) drawing or a Magnetic Resonance Image (MRI).  The flexibility of 3D printing allows designers to make changes easily without the need to set up additional equipment or tools. It also enables manufacturers to create devices matched to a patient’s anatomy (patient-specific devices) or devices with very complex internal structures. These capabilities have sparked huge interest in 3D printing of medical devices and other products, including food, household items, and automotive parts.

In the picture, models have been 3D-printed for (left to right, top) a brain, blood vessel, surgical guide, and (bottom) medallion printed on FDA 3D printers.

Medical devices produced by 3D printing include orthopedic and cranial implants, surgical instruments, dental restorations such as crowns, and external prosthetics. Due to its versatility, 3D printing has medical applications in:
• Medical devices – regulated by FDA’s Center for Devices and Radiological Health (CDRH)
• Biologics – regulated by FDA’s Center for Biologics Evaluation and Research
• Drugs – regulated by FDA’s Center for Drug Evaluation and Research

Medical device manufacturers should refer to FDA guidance documents and Quality Systems regulations for more information on specific applications.

Working to Bridge Gaps in Rare Disease Product Development

There are approximately 7,000 rare diseases affecting an estimated 30 million people in the United States. Many
of these diseases are serious or life-threatening and it is estimated that half affect children. Unfortunately, most rare diseases still do not have approved therapies.  In 2018 we saw a record number of novel drugs and biologics approved for rare diseases. In particular, there were 35 novel drugs and biologics approved in 2018 with orphan drug designation. This is the highest number since the passage of the Orphan Drug Act in 1983.

These approvals included drugs and biologics utilizing programs to facilitate and expedite development and review of medical products to address unmet medical need. Among the many new orphan therapies in 2018, the FDA approved the first drug to treat patients with a rare, inherited form of rickets, and the first orally-administered drug to treat Fabry disease. The FDA also approved a new biologic for patients when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding.

The FDA will host a public meeting on April 29, 2019: ”Patient Perspectives of the Impact of Rare Diseases: Bridging the Commonalities.” This provides the opportunity to hear patients’ and caregivers’ perspectives on how rare diseases impact their daily lives and to assess commonalities that may help the Agency and medical product developers further understand and advance the development of treatments for rare diseases. While the differences between rare diseases are critically important, it is also important to assess commonalities to synergize product development in rare diseases.

Additionally the grant review process will be enhanced by providing grant reviewers with patient perspectives gleaned from listening sessions with patients about rare diseases. These enhancements will build on new priorities in grant review. Specifically, to address the unmet needs for rare diseases, the Office of Orphan Products has made meaningful changes to both funding focus and review process for the Clinical Trial and Natural History grants programs. They are focusing on studies of rare diseases with unmet needs that use efficient and innovative trial designs, such as adaptive and seamless trial designs, use of modeling and simulations, incorporation of real world data, and basket and umbrella trials studying multiple rare diseases/products. Applicants are asked to incorporate patient input into their research proposals.

Hong Kong Dept of Health Approves Biktarvy® for HIV, following FDA and EC

In Phase 3 Clinical Trials, Biktarvy® Demonstrated High Efficacy and Zero Resistance Through 48 Weeks

The triple-combination, single-tablet therapy combines the potency of the novel integrase strand transfer inhibitor (INSTI) bictegravir, with the demonstrated safety and efficacy profile of a guideline recommended dual nucleoside reverse transcriptase inhibitor (NRTI) backbone – Descovy® (emtricitabine 200 mg/tenofovir alafenamide 25 mg; FTC/TAF). BIC/FTC/TAF provides a convenient once-daily dosing STR without regards to food. Furthermore, BIC/FTC/TAF’s use is not restricted by the patient’s baseline viral load, CD4 cell count or HLA-B 5701 status.

“Safety and resistance profiles are important considerations for HIV patients, as the disease requires long-term care. In addition, potent treatments with convenient dosing can potentially improve adherence and outcomes for patients,” said Dr Chan Kai Ming, Specialist in Infectious Disease, Consultant in Internal Medicine, Union Hospital, Hong Kong.

The Hong Kong Dept of Health has approved Biktarvy® (bictegravir 50mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg; BIC/FTC/TAF), a once-daily single tablet regimen (STR) for the treatment of HIV-1 infection in adults*. Hong Kong is the first market in Asia to approve Biktarvy. BIC/FTC/TAF was approved by the U.S. Food and Drug Administration (FDA) on February 7, 2018 and the European Commission on June 21, 2018.

The approval was based upon data from four ongoing Phase 3 studies: Studies 1489 and 1490 in treatment-naive HIV-1 infected adults, and Studies 1844 and 1878 in virologically suppressed adults. The trials are comprised of a population of 2,414 participants, and BIC/FTC/TAF met its primary efficacy objective at 48 weeks in all four studies, with no participants in any of the four BIC/FTC/TAF studies developing treatment-emergent virologic resistance. There were no cases of renal discontinuation, proximal renal tubulopathy or Fanconi syndrome in the BIC/FTC/TAF arms at 48 weeks. Additional ongoing studies not included in the marketing authorization application involve dedicated studies in women, adolescents and children.

“We welcome the timely approval of BIC/FTC/TAF in Hong Kong, a novel treatment option for people living with HIV,” said Andrew Hexter, Vice President and GM for Gilead Sciences Asia. “We are committed to serving the needs of HIV patients and medical communities in Asia, and are working with public health authorities to make the treatment available in this region.”
