TRENDING TOPICS EVIDENCE IN FOCUS: ADUCANUMAB-AVWA

BEHAVIORAL HEALTH CORNER: KETAMINE

The American Academy of Neurology (AAN) has published an Evidence in Focus report on the use of aducanumab-avwa (Aduhelm™) in symptomatic Alzheimer’s disease (AD). In June 2021, the FDA granted Accelerated Approval to the anti-amyloid therapy for treating patients with AD. Accelerated Approval was based on a surrogate endpoint of reduction in amyloid beta plaques. In July 2021, the indication for use was revised to specify that treatment should be initiated in patients with mild cognitive impairment or mild dementia stage of disease. The amyloid betadirected antibody is administered every 4 weeks as a weight-based 10 mg/kg IV infusion following titration. Although the agent targets neuropathologic changes seen in AD, it has not yet shown clinically significant decline in cognitive function.

The FDA has released an alert to HCPs on the potential risks of compounded ketamine nasal spray. From April 2011 to January 2022, five cases of psychiatric events (delusion, dissociation, hallucination, panic attack, abuse/misuse) were identified after use of compounded ketamine nasal spray. Although ketamine is not FDAapproved for treating any psychiatric disorders, the “S” form of ketamine (esketamine [Spravato®]) received FDA-approval in 2019 as a nasal spray formulation for certain adult patients with depression. Due to serious risks, esketamine carries a Boxed Warning and is only available through the Spravato REMS. The intent of the FDA’s alert is to raise awareness regarding the risks of compounded ketamine nasal spray for home use, especially because a safe and effective dosage regimen for psychiatric use has not been determined.

AAN identified four clinical studies: one Class I level evidence (low risk of bias) and three Class II level evidence (moderate risk of bias). The Class I study was an ascendingdose study and demonstrated that single doses of up to 30 mg/kg were safe and well tolerated. Although the 3 Class II studies showed that aducanumab-avwa reduced amyloid deposition compared to placebo based on brain PET at 1 year, data evaluating clinical efficacy were mixed depending on the dose and the endpoint. Compared to placebo, aducanumab-avwa showed no change or a slower decline in CDR Sum-of-Boxes score that was of uncertain clinical significance. Furthermore, the agent carries a Warning/Precaution for amyloid-related imaging abnormalities (ARIA) that were observed in about 40% of aducanumab-treated patients, compared with 10% of patients receiving placebo. The evidence report details the populations indicated for use compared to the patients enrolled in the clinical studies. There are no contraindications to use on the FDA-approved label but a number of exclusions in the clinical studies (e.g., bleeding disorders, past brain hemorrhage, antiplatelets other than daily aspirin). Other concerns covered in the report include infrastructure demand, as well as duration of therapy. Notably, CMS will announce its final coverage determination for aducanumab-avwa by April 11, 2022.

COVID-19: NOTABLE DEVELOPMENTS

2 | APRIL 2022

The FDA has authorized a second booster dose of either mRNA COVID-19 vaccine, Pfizer-Biontech or Moderna, for people ≥ 50 years old and certain immunocompromised individuals. The White House has announced the launch of a “One-Stop-Shop” website to find where to access vaccines, tests, treatments, and high-quality masks. The website also includes a tool to locate > 2,000 test-to-treat sites (e.g., pharmacy-based clinics) for outpatient testing and treatment. The CDC has added considerations for an 8-week interval between the primary doses of an mRNA vaccine for those 12 to 64 years old, especially for males 12 to 39 years old. The risk of myocarditis is higher for males this age and may be decreased by extending the interval between the first 2 doses. The FDA has revised the EUA for the pre-exposure prophylaxis combination of tixagevimab co-packaged with cilgavimab (Evusheld™) to update the initial dose to 300 mg IM of each component due to the potential for decreased activity against certain Omicron subvariants. Previously, the initial dose was 150 mg of each component; those who received this dose should receive an additional 150 mg dose of each component as soon as possible. Please refer to the COVID-19 disclaimer at the end of the publication.


DRUG INFORMATION

HAPPENINGS & HIGHLIGHTS • The FDA has approved Mylan’s first generic version of budesonide and formoterol fumarate dihydrate (AstraZeneca’s Symbicort®) inhalation aerosol. The product is indicated for treating asthma in patients ≥ 6 years old as well as for the maintenance treatment of airflow obstruction and decreasing exacerbations in patients with COPD, including chronic bronchitis and/or emphysema. The drug-device combination metered-dose inhaler will be marketed under the trade name Breyna™. It is dosed as 2 inhalations 2 times a day (about 12 hours apart). Breyna is expected to be available in 2 strengths: 160 mcg/4.5 mcg per actuation and 80 mcg/4.5 mcg per actuation. • Product labeling for pembrolizumab (Keytruda®) has been updated to withdraw the indication for use in the third-line gastric cancer setting. This indication was granted Accelerated Approval in 2017 as a single agent for treating patients with recurrent locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors express PD-L1, as determined by an FDA-approved test, with disease progression on or after ≥ 2 prior lines of therapy (including fluoropyrimidineand platinum-containing chemotherapy and, if appropriate, HER2/neu-targeted therapy). Withdrawal of this indication was announced in July 2021.

• The FDA has approved the first generic (drug cartridges only) of MDD’s Apokyn® (apomorphine HCl) from Sage Chemical. The drug cartridges are compatible with the Apokyn Pen (brand-name pen injector). Apomorphine is indicated for the acute, intermittent treatment of hypomobility, “off” episodes in patients with advanced Parkinson’s disease. • The agency has granted approval to the first generic version of Viiv’s Selzentry® (maraviroc) tablets from Hetero Labs. Product is available in 150 mg and 300 mg tablets and is indicated in combination with other antiretroviral agents for the treatment of only CCR5tropic HIV-1 infection in adult and pediatric patients ≥ 2 years old weighing ≥ 10 kg. • A generic version of Almirall’s topical acne agent, Veltin™ (clindamycin phosphate/tretinoin), has received FDA approval. The topical clindamycin phosphate/tretinoin gel, 1.2%/0.025%, is indicated for the treatment of acne vulgaris in patients ≥ 12 years old and is from Solaris. • Obinutuzumab (Gazyva®) has received a new dosing regimen allowing for administration as an approximately 90-minute infusion in patients with follicular lymphoma who have received 3 obinutuzumab administrations at the standard infusion rate and not experienced any grade 3 or greater infusion related reactions.

DRUG INFORMATION HAPPENINGS • The American College of Rheumatology has published updated guidelines on the treatment of juvenile idiopathic arthritis (JIA), including treatment strategies for oligoarthritis, temporomandibular joint arthritis, and systemic JIA. • The CDC has released the 2022 Adult Immunization Schedule for individuals ≥ 19 years old as well as the 2022 Child and Adolescent Immunization Schedule for those ≤ 18 years of age. • The FDA has released final guidance on voluntary recalls urging companies to be proactive and “recall ready.” • The FDA has published 3 final guidance documents, to industry, on advancing the development of cancer therapies. The FDA has also released the second in a series of 4 patient-focused drug development guidance documents.
