Arbor Pharmaceuticals Announces FDA Approval of First NDA
Atlanta, GA — Arbor Pharmaceuticals announced today that the U.S. Food and Drug Administration (FDA) has approved its New Drug Application (NDA) for Nymalize™ (nimodipine) oral solution. Nymalize was previously granted Orphan designation which provides seven years of market exclusivity. Nymalize is the first and only nimodipine oral solution indicated for the improvement of neurological outcome in adult patients with subarachnoid hemorrhage (SAH).
Prior to the approval of Nymalize, nimodipine was only available in gel capsule form. Since the product is commonly administered to patients through a nasogastric tube healthcare providers would extract the product from the gel capsule with a syringe. This has resulted in accidental administrations of nimodipine intravenously instead of via the intended enteral (oral) syringe.
In 2010, the FDA issued a “drug safety communication” to healthcare professionals titled “Nimodipine Oral Capsules: Medication Errors – IV Administration May Result in Death, Serious Harm.” In this communication they reported twenty-five intravenous nimodipine prescribing or administration errors and that four of the patients who mistakenly received nimodipine intravenously died and five had near-death events. The Institute for Safe Medication Practice reported an additional death due to improper nimodipine administration in February 2013.
Ed Schutter, President & CEO of Arbor stated, “I am pleased that Arbor’s first NDA approval has the potential to save lives by reducing the opportunity for hospital administration errors.To further ensure that we minimize the potential for administration error, each Nymalize unit dose cup will be packaged with an oral syringe. Nymalize adds to our growing portfolio of approved prescription products that can improve the lives of our patients.”
Dr. Laurence Downey, VP of Medical & Scientific Affairs added, “Approval of our first NDA is an important milestone in the evolution of Arbor Pharmaceuticals. This is the first of what we hope will be multiple NDA approvals over the next several years. I would like to thank and congratulate our team that worked on the Nymalize NDA.”
Arbor Pharmaceuticals will launch Nymalize in the next few months.
Nymalize (nimodipine) oral solution is indicated for the improvement of neurological outcome by reducing the incidence and severity of ischemic deficits in adult patients with SAH from ruptured intracranial berry aneurysms regardless of their post-ictus neurological condition (i.e., Hunt and Hess Grades I-V).
Important Safety Information About Nymalize
Blood pressure should be carefully monitored during treatment with Nymalize (nimodipine) oral solution. Nimodipine may increase the blood pressure lowering effect of concomitantly administered anti-hypertensives such as diuretics, beta-blockers, ACE inhibitors, angiotensin receptor blockers, other calcium channel blockers, α-adrenergic blockers, PDE5 inhibitors, and α-methyldopa.
Patients with cirrhosis are at a higher risk of adverse reactions and should be monitored closely and administered a lower dose.
Concomitant use of strong inhibitors of CYP3A4 with nimodipine should generally be avoided due to risk of significant hypotension.These include some macrolide antibiotics (e.g. clarithromycin, telithromycin), some HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, saquinavir), some HCV protease inhibitors (e.g., boceprevir, telaprevir), some azole antimycotics (e.g., ketoconazole, itraconazole, posaconazole, voriconazole), conivaptan, delaviridine, and nefazadone.
Concomitant use of strong CYP3A4 inducers (e.g. carbamazepine, phenobarbital, phenytoin, rifampin, St. John’s wort) and nimodipine should generally be avoided, as nimodipine plasma concentration and efficacy may be significantly reduced.
Nimodipine plasma concentration can also be increased in the presence of moderate and weak inhibitors of CYP3A4. If nimodipine is concomitantly administered with these drugs, blood pressure should be monitored, and a reduction of the nimodipine dose may be necessary.
Grapefruit juice inhibits CYP3A4. Ingestion of grapefruit/grapefruit juice is not recommended while taking nimodipine.
Moderate and weak inducers of CYP3A4 may also reduce the efficacy of nimodipine. Patients on these should be closely monitored for lack of effectiveness, and a nimodipine dosage increase may be required.
Common Adverse Reactions
Most common adverse reactions (incidence ≥ 1% and ≥1% placebo) were hypotension, headache, nausea, and bradycardia.
