Key Terms

marketing authorisation application, maa, niemann-pick disease type c, european medicines agency, +4 more

8 terms

marketing authorisation application regulatory

"Zevra remains on track with multiple regulatory milestones, including its Marketing Authorisation Application (MAA)..."

A marketing authorisation application is the formal package a drug or medical-device maker submits to a health regulator to get permission to sell a product. Think of it as an application for a sales license: regulators review safety, effectiveness and manufacturing quality before granting permission. Investors watch these submissions because approval unlocks revenue and reduces development risk, while rejection or delays can materially affect a company’s value and timeline.

maa regulatory

"including its Marketing Authorisation Application (MAA) for the evaluation of arimoclomol..."

MAA stands for Marketing Authorization Application, the formal request a drug developer files with regulators (commonly in the European Union) asking for permission to sell a medicine. Think of it like applying for a driver’s license for a product: approval means the company can market and earn revenue from the drug, while rejection or delays affect expected sales, timelines and the company’s valuation—so investors track MAAs as key risk/reward milestones.

niemann-pick disease type c medical

"for the treatment of Niemann-Pick disease type C (NPC), which is currently under review..."

A rare inherited disorder in which cells cannot move cholesterol and other fats properly, causing them to build up like a clogged waste line and leading to progressive neurological problems, liver dysfunction, and variable symptoms that can appear from infancy to adulthood. It matters to investors because effective treatments are limited, so drug candidates can attract strong regulatory incentives, premium pricing and focused patient populations, but clinical development is small, risky and uncertain.

european medicines agency regulatory

"currently under review by the European Medicines Agency."

The European Medicines Agency is the central drug regulator that evaluates and authorizes medicines for use across the European Union and related countries, similar to a referee or safety inspector who checks that a medicine is safe and effective before it can be sold. Its decisions matter to investors because approvals, rejections, or safety warnings directly affect a drug maker’s ability to sell products, generate revenue, and face legal or reputational risks, which in turn influence stock value.

phase 3 medical

"The Company is also conducting a Phase 3 trial of celiprolol for Vascular Ehlers-Danlos Syndrome..."

Phase 3 is the late-stage clinical testing step for a new drug or medical treatment, where the product is given to large groups of patients to confirm effectiveness, monitor side effects, and compare it to standard care. Successful Phase 3 results are often the final scientific hurdle before regulators decide on approval and market launch—like passing a final exam before graduation—and can sharply change a company's valuation and future revenue prospects.

vascular ehlers-danlos syndrome medical

"Phase 3 trial of celiprolol for Vascular Ehlers-Danlos Syndrome (VEDS)..."

A rare inherited disorder that weakens the body’s connective “scaffolding,” making arteries and organs more prone to tears or ruptures; think of it like faulty plumbing or wiring inside blood vessels that can burst unexpectedly. It matters to investors because it defines a specific patient population, creates urgent medical need for treatments or diagnostics, and influences the risk/reward for drug development, clinical trial design, regulatory approval, and healthcare costs.

u.s. food and drug administration regulatory

"preparing for further dialogue in the second half of 2026 with the U.S. Food and Drug Administration (FDA)..."

The U.S. Food and Drug Administration is the federal agency that evaluates and enforces safety, effectiveness and labeling standards for medicines, medical devices, vaccines, food and related products before they reach consumers. For investors it matters because FDA approvals, warnings or recalls determine whether a product can be sold, how quickly it reaches the market and how costly compliance will be—changes that directly affect a company’s revenue, costs and stock value.

fda regulatory

"with the U.S. Food and Drug Administration (FDA) to potentially accelerate the development program."

The FDA is the U.S. federal agency that evaluates and approves medical drugs, devices, biological therapies and certain foods; think of it as the gatekeeper that decides whether a medical product is safe and effective for patients. For investors, FDA decisions determine whether a company can sell a product, affect expected revenue and introduce regulatory risk, so approvals, rejections or safety warnings can quickly move a company's valuation and stock price.
