Explains

PharmD, BCPS · Clinical pharmacist Updated

Generic danicopan is expected to be available in August 2038, about 12 years away. None is for sale yet.

Why August 2038?

It is when Voydeya’s patent 12,076,319 ends. That patent covers a way of using it, and once it ends, generics can go on sale as soon as the FDA approves them. We rate it probable: more likely than not, but it can still move.

Why hasn’t the FDA approved a generic yet?

That is normal before a launch. The FDA usually can’t give a generic its final approval while a patent or exclusivity still blocks it, so final approval often comes close to the day the generic can be sold. No company holds a “tentative” approval yet either (the FDA’s word for a generic that is ready but still blocked).

Will the generic cost less?

Usually, but no company is recorded as having applied to make one yet, and a single company usually brings only a modest drop. See the price pattern

What should I do now?

Keep taking Voydeya as prescribed. When a generic arrives, your pharmacy may switch you to it automatically, and it may look different. What a generic means for you

Our month is only an estimate based on available information, so we never name a day.

Voydeya’s Road to a Generic

Voydeya has had the market to itself since the FDA approved it in March 2024 (Alexion Pharmaceuticals Inc). Its FDA protection (orphan drug) runs to March 2031. Its 2 listed patents run to August 2038.

The first generic of Voydeya is expected in August 2038.

Why that month: patent 12,076,319, on a way of using it, ends then.

Brand alone on the market Since FDA approval, March 2024
New chemical entity Ends March 2029
Orphan drug Ends March 2031
Patent 9,796,741 Expires February 2035
Patent 12,076,319 Expires August 2038 The patent behind the expected month of generic availability
Brand alone on the market FDA exclusivity Patent on the active ingredient Patent on a use First generic expected Swipe the chart sideways to see every year.

Each bar runs from the brand’s approval to the day that protection ends. The green band is our projection for the first generic: a month, never a day, because legal dates move and a generic reaches shelves days to weeks after it is allowed.

Voydeya Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Voydeya’s own applications. A protection running past the expected month does not mean the date is wrong: a settlement or a court ruling can let a generic in before a patent ends, and a patent on one formulation or use does not block every generic.

The one that matters for a generic launch: patent 12,076,319, which ends in August 2038, the month the first generic is expected.

Who Is Lined Up to Make Generic Danicopan

Three steps stand between a brand and a generic you can buy: a company applies to the FDA, the FDA approves it, and the company starts selling it.

1

Applied to the FDA

No company is recorded as having applied to the FDA to make a generic Voydeya yet.

2

Approved by the FDA

Not yet. The FDA has not approved a generic danicopan. Final approval often comes close to the day a generic can be sold.

3

For Sale in Pharmacies

Not yet. No company lists a generic danicopan for sale with the FDA.

Sources: how many companies have applied, from court records and company announcements; approved generics from the FDA Orange Book; tentative approvals from Drugs@FDA; what is for sale from the FDA NDC Directory. The FDA does not disclose an application before it approves it (21 CFR 314.430).

Voydeya Price: What Pharmacies Pay and What Generics Usually Do

What a Generic Could Cost

How we estimate it. The national survey of what pharmacies pay (NADAC) has no recent price for Voydeya, so we cannot show dollars. Here is the FDA’s finding of how far the price pharmacies pay usually falls as generic companies join: about 31% with one company, 44% with two, 73% with four and over 95% with six or more (the typical drop for every drug whose first generic came out from 2015 to 2017).

Median prices pharmacies paid for the generic (invoice prices), compared with the brand’s price before generic entry, from FDA’s 2019 analysis “Generic Competition and Drug Prices”. At the manufacturer’s price FDA found steeper drops (about 39%, 54%, 79% and over 95%), the figures quoted elsewhere on this tracker. A typical pattern, not a price quote for this medicine.

What Medicare and Medicaid Spend on Voydeya

Big public spending is part of why generic makers line up for a medicine, and why its first generic matters beyond the pharmacy counter. Figures are before manufacturer rebates, which are confidential.

What CMS says it is used for: Danicopan is used to treat a certain blood disorder (paroxysmal nocturnal hemoglobinuria). This disorder causes your body's immune system to break down red blood cells, which results in anemia.

What a Generic Voydeya Means for You

Nothing Changes Until It Is in Pharmacies

Until a generic is actually for sale, keep filling Voydeya as usual. When one arrives, there is nothing you need to sign up for.

Your Pharmacy May Switch You Automatically

Every state lets pharmacists fill a brand-name prescription with an FDA-approved generic rated as equivalent to it, and about 19 states require them to, unless your prescriber writes “dispense as written” or “brand medically necessary” on the prescription. Some states ask the pharmacist to tell you, or to get your OK first. A study of every state’s law has the details.

It Will Probably Look Different

US trademark law does not let a generic look exactly like the brand, so the color, shape or markings usually change. The active ingredient, strength and form are the same. An “authorized generic,” made by or for the brand’s own company, can look identical. The FDA explains.

Your Insurance May Change Too

Once a lower-cost version is available, many insurance plans charge more for the brand, or stop covering it. Your plan’s drug list (formulary) says how.

Until a generic is on US pharmacy shelves, be careful with websites that offer “generic Voydeya”. The FDA warns that unlicensed online pharmacies sell counterfeit and unapproved medicines; its BeSafeRx page shows how to check a pharmacy.

Questions people ask about Voydeya

Is there a generic for Voydeya right now?

No. As of October 9, 2026 no generic danicopan is listed for sale in the FDA NDC Directory.

When will Voydeya go generic?

August 2038 is the expected month, and that is probable but not certain. It is when Voydeya’s patent 12,076,319 ends. That patent covers a way of using it, and once it ends, generics can go on sale as soon as the FDA approves them.

Will generic danicopan be the same as Voydeya?

Yes in the ways that matter: the same active ingredient, strength and form, with proof that it reaches your blood the same way. Inactive ingredients can differ, which is why some people notice a different look or taste.

How much will the generic cost?

Nobody can say for sure before launch. No company is recorded as having applied to the FDA to make one yet, and a single company usually brings only a modest drop.

Has the FDA approved a generic Voydeya?

Not yet. The FDA Orange Book lists no approved generic version of Voydeya.

When does the Voydeya patent expire?

The FDA Orange Book lists 2 patents for Voydeya; the last runs to August 2038. The one behind the expected month is patent 12,076,319, which ends in August 2038. A patent date is not the launch date: settlements and court rulings often bring a generic earlier, and FDA approval or a company’s own plans can make it later. The expected month on this page (August 2038) weighs all of that.
