Pylarify Generic at a Glance
Four quick answers from FDA records and our estimate.
- When is the first generic expected? June 2034 About 7.5 years away Why then?
- Has the FDA approved a generic? Not yet None in the FDA’s records yet Why not yet?
- When does the last patent end? June 2037 6 patents listed with the FDA Why is a generic expected sooner?
- Can you buy a generic today? Not yet No company lists one for sale
Generic piflufolastat f 18 is expected to be available in June 2034, about 7.5 years away. None is for sale yet.
Why June 2034?
It is when Pylarify’s patent 8,778,305 ends. That patent covers the active ingredient, the product’s formulation and a way of using it, and once it ends, generics should be able to go on sale as soon as the FDA approves them. We rate it probable: more likely than not, but it can still move.
If Pylarify’s last patent runs to June 2037, how can a generic come sooner?
The 2 patents that run past the expected month, to June 2037 (10,947,197 and 11,851,407), cover the active ingredient, the product’s formulation and a way of using it. A generic can still come sooner if a court rules a patent invalid or not infringed, or if the companies settle on an earlier date. That is why the expected month comes before the last protection ends. See the road to a generic
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. A company may already hold a “tentative” approval, which this record does not show.
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 Pylarify 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.

Pylarify’s Road to a Generic
Pylarify has had the market to itself since the FDA approved it in May 2021 (Progenics Pharmaceuticals Inc). Its FDA protections on record ended by May 2026. Its 6 listed patents run to June 2037.
The first generic of Pylarify is expected in June 2034.
Why that month: patent 8,778,305, on the active ingredient, the product’s formulation and a way of using it, ends then. That is about 3 years before the last listed patent runs out, in June 2037.
Why a Generic Can Come Before June 2037
The last listed patent runs to June 2037; a court ruling or a settlement can bring a generic sooner. Dr. Brian explains
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. Sources: FDA Orange Book; the expected month from court records and company announcements.
Pylarify Patents and FDA Protections
Every patent and exclusivity the FDA Orange Book lists for Pylarify’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 8,778,305, which ends in September 2030; the first generic is expected after it, in June 2034, about 7.5 years away. Why the later ones may not hold it back

Who Is Lined Up to Make Generic Piflufolastat F 18
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.
Applied to the FDA
No company is recorded as having applied to the FDA to make a generic Pylarify yet.
Approved by the FDA
Not yet. The FDA has not approved a generic piflufolastat f 18. Final approval often comes close to the day a generic can be sold.
For Sale in Pharmacies
Not yet. No company lists a generic piflufolastat f 18 for sale with the FDA.
Sources: how many companies have applied, from court records and company announcements; approved generics from the FDA Orange Book; what is for sale from the FDA NDC Directory. The FDA does not disclose an application before it approves it (21 CFR 314.430).
Pylarify 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 Pylarify, 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 Pylarify
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.
Medicaid Prescriptions by Quarter
725 prescriptions in the four quarters to Q1 2026, $3.5M paid.

Pylarify NDC Codes and Packages
Each Pylarify package sold today has its own NDC, the product number printed on the box and on the pharmacy label. Open one to see that package’s details, what pharmacies pay for it and its patent timeline.
| NDC | Product | Package | Company |

What a Generic Pylarify Means for You
Nothing Changes Until It Is in Pharmacies
Until a generic is actually for sale, keep filling Pylarify 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 Pylarify”. 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 Pylarify
Is there a generic for Pylarify right now?
No. As of October 9, 2026 no generic piflufolastat f 18 is listed for sale in the FDA NDC Directory.
When will Pylarify go generic?
June 2034 is the expected month, and that is probable but not certain. It is when Pylarify’s patent 8,778,305 ends. That patent covers the active ingredient, the product’s formulation and a way of using it, and once it ends, generics should be able to go on sale as soon as the FDA approves them. The last listed patent runs to June 2037; a court ruling or a settlement can bring a generic sooner.
Will generic piflufolastat f 18 be the same as Pylarify?
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 Pylarify?
Not yet. The FDA Orange Book lists no approved generic version of Pylarify.
When does the Pylarify patent expire?
The FDA Orange Book lists 6 patents for Pylarify; the last runs to June 2037. The one behind the expected month is patent 8,778,305, which ends in September 2030. 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 (June 2034) weighs all of that.
