Gomekli Generic: When Will Generic Mirdametinib Be Available?
This page is aggregated from FDA records, court filings and company announcements. Coded and designed by Dr. Brian Staiger, PharmD, BCPS
Updated October 9, 2026 How we build our data
Gomekli Generic at a Glance
Four quick answers from FDA records and our estimate.
- When is the first generic expected? 2039 to 2040 A wide window 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? October 2044 23 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 mirdametinib is expected to be available between 2039 and 2040. None is for sale yet.
Why 2039 to 2040?
The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet. We rate it probable: more likely than not, but it can still move.
If Gomekli’s last patent runs to October 2044, how can a generic come sooner?
The 23 patents that run past the expected month, to October 2044 (11,066,358, 11,084,780, 11,453,641, 11,571,402 and 19 more), 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. Here, the companies are expected to settle on a 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. 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 Gomekli 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.

Gomekli’s Road to a Generic
Gomekli has had the market to itself since the FDA approved it in February 2025 (Springworks Therapeutics Inc). Its FDA protection (orphan drug) runs to February 2032. Its 23 listed patents run to October 2044.
The first generic of Gomekli is expected between 2039 and 2040.
Why that month: the patent fight is likely to end in an agreement that sets the launch. The terms are not public yet.
Why a Generic Can Come Before October 2044
The last listed patent runs to October 2044; 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.
Gomekli Patents and FDA Protections
Every patent and exclusivity the FDA Orange Book lists for Gomekli’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.

Who Is Lined Up to Make Generic Mirdametinib
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 Gomekli yet.
Approved by the FDA
Not yet. The FDA has not approved a generic mirdametinib. Final approval often comes close to the day a generic can be sold.
For Sale in Pharmacies
Not yet. No company lists a generic mirdametinib 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).
Gomekli 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 Gomekli, 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 Gomekli
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.
Medicare Part D Spending
What Medicare drug plans spent on Gomekli, before manufacturer rebates.
- $6.3M
- January to March 2026, the latest CMS has posted

What a Generic Gomekli Means for You
Nothing Changes Until It Is in Pharmacies
Until a generic is actually for sale, keep filling Gomekli 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 Gomekli”. 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 Gomekli
Is there a generic for Gomekli right now?
No. As of October 9, 2026 no generic mirdametinib is listed for sale in the FDA NDC Directory.
When will Gomekli go generic?
2039 to 2040 is the expected window, and that is probable but not certain. The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet. The last listed patent runs to October 2044; a court ruling or a settlement can bring a generic sooner.
Will generic mirdametinib be the same as Gomekli?
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 Gomekli?
Not yet. The FDA Orange Book lists no approved generic version of Gomekli.
When does the Gomekli patent expire?
The FDA Orange Book lists 23 patents for Gomekli; the last runs to October 2044. 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 window on this page (2039 to 2040) weighs all of that.
