Why two NDCs? The FDA registers this code as 84577-751-01 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 84577-0751-01. Same drug, same package — only the format differs.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

Patents & exclusivity — FDA Orange Book

2026 2028 2030
Today
LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of this drug?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for this drug. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Jul 2031 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 84577-751-01, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 84577-0751-01, written without dashes as 84577075101. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 84577-0751-01, the first segment (84577) is the labeler code FDA assigned to Celcuity Inc.; the middle segment (0751) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Celcuity Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Celcuity Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

Refer to the Prescribing Information of palbociclib and fulvestrant for pregnancy and contraception information. ( 5.4 , 8.1 , 8.3 )

5.1Stomatitis REVTORPYK can cause severe stomatitis, including ulcers and oral mucositis. In Study 1 of VIKTORIA-1, stomatitis occurred in 72% of patients treated with REVTORPYK with fulvestrant and palbociclib, including Grade 3 events in 22% of patients. Prophylactic steroid-containing alcohol-free mouthwash was required for a minimum of 8 weeks.

The median time to onset was 7 days (range: 1 to 457 days). Stomatitis led to REVTORPYK dose reduction in 19% and permanent discontinuation in 3.8% of patients. Stomatitis occurred in 58% of patients treated with REVTORPYK with fulvestrant, including Grade 3 events in 12% of patients.

The median time to onset was 4 days (range: 1 to 524 days). Stomatitis led to REVTORPYK dose reduction in 9% and permanent discontinuation in 1.5% of patients. Prophylactically initiate steroid-containing alcohol-free mouthwash to reduce the incidence and severity of stomatitis [see Dosage and Administration (2.3) ] .

If stomatitis occurs, increase the frequency of mouthwash and administer other topical treatments as clinically indicated. Withhold, reduce dose, or permanently discontinue REVTORPYK based on severity [see Dosage and Administration (2.4) ] .

5.2Dermatologic Adverse Reactions REVTORPYK can cause severe rash. In Study 1 of VIKTORIA-1, rash occurred in 30% of patients treated with REVTORPYK in combination with fulvestrant and palbociclib, including Grade 3 events in 6% of patients. The median time to onset was 21 days (range: 3 to 260 days) after starting REVTORPYK.

Rash led to REVTORPYK dose reduction in 5% and permanent discontinuation in 0.8% of patients. Rash occurred in 40% of patients treated with REVTORPYK in combination with fulvestrant, including Grade 3 events in 5% of patients. Rash led to REVTORPYK dose reduction in 6% and permanent discontinuation in 0.8% of patients.

The median time to onset was 31.5 days (range: 2 to 407 days) after starting REVTORPYK. Monitor patients receiving REVTORPYK for rash and infectious sequelae. Instruct patients to limit sun exposure during REVTORPYK treatment.

Withhold, reduce dose, or permanently discontinue REVTORPYK based on severity [see Dosage and Administration (2.4) ] .

5.3Hyperglycemia Severe hyperglycemia can occur in patients treated with REVTORPYK. Hyperglycemia is associated with drugs that inhibit the PI3K/AKT/mTOR pathway. In Study 1 of VIKTORIA-1, increased fasting glucose (FG) from baseline occurred in 46% of patients treated with REVTORPYK in combination with fulvestrant and palbociclib, including Grade 1 (FG >ULN to 160 mg/dL) in 36% of patients, Grade 2 (FG >160 to 250 mg/dL) in 8% of patients and Grade 3 (FG >250 to 500 mg/dL) in 0.9% of patients.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Stomatitis [see Warnings and Precautions (5.1) ] Dermatologic adverse reactions [see Warnings and Precautions (5.2) ] Hyperglycemia [see Warnings and Precautions (5.3) ] The most common (≥20%) adverse reactions, including laboratory abnormalities when given in combination with fulvestrant and palbociclib were decreased white blood cells, decreased neutrophils, decreased hemoglobin, decreased lymphocytes, stomatitis, nausea, decreased platelets, increased fasting glucose, fatigue, vomiting, rash, constipation, diarrhea, increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), musculoskeletal pain, decreased sodium, and increased eosinophils.

( 6.1 ) The most common (≥20%) adverse reactions, including laboratory abnormalities when given in combination with fulvestrant were stomatitis, increased fasting glucose, increased eosinophils, decreased hemoglobin, nausea, rash, increased ALT, fatigue, musculoskeletal pain, decreased lymphocytes, vomiting, increased AST, pruritus, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Celcuity Inc. at 1-877-4-CELCUITY (1-877-423-5284) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of REVTORPYK was evaluated in 383 adult patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer without a detectable PIK3CA mutation in Study 1 of VIKTORIA-1 [see Clinical Studies (14) ] .

Patients received either Arm A: REVTORPYK 180 mg intravenously once weekly for 3 weeks on followed by 1 week off (Days 1, 8, 15 for each 28-day cycle) in combination with fulvestrant 500 mg intramuscularly on cycle 1 Days 1 and 15, and then at Day 1 of each subsequent 28-day cycle and palbociclib 125 mg orally once daily for 21 days followed by 7 days off treatment for each 28-day cycle (n = 130); or Arm B: REVTORPYK in combination with fulvestrant (n = 130); or Arm C: fulvestrant alone (n = 123). The dose, route of administration, and frequency of each drug in Arms B and C were the same as Arm A.

The median duration of exposure for REVTORPYK plus fulvestrant and palbociclib was 6.2 months (range: 0.5 to 25 months) and 5.7 months (range: 0 to 26 months) for REVTORPYK plus fulvestrant.

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. ( 8.2 )

8.1Pregnancy Risk Summary REVTORPYK is used in combination with fulvestrant, with or without palbociclib. Refer to the Prescribing Information for fulvestrant and palbociclib for pregnancy information. When used in combination with REVTORPYK, advise patients to use effective contraception during treatment and for the longest post-treatment duration recommended in the Prescribing Information of any of the individual products.

Based on its mechanism of action, REVTORPYK can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data in pregnant women to inform the drug-associated risk. Animal reproductive toxicity studies have not been conducted with REVTORPYK.

Inhibition of PI3K and mTOR pathways have been associated with adverse embryo-fetal growth and lethality in animals ( see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data PIK3CA knockout mice experienced developmental delay at embryonic day 9.5 and mortality between embryonic day 9.5 and 10.5. mTOR knockout mice experienced early lethality by embryonic day 7.5.

In both animal models, early embryonic death was a result of impaired cell proliferation and structural development.

8.2Lactation Risk Summary REVTORPYK is used in combination with fulvestrant, with or without palbociclib. Refer to the Prescribing Information for fulvestrant and palbociclib for lactation information. When used in combination with REVTORPYK, advise patients to not breastfeed during treatment and for the longest post-treatment duration recommended in the Prescribing Information of any of the individual products.

There are no data on the presence of gedatolisib or its metabolites in human milk, its effects on milk production, or a breastfed child. Because of the potential for serious adverse reactions in a breastfed child, advise lactating women to not breastfeed during treatment with REVTORPYK and for 2 weeks after the last dose.

8.3Females and Males of Reproductive Potential REVTORPYK is used in combination with fulvestrant, with or without palbociclib. Refer to the Prescribing Information for fulvestrant and palbociclib for contraception and infertility information. When used in combination with REVTORPYK, advise patients to use effective contraception during treatment and for the longest post-treatment duration recommended in the Prescribing Information of any of the individual products.

Based on its mechanism of action, REVTORPYK can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating treatment with REVTORPYK. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with REVTORPYK and for 2 weeks after the last dose.

Males Advise male patients with female partners of reproductive potential to use effective contraception during treatment with REVTORPYK and for 2 weeks after the last dose. Infertility Based on animal studies, REVTORPYK may impair fertility in females and males of reproductive potential. Findings in animals were reversible [see Nonclinical Toxicology (13.1) ] .

8.4Pediatric Use The safety and efficacy of REVTORPYK in pediatric patients have not been established.

8.5Geriatric Use Of 260 patients who received REVTORPYK, 55 patients (21%) were ≥65 and <75 years of age and 17 patients (6.5%) were ≥75 years of age [see Clinical Studies (14) ] . In patients treated with REVTORPYK in combination with fulvestrant and palbociclib, the incidence of Grade ≥3 stomatitis and rash was higher in patients ≥65 years of age (37% and 11%, respectively) compared to younger patients (16% and 4.3%, respectively).…

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Gedatolisib is a kinase inhibitor of class I PI3K isoforms (α, β, δ, γ) and mTOR complexes mTORC1 and mTORC2, resulting in downstream inhibition of multiple effectors, including AKT. In estrogen receptor (ER)-positive breast cancer cell lines and xenograft models harboring wild-type or mutant PIK3CA , gedatolisib induced apoptosis and anti-proliferative effects in vitro and reduced tumor cell growth in vivo . In a human ER-positive breast cancer xenograft model harboring a PIK3CA mutation, the combination of gedatolisib with palbociclib and fulvestrant increased tumor growth inhibition compared to each treatment alone or the doublet combinations.

12.2Pharmacodynamics Exposure-Response Relationships The exposure-response relationship and time course of pharmacodynamic response for the effectiveness of gedatolisib have not been fully characterized. An increased incidence of stomatitis or mucositis (Grade 3 and 4), nausea, vomiting, hyperglycemia, and adverse reaction leading to dosage modification or discontinuation was observed with higher gedatolisib exposure at the dose range of 10 mg to 319 mg (0.06 to 1.8 times the approved recommended dose). Cardiac Electrophysiology At weekly doses up to 319 mg (1.8 times the recommended dose), clinically significant QTc interval prolongation was not observed.

12.3Pharmacokinetics Gedatolisib pharmacokinetic parameters were observed at the approved recommended dosage in patients with breast cancer and are presented as mean (% coefficient of variation [%CV]), unless otherwise specified. Gedatolisib maximum plasma concentration (C max ) is 13,700 (29%) ng/mL and area under the curve (AUC) is 21,400 (21%) ng·h/mL. Gedatolisib C max and AUC values increase dose proportionally in the dose range 10 mg to 319 mg (0.06 to 1.8 times the recommended dose).

No accumulation of gedatolisib is observed after once-weekly administration. Distribution Gedatolisib plasma protein binding is 98%, and is not concentration dependent, in vitro. Gedatolisib blood-to-plasma ratio is 0.87, in vitro.

Gedatolisib volume of distribution is 393 L. Elimination Gedatolisib elimination half-life (t 1/2 ) is 36 hours with an estimated clearance of 8 (23%) L/hour. Excretion After a single dose of radiolabeled gedatolisib 89 mg to healthy subjects, approximately 67.4% of the dose was recovered in feces (67% unchanged) and 12.2% in urine (11.6% unchanged).

Specific Populations No clinically significant effects on the pharmacokinetics of gedatolisib were observed based on age (21 to 84 years), sex, race (White [78%], Asian [9.1%], Black or African American [4.1%]) body weight (35 to 168 kg), mild hepatic impairment (total bilirubin ≤1.5 × ULN and any AST) or estimated glomerular filtration rate (eGFR) ≥ 45 mL/min/1.73 m 2 (MDRD equation). The effect of moderate (total bilirubin >1.5 to 3 times ULN with any AST) or severe (total bilirubin >3 x ULN with any AST) hepatic impairment, eGFR <45 mL/min/1.73 m 2 , or dialysis on gedatolisib pharmacokinetics is unknown.

Drug Interactions Clinical Studies and Model-Informed Approaches No clinically significant differences in the pharmacokinetics of the following drugs were observed when used concomitantly with gedatolisib: metformin (MATE1, MATE2-K, and OCT1 substrate), rosuvastatin (BCRP substrate), or repaglinide (CYP2C8 sensitive substrate). In Vitro Studies CYP450 Enzymes: Gedatolisib is not an inhibitor of CYP1A2, CYP2A6, or CYP2B6. The ability of gedatolisib to induce CYP450 enzymes is unknown given the results of the vitro studies were inconclusive due to decreased viability of hepatocytes.

Transporter Systems: Gedatolisib is a substrate of P-gp and BCRP and is not a substrate for OATP1B1, OATP1B3, OCT1, NTCP, MRP2, or MRP3. Gedatolisib did not inhibit P-gp, OATP1B1, OATP1B3, OAT1, OAT3, OCT2, and BSEP.
