⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
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.
🛈 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.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Use in patients with advanced liver disease: ORKAMBI should be used with caution in these patients and only if the benefits are expected to outweigh the risks. If ORKAMBI is used in these patients, they should be closely monitored after the initiation of treatment and the dosage should be reduced. Liver function decompensation, including liver failure leading to death, has been reported in CF patients with pre-existing cirrhosis with portal hypertension.
( 2.2 , 5.1 , 6.1 ) Liver-related events: Elevated transaminases (ALT/AST) have been observed in some cases associated with elevated bilirubin. Measure serum transaminases and bilirubin before initiating ORKAMBI, every 3 months during the first year of treatment, and annually thereafter. For patients with a history of ALT, AST, or bilirubin elevations, more frequent monitoring should be considered.
Interrupt dosing in patients with ALT or AST >5 × upper limit of normal (ULN), or ALT or AST >3 × ULN with bilirubin >2 × ULN. Following resolution, consider the benefits and risks of resuming dosing. ( 5.2 , 6.1 ) Hypersensitivity reactions: Angioedema and anaphylaxis have been reported with ORKAMBI in the postmarketing setting.
Initiate appropriate therapy in the event of a hypersensitivity reaction. ( 5.3 ) Intracranial hypertension: Intracranial hypertension (IH) has been reported in the postmarketing setting with the use of ORKAMBI. If an unusual headache or visual disturbances occur during treatment, and IH is suspected, interrupt ORKAMBI and refer for prompt medical evaluation.
( 5.4 ) Neuropsychiatric events, including suicidal thoughts and behaviors : Serious neuropsychiatric events, including symptoms of anxiety, depression, suicidal ideation and behavior, and sleep disturbances, have been reported in the postmarketing setting for ORKAMBI or drugs containing the same or similar active ingredients. Monitor patients closely for new or worsening symptoms. Consider the risks and benefits for the individual patient to determine if therapy with ORKAMBI should be interrupted at the occurrence of neuropsychiatric symptoms.
( 5.5 ) Respiratory events: Chest discomfort, dyspnea, and respiration abnormal were observed more commonly during initiation of ORKAMBI. Clinical experience in patients with percent predicted FEV 1 (ppFEV 1 ) <40 is limited, and additional monitoring of these patients is recommended during initiation of therapy. ( 5.6 , 6.1 ) Blood pressure: Increased blood pressure has been observed in some patients.
Periodically monitor blood pressure in all patients. ( 5.7 , 6.1 ) Drug interactions: Use with sensitive CYP3A substrates or CYP3A substrates with a narrow therapeutic index may decrease systemic exposure of the medicinal products and co-administration is not recommended. Hormonal contraceptives should not be relied upon as an effective method of contraception and their use is associated with increased menstruation-related adverse reactions.
Use with strong CYP3A inducers may diminish exposure of ivacaftor, which may diminish its effectiveness; therefore, co-administration is not recommended. ( 5.8 , 6.1 , 7 , 12.3 ) Cataracts: Non-congenital lens opacities/cataracts have been reported in pediatric patients treated with ORKAMBI and ivacaftor, a component of ORKAMBI. Baseline and follow-up examinations are recommended in pediatric patients initiating ORKAMBI.

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 overall safety profile of ORKAMBI is based on the pooled data from 1108 patients with CF aged 12 years and older who are homozygous for the F508del mutation in the CFTR gene and who received at least one dose of study drug in two double-blind, placebo-controlled, Phase 3 clinical trials, each with 24 weeks of treatment (Trials 1 and 2).
In addition, the following clinical trials have been conducted: A 24-week, open-label trial (Trial 3) in 58 patients with CF aged 6 through 11 years homozygous for the F508del-CFTR mutation. A 24-week, placebo-controlled trial (Trial 4) in 204 patients aged 6 through 11 years homozygous for the F508del-CFTR mutation. A 24-week, open-label trial (Trial 5) in 46 patients aged 12 years and older homozygous for the F508del-CFTR mutation and with advanced lung disease (ppFEV 1 <40).
A 24-week, open-label trial (Trial 6) in 60 patients aged 2 through 5 years homozygous for the F508del-CFTR mutation. A 24-week, open-label trial (Trial 7) in 46 patients aged 1 through 2 years homozygous for the F508del - CFTR mutation. Of the 1108 patients, in the pooled analyses of Trial 1 and Trial 2, 49% were female and 99% were Caucasian; 369 patients received ORKAMBI every 12 hours and 370 patients received placebo.
The proportion of patients who prematurely discontinued study drug due to adverse events was 5% for patients treated with ORKAMBI and 2% for patients who received placebo. Serious adverse reactions, whether considered drug-related or not by the investigators, that occurred more frequently in patients treated with ORKAMBI included pneumonia, hemoptysis, cough, increased blood creatine phosphokinase, and transaminase elevations. These occurred in 1% or less of patients.
Table 3 shows adverse reactions occurring in ≥5% of patients with CF aged 12 years and older treated with ORKAMBI who are homozygous for the F508del mutation in the CFTR gene that also occurred at a higher rate than in patients who received placebo in the two double-blind, placebo-controlled trials.

🔄 Drug Interactions ▾
5.8Drug Interactions Substrates of CYP3A Lumacaftor is a strong inducer of CYP3A. Administration of ORKAMBI may decrease systemic exposure of medicinal products that are substrates of CYP3A, which may decrease therapeutic effect. Co-administration with sensitive CYP3A substrates or CYP3A substrates with a narrow therapeutic index is not recommended.
ORKAMBI may substantially decrease hormonal contraceptive exposure, reducing their effectiveness and increasing the incidence of menstruation-associated adverse reactions, e.g., amenorrhea, dysmenorrhea, menorrhagia, menstrual irregular (27% in women using hormonal contraceptives compared with 3% in women not using hormonal contraceptives). Hormonal contraceptives, including oral, injectable, transdermal, and implantable, should not be relied upon as an effective method of contraception when co-administered with ORKAMBI [see Adverse Reactions (6.1) , Drug Interactions (7.3 , 7.11) , and Clinical Pharmacology (12.3) ] .
Strong CYP3A Inducers Ivacaftor is a substrate of CYP3A4 and CYP3A5 isoenzymes. Use of ORKAMBI with strong CYP3A inducers, such as rifampin, significantly reduces ivacaftor exposure, which may reduce the therapeutic effectiveness of ORKAMBI. Therefore, co-administration with strong CYP3A inducers (e.g., rifampin, St.
John's wort [ Hypericum perforatum ]) is not recommended [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] .
7 DRUG INTERACTIONS See Full Prescribing Information for a complete list. ( 2.3 , 7 , 12.3 ) Potential for Other Drugs to Affect Lumacaftor/Ivacaftor
7.1Inhibitors of CYP3A Co-administration of lumacaftor/ivacaftor with itraconazole, a strong CYP3A inhibitor, did not impact the exposure of lumacaftor, but increased ivacaftor exposure by 4.3-fold. Due to the induction effect of lumacaftor on CYP3A, at steady-state, the net exposure of ivacaftor is not expected to exceed that when given in the absence of lumacaftor at a dose of 150 mg every 12 hours (the approved dose of ivacaftor monotherapy). Therefore, no dosage adjustment is necessary when CYP3A inhibitors are initiated in patients currently taking ORKAMBI.
However, when initiating ORKAMBI in patients taking strong CYP3A inhibitors, reduce the ORKAMBI dosage as recommended for the first week of treatment to allow for the steady-state induction effect of lumacaftor. Following this period, continue with the recommended daily dose [see Dosage and Administration (2.3) ] . Examples of strong CYP3A inhibitors include: ketoconazole, itraconazole, posaconazole, and voriconazole. telithromycin, clarithromycin.
No dosage adjustment is recommended when used with moderate or weak CYP3A inhibitors.
7.2Inducers of CYP3A Co-administration of lumacaftor/ivacaftor with rifampin, a strong CYP3A inducer, had minimal effect on the exposure of lumacaftor, but decreased ivacaftor exposure (AUC) by 57%. This may reduce the effectiveness of ORKAMBI. Therefore, co-administration with strong CYP3A inducers, such as rifampin, rifabutin, phenobarbital, carbamazepine, phenytoin, and St.
John's wort ( Hypericum perforatum ), is not recommended [see Warnings and Precautions (5.8) and Clinical Pharmacology (12.3) ] . No dosage adjustment is recommended when used with moderate or weak CYP3A inducers. Potential for Lumacaftor/Ivacaftor to Affect Other Drugs
7.3CYP3A Substrates Lumacaftor is a strong inducer of CYP3A. Co-administration of lumacaftor with ivacaftor, a sensitive CYP3A substrate, decreased ivacaftor exposure by approximately 80%. Administration of ORKAMBI may decrease systemic exposure of medicinal products which are substrates of CYP3A, thereby decreasing the therapeutic effect of the medicinal product.
Co-administration of ORKAMBI is not recommended with sensitive CYP3A substrates or CYP3A substrates with a narrow therapeutic index [see Warnings and Precautions (5.8) and Clinical Pharmacology (12.3) ] such as: Benzodiazepines : midazolam, triazolam (consider an alternative to these benzodiazepin…

8.1Pregnancy Risk Summary There are limited and incomplete human data from clinical trials and postmarketing reports on use of ORKAMBI or its individual components, lumacaftor or ivacaftor, in pregnant women to inform a drug-associated risk. In animal reproduction studies, oral administration of lumacaftor to pregnant rats and rabbits during organogenesis demonstrated no adverse effects on fetal development at doses that produced maternal exposures up to approximately 8 (rats) and 5 (rabbits) times the exposure at the maximum recommended human dose (MRHD).
Oral administration of ivacaftor to pregnant rats and rabbits during organogenesis demonstrated no adverse effects on fetal development at doses that produced maternal exposures up to approximately 7 (rats) and 45 (rabbits) times the exposure at the MRHD. No adverse developmental effects were observed after oral administration of either lumacaftor or ivacaftor to pregnant rats from organogenesis through lactation at doses that produced maternal exposures approximately 8 and 5 times the exposures at the MRHD, respectively (see Data ) .
There are no animal reproduction studies with concomitant administration of lumacaftor and ivacaftor. The background risk of major birth defects and miscarriage for the indicated population is unknown. 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 Lumacaftor In an embryo-fetal development (EFD) study, pregnant rats were administered lumacaftor at oral doses of 500, 1000, or 2000 mg/kg/day during the period of organogenesis from gestation days 7-17. Lumacaftor did not affect fetal development or survival at exposures up to 8 times the MRHD (on an AUC basis at maternal oral doses up to 2000 mg/kg/day). In an EFD study, pregnant rabbits were administered lumacaftor at oral doses of 50, 100, or 200 mg/kg/day during the period of organogenesis from gestation days 7-19.
Lumacaftor did not affect fetal development or survival at exposures up to 5 times the MRHD (on an AUC basis at maternal oral doses up to 200 mg/kg/day). Maternal toxicity as evidenced by decreased body weight, decreased food consumption, and clinical signs was observed at 100 and 200 mg/kg/day without any adverse fetal effects. In a pre- and post-natal development study in pregnant female rats administered lumacaftor at 250, 500, or 1000 mg/kg/day from gestation day 6 through lactation day 20, lumacaftor had no effects on delivery or growth and development of offspring at exposures up to 8 times the MRHD (on an AUC basis at maternal oral doses up to 1000 mg/kg/day).
Placental transfer of lumacaftor was observed in pregnant rats and rabbits. Ivacaftor In an EFD study, pregnant rats were administered ivacaftor at oral doses of 50, 100, or 200 mg/kg/day during the period of organogenesis from gestation days 7-17. Ivacaftor did not affect fetal survival at exposures up to 7 times the MRHD (based on summed AUCs for ivacaftor and its metabolites at maternal oral doses up to 200 mg/kg/day).
Maternal toxicity (i.e., decreased mean body weight and body weight gain) was observed at 100 and 200 mg/kg/day (5 and 7 times the exposure at the MRHD, respectively) and was associated with a decrease in fetal body weights at a maternal dose of 200 mg/kg/day (7 times the MRHD). In an EFD study, pregnant rabbits were administered ivacaftor at oral doses of 25, 50, or 100 mg/kg/day during the period of organogenesis from gestation days 7-19. Ivacaftor did not affect fetal development or survival at exposures up to 45 times the MRHD (on an ivacaftor AUC basis at maternal oral doses up to 100 mg/kg/day).
Maternal toxicity (i.e., death, decreased food consumption, decreased mean body weight and body weight gain, decreased clinical condition, abortions) was observed at doses greater than or equal to 50 mg/kg/day (approximately 15…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of ORKAMBI in pediatric patients aged one year and older have been established. Use of ORKAMBI in these age groups is supported by evidence from adequate and well-controlled studies of ORKAMBI in patients aged 12 years and older [see Clinical Studies (14) and Adverse Reactions (6.1) ] with additional data as follows: Extrapolation of efficacy in patients aged 12 years and older homozygous for the F508del mutation in the CFTR gene to pediatric patients aged 1 through 11 years with support from population pharmacokinetic analyses showing similar drug exposure levels in patients aged 12 years and older and in patients aged 1 through 11 years [see Clinical Pharmacology (12.3) ] .
Safety data were obtained from a 24-week, open-label, clinical trial in 58 patients aged 6 through 11 years, mean age 9 years (Trial 3) and a 24-week, placebo-controlled, clinical trial in 204 patients aged 6 through 11 years (Trial 4). Trial 3 evaluated subjects with a screening ppFEV 1 ≥40 [mean ppFEV 1 91.4 at baseline (range: 55 to 122.7)]. Trial 4 evaluated subjects with a screening ppFEV 1 ≥70 [mean ppFEV 1 89.8 at baseline (range: 48.6 to 119.6)].
The safety profile of ORKAMBI in pediatric patients 6 through 11 years of age was similar to that in patients aged 12 years and older [see Adverse Reactions (6.1) ] . In Trial 3, spirometry (ppFEV 1 ) was assessed as a planned safety endpoint. The within-group LS mean absolute change from baseline in ppFEV 1 at Week 24 was 2.5 percentage points.
At the Week 26 safety follow-up visit (following a planned discontinuation) ppFEV 1 was also assessed. The within-group LS mean absolute change in ppFEV 1 from Week 24 at Week 26 was -3.2 percentage points. Additional safety data were obtained from Trial 6, a 24-week, open-label, clinical trial in 60 patients aged 2 through 5 years at screening (mean age at baseline 3.7 years).
The safety profile in Trial 6 was similar to that in patients aged 6 years and older [see Adverse Reactions (6.1) ] . Additional safety data were obtained from Trial 7, a 24-week, open-label, clinical trial in 46 patients aged 1 to 2 years at screening (mean age at baseline 18.1 months). The safety profile in Trial 7 was similar to that in patients aged 2 years and older [see Adverse Reactions (6.1) ] .
Safety was evaluated in a 96-week open-label clinical trial (Trial 8) in 52 patients (39 rolled over from Trial 7 and 13 ORKAMBI naïve) aged 1 to 2 years. Adverse reactions from trial 8 were generally similar to those reported in Trial 7. The safety and effectiveness of ORKAMBI in patients with CF younger than 1 year of age have not been established.
Cases of non-congenital lens opacities have been reported in pediatric patients treated with ORKAMBI and ivacaftor, a component of ORKAMBI. Although other risk factors were present in some cases (such as corticosteroid use and exposure to radiation), a possible risk attributable to ivacaftor cannot be excluded [see Warnings and Precautions (5.9) ] . Juvenile Animal Toxicity Data In a juvenile toxicology study in which ivacaftor was administered to rats from post-natal days 7 to 35, cataracts were observed at all dose levels, ranging from 0.3 to 2 times the MRHD (based on summed AUCs for ivacaftor and its metabolites at oral doses of 10-50 mg/kg/day).
This finding has not been observed in older animals.
🧓 Geriatric Use ▾
8.5Geriatric Use CF is largely a disease of children and young adults. Clinical trials of ORKAMBI did not include sufficient numbers of patients 65 years of age and over to determine whether they respond differently from younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE There have been no reports of overdose with ORKAMBI. The highest repeated dose was lumacaftor 1000 mg once daily/ivacaftor 450 mg q12h administered to 49 healthy subjects for 7 days in a trial evaluating the effect of ORKAMBI on electrocardiograms (ECGs). Adverse events reported at an increased incidence of ≥5% compared to the lumacaftor 600 mg/ivacaftor 250 mg dosing period and placebo included: headache (29%), transaminase increased (18%), and generalized rash (10%).
No specific antidote is available for overdose with ORKAMBI. Treatment of overdose consists of general supportive measures including monitoring of vital signs and observation of the clinical status of the patient.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The CFTR protein is a chloride channel present at the surface of epithelial cells in multiple organs. The F508del mutation results in protein misfolding, causing a defect in cellular processing and trafficking that targets the protein for degradation and therefore reduces the quantity of CFTR at the cell surface. The small amount of F508del-CFTR that reaches the cell surface is less stable and has low channel-open probability (defective gating activity) compared to wild-type CFTR protein.
Lumacaftor improves the conformational stability of F508del-CFTR, resulting in increased processing and trafficking of mature protein to the cell surface. Ivacaftor is a CFTR potentiator that facilitates increased chloride transport by potentiating the channel-open probability (or gating) of the CFTR protein at the cell surface. In vitro studies have demonstrated that both lumacaftor and ivacaftor act directly on the CFTR protein in primary human bronchial epithelial cultures and other cell lines harboring the F508del-CFTR mutation to increase the quantity, stability, and function of F508del-CFTR at the cell surface, resulting in increased chloride ion transport.
In vitro responses do not necessarily correspond to in vivo pharmacodynamic response or clinical benefit.
12.2Pharmacodynamics Sweat Chloride Evaluation Changes in sweat chloride in response to relevant doses of lumacaftor alone or in combination with ivacaftor were evaluated in a double-blind, placebo-controlled, Phase 2 clinical trial in patients with CF aged 18 years and older either homozygous or heterozygous for the F508del mutation. In that trial, 10 patients (homozygous for F508del ) completed dosing with lumacaftor alone 400 mg q12h for 28 days followed by the addition of ivacaftor 250 mg q12h for an additional 28 days and 25 patients (homozygous or heterozygous for F508del ) completed dosing with placebo.
The treatment difference between lumacaftor 400 mg q12h alone and placebo evaluated as mean change in sweat chloride from baseline to Day 28 compared to placebo was -8.2 mmol/L (95% CI: -14, -2). The treatment difference between the combination of lumacaftor 400 mg/ivacaftor 250 mg q12h and placebo evaluated as mean change in sweat chloride from baseline to Day 56 compared to placebo was -11 mmol/L (95% CI: -18, -4). Changes in sweat chloride in response to lumacaftor/ivacaftor were also evaluated in a 24-week, open-label, clinical trial (Trial 3) in 58 patients with CF, aged 6 through 11 years (homozygous for F508del ) who received lumacaftor 200 mg/ivacaftor 250 mg q12h for 24 weeks.
Patients treated with lumacaftor/ivacaftor had a reduction in sweat chloride at Day 15 that was sustained through Week 24. The within-group LS mean absolute change from baseline in sweat chloride was -20.4 mmol/L at Day 15 and -24.8 mmol/L at Week 24. In addition, sweat chloride was also assessed after a 2-week washout period to evaluate the off-drug response.
The within-group LS mean absolute change in sweat chloride from Week 24 at Week 26 following the 2-week washout period was 21.3 mmol/L. Changes in sweat chloride in response to lumacaftor/ivacaftor were also evaluated in a 24-week, open-label, clinical trial (Trial 6) in 60 patients with CF, aged 2 through 5 years (homozygous for F508del ) who received either lumacaftor 100 mg/ivacaftor 125 mg every 12 hours or lumacaftor 150 mg/ivacaftor 188 mg every 12 hours for 24 weeks. Treatment with lumacaftor/ivacaftor demonstrated a reduction in sweat chloride at Week 4 that was sustained through Week 24.
The mean absolute change from baseline in sweat chloride was –31.7 mmol/L (95% CI: -35.7, -27.6) at Week 24. In addition, sweat chloride was also assessed after a 2-week washout period to evaluate the off-drug response. The mean absolute change in sweat chloride from Week 24 at Week 26 following the 2-week washout period was an increase of 33.0 mmol/L (95% CI: 28.9, 37.1; P <0.0001).

🧬 Mechanism of Action ▾
12.1Mechanism of Action The CFTR protein is a chloride channel present at the surface of epithelial cells in multiple organs. The F508del mutation results in protein misfolding, causing a defect in cellular processing and trafficking that targets the protein for degradation and therefore reduces the quantity of CFTR at the cell surface. The small amount of F508del-CFTR that reaches the cell surface is less stable and has low channel-open probability (defective gating activity) compared to wild-type CFTR protein.
Lumacaftor improves the conformational stability of F508del-CFTR, resulting in increased processing and trafficking of mature protein to the cell surface. Ivacaftor is a CFTR potentiator that facilitates increased chloride transport by potentiating the channel-open probability (or gating) of the CFTR protein at the cell surface. In vitro studies have demonstrated that both lumacaftor and ivacaftor act directly on the CFTR protein in primary human bronchial epithelial cultures and other cell lines harboring the F508del-CFTR mutation to increase the quantity, stability, and function of F508del-CFTR at the cell surface, resulting in increased chloride ion transport.
In vitro responses do not necessarily correspond to in vivo pharmacodynamic response or clinical benefit.
