Definitions
- This invention relates generally to immediate release fenofibrate dosage forms.
- Fenofibrate is an active principle which is very poorly soluble in water, and the absorption of fenofibrate in the digestive tract is limited. An increase in its solubility leads to better digestive absorption.
- Various approaches have been explored in order to increase the solubility of fenofibrate, including micronization of the active principle, addition of a surfactant, and comicronization of fenofibrate with a surfactant.
- Fenofibrate is freely soluble in methanol and acetonitrile, and insoluble in water. Having no ionizable group, fenofibrate solubility is not influenced by changes in medium pH. However, the aqueous solubility of Fenofibrate can be improved in the presence of surfactants. As the concentration of the surfactant sodium lauryl sulfate, for example, increases from 0.0 M to 0.1 M, fenofibrate solubility increases from 0.8 mg/L to 910.8 mg/L.
- U.S. Patent Number 4,800,079 (January 24, 1989, Jean-Francois Boyer) describes a granular medicine based on fenofibrate, each granule comprising an inert core, a layer based on fenofibrate, and a protective layer.
- the medicine is characterized in that the fenofibrate is present in the form of crystalline microparticles having a size of less than 30 microns, and preferably less than 10 microns.
- the layer based on fenofibrate includes a binder selected from the group consisting of methacrylic polymers, polyvinylpyrolidone, cellulose derivatives, and polyethylene glycols.
- U.S. Patent Number 7,101,574 (September 5, 2006, Bruno Criere et.al.) describes a pharmaceutical composition containing micronized fenofibrate, a surfactant and a cellulose derivative as a binder, preferably hydroxypropylmethylcellulose.
- the cellulose derivative represents less than 20 wt. % of the composition, while the fenofibrate is present in an amount greater than or equal to 60% by weight of the pharmaceutical composition.
- the disclosed formulation provides enhanced bioavailability of the active principle.
- EP Patent 0256933 describes fenofibrate granules containing micronized fenofibrate to increase fenofibrate bioavailability.
- the fenofibrate microparticles are less than 50 micron in size, and polyvinylpyrrolidone is used as a binder.
- the document describes other types of binder, such as methacrylic polymers, cellulose derivatives and polyethylene glycols.
- EP Patent 0330532 describes improving the bioavailability of fenofibrate by comicronizing it with a surfactant, such as sodium lauryl sulfate.
- the comicronized product is then granulated by wet granulation in order to improve the flow capacities of the powder and to facilitate the transformation into gelatin capsules.
- This comicronization allows a significant increase in the bioavailability compared to the use of fenofibrate described in EP 0256933.
- the granules described in EP 0330532 contain polyvinylpyrrolidone as a binder.
- EP 0330532 teaches that the comicronization of fenofibrate with a solid surfactant improves the bioavailability of fenofibrate compared to either micronized fenofibrate, or to the combination of a surfactant and of micronized fenofibrate.
- the formulation of EP 0330532 is unsatisfactory, as it does not provide complete bioavailability of the active ingredient.
- the technique of co- micronizing fenofibrate with a solid surfactant improves dissolution of fenofibrate, but still produces incomplete dissolution.
- Various embodiments disclosed herein relate to a dosage form comprising an effective amount of fenofibric acid, pharmaceutically acceptable salts thereof, pharmaceutically acceptable esters thereof, or prodrugs thereof.
- the active agent is fenofibrate, an ester of fenofibric acid which is hydrolyzed to fenofibric acid in vivo.
- Fenofibrate is a prodrug of fenofibric acid.
- a fenofibrate formulation comprises a population of low bioavailability fenofibrate-containing beads (slow beads), and a population of high bioavailability fenofibrate-containing beads (fast beads).
- a portion of the desired fenofibrate dose is included in the slow beads, and the remainder of the desired fenofibrate dose is included in the fast beads.
- the fast and slow beads are combined to produce a single dosage form having a desired bioavailability, as measured by the rate and extent of absorption. Specifically, the rate and extent of absorption is measured by the parameters AUCL, AUCI, and Cpeak.
- the parameter AUCL is the area under the plasma concentration-time curve from time zero to time t, where t is the last time point with measurable concentration for individual formulation.
- the parameter AUCI is the area under the plasma concentration-time curve from time zero to time infinity. Additionally, Cpeak is the maximum plasma concentration of the drug.
- the overall bioavailability of the dosage form may be modulated by the presence of low bioavailability fenofibrate-containing beads.
- the dosage form comprises a plurality of first granules and a plurality of second granules combined in a weight ratio of said first granules to said second granules of between about 50:50 and about 90: 10, where the dosage form provides a peak plasma concentration of fenofibric acid of between 4000 ng/mL and 4800 ng/mL fenofibrate when administered to a human subject.

- Hypromellose (Pharmacoat® 603) was used as a binder in the drug suspension, as it aids in adhering the drug to the sugar sphere substrate during processing.
- SLS Sodium lauryl sulfate
- Sodium lauryl sulfate is a commonly used excipient in solid oral dosage forms to enhance wetting and improve drug dissolution rate. This excipient is employed to enhance the aqueous wettability of fenofibrate in the drug layering suspension and to enhance the drug release from the high bioavailability, or fast, drug layered beads.
- Sodium lauryl sulfate was not used in the slow beads in the following examples, resulting in reduced drug release from the slow beads.
- formulations disclosed herein were administered to healthy adult volunteers in bioequivalence studies under fasting and fed conditions. The bioavailability achieved with the formulations disclosed herein is comparable to the bioavailability achieved with the administration of Lupin's ANTARA® capsules, where the ANTARA® capsules contain a single population of granules having a defined concentration of fenofibrate.
- the formulations disclosed herein include two populations of fenofibrate beads, including fast beads which have a higher bioavailability than the beads in ANTARA® capsules, and slow beads which have a lower bioavailability than the beads in ANTARA® capsules.
- Manufacture of Fenofibrate Capsules proceeds via encapsulation of Fenofibrate Intermediate Beads blend using two separate capsule filling stations.
- Filling station I is used to encapsulate the Fast Fenofibrate Intermediate Beads and the Filling station II is used to encapsulate the Slow Fenofibrate Intermediate Beads.
- the manufacturing process was shown to provide a finished product with acceptable assay and content uniformity characteristics.
- the drug layer suspension in this invention is manufactured using a high speed homogenizer mixer (Ross Model HSM 105, attached with a rotor/stator mixing blade used for the large scale manufacturing).
- a high speed homogenizer mixer Ross Model HSM 105
- several different types of mixer/disperser mixing head attachments were evaluated: slotted rotor/stator disperser, saw tooth disperser, slotted stator, and a fine screen stator with slotted disperser.
- Table 1 summarizes the formulation compositions and the drug release characteristics from these experiments. All formulations processed well and their drug release characteristics were similar, indicating that mixer type has no impact on formulation performance. Based on this evaluation, the rotor/stator configuration was chosen for the manufacture of the drug layering suspension.
- the process requires the suspension to be mixed with a homogenizer mixer for a minimum of 8 hours prior to drug layering, with continuous agitation of the suspension maintained throughout the drug layering process.
- the fluidization pattern in the rotor processor can be best characterized as a spiraling helix. Three factors act on the beads or pellets or particles (materials) to produce this flow pattern.
- the rotating disk of the ROTOR insert provides centrifugal force which forces the rotating materials toward the wall of the processing chamber at the periphery of the rotor insert, while conditioned upward airflow through the rotor gap develops a vertical force causing the materials to become fluidized.
- the fluidization air pushes the moving materials upward into the expansion chamber until gravity overcomes the upward air velocity and the material falls toward the center of the disk where there is little air movement.
- the drug layer suspension is sprayed tangentially onto the rotating particles, while heated process air causes the applied drug layer suspension to dry before the particles move again into the spraying zone. This cyclical process is repeated many hundreds of times until the appropriate quantity of solids are applied to the rotating core substrate (material).
- the efficiency of the drug layering process is dependent on the relationship between particle movement within the processor, drug layering suspension spray rate and the rate of solvent evaporation.
- the movement of the particles during rotor drug layering process is dependent on rotor speed and air flow. Rotor speed is considered a critical parameter since it can affect the integrity of the beads. Slow speeds can lead to product agglomeration while excessive speeds can cause attrition. Rotor speed is adjusted to maintain proper particle movement as the weight of the batch increases during drug layering process. Once proper movement of the particle bed is established, the deposition of drug layering solids onto the core substrate is controlled by the rate at which drug layering suspension is applied to core beads or pellets, and the rate at which solvent is removed from the system.
- Two formulations of fenofibrate containing beads were prepared. Each formulation was prepared by spraying a fenofibrate suspension onto sugar spheres having a size of 35 to 45 mesh in a fluidized bed. In one formulation (designated X07-047- 58A1), the drug suspension included fenofibrate and HPMC in a ratio of 4:1, while in the other formulation (designated X07-047-62A1), the drug suspension included fenofibrate and HPMC in a ratio of 2.4: lwere evaluated. The amounts of the various ingredients are set forth in Table 3 below. The bead formulations are prepared in a fluidized bed by spraying a water-based suspension of micronized fenofibrate, HPMC, and sodium lauryl sulfate onto the sugar spheres.
- Dissolution condition 1000 mL purified water, 0.01 M sodium lauryl sulfate,
- a formulation containing fenofibrate and HPMC in a ratio of 4: 1 was evaluated.
- the formulation additionally contained 2%, by weight of the formulation, of the anionic surfactant SLS, as seen in Table 7.
- FL-M-60 large scale fluid bed dryer
- Simethicone was incorporated to the drug layering suspension at a low level (0.044 %w/w) to minimize foaming during preparation.
- the dried beads were blended with micronized talc, screened to remove agglomerates, and machine encapsulated into the two piece hard gelatin capsules
- Table 7 (2% SLS, 4: 1 Drug:HPMC) is comparable to the drug release rate of the branded product ANTARA®. Both formulations release 54% of the incorporated fenofibrate in 10 minutes; 92% to 93% of the incorporated fenofibrate in 30 minutes; and substantially all of the incorporated fenofibrate in 60 minutes. [0071] The formulation of Table 7 was assessed in a pilot bioequivalence study, and compared to ANTARA® Capsules. Both the formulation of Table 7 and the ANTARA® Capsules contained 130 mg fenofibrate. The pilot bioequivalence study was an open- label, single-dose, randomized, two-period, two-treatment crossover study, using 24 normal healthy subjects. A summary of the pharmacokinetic data is presented in Table 9.
- bioequivalence between a branded product and a generic equivalent.
- bioequivalence depends on several natural log transformed parameters associated with the rate and extent of absorption. Specifically, the entire 90% confidence interval for the ratio of the test to reference area under the curve from zero to the last detectable concentration, AUCL, must fall between 80 and 125% of the corresponding AUCL of the branded product for therapeutic equivalence. Additionally, the entire 90% confidence interval for the ratio of the test to reference maximum plasma concentration, Cpeak, must also fall between 80 and 125% of the corresponding Cpeak of the branded product for therapeutic equivalence to be declared.
- the Cpeak parameter for the formulation of Table 7 is 138% of the corresponding value for the branded product, with a 90% confidence interval of 128.1 %- 155%. This result falls outside the FDA's desired confidence interval ratio of 80%- 125%. Accordingly, the formulation of Table 7 exhibits higher bioavailability under fasting conditions than the reference product ANTARA®. In this in vivo evaluation, the formulation of Table 7 used smaller size beads (35-45 mesh) than ANTARA® capsules, which might have caused increased bioavailability due to larger surface area of the dosage forms.
- Table 10 is faster than the drug release rate of the branded product ANTARA®.
- Formulation #1000374 containing 2% sodium lauryl sulfate, releases 64% of the incorporated fenofibrate in 10 minutes; and substantially all of the incorporated fenofibrate in 30 minutes.
- ANTARA® in contrast, releases 54% of the incorporated fenofibrate in 10 minutes; and 93% of the incorporated fenofibrate in 30 minutes.
- Formulation #1000375 containing 0.5% sodium lauryl sulfate, is more closely comparable to ANTARA® capsules, releasing 61% of the incorporated fenofibrate in 10 minutes; 94% of the incorporated fenofibrate in 30 minutes; and substantially all of the incorporated fenofibrate in 60 minutes.
- Formulation X07-047-82A1 containing 6.5% w/w Pharmacoat 603 with no sodium lauryl sulfate was manufactured in a large scale equipment as lot 1000442 using Size#0EL capsules shell and evaluated in a bioequivalence study versus ANTARA® capsules. Table 16 describes this formulation.
- the capsules of Table 16 release the drug more slowly than the comparative ANTARA® capsules. After 10 minutes, the comparative ANTARA® capsules released 54% of the drug, while the capsules of Table 14 released onlyl4% of the drug. Additionally, the capsules of Table 14 were assessed in a bioequivalence study versus ANTARA® Capsules, 130 mg in an open-label, single-dose, randomized, two-period, two-treatment crossover study using 32 normal healthy subjects (27 completed the study). The methodology was similar to the methodology used in Example 3. A summary of the pharmacokinetic data from this study is presented in Table
- the capsules of Table 16 exhibited poor bioavailability under fasting conditions due to a low AUCL and Cpeak.
- the results of Table 18 indicate that the capsules of Table 16, containing fenofibrate and HPMC in a ratio of 8: 1 and no sodium lauryl sulfate, exhibited low absorption (AUCL) compared to ANTARA® capsules.
- the capsules of Table 16 showed between 53% and 59%% of the absorption (AUCL) observed with the branded product, with a confidence interval of 90%.
- the Cpeak parameter for capsules of Table 16 has a 90% confidence interval of 45% to 53% when compared to the branded product. This result falls outside the FDA's desired confidence interval ratio of 80%- 125%, and indicates that the capsules of Table 16 are not bioequivalent to ANTARA® capsules.
- Type B beads 20 is also substantially slower than a capsule prepared using Type B beads alone, where the Type B beads contain fenofibrate and HPMC in a ratio of 4.1: 1, with 2% sodium lauryl sulfate.
- Treatment B Lot 1000530 contains 75% Fast Beads (2%SLS) and 25% Slow Beads (No SLS); Dose: lx
- Treatment C Antara Capsules, Lot : B08017 ; Dose: 1 x 130 mg ; Oscient/Lupin
- a large scale batch, Formulation#1000596 was manufactured using the Formulation composition of 1000530 (shown in Table 20).
- This capsule contains two different types of Fenofibrate Intermediate Beads, one containing no surfactant (Fenofibrate Intermediate Beads, Type C, 520 mg/g) and the other containing sodium lauryl sulfate as a surfactant (Fenofibrate Intermediate Beads, Type B).
- Each capsule contains 25%w/w Fenofibrate Intermediate Beads Type C (520 mg/g) and 75%w/w Fenofibrate Intermediate Beads Type B which corresponds to theoretical fill weights of 62.5 mg and 187.725 mg, respectively.
- the actual fill weight of each bead is adjusted based on the potency factor assigned to each bead prior to encapsulation.
- Each bead type was filled into the capsule shell using a separate dosing station during encapsulation.
- 100596, 130 mg are bioequivalent to ANTARA® Capsules, 130 mg, following a single, oral 130 mg (1 x 130mg capsule) dose administered under fasting and post-prandial conditions.
- a summary of the pharmacokinetic data from this study is presented in Table 23 and Table 24.
- Figure 5 and Figure 6 display the pharmacokinetic profile, specifically plasma concentration of fenofibrate over time, for Capsules of Lot. 100596, 130 mg which are bioequivalent to ANTARA® Capsules, 130 mg.
