Pharmaceutical formulations suitable for treating viral infections such as HIV are disclosed, in particular tablets comprising bictegravir and lenacapavir.
Human immunodeficiency virus, type 1 (HIV-1) infection is a life-threatening and serious disease of major public health significance, with approximately 35 million people infected worldwide (Joint United Nations Programme on HIV/AIDS (UNAIDS). Global report: UNAIDS report on the global AIDS epidemic, 2013). Standard of care for the treatment of HIV-1 infection uses combination antiretroviral therapy (ART) to suppress viral replication to below detectable limits, increase CD4 cell counts, and halt disease progression.
The success of potent and well-tolerated ART means that most patients with a HIV-1 (PWH) with a history of virologic failure and viral resistance can achieve and maintain virologic suppression, although often on a complicated multi-tablet regimen dosed more than once daily, with disparate dosing schedules. A multi-tablet regimen is more difficult for PWH to adhere to consistently over the long-term, and poor adherence is a common reason for virologic failure. Low pill burden is associated with higher levels of adherence (Nachega, Clin Infect Dis 2014, 58:1297-307; Raboud, AIDS behave 2011, 15(7):1397-409). Additionally, PWH receiving single-tablet regimens are less likely to discontinue therapy (i.e. higher persistence) compared with those receiving multi-tablet regimens (Hines, Patient preference and adherence 2019, 13:1927-39). In 2 meta-analyses, PWH on a single-tablet regimen were more likely to achieve and maintain virologic suppression (Clay, Medicine, 2015, 94 (42):1-14; Clay, AIDS research and therapy 2018, 15:17). Convenience (e.g. pill burden, dosing frequency, availability of FDC or single-tablet regimen formulations) is one of the regimen-specific considerations in selecting an initial ARV regimen. Therefore, there remains a significant need to simplify treatment regimens for all PWH, including those who are virologically suppressed on a complicated regimen due to their prior history of virologic failure and viral resistance.

The inventors have found that it is possible to formulate bictegravir (in particular bictegravir sodium) and lenacapavir (in particular lenacapavir sodium) in a tablet capable of releasing each active ingredient (measured by e.g. AUCinf, Cmax) in an amount which is at least comparable to that of standard comparators (i.e. single agent tablets comprising the equivalent amount of bictegravir and lenacapavir). In particular, in some embodiments the tablets of the disclosure provide plasma concentrations (AUCinf, Cmax) of one or more of the two active pharmaceutical ingredients that is comparable to the plasma concentrations produced by the administration of a combination of single agent tablets.
Achieving comparable release of bictegravir and lenacapavir to the single agent formulations from a fixed dose combination formulation was initially a challenge because the dissolution and subsequent bioavailability of the active agents was found to vary depending on the specific dosages included in the formulations. Without being bound by any particular theory, it is believed that the two active agents interact with one another in a manner which impacts their respective solubility and resulting bioavailability. For example, the dissolution of lenacapavir from monolayer tablets comprising 75 mg bictegravir and 25 mg lenacapavir was reduced relative to the combination of the equivalent single agent tablets. Additionally, the dissolution of bictegravir from monolayer tablets comprising 75 mg bictegravir and 100 mg lenacapavir was reduced relative to the combination of the equivalent single agent tablets. There is thus a balance to be struck between the dosage of bictegravir and the dosage of lenacapavir in order to achieve sufficient dissolution of both active agents and provide bioequivalence to the combination of the single agent tablets.
As used herein, F (bioavailability) is the fraction of an administered drug that reaches the systemic circulation.
In certain specific embodiments, the tablet of the disclosure provides a bioavailability of at least about 20% of bictegravir in fasted, pentagastrin pre-treated dogs, in some embodiments, at least about 30%.

F, Cmax, AUCinf, and AUClast are standard pharmacokinetic parameters that can be estimated manually or by using modelling software well known in the art, such as the Pharsight WinNonlin package using a non-compartmental model. The general basis for calculation of these quantities is well-known (e.g. see Rowland & Tozer (2010) Clinical Pharmacokinetics and Pharmacodynamics: Concepts and Applications ISBN 978-0781750097, or Jambhekar & Breen (2012) Basic Pharmacokinetics ISBN 978-0853699804). Typically, the parameters will be assessed as the average (e.g. geometric or arithmetic mean) from within a group of at least 12 (and normally between 24 and 60) healthy human adults. Parameters should be measured in accordance with standards and practices which would be acceptable to a pharmaceutical regulatory agency such as FDA, EMA, MHLW, or WHO. The values may be based on measurements taken at appropriate intervals following the time of tablet ingestion, such as every hour, or at increasingly sparse sampling intervals, such as 1, 3, 5, 7, 9, 11, 13, 15, 20, and 24 hours after ingestion. They can be assessed either following a single-dose of drug or at steady state but will typically be assessed following a single-dose. The clinical data were assessed following a single dose administration.
Methods for producing the compositions and dosage forms (in particular the tablets of the disclosure) described herein are also provided. A tablet can be made by compression or molding, optionally with one or more excipients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with excipients. In general, tableting methods are well known in the art of pharmacy. Techniques and formulations generally are found in Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, PA), which is hereby incorporated by reference herein in its entirety.
In some embodiments, the method comprises blending bictegravir and lenacapavir (or their pharmaceutically acceptable salts) with excipients, followed by compression.
In some embodiments of forming a monolayer tablet according to the disclosure, bictegravir and lenacapavir (or their pharmaceutically acceptable salts) are first co-blended with excipients and granulated, for example by dry granulation. This step involves, in certain embodiments, roller compaction and/or milling. In some embodiments, the granulation of the co-blended bictegravir and lenacapavir (or their pharmaceutically acceptable salts) are further combined with extragranular excipients, including but not limited to magnesium stearate, then compressed.
In some embodiments a multilayer tablet (e.g. a bilayer tablet) is produced, the method comprising (a) compressing the bictegravir or a pharmaceutically acceptable salt thereof with excipients as a first layer, and (b) compressing lenacapavir or a pharmaceutically acceptable salt thereof with excipients to form a second layer. The first layer and second layer may be compressed separately and subsequently combined. In some embodiments, the first layer is formed by compression and subsequently the second layer is compressed onto the first layer.
In some embodiments a multilayer tablet (e.g. a bilayer tablet) is produced, the method comprising (a) compressing the lenacapavir or a pharmaceutically acceptable salt thereof with excipients as a first layer, and (b) compressing bictegravir or a pharmaceutically acceptable salt thereof with excipients to form a second layer. The first layer and second layer may be compressed separately and subsequently combined. In some embodiments, the first layer is formed by compression and subsequently the second layer is compressed onto the first layer.
In some embodiments, lenacapavir or a pharmaceutically acceptable salt thereof is spray dried prior to further formulation to form a lenacapavir dispersion including one or more excipients. In some embodiments, a lenacapavir dispersion is obtained by spray drying a mixture comprising lenacapavir or a pharmaceutically acceptable salt thereof and one or more excipients in a suitable solvent. Solvents suitable for spray-drying can be any organic solvent in which lenacapavir or a pharmaceutically acceptable salt thereof is miscible. The solvent should have relatively low toxicity and be removed from the dispersion to a level that is acceptable according to The International Committee on Harmonization (ICH) guidelines. Removal of solvent to this level may require a post drying step such as for instance tray-drying, subsequent to the spray-drying process. Solvents include alcohols such as methanol, ethanol, n-propanol, iso-propanol, and butanol, in particular methanol; ketones such as acetone, methyl ethyl ketone and methyl iso-butyl ketone; esters such as ethyl acetate and propylacetate; and various other solvents such as acetonitrile, dichloromethane, toluene, and 1,1,1-trichloroethane. Lower volatility solvents such as dimethyl acetamide or dimethylsulfoxide can also be used.
The lenacapavir dispersion may be blended and granulated with bictegravir or a pharmaceutically acceptable salt thereof, optionally with excipients. This step may be done by roller compaction and/or milling. In some embodiments, the step is done by roller compaction. The co-blended bictegravir and lenacapavir granules are further combined with extragranular excipients, then compressed to form a monolayer tablet. In some embodiments, the excipient is magnesium stearate.
In some embodiments, a bilayer tablet is produced. Prior to the production of the tablet, the lenacapavir or a pharmaceutically acceptable salt thereof is generally spray dried with one or one or more excipients to form a lenacapavir dispersion. The lenacapavir dispersion may be blended and granulated with additional excipients. This step may be done by roller compaction and/or milling. In some embodiments, this step is done by milling. The lenacapavir granules are further combined with extragranular excipients (in some embodiments magnesium stearate). Separately, when producing a bilayer tablet of the present disclosure, the bictegravir or a pharmaceutically acceptable salt thereof is blended with excipients and granulated (in some embodiments using roller compaction). In some embodiments, the bictegravir granules are then compressed as a first layer and subsequently, the lenacapavir granules are compressed as a second layer to form a bilayer tablet. In some embodiments, the lenacapavir granules are then compressed as a first layer and subsequently, the bictegravir granules are compressed as a second layer to form a bilayer tablet. The first layer and second layer may be compressed separately and subsequently combined. In some embodiments, the first layer is formed by compression and subsequently the second layer is compressed onto the first layer. In some embodiments, the resulting bilayer tablet is coated with a film coating. In some embodiments, this tablet is coated with a non-functional coating.

The bictegravir/lenacapavir (BIC/LEN) bilayer tablets were manufactured through a series of unit operations as summarized in the manufacturing process flow diagram of
First lenacapavir sodium and excipients in solution were spray dried and then secondary dried to form lenacapavir spray-dried dispersion. Lenacapavir spray-dried dispersion was blended with intragranular excipients, then milled/dispersed. The mixture was blended with a portion of the lubricant, roller compacted, and milled. The resulting granules were then blended with the remainder of the lubricant to yield the LEN final blend for compression.
Bictegravir sodium was blended with intragranular excipients, then milled/dispersed. The mixture was blended with a portion of the lubricant, roller compacted, and milled. The resulting granules were then blended with the remainder of the lubricant to yield the BIC final blend for compression.
BIC and LEN final blends were compressed into bilayer tablets to yield the BIC/LEN tablet cores, which were film-coated yellow and packaged.
The dissolution of bictegravir in biorelevant media was determined as a function of time. A single tablet was placed in 250 mL of 3.75 mM Fasted-State Simulated Intestinal Fluid (FaSSIF) pH 6.5 (3 mM taurocholate, 0.75 mM lecithin, 0.10 M NaCl) pre-heated to 37° C. and stirring at 75 rpm. Samples (10 mL) were taken at pre-determined timepoints of 0, 5, 10, 15, 20, 30, 45, 60, and 120 minutes. The withdrawn media was immediately replaced with 10 mL of fresh media. Each sample was filtered through a 0.22 μm PES filter (Millex—GP Fast Flow & Low Binding Millipore Express), discarding the first ˜8 mL of filtrate. The remaining filtrate was transferred to an amber vial for direct analysis using an appropriate UPLC-UV method.
The dissolution of bictegravir from 75/25 mg BIC/LEN monolayer (M1) and bilayer (B1) tablets was compared to the dissolution of bictegravir from the combination of the comparative single agent tablets of 75 mg BIC (C1) and 25 mg LEN (C2). The results are shown in
The dissolution of bictegravir from 75/50 mg BIC/LEN monolayer (M2) and bilayer (B2) tablets was compared to the dissolution of bictegravir from the combination of the comparative single agent tablets of 75 mg BIC (C1) and 50 mg LEN (C3). The results are shown in
The dissolution of lenacapavir in relevant media was determined as a function of time. Multiple tablets (number of tablets determined such that 300 mg of lenacapavir was added to the system) were placed in 900 mL of 2% w/w Cremophor EL in 30 mM potassium phosphate pH 6.0 pre-heated to 37° C. and stirring at 75 rpm. Samples (10 mL) were taken at pre-determined timepoints of 0, 10, 15, 20, 25, 30, 45, 60, and 120-125 minutes. Each sample was filtered through a 0.22 μm PES filter (Millex—GP Fast Flow & Low Binding Millipore Express), discarding the first ˜8 mL of filtrate. The remaining filtrate was transferred to an amber vial for direct analysis using an appropriate UPLC-UV method.
The dissolution of lenacapavir from 75/25 mg BIC/LEN monolayer (M1) and bilayer (B1) tablets was compared to the dissolution of lenacapavir from the combination of comparative single agent tablets of 75 mg BIC (C1) and 25 mg LEN (C2). The results are shown in
The dissolution of lenacapavir from 75/50 mg BIC/LEN monolayer (M2) and bilayer (B2) tablets was compared to the dissolution of lenacapavir from the combination of comparative single agent tablets of 75 mg BIC (C1) and 50 mg LEN (C3). The results are shown in
These results demonstrate that LEN release from 75/25 mg BIC/LEN monolayer tablets is significantly reduced relative to the combination of 75 mg BIC and 25 mg LEN single agent tablets. However, increasing the amount of lenacapavir from 25 mg to 50 mg in BIC/LEN monolayer tablets that contain 75 mg bictegravir provides comparable LEN dissolution to that observed for comparative 75 mg BIC and 50 mg LEN single agent tablets.
The PK properties of bictegravir and lenacapavir in monolayer and bilayer tablets of the disclosure was compared to that arising from the combination of tablets comprising the single agents using the method below.
Each dosing group consisted of 6 male, non-naive purebred beagle dogs. At dosing, the animals weighed between 6 to 13 kg. The animals were fasted overnight prior to dose administration and up to 4 hr after dosing. Each subject was pre-treated with pentagastrin (6 μg/kg) and dosed 30 minutes later with a tablet(s) containing 75 mg of bictegravir and 25 or 50 mg of lenacapavir. Each subject was given 5 mL of water to aid in swallowing followed by an additional 25 mL of water for a total of 30 mL water administered with each dose.
Serial venous blood samples (approximately 1 mL each) were taken from each animal at 0, 0.25, 0.50, 1.0, 2.0, 4.0, 6.0, 8.0, 12.0, 24.0, 48.0, 72.0, 96.0, and 120.0 hours after dosing. The blood samples were collected into Vacutainer™ tubes containing K2EDTA as the anti-coagulant and were immediately placed on wet ice pending centrifugation for plasma. An LC/MS/MS method was used to measure the concentration of the test compound in plasma. An aliquot of 20 μL of each plasma sample was added to a clean 96 well plate, and 120 μL of 50 nM GS-833737 and 100 ng/mL Carbamazepine in acetonitrile (ACN) was added. After protein precipitation, an aliquot of 100 μL of the supernatant was transferred to a clean 96-well plate and diluted with 100 μL of water. An aliquot of 0.5-1.5 μL of the above solution was injected into a Applied Biosystems API-6500 LC/MS/MS system. A Waters Acquity UPLC system with sample organizer was used for sample injection, elution, and separation. An API-6500 triple quadrupole mass spectrometer was utilized in multiple reaction monitoring mode (Sciex, Framingham, MA).
For analysis of bictegravir concentration, the system utilized a Waters HSS T3 UPLC column (50×2.1 mm, 2.5 μm). Liquid chromatography was performed using two mobile phases: mobile phase A contained 100/0.1 v/v % water/formic acid and mobile phase B contained 100/0.1 v/v % acetonitrile/formic acid.
For analysis of lenacapavir concentration, the system utilized a Waters BEH C8 UPLC column (50×2.1 mm, 1.7 μm). Liquid chromatography was performed using two mobile phases: mobile phase A contained 50/25/25/0.1 v/v % water/acetonitrile/methanol/formic acid and mobile phase B contained 50/50/0.1 v/v % acetonitrile/methanol/formic acid.
Non-compartmental pharmacokinetic analysis was performed on the plasma concentration-time data. F (%) refers to oral bioavailability; AUClast refers to area under the curve from time zero to the last quantifiable concentration and is a measure of total plasma exposure of the indicated compound; Cmax refers to the peak plasma concentration of the compound after administration.

The PK properties in human subjects of bictegravir and lenacapavir in monolayer tablets of the disclosure was compared to that arising from the combination of tablets comprising the individual agents using the method below.
The study was done by a Phase-1, open-label, multicenter, single-dose, multiple-cohort, parallel study in healthy participants to evaluate the relative bioavailability of BIC/LEN fixed-dose combination tablets. Following completion of screening and assessments, eligible participants were administered study drug(s) on Day 1 as described below:
Cohort 1: Single doses of 1×C1 (BIC 75 mg tablet) and 1×C2 (LEN 25 mg tablet) administered simultaneous, orally under fasted conditions.
Cohort 2: Single dose of 1×M1 (BIC/LEN 75/25 mg monolayer tablet) administered orally under fasted conditions.
Cohort 5: Single dose of 1×M2 (BIC/LEN 75/50 mg monolayer tablet) administered orally under fasted conditions.
Cohort 6: Single dose of 1×M4 (BIC/LEN 75/100 mg monolayer tablet) administered orally under fasted conditions.
Cohort 7: Single dose of 1×B1 (BIC/LEN 75/25 mg bilayer tablet) administered orally under fasted conditions.
All study treatments were administered orally at the study site in the morning at approximately the same time each day with 240 mL of water. The study drug(s) were administered in the morning following an overnight fast (no food or drink, except water, for at least 10 hours). Participants were restricted from food intake until after collection of the 4-hour postdose blood draw. Additionally, participants were restricted from water consumption 1 hour before and until 2 hours after dosing, except for the 240 mL of water given with the study treatment(s). A meal (standardized lunch) was provided to the participants after the 4-hour postdose blood draw.
Eligible participants were confined to the study centre beginning Day −1 until the completion of assessments on Day 8.
For each cohort, plasma concentrations and relevant PK parameters of BIC and LEN were listed and summarized using descriptive statistics (as applicable). Two-sided 90% CIs were calculated for the ratios of geometric least-squares means (GLSMs) between test and reference treatments being compared.
The PK properties of bictegravir from the evaluated tablets are shown in the table below and in
aAUCinf was excluded for 1 participant in Cohort 2 because area extrapolated from last available time point to infinity was more than 20% of the total AUCinf
The PK properties of lenacapavir from the evaluated tablets are shown in the table below and in
aAUCinf was excluded for 11, 16, 2, 9 and 3 participants in Cohorts 1, 2, 5, 6 and 7, respectively, because area extrapolated from the last available time point to infinity was more than 20% of the total AUCinf.
bT1/2 was excluded for 1, 4, and 2 participants in Cohorts 1, 2, and 6, respectively, because the Rsq adjusted valu for the regression line was >0.8.
The results demonstrate that the Cmax, AUCinf and AUClast of bictegravir from the 75/100 mg BIC/LEN monolayer tablet (M4) was reduced relative to the combination of 75 mg BIC+25 mg LEN single agent tablets (C1+C2).
Additionally, the results demonstrate that AUC0last of lenacapavir from the 75/25 mg BIC/LEN monolayer tablet (M1) was reduced relative to the co-administration of 75 mg BIC+25 mg LEN (C1+C2). In contrast, the AUClast of lenacapavir from the 75/50 mg BIC/LEN monolayer tablet (M2) was superior (about 2- to 2.4-fold higher) relative to administration of 25 mg LEN as a single agent (C2).

The impact of the choice of filler in the 75 mg bictegravir layer of the bilayer BIC/LEN bilayer tablet formulation was evaluated. Bilayer tablets comprising 75/25 mg BIC/LEN and 75/50 mg BIC/LEN were manufactured in which the bictegravir layer composition was varied as summarized in the table below. The lenacapavir layer compositions were manufactured having the same composition as C2 (for the 75/25 mg BIC/LEN tablets) and C3 (for the 75/50 mg BIC/LEN tablets).

First lenacapavir sodium and excipients in solution were spray dried and then secondary dried to form lenacapavir spray-dried dispersion. Lenacapavir spray-dried dispersion was blended with intragranular excipients, then milled/dispersed. The mixture was blended with a portion of the lubricant, roller compacted, and milled. The resulting granules were then blended with the remainder of the lubricant to yield the LEN final blend for compression.
Bictegravir sodium was blended with intragranular excipients, then milled/dispersed. The mixture was blended with a portion of the lubricant, roller compacted, and milled. The resulting granules were then blended with the remainder of the lubricant to yield the BIC final blend for compression.
BIC and LEN final blends were compressed into bilayer tablets to yield the BIC/LEN tablet cores.
The resulting BIC layers were evaluated across a number of manufacturing parameters, the results of which are shown in the table below:
bSticking/filming evaluation was performed on the individual BIC blend prior to compression. The sticking/filming evaluation was done with at least 1300 hits on Korsch XL-100; 1.5% EG Mg St only 500 hits on Korsch XL-100; 2:1 and 1:1 Mannitol:MCC only evaluated on Compaction Simulator (CS); stable filming did not accumulate or worsen over the course of the experiment.
cEjection force evaluation was performed on the final BIC/LEN tablet (i.e. after combining the BIC and LEN layers).
dDelamination evaluation was performed on the final BIC/LEN tablet (i.e. after combining the BIC and LEN layers). The delamination was evaluated on hardness testing; run on CS mimicking XL-400, n = 3 tablets/force. Minimal is up to 1/3 tablets/force across target roller compaction range.
eBlend properties evaluation was performed on the individual BIC blend prior to compression. The blend properties evaluation included compressibility profiles, tensile strength, flow, permeability, density, and particle size distribution.
The results show that the use of 100% Intragranular MCC and 100% Intragranular MCC+0.5% Extragranular Mg St provided BIC layers (K4 and K5) that were stable to filming, required low ejection forces and had acceptable blend properties. In contrast, the use of mannitol:MCC filler mixes (K1, K2, and K3) led to major sticking or filming in the tested formulations.
