- Example 1 Quadruple Combination Composition Therapy (Quadpill) for the Treatment of Hypertension
- the Quadpill study was a randomized, placebo-controlled, double-blind cross-over trial. The study was divided into three phases ( FIG. 1 ). During the first phase (4 weeks) participants were randomized (1:1) to either receive Quadpill or Placebo. This was followed by a two week washout (placebo) and subsequently participants were crossed over to the opposite arm to receive the other treatment for four weeks ( FIG. 1 ). Participants were recruited from the community, predominantly through community general practices in western Sydney, Australia.
- Participants were eligible if they met the following inclusion criteria: 1) adults aged 18 years and over, 2) office SBP>140 mmHg and/or DBP>90 mmHg on 2 readings on separate days; plus baseline ambulatory SBP>135 and/or DBP>85; 3) Not on medical treatment for hypertension.
- Exclusion criteria included: No definite contraindication to one or more component medications in the Quadpill; the responsible clinician felt a change in current therapy would place the patient at risk; severe or accelerated hypertension; pregnancy; inability to provide informed consent; and medical illness with anticipated life expectancy less than 3 months.
- the Quadpill was a single encapsulated pill containing the four following components in the specified amounts: irbesartan (37.5 mg), amlodipine beyslate (1.25 mg), hydrochlorothiazide (6.25 mg) and atenolol (12.5 mg).
- the placebo capsule appeared identical and contained four placebo tablets of similar weight to those in the Quadpill.
- Participants were administered a single pill, Quadpill or placebo, throughout the trial. Patients were instructed to take the tablets at the same time each day and encouraged to take this in the morning, but the time of the day (morning or evening) was at the patient's preference.
- a computer assisted randomization sequence was generated by a statistician and supplied to the pharmaceutical packaging company.
- the research assistant, recruitment team, investigators were blinded to this sequence.
- the pills were packaged into three child-resistant packs corresponding to three phases of the study. All packs had identical appearance ensuring blinding of patient and research staff. Subsequently the medication packs were prescribed in an organized sequence.
- the primary outcome was reduction in mean 24 hour systolic blood pressure at 4 weeks using ambulatory blood pressure monitoring (ABP).
- Drug acceptability and tolerability were also assessed at the end of the study. All adverse events were recorded. In addition, clinical adverse events possibly associated with blood pressure lowering medications: dizziness, blurred vision, syncope/collapse, chest pain/angina, shortness of breath, cough, wheeze, pedal oedema, skin rash, itching were specifically asked about.
- the trial had a simplified data safety and management committee of two core members with expertise in clinical medicine, trials and statistics. A single meeting was convened when 10 patients were randomized to the trial to review safety, and the study was advised to continue.
- the study ended at one year at the end of the budget and staffing time allocated and the original sample size was not reached.
- Quadpill a capsule containing four BP lowering components—reduced 24 hr ambulatory SBP by 18 mmHg and achieved office BP ⁇ 140/90 mmHg in 100% of participants. This trial illustrates some of the potential advantages of an approach that uses multiple drugs at very low doses to achieve efficacy.
- creatinine and urate were observed in this trial, with no patient experiencing more than a 12% increase.
- the increase in creatinine may not be of clinical importance, as creatinine is affected not only by kidney function, but also by renal, especially glomerular, perfusion which can be reversibly reduced systemically or locally. Both approaches reduce the risk of kidney failure in people with increased intraglomerular pressure (manifested clinically as proteinuria), despite reversibly increasing creatinine levels.
- a creatinine effect of BP lowering is therefore to be expected, may not indicate long term renal harm, and could lead to renal benefit for the participants with raised intraglomerular pressure and proteinuria.
- the primary objective of this study is to investigate in a double blind randomized controlled trial whether initiating treatment with a quadruple combination therapy will lower blood pressure more effectively, and with fewer side effects, compared to initiating standard dose monotherapy as per current guidelines in patients with hypertension.
- the secondary objective is to assess if this approach is safe and has fewer side effects compared to standard care.
- the primary outcome will be reduction in mean systolic blood pressure using standardized automated BP cuff at 12 weeks. Secondary outcomes will include: proportion with controlled blood pressure at 6 weeks, 12 weeks, ambulatory blood pressure (ABP) measures and tolerability/occurrence of adverse events.
- a combination pill comprising the following four components—irbesartan (37.5 mg), amlodipine besylate (1.25 mg), indapamide (0.625 mg), bisoprolol fumarate (2.5 mg); or 2) irbesartan (150 mg).
- the primary outcome will be the difference between groups in mean automated office systolic blood pressure at 12 weeks adjusted for baseline values.
- the secondary outcomes include the following:
- SBP systolic blood pressure
- ANCOVA analysis of covariance
- Additional analyses will include both 6-week and 12-week measurements in a longitudinal model including treatment arm, visit, and treatment by visit interaction as well as the baseline measurement.
- Within-patient correlations will be modelled using generalized estimating equations.
- binary endpoints e.g. hypertension control
- log-binomial regression used in place of linear regression.

Abstract
Description
- This application is a continuation of U.S. application Ser. No. 15/352,425, filed Nov. 15, 2016, the content of which is hereby incorporated in its entirety.
- High blood pressure, also known as hypertension, is a leading cause of preventable morbidity and mortality and it is well established that treatments that lower blood pressure (BP) are beneficial. However, despite the plethora of blood pressure lowering medicines available, many patients continue to have poor blood pressure control as evidenced by multiple large-scale population studies. Contributing factors for poor blood pressure control include poor adherence, complex guidelines recommending multiple up-titration steps, and treatment inertia. Furthermore, the majority of treated patients receive only monotherapy, which has limited potency even at high doses where side effects are increased and tolerability reduced. Accordingly, there exists a need for new treatments for lowering high blood pressure that are efficacious and tolerable.

- Exemplary pharmaceutical compositions may be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which includes one or more of a disclosed compound, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of the disease.
- For preparing solid compositions such as tablets, the principal active ingredient may be mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g., water, to form a solid preformulation composition containing a homogeneous mixture of a disclosed compound or a non-toxic pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
- In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules and the like), the subject composition is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.
- A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the subject composition moistened with an inert liquid diluent. In some embodiments, capsules are prepared by encapsulating tablets in hard-gelatin capsules (e.g. overencapsulation.) Tablets, and other solid dosage forms, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art.

- The Quadpill study was a randomized, placebo-controlled, double-blind cross-over trial. The study was divided into three phases (
FIG. 1 ). During the first phase (4 weeks) participants were randomized (1:1) to either receive Quadpill or Placebo. This was followed by a two week washout (placebo) and subsequently participants were crossed over to the opposite arm to receive the other treatment for four weeks (FIG. 1 ). Participants were recruited from the community, predominantly through community general practices in western Sydney, Australia. - Participants were eligible if they met the following inclusion criteria: 1) adults aged 18 years and over, 2) office SBP>140 mmHg and/or DBP>90 mmHg on 2 readings on separate days; plus baseline ambulatory SBP>135 and/or DBP>85; 3) Not on medical treatment for hypertension. Exclusion criteria included: No definite contraindication to one or more component medications in the Quadpill; the responsible clinician felt a change in current therapy would place the patient at risk; severe or accelerated hypertension; pregnancy; inability to provide informed consent; and medical illness with anticipated life expectancy less than 3 months.
- The Quadpill was a single encapsulated pill containing the four following components in the specified amounts: irbesartan (37.5 mg), amlodipine beyslate (1.25 mg), hydrochlorothiazide (6.25 mg) and atenolol (12.5 mg). The placebo capsule appeared identical and contained four placebo tablets of similar weight to those in the Quadpill.
- Participants were administered a single pill, Quadpill or placebo, throughout the trial. Patients were instructed to take the tablets at the same time each day and encouraged to take this in the morning, but the time of the day (morning or evening) was at the patient's preference.
- All trial medicines were prepared by a TGA-cGMP (Therapeutic Goods Australia-certificate of Good Manufacturing Practice) licensed manufacturing facility. Low strength doses were obtained by halving half-strength doses using a pill splitting device, without crushing, and were weighed to ensure accuracy of halving doses. The low strength doses were than encapsulated using gelatin capsules (DBCaps—Capsugel). The capsules were stored in a cool dry place and monitored using temperature loggers, until they were dispensed.
- Treatment allocations were blinded to both study staff and participants. In addition to the study drugs, all participants were offered education on healthier lifestyle options as recommended by guidelines for hypertension management.
- A computer assisted randomization sequence was generated by a statistician and supplied to the pharmaceutical packaging company. The research assistant, recruitment team, investigators were blinded to this sequence. For each patient i.e. allocated randomization number, the pills were packaged into three child-resistant packs corresponding to three phases of the study. All packs had identical appearance ensuring blinding of patient and research staff. Subsequently the medication packs were prescribed in an organized sequence.
- The primary outcome was reduction in mean 24 hour systolic blood pressure at 4 weeks using ambulatory blood pressure monitoring (ABP). The secondary outcomes included:
-
- a. Reduction in mean 24 hour diastolic blood pressure, and in daytime and nighttime SBP and DBP at 4 weeks
- b. Reduction in office SBP and DBP as measured by a standardized automated blood pressure cuff
- c. Proportion with controlled blood pressure at 4 weeks, defined as <135/85
mmHg 24 hour BP and <140/90 mmHg office BP - d. Adverse events and pre-specified adverse events by laboratory parameters: Rise in transaminases (ALT/AST) more than 3× upper limit of normal or doubling if baseline levels known to be elevated; drop in estimated glomerular filtration rate by >20% as estimated from serum creatinine; sodium, potassium and uric acid levels
- e. Assessment of acceptability and tolerability
- Patients underwent 24
hour ABP monitoring 4 times—baseline (off study drug), 4 weeks (on phase 1 drug), 6 weeks (on placebo) and 10 weeks (onphase 3 drug). In order to minimize inconvenience, patients were referred for ABP to a lab. The ABP units were calibrated at regular intervals by the lab according to the manufacturer's specification. To minimize variability, the follow up readings were repeated from the same collection center using the same brand device. Participants were reimbursed nominal amounts to cover travel and parking costs. Study medications and investigations were provided at no cost to participants. Office BP was recorded three times at each visit using an OMRON T9P (HEM-759-C1). The second and the third readings were averaged for study analysis. In addition atweek - Drug acceptability and tolerability were also assessed at the end of the study. All adverse events were recorded. In addition, clinical adverse events possibly associated with blood pressure lowering medications: dizziness, blurred vision, syncope/collapse, chest pain/angina, shortness of breath, cough, wheeze, pedal oedema, skin rash, itching were specifically asked about.
- The trial had a simplified data safety and management committee of two core members with expertise in clinical medicine, trials and statistics. A single meeting was convened when 10 patients were randomized to the trial to review safety, and the study was advised to continue.
- A sample size of 50 patients was planned to provide 90% power at p=0.05 to detect a SBP difference of 12 mmHg between the intervention and control assuming a SD of the within patient difference of 12 mmHg, taking into account the possibility of a 10% loss to follow-up. The study ended at one year at the end of the budget and staffing time allocated and the original sample size was not reached.
- Analyses were conducted on an intention to treat basis. All tests were two-sided and the nominal level of α was 5%. All statistical analyses were unadjusted for prognostic covariates. We reported compliance to the study drug using data on pills (doses) taken and missed doses over the time period.
- A linear mixed model was used to estimate the effect of the treatment on change in blood pressure from baseline for each treatment period, according to the Kenward and Roger approach (Kenward M G, Roger J H. The use of baseline covariates in crossover studies. Biostatistics 2010; 11(1): 1-17.) In order to appropriately adjust for baseline levels, collected at the beginning of each treatment period (
week 0, week 6), this method uses all measurements (baseline and follow-up, in both period) as outcomes, but accounts for covariance between measurements within individuals (Liu G F, Lu K, Mogg R, Mallick M, Mehrotra D V. Should baseline be a covariate or dependent variable in analyses of change from baseline in clinical trials? Stat Med 2009; 28(20): 2509-30). A linear contrast between the variables denoting period (first/second), type of measurement (baseline/final), and treatment received (placebo/Quadpill) produces an unbiased estimate of effect of the Quadpill on change in blood pressure compared to the placebo. All available data were included in the model, no missing data was imputed. If a patient had missing data for one period, data from the available period were used. A sensitivity analysis was carried including only patients with data available from both periods to see if the effect of treatment is modified. There was also adjustment of the denominator degrees of freedom of Kenward and Roger (2009) that is optimal for smaller sample sizes (Kenward M G, Roger J H. An improved approximation to the precision of fixed effects from restricted maximum likelihood. Computational Statistics & Data Analysis 2009; 53(7): 2583-95). - Testing for carry over used an unpaired t-test of the main outcome with order as an effect. Period effect was tested by using a paired t-test comparing the main outcome in period 1 with main outcome in
period 2 from the same patient. A sensitivity analysis was also performed using normal paired t-test to compare primary outcome between different period (different treatment) from the same patient, ignoring the baseline level of each period. - Continuous secondary endpoints with baseline values (e.g. daytime/night-time ambulatory SBP/DBP) were analyzed similarly to the primary endpoint. Other continuous variables without a baseline value in each period were analyzed with a paired t-test. Counts and percentages of all adverse events were reported. As a sensitivity analysis, the analyses were repeated on the 18 complete-cases (i.e. full data for each measurement period) data and showed similar findings to those reported here.
- Tests for interaction of treatment effect with age (<=60 vs. >60 years), gender, and BMI (<=30 vs. <30 kg/m2). Subgroup analyses for each variable were also conducted. All analyses were conducted using SAS 9.4 (Cary, N.C., USA) on software.
- Of 55 patients screened, 21 participants were eligible, one patient declined prior to drug initiation. Twenty were randomised between November 2014 and December 2015 and two withdrew at the end of the first treatment period because of social reasons (
FIG. 2 ) Baseline characteristics of the study population are shown in Table 1. -

(Table 2) The placebo-corrected reduction in mean 24 hour SBP/DBP was 22/15 mmHg during the day time and 10/12 mmHg overnight. Office SBP was reduced by 22.4 mmHg, 95% CI 16.5-28.3 and DBP by 13.1 mmHg, 95% CI 8.8-17.3. Overall 15/18 (83%) participants achieved a mean ambulatory SBP<135 and DBP<85 mmHg when taking the Quadpill, compared to 7/18 (39%) when taking placebo (p=0.0053). All participants achieved an office SBP<140 and DBP<90 mmHg on the Quadpill compared to 6/18 (33%) on placebo (p=0.0013). (Table 3) The mean pulse rate was lower on Quadpill treatment (difference between group of −6.5 beats per minute (−10.6, −2.3).

There were no significant interactions by age, sex or BMI. In sensitivity analysis using a standard comparison (paired t-test), results were virtually identical with a difference in mean 24-hour SBP between the Quadpill and placebo periods of −18.7 mmHg, 95% CI −23.1; −14.2. Similarly in a second sensitivity analysis that included only patients with complete data (n=18) from both periods, results were also virtually identical with the difference in mean 24-hour SBP of −18.7, 95% CI −23.2; −14.2.
- Compliance with therapy was high. The mean number of tablets missed in the last week was 0.2 (SD 0.4) for Quadpill and 0.3 (SD 0.6) for placebo. All 18 participants who finished the study completed the end-of-study acceptability questionnaire, with all reporting the study medication was either very easy (n=13) or easy (n=5) to swallow. In addition, all 18 participants reported it was either very likely (n=10) or likely (n=8) they would take the Quadpill if available commercially.
- There were no serious adverse events. One patient reported dizziness while on the Quadpill causing temporary discontinuation of treatment; one patient reported vestibular dizziness during the washout period on placebo; and one patient reported urinary frequency in Quadpill and placebo phases (Table 4). Mean creatinine levels were higher at the end of the Quadpill than the placebo treatment periods: creatinine 78 mmol/L (SD 14) vs 71 (SD 14), p=0.02; as were urate levels: 0.4 (0.1) vs 0.3 (0.1), p=0.003. (Table 5) The absolute changes in creatinine (4.4, 95% CI 0.9-7.8)) and urate (0.03, 95% CI 0.001-0.04) were small, (no patient had more than a 12% increase in either variable) and appeared reversible (e.g. for those who received Quadpill first, the mean creatinine was x, y and z at baseline, 4 weeks and 10 weeks, respectively) There were no significant differences in ALT, AST, Sodium, potassium, total cholesterol or LDL-cholesterol.

This trial illustrates some of the potential advantages of an approach that uses multiple drugs at very low doses to achieve efficacy.
- Small but statistically significant increases in creatinine and urate were observed in this trial, with no patient experiencing more than a 12% increase. The increase in creatinine may not be of clinical importance, as creatinine is affected not only by kidney function, but also by renal, especially glomerular, perfusion which can be reversibly reduced systemically or locally. Both approaches reduce the risk of kidney failure in people with increased intraglomerular pressure (manifested clinically as proteinuria), despite reversibly increasing creatinine levels. A creatinine effect of BP lowering is therefore to be expected, may not indicate long term renal harm, and could lead to renal benefit for the participants with raised intraglomerular pressure and proteinuria. The findings present for the first time placebo-controlled data that ultra-low dose multi-drug combination therapy can be very effective in BP lowering, even for previously untreated patients with very mildly elevated blood pressure levels. This justifies further trials on long-term efficacy and safety, both for initial treatment and among patients with inadequate control and/or side effects while receiving monotherapy.
- The primary objective of this study is to investigate in a double blind randomized controlled trial whether initiating treatment with a quadruple combination therapy will lower blood pressure more effectively, and with fewer side effects, compared to initiating standard dose monotherapy as per current guidelines in patients with hypertension. The secondary objective is to assess if this approach is safe and has fewer side effects compared to standard care.
- This will be a 12-week double blind randomized controlled trial (1:1) of 650 patients with
grade 1 and 2 essential hypertension. Subjects will be randomized through a central computer-based randomization service, to initial therapy with the quadruple combination composition or to an angiotensin receptor blocker (ARB), with option to add a calcium channel blocker (CCB) as required, as per current Australian Hypertension guidelines. The primary outcome will be reduction in mean systolic blood pressure using standardized automated BP cuff at 12 weeks. Secondary outcomes will include: proportion with controlled blood pressure at 6 weeks, 12 weeks, ambulatory blood pressure (ABP) measures and tolerability/occurrence of adverse events. - The inclusion criteria are as follows:

- e. Difference between groups in the proportion of non-dippers (night-time BP is not more than 10% lower than average daytime BP as per NHFA Guide to management of hypertension 2008) and coefficient of variability of BP (O'Brien, E., G. Parati, and G. Stergiou, Hypertension, 2013. 62(6): p. 988-94).

- All analyses of study outcomes will be conducted according to the principle of intention-to-treat. The primary analysis of change in systolic blood pressure (SBP) at 12 weeks will be performed using an analysis of covariance (ANCOVA) including the treatment arm and baseline SBP as a covariate. Continuous secondary outcomes will be analyzed similarly. Additional analyses will include both 6-week and 12-week measurements in a longitudinal model including treatment arm, visit, and treatment by visit interaction as well as the baseline measurement. Within-patient correlations will be modelled using generalized estimating equations. A similar approach will be applied to binary endpoints (e.g. hypertension control) with log-binomial regression used in place of linear regression. There will also be pre-defined subgroup analyses, including by baseline blood pressure, gender, age and hypertension treatment history. A detailed analysis plan will be developed prior to unblinding.
