Most testosterone based pharmaceutical products on the market employ dose titration schemes to ensure that patients are safely (e.g., avoiding unacceptably high testosterone levels) and efficaciously treated (e.g., achieving typical eugonadal testosterone levels in hypogonadal patients). Dose titrations are typically required because different patients can absorb and metabolize testosterone based products in substantially different manners. A dose of a testosterone product for one patient that provides safe and efficacious testosterone levels may not provide safe and efficacious levels for another patient.
Disclosed herein is an oral testosterone therapy (“TT”) dosing regimen. In a specific aspect, the TT involves oral administration of a fixed daily dose of a testosterone ester. For example, where the testosterone ester is testosterone undecanoate (TU), a fixed dose within the range of 420-500 mg per day of oral TU is unexpectedly and particularly efficacious and safe for testosterone replacement therapy. In another example where the testosterone ester is TU, the fixed daily dose can be provided as 210-250 mg of oral TU twice per day for a total daily dose of 420-500 mg TU. Surprisingly, these fixed dose regimens require no dose titration to provide safe and efficacious serum testosterone levels to a substantial proportion of subjects (e.g., those needing testosterone replacement therapy). Thus, in some aspects, the fixed dose is provided as an oral pharmaceutical composition comprising a testosterone ester (e.g., testosterone undecanoate) and a pharmaceutically acceptable carrier, for once daily, or twice daily, etc. administration, with a meal, to a subject (e.g., a male having a condition associated with a deficiency or absence of endogenous testosterone). In some implementations, the daily dose is administered three times per day e.g., a 450 mg daily dose of testosterone undecanoate is administered as 150 mg three times a day or a 474 mg daily dose is administered as 158 mg three times a day.
In some embodiments, specific measures can be used to determine whether or not the therapy should continue or be discontinued. For example, biomarkers such as consistency of unacceptable testosterone (T) levels from a safety or efficacy standpoint, whether hematocrit levels rise above a threshold value, whether Prostate Specific Antigen (“PSA”) levels rise above a threshold value, or any other appropriate measure or marker can be used to determine whether or not the therapy should be discontinued.
Although the following detailed description contains many specifics for the purpose of illustration, a person of ordinary skill in the art will appreciate that many variations and alterations to the following details can be made and are considered to be included herein. Accordingly, the following embodiments are set forth without any loss of generality to, and without imposing limitations upon, any claims set forth. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “polymer” can include a plurality of such polymers.
As used herein, “AUC” refers to the area under the serum concentration-time curve
As used herein, “AUCt” refers to the area under the serum concentration-time curve from time zero to time of last measurable concentration.
As used herein, “Cavg” refers to average serum concentration over 24 hours.
As used herein, “Cmax” refers to maximum observed serum concentration per dose over dosing interval (or daily).
As used herein, “Tmax” refers to the time to maximum observed serum concentration.
As used herein, “TT” refers to testosterone therapy. In a specific definition, TT means any condition wherein serum testosterone is below the normal eugonadal range, such as 300 ng/dL when measured on two separate occasions in the morning. In another definition, the TT described herein can be used to treat patients that are eugonadal (or hypogonadal) for a condition other than specifically having testosterone levels lower than 300 ng/dL. In another specific definition, TT refers to testosterone replacement therapy e.g., to treat a condition associated with a deficiency or absence of endogenous testosterone.
As used herein, “T equivalent dose” from a TU dose is a testosterone equivalent dose that can be released from the bioreversible TU ester. For example, 158 mg of TU is equivalent to 100 mg of T.
As used herein, “Eugonadal range” is the typical range of serum testosterone found in patients not needing TT, normal eugonadal range, is defined as the range with an average testosterone lower limit of ˜300 ng/dL and average testosterone upper limit of 1000 ng/dL. It is understood that this normal range could vary depending on the testosterone assay utilized and variability among labs due to specific assay used by individual lab and patient demographics. Therefore, the lower limit of normal eugonadal range could also be 250 ng/dL. Similarly, the upper limit of normal eugonadal range could be 1040 or 1100, or 1500 ng/dL.
As used herein, “dosing regimen” or “administration regimen” can be used interchangeably and refer to specific dosing and administration of a TU containing product. In a specific embodiment, the dosing regimen typically entails daily dose, number of pills per dose, number of doses per day, and whether or not to take with food or fasting. The dosing regimen can also provide relevant instructions regarding the above, for healthcare providers and patients, in some embodiments. Some products (but not the product described herein) involve dose titration or a dose adjustment scheme, in patients needing adjustment, based on a patient's response to the product assessed via measured T measured T levels post dosing at steady state. A practical dosing regimen is the one that is easy to comprehend for implementation. The dosing regimen of this invention is a fixed dose dosing regimen for TT that does not need dose titration.
As used herein, “fixed dose” refers to the same (e.g. unchanging) daily dose of testosterone undecanoate being used for a given patient throughout a therapy regimen with no dose changes. “Single,” “singular” or “unitary” fixed dose means that the fixed dose is administered only once daily (e.g., one dose of 450 mg TU per day, one dose of 474 mg TU per day, etc., for example), which can be administered via one or more unit dosage forms during a common administration event or at a common administration time point. “No titration needed” (or “without titration”) means that, for a given patient, a fixed dose can provide suitable TT without the need to titrate the testosterone dosage for the patient. In some examples, “no titration needed” or “without titration” can mean that the fixed dose is not adjusted throughout the TT.
As used herein, “Discontinuation of TT” means the dosing regimen for the patient is unsuitable for TT and should be temporarily stopped until relevant markers (e.g., biomarkers, T levels, or any other suitable marker) improve or alternatively, it may be deemed that it is permanently unsuitable for TT in the patient. As used herein, “Consistently” refers to at least two or more times or occurrences as measured on two separate occasions with a least a gap of 24 hours preferably in the morning.
In this application, “comprises,” “comprising,” “containing” and “having” and the like can have the meaning ascribed to them in U.S. Patent law and can mean “includes,” “including,” and the like, and are generally interpreted to be open ended terms. The terms “consisting of” or “consists of” are closed terms, and include only the components, structures, steps, or the like specifically listed in conjunction with such terms, as well as that which is in accordance with U.S. Patent law. “Consisting essentially of” or “consists essentially of” have the meaning generally ascribed to them by U.S. Patent law. In particular, such terms are generally closed terms, with the exception of allowing inclusion of additional items, materials, components, steps, or elements, that do not materially affect the basic and novel characteristics or function of the item(s) used in connection therewith. For example, trace elements present in a composition, but not affecting the compositions nature or characteristics would be permissible if present under the “consisting essentially of” language, even though not expressly recited in a list of items following such terminology. When using an open ended term, like “comprising” or “including,” in this written description it is understood that direct support should be afforded also to “consisting essentially of” language as well as “consisting of” language as if stated explicitly and vice versa.
The terms “first,” “second,” “third,” “fourth,” and the like in the description and in the claims, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that any terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Similarly, if a method is described herein as comprising a series of steps, the order of such steps as presented herein is not necessarily the only order in which such steps may be performed, and certain of the stated steps may possibly be omitted and/or certain other steps not described herein may possibly be added to the method.
As used herein, “subject” or “patient” are used interchangeably and refer to a mammal that may benefit from the administration of a composition described herein. In one aspect the mammal may be a human.
As used herein, the terms “formulation” and “composition” are used interchangeably and refer to a mixture of two or more compounds, elements, or molecules. In some aspects the terms “formulation” and “composition” may be used to refer to a mixture of one or more active agents with a carrier or other excipients. Compositions can take nearly any physical state, including solid and/or liquid (i.e. solution). Furthermore, the term “dosage form” can include one or more formulation(s) or composition(s) provided in a form suitable for administration to a subject.
As used herein, “effective amount” refers to an amount of an ingredient which, when included in a composition, is sufficient to achieve an intended compositional or physiological effect. Thus, a “therapeutically effective amount” refers to a substantially non-toxic, but sufficient amount of an active agent, to achieve therapeutic results in treating or preventing a condition for which the active agent is known to be effective. It is understood that various biological factors may affect the ability of a substance to perform its intended task. Therefore, an “effective amount” or a “therapeutically effective amount” may be dependent in some instances on such biological factors. Additionally, in some cases an “effective amount” or a “therapeutically effective amount” may not be achieved in a single dose. Rather, in some examples, an “effective amount” or a “therapeutically effective amount” can be achieved after administering a plurality of doses over a period of time, such as in a pre-designated dosing regimen. Further, while the achievement of therapeutic effects may be measured by a physician or other qualified medical personnel using evaluations known in the art, it is recognized that individual variation and response to treatments may make the achievement of therapeutic effects a subjective decision. The determination of an effective amount is well within the ordinary skill in the art of pharmaceutical and nutritional sciences as well as medicine.
As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, a composition that is “substantially free of” particles would either completely lack particles, or so nearly completely lack particles that the effect would be the same as if it completely lacked particles. In other words, a composition that is “substantially free of” an ingredient or element may still actually contain such item as long as there is no measurable effect thereof.
As used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. Unless otherwise stated, use of the term “about” in accordance with a specific number or numerical range should also be understood to provide support for such numerical terms or range without the term “about”. For example, for the sake of convenience and brevity, a numerical range of “about 50 mg to about 80 mg” should also be understood to provide support for the range of “50 mg to 80 mg.” Furthermore, it is to be understood that in this written description support for actual numerical values is provided even when the term “about” is used therewith. For example, the recitation of “about” 30 should be construed as not only providing support for values a little above and a little below 30, but also for the actual numerical value of 30 as well.
As used herein, a plurality of items, structural elements, compositional elements, and/or materials may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary.
Concentrations, amounts, and other numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to about 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3, and 4 and sub-ranges such as from 1-2, from 1-3, from 1-4, from 2-3, from 2-4, from 2-5, from 3-4, and from 3-5, etc., as well as 1, 2, 3, 4, and 5, individually.
This same principle applies to ranges reciting only one numerical value as a minimum or a maximum. Furthermore, such an interpretation should apply regardless of the breadth of the range or the characteristics being described.
Reference in this application may be made to compositions, systems, or methods that provide “improved” or “enhanced” performance. It is to be understood that unless otherwise stated, such “improvement” or “enhancement” is a measure of a benefit obtained based on a comparison to compositions, systems or methods in the prior art. Furthermore, it is to be understood that the degree of improved or enhanced performance may vary between disclosed embodiments and that no equality or consistency in the amount, degree, or realization of improvement or enhancement is to be assumed as universally applicable.
Reference throughout this specification to “an example” means that a particular feature, structure, or characteristic described in connection with the example is included in at least one embodiment. Thus, appearances of the phrases “in an example” in various places throughout this specification are not necessarily all referring to the same embodiment.
It is noted that testosterone levels can be monitored via a variety of testosterone assays. Such testosterone assays (e.g., for serum testosterone, total testosterone, free testosterone etc.) can be performed as part of a diagnosis of hypogonadism, a treatment efficacy assessment, or discontinuation of therapy. The assays themselves can be radioimmunoassays via commercial kits, validated mass spectrometric methods, or any other suitable assay.
It is also noted that typical regulatory approval targets for TT are based on responder outcomes targeted for patients on TT such that average daily T levels (Cavg) are restored in the normal eugonadal range in at least 75% of the treated patients and no more than 15% of the patients experience maximum serum T concentrations (Cmax)>1500 ng/dL. Unacceptably high serum T level is typically defined as maximum serum concentrations of >1800 ng/dL observed in a patient post dosing in the dosing interval (or daily interval) is typically assessed by a percentage of patients in a group that shows Cmax>1800 ng/dL.
Described herein, in one embodiment, is a method of restoring testosterone levels in a patient needing testosterone therapy (TT). The method can include administering a therapeutically effective amount of a testosterone ester, such as testosterone undecanoate (TU), to the patient via an oral dosage form. The oral dosage form can be administered to the patient in a fixed dose dosing regimen. It is noted that for the sake of clarity and brevity, TU is generally referred to in this disclosure as an example testosterone ester. These references to TU are not intended to be particularly limiting unless otherwise specified. More broadly, references to TU can generally refer to any suitable testosterone ester.

Described herein, in one embodiment, is a method of restoring testosterone levels in a patient needing TT to within normal T levels while avoiding unacceptably high T levels. The method can include administering TU via an oral dosage form using a dosing regimen that does not need a dose adjustment or titration and that provides a daily amount of TU of about 430 mg.
In one embodiment, an unexpected finding of these studies, as outlined in the Examples and described herein, is the surprising discovery that a TT dosing regimen including an appropriate single fixed oral dose of TU in the range from 430 mg to 500 mg (or 430-480 mg) can obviate the need for a titration scheme or dose adjustment. This is unexpected since recent previous attempts to obtain regulatory approval of an oral TU based TT were based on dose titration schemes which were thought to be needed to ensure adequate efficacy and safety of the therapy. Additionally, many marketed TTs require dose titrations or adjustment as indicated on the product's label.
While any oral dosage form can be utilized in the dosing regimen of this invention for TT, in some examples the dosage form can be a capsule comprised of pharmaceutically acceptable components. In one embodiment, the dose of TU is 200-250 mg (e.g., 2 capsules of 100-125 mg TU or one capsule having about 200-250 mg TU) administered orally two times daily for a total daily dose of TU from 400-500 mg (T equivalent dose of approximately 250-316 mg/day). The oral dosage form can be administered with food (e.g., co-administered) having at least 10 g of fat, at least 15 g of fat, at least 20 g of fat, or at least 30 g of fat, or an amount of fat within the range of 10-60 g.
The dosing regimen of this invention can include a daily dose of TU administered as a four times per day (QID), a thrice per day (TID), a twice per day (BID), or a once per day (QD) dosage. Whatever the number of daily doses, each dose can be equally divided to provide a total daily dose of TU between 400-500 mg.
In one embodiment, the dose of testosterone undecanoate is 215-245 mg of testosterone undecanoate (e.g., 2 capsules of 107.5-122.5 mg) administered orally two times daily for a total daily dose of 430-490 mg.
Thus, in one embodiment, the dose of testosterone undecanoate can be 225 mg of testosterone undecanoate (e.g., one capsule of 225 mg, two capsules of 112.5 mg or three capsules of 75 mg) administered orally two times daily for a total daily dose of 450 mg.
In yet another embodiment, the dose of testosterone undecanoate can be about 237 mg of testosterone undecanoate (e.g., one capsule of 237 mg TU or e.g., two capsules adding up to 237 mg) administered orally two times daily for a total daily dose of 474 mg.
In some implementations of the methods and regimens described herein, a subject or patient can change from a twice daily regimen to a three times a day regimen or vice-versa.
The oral testosterone replacement therapy described herein was discovered to be safe and efficacious. For example, it is believed that the TT described herein meets (1), (2), (3), (4), and/or (5) of the following criteria when used in a sufficient population of individuals needing such therapy (e.g., hypogonadal men):
(1) Proportion of subjects with average serum T (Cavg) within the normal range
(e.g., 300-1000 ng/dL): ≥75%, 77%, 79%, 81%, 83%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94% or 95% or more;
(2) Proportion of subjects with average serum T (Cavg) within the normal range: ≥65%,
67%, 69%, 71%, 73%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84% or 85% or more with a lower bound 95% CI (Confidence Interval);
Proportion with maximum serum T (Cmax) outside the normal range:
(3) Cmax>1500 ng/dL (no greater than 15%, 16%, 17%, 18%, 19% 20%, 21%, 22%, 23%, 24% or 25%);
(4) Cmax between 1800 and 2499 ng/dL (no greater than 5% 6%, 7%, 8%, 9% or 10%); and
(5) Cmax≥2500 ng/dL (0%, or no greater than 1%, 2%, 3%, 4% or 5%).
In this context, a population of individuals typically refers to at least 20 individuals (e.g., in need of treatment like hypogonadal males) and preferable at least 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or 100 individuals or more.
In some embodiments, testosterone concentrations (e.g., blood, serum, or plasma) can be checked periodically, e.g., 3-8 hours after the morning dose, starting as soon as one month or two weeks (or sooner) after initiating treatment with testosterone undecanoate. When the total testosterone concentration consistently exceeds 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400 or 2500 ng/dL, therapy with testosterone undecanoate can be discontinued as advised by trained medical personnel (or in another alternative, the patient can switch to a three times a day regimen e.g., 450 mg daily dose can be switched from 225 mg twice a day to 150 mg three times a day). If the total testosterone concentration is consistently below 300 ng/dL, an alternative treatment can be considered as advised by trained medical personnel. As used in this paragraph, consistently can refer to two or more times or occurrences.
In another embodiment, testosterone (e.g., blood, serum, or plasma) concentrations can be checked periodically, e.g., any time between 3-8 hours after the morning dose, starting as soon as one month after initiating treatment with testosterone undecanoate. If the total testosterone concentration consistently exceeds 2500 ng/dL, therapy with testosterone undecanoate can be discontinued as advised by trained medical personnel (or in another alternative, the patient can switch to a three times a day regimen e.g., 450 mg daily dose can be switched from 225 mg twice a day to 150 mg three times a day or a 474 mg daily dose at 237 mg twice a day can be switched to 158 mg three times a day). If the total testosterone concentration is consistently below 300 ng/dL, an alternative treatment can be considered as advised by trained medical personnel. As used in this paragraph, consistently can refer to two or more times or occurrences.
In yet another embodiment, increases in hematocrit levels, reflective of increases in red blood cell mass, may require discontinuation of oral testosterone undecanoate. Hematocrit levels can be checked prior to initiating treatment. In some examples, it can be appropriate to re-evaluate the hematocrit levels starting from 3 months after starting treatment, and then annually. In some cases, if hematocrit levels become elevated, the therapy can be discontinued until hematocrit levels decrease to an acceptable level.

The dosage form from Example B of Composition 4 with dosing regimen (Regimen #9-16) of dosing category BID-equal dose with daily dose range 150-600 mg were used for a Clinic Study of Testosterone Therapy for hypogonadal males.
The clinical study was a randomized double-blind, placebo-controlled dose escalating study of the safety, efficacy, tolerability, and pharmacokinetics of testosterone therapy in hypogonadal males. This clinic study was a single and multiple, ascending-dose study that was designed to determine the optimal starting, titration (if appropriate), or single fixed dose for safety and efficacy targeted by the US FDA. The study also verified the time for testosterone levels to reach steady state and identified a suitable fixed dose dosing regimen that satisfies an unmet need for safety and efficacy for oral TT.
This study was carried out with conditions of a single-center, randomized, double-blind, placebo-controlled, ascending multiple-dose, and serial-group in adult hypogonadal male subjects. The objectives of this study were:
The following sections summarize the some relevant elements of the study and pertinent clinical pharmacology results.
The dosing regimen for this clinical study ranged from 150 mg daily dose (75 mg BID dose) to 600 mg daily dose (300 mg BID dose). Observed pharmacokinetic parameters (T, DHT, TU, DHTU, and E2) after single and multiple oral doses of TU dosage forms in the patients were recorded in connection with each daily dose listed in the report. Further analysis to identify a fixed dose dosing regimen that does not need titration for safety and efficacy was carried out based on the criteria targeted by US FDA. For example, the pharmacokinetic parameters of T level after administration of the dosing regimens for 225 mg BID-equal dose were measured and analyzed according to the criteria targeted by US FDA as
The overall analyzed results of this clinical study were plotted according to % of patients for safety (Cmax<1,500 ng/dL) and efficacy (Cavg>300 ng/dL) with a variety of dosing regimens. The results are shown in the table below. Note that only doses that were multiples of 75 mg were tested in the clinical study, the results predicted for the other doses are estimated from these values.
