Description
FIELD OF THE INVENTION

The present invention refers to a method for skin antiaging treatment comprising administering Botulinum toxin to an area of facial and/or neck skin, combined with the administration of a cosmetic or pharmaceutical composition comprising a cosmetically or pharmaceutically effective amount of at least one peptide derived from the SNAP-25 protein and/or at least one enkephalin-derived peptide, and at least one cosmetically or pharmaceutically acceptable excipient or adjuvant. The combined treatment prolongs in time the antiaging effectiveness of Botulinum toxin injections.


BACKGROUND OF THE INVENTION

Expression wrinkles are the wrinkles resulting from the stress exerted by the contractions of facial muscles responsible for causing facial expressions on the skin of the face. Expression wrinkles are usually located on the forehead, in the space between the eyebrows, around the mouth and/or around the eyes. Depending on the shape of the face, the expression frequency and the existence of tics (convulsive movements which are frequently repeated, caused by the involuntary contraction of one or several muscles, in this case facial muscles), expression wrinkles may even appear during adolescence. External factors such as exposure to the sun emphasize their depth and visibility.


The basis or mechanism for the formation of these facial wrinkles is the tensing of the muscles of the epidermis that drag the skin inwards. This muscular tension is the result of hyperactivity of the nerves innervating the facial muscles. Nerve hyperactivity is characterized by the uncontrolled and excessive release of, neurotransmitters that excite muscle fibers. Because of this, the molecules that control neuronal exocytosis contribute to relaxing muscular tension, and consequently, to eliminating wrinkles.


Botulinum toxin injections have been widely used for such purposes, in particular the A serotype (BOTOX® Cosmetic/Vistabel, Allergan Inc., Dysport™, Ipsen Biopharm, Ltd. and Azzalure®, Galderma S.A.) [Carruthers, A., Kiene, K. and Carruthers, J. (1996) “Botulinum A exotoxin use in clinical dermatology” J. Am. Acad. Dermatol. 34, 788-797; Cheng, C. M. (2007) “Cosmetic use of botulinum toxin type A in the elderly” Clin. Interv. Aging. 2, 81-83; Ascher, B, Talarico, S., Cassuto, D., Escobar, S., Hexsel, D., Jaén, P., Monheit, G., Rzany, B., Viel, M. (2010) “International consensus recommendations on the aesthetic usage of botulinum toxin type A (Speywood Unit)—part I: upper facial wrinkles” J. Eur. Acad. Dermatol. Venereol.]. Such techniques deliver toxin into muscles to produce a local effect. Botulinum neurotoxins inhibit the neuronal exocytosis in the neuromuscular junction (nerve-muscle synapse) by cleaving any of the proteins that make up the SNARE complex which directs and controls the release of acetylcholine accumulated in vesicles, thus causing weakness of the nearby muscle.


The paralytic effects of the toxin are reversible with an average duration of 3-4 months, depending on the severity of wrinkles and the strength of muscles treated [Rzany, B., Ascher, B., Monheit, G. D. (2010) “Treatment of glabellar lines with botulinum toxin type A (Speywood Unit): a clinical overview” J. Eur. Acad. Dermatol. Venereol. 24, S1, 1-14]. The maximum of efficacy after Botulinum toxin injection is obtained during the first month after the administration, with a sharp decay along the next couple of months, i.e. 2 months after Botulinum toxin injection the wrinkle reduction average is ca. 40% of the maximum of the wrinkle reduction average, and ca. 20% 4 months after the injection. The treatment therefore requires the repeated injection of Botulinum toxin, which may trigger an immune response which will end causing a clear loss of treatment efficacy. This loss of treatment efficacy with Botulinum toxin entails the need to increase the administered dose in subsequent treatments, which in turn causes a potentiation of the immune response. As an alternative to the treatment with Botulinum toxin serotype A, the use of different serotypes of Botulinum toxins, such as serotype B, serotype F and serotype E, has been considered. Nevertheless, the application of different serotypes cannot be considered a solution to the problem, because sooner or later, the immune reaction can occur again. Furthermore, the treatment with Botulinum toxins for aesthetic improvement is not exempt from adverse side effects, being the most frequently reported (custom-character0% prevalence) injection site reactions and headache, but also with a non negligible prevalence (custom-character10%) ptosis, facial paresis, lacrimation increase or dry eye, eyelid oedema, asthenopia and muscle twitching around eyes. Such side effects are transient and moderate in intensity but could last several weeks, and may discourage volunteers to reinject the toxin as soon as the wrinkles reappear. Botulinum toxin reinjection frequency must be consensuated with the physician who must balance between the benefit and the potential treatment-emergent side effects. As a regular medical praxis, physicians recommend reinjections every 6 months.


The cosmetic industry has made a lot of efforts to develop new molecules that imitate the paralytic effects of the Botulinum toxins, but with much simpler and more stable molecular structures, which do not induce immune responses, and whose manufacturing cost is economical. Peptide-type molecules comply with these properties and solve the problems presented by treatment with Botulinum toxin. Specifically, the patent EP 1180524 B1 and the patent application WO 2008/049945 A1 of Lipotec, S.A. describe peptides derived from the amino terminal fragment of the SNAP-25 protein which inhibit neuronal exocytosis and thus possess anti-wrinkle effect. The international application WO 97/34620 A1 also describes peptides derived from the amino acid sequence of the SNAP-25 protein, in particular its carboxy-terminal, or of synaptobrevin or syntaxin capable of inhibiting neuronal exocytosis.


A different approach for inhibiting muscle contraction is that achieved by acting at the post-synaptic level. This is the approach of some commercially available anti-expression wrinkle peptides such us Inyline™ [INCI: Acetyl Hexapeptide-30] marketed by Lipotec which interferes with the clustering of the acetylcholine receptor, or Vialox® [INCI: Pentapeptide-3] and Syn®-Ake [INCI: Dipeptide Diaminobutyroyl Benzylamide Diacetate], marketed by Pentapharm/DSM, which are antagonists of the acetylcholine receptor.


Other methods described for the reduction and/or elimination of expression wrinkles involve the use of calcium channel antagonists, particularly salts of manganese (FR 2809005 A1), alverine (FR 2798590 A1) or magnesium gluconate (FR 2846885 A1), or the use of chloride channel agonists such as glycine (EP 0704210 A2) or Iris pallida extracts (FR 2746641 A1).


A different mechanism of action for inhibiting neuronal exocytosis is described in the patent application EP 1892247 A1 of Lipotec, S.A. The document describes a family of peptides derived from the enkephalin sequence which are effective in the reduction and/or elimination of facial wrinkles, especially expression wrinkles, acting by activating K+ currents in neurons causing a hyperpolarizing effect which results in a reduction in Ca2+-dependent neuronal exocytosis.


In patent application EP 1892247 A1 of Lipotec, S.A. it is also described the effect of the combination of SNAP-25 derived peptides with enkephalin-derived peptides. The combination of both complementary mechanisms to attenuate muscle contraction provides an enhanced and sustained efficacy in reducing expression wrinkles.


There remains the need for improvement in performing Botulinum toxin treatments, and it is especially necessary to prolong the benefits received from the treatment and/or minimize the need for multiple treatments for a cosmetically or pharmaceutically noticeable outcome.


Surprisingly, the inventors have found that the administration in areas of facial and/or neck skin of a cosmetic or pharmaceutical composition comprising peptides derived from the SNAP-25 protein, which block neuronal exocytosis, and/or enkephalin-derived peptides, which reduce Ca2+-dependent neuronal exocytosis, prolong in time the antiaging effectiveness of Botulinum toxin injections.


DESCRIPTION OF THE INVENTION

This invention provides a solution to the above mentioned needs. This invention provides a method for skin antiaging treatment comprising administering Botulinum toxin to an area of facial and/or neck skin, combined with the administration of a cosmetic or pharmaceutical composition comprising a cosmetically or pharmaceutically effective amount of at least one peptide derived from the SNAP-25 protein, and/or at least one enkephalin-derived peptide, and at least one cosmetically or pharmaceutically acceptable excipient or adjuvant. The skin antiaging treatment is a treatment for reducing or eliminating wrinkles of the facial and/or neck skin.


This invention provides a simple, effective and risk-free solution for prolonging in time the temporary effects of the treatment with Botulinum toxin injections. The administration of a cosmetic or pharmaceutical composition containing peptides derived from the SNAP-25 protein and/or enkephalin-derived peptides maintains the benefit of the Botulinum toxin administration beyond the usual average of three-four months, and allows reducing the frequency of Botulinum toxin injections to two or less times per year. The anti-wrinkle effect of Botulinum toxin injections is better mantained until the next Botulinum toxin administration, and also the next Botulinum toxin administration can be delayed, reducing this way the probability of an immune response of the patient and loss of effectiveness of the treatment as a consequence of repeated administrations of Botulinum toxin. The treatment of this invention provides a wrinkle reduction average higher than 50% after 2 months in relation to the maximum of the wrinkle reduction average, higher than 25% after 4 months and higher than 10% after 6 months.


DEFINITIONS

In order to facilitate the comprehension of this invention, the meanings of some terms and expressions as they are used within the context of the invention are included.


Within the context of this invention the terms “aging” and “skin aging” are used to describe the emergence of visible changes in skin appearance as well as those perceptible by touch, such as for example and in a non-limiting sense wrinkles, fine lines, roughness, expression lines, stretch marks, discontinuities, furrows, flaccidity, skin sagging, such as cheeks sagging, eye pouches, double chin, increase of pore size, loss of elasticity, loss of resilience, loss of firmness, elastosis, anomalous differentiation, hyperkeratinization, keratosis, changes of the skin color, such as marks, redness or bags under the eyes, formation of hyperpigmented areas such as age spots, melasma or freckles, loss of smoothness, orange-peel skin, loss of collagen structure and other histological changes of the stratum corneum, of the dermis, epidermis, vascular system (for example the formation of spider veins or telangiectasias) or of those tissues close to the skin. Skin aging is a process with two main components: chronological, which is due to the passage of time, and photo-induced, which is due to the level of exposure to ultraviolet (UV) radiation and which is known as photoaging. The sum of several environmental factors such as exposure to tobacco smoke, exposure to pollution, and climatic conditions like cold and/or wind also contribute to skin aging.


Within the context of this invention, “skin antiaging treatment” is a treatment for preventing, delaying and/or reducing the aging of the skin in humans.

Peptides comprised in the cosmetic or pharmaceutical composition of the method of this invention may exist as stereoisomers or mixtures of stereoisomers; for example, the amino acids that make them up can have L-, D-configuration or be racemic independently from each other. Therefore, it is possible to obtain isomeric mixtures as well as racemates or diastereomeric mixtures or pure diastereomers or enantiomers, depending on the number of asymmetric carbons and what isomers or isomeric mixtures are present. The preferred structures of the peptides comprised in the cosmetic or pharmaceutical composition of the method of this invention are pure isomers, i.e., enantiomers or diastereomers. For example, unless otherwise indicated, it is understood that when it is indicated that one amino acid can be -Ala-, it is understood that it is selected from -L-Ala-, -D-Ala- or racemic or non-racemic mixtures of both. The methods described herein allow the person skilled in the art to obtain each of the stereoisomers of the peptide derivative of the invention by means of choosing the amino acid with the suitable configuration.

The “percentage of identity” refers to the percentage of amino acids that are identical between two compared amino acid sequences, after an optimal alignment of these sequences, where this percentage is purely statistical and differences between the two amino acid sequences are randomly distributed along the sequence. The term “optimal alignment” means the alignment of the amino acid sequences resulting in a higher percentage of identity. The percentage of identity is calculated by determining the number of identical positions where an amino acid is identical in the two sequences compared, dividing the number of identical positions by the number of positions compared and multiplying the result by 100 to get the percentage of identity between, the two sequences. Sequence comparisons between two amino acid sequences can be carried out manually or by software such as BLAST algorithm (Basic Local Alignment Search Tool), available online at the site http://blast.ncbi.nlm.nih.gov/.


In the context of this invention “enkephalin-derived peptides” means pentapeptides of general formula (II) with amino acid sequences that differ in 0, 1 or 2 amino acids from the amino acid sequences of the enkephalin pentapeptides defined by the sequences SEQ ID No.33 or SEQ ID No.34.

In Vivo Anti-Wrinkle Efficacy of Combined Treatment: Botulinum Toxin Type A and Composition Comprising Peptide Acetyl-SEQ ID No.11-NH2 and Peptide H-L-Tyr-D-Ala-L-Gly-L-Phe-L-Leu-OH (SEQ ID No.35)

A monocentric study was performed in double blind conditions to evaluate the anti-wrinkle effect of the compositions of Examples 2 and 3 after Botulinum toxin type A injection. Treatment with Botulinum toxin type A and composition of Example 1 (placebo) was used as the control treatment. Profilometric analysis of silicon replica imprints was performed to analyze wrinkle depth 2, 4 and 6 months (2M, 4M and 6M) after Botulinum toxin type A injection.


The study was done on 30 Caucasian females with an average age of 51, years old. All subjects received Botulinum toxin type A injections (Vistabel®, Allergan) in each periorbital region (crow's feet, 12.5 Units, U) and frontal region (25 U), receiving a total of 50 U of toxin.


After injections, a group of 8 volunteers initiated the application of the composition of Example 2, another group, of 9 volunteers received the composition of Example 3, and a final group of 13 volunteers received the placebo composition of Example 1. All volunteers applied the compositions of Examples 1, 2 or 3 twice a day.


Skin silicon replicas from the ocular periorbital region (crow's feet) and frontal region from 30 volunteers exposed to the treatments described before were obtained before Botulinum toxin type A injection (T0) and after 2, 4 and 6 months (2M, 4M and 6M) of the application of the placebo composition of Example 1 or the composition of Example 2 or Example 3. Briefly, on a clean Petri plate the silicon rubber material (Silflo®) was mixed with a catalyst in a ratio of about 3 drops of catalyst/2 ml paste. The two ingredients were mixed carefully together for 1 minute and were finally spread over the skin area in the periorbital and frontal regions, covering an area of 6×3 cm. After 12-15 minutes of drying, the silicone replica was peeled off from the skin.


The number of replicas per region obtained at each time point is indicated in Table 1:

Analysis of the study replicas was performed by confocal profilometry. A common area between replica obtained before treatment (T0 replica) and replicas at the different sampled times, from the same volunteer and study region (frontal or periorbital region) was selected for analysis. A confocal profilometer (PLμ, Industrial microscope Eclipse L150A, Nikon) mechanically scanned the replica surface by direct illumination and the reflected signal was observed with a CCD (Charged-Coupled Device) array and analyzed with different image data processing algorithm.


From each volunteer and each study region (frontal or periorbital), two independent previously selected areas (two wrinkles) were analyzed. The analyzed area was exactly the same area at all sampled times for the same study region and the same volunteer.


From the profilometric analysis of each macroroughness (or wrinkle) the profilometer software calculated the roughness parameters (Ra, Average surface roughness, the deviation from arithmetic mean of the evaluated relief; RMS, Root Mean Square roughness average of the evaluated relief; and PV, Peak-To-Valley distance, distance between the point of the maximum height and the point of the minimal height) values and processed the three-dimensional image. The Ra average is understood as the wrinkle reduction average when is related to wrinkle at T0. The Ra max is understood as the maximum of the wrinkle reduction average.
