    EXAMPLES

    Example 1: Method of Manufacture

    [0275] The simplified generic manufacturing process of formulations in accordance with the present invention is as follows. Firstly, the colloidal dispersions comprising the deformable colloidal particles (for example, the Sequessome™ intermediate, Transfersome™ intermediate or Tethersome intermediate) are made. These colloidal dispersions are each formed from an ‘organic phase’ containing alcohol-soluble components and an ‘aqueous phase’ consisting of water-soluble components. Secondly, the gel phase (a thickener) is formed within which the colloidal dispersion(s) are dispersed. During this secondary stage, more than one kind of colloidal dispersion is introduced (each kind containing differing AOIs (or ‘extra’ ingredients) associated with the colloidal particles to give them unique characteristics), such that the final gelled product is then a blend of one or more individual kinds of vesicles (or colloidal particles). The AOIs or ‘extras’ may include zinc stearate, palmitoyl peptides, palmitoyl ascorbic acid (PAA), myristyl salicylate, tridecyl salicylate, vitamin D or vitamin E etc. (the ‘tethered’ ingredients). If desired, an AOI not associated with the colloidal particles can be added to the gel phase during secondary manufacture. If desired the first phase of the manufacturing process can be ordered so that the colloidal dispersions comprising the colloidal particles without any AOI are made in one or more formulations and then to each formulation an AOI (attached to a [phospho]lipid or a surfactant) is added. The second gel phase then occurs as above.

    Example 3

    [0280] An in-use study in healthy volunteers to investigate the anti-spot efficacy of two Example Formulations comprising chlorhexidine, using objective instrumental assessments of skin sebum levels and subjective visual assessments of lesion prevalence, against a placebo following a 3-week use period.

    [0281] The effectiveness of Formulation 4 and a second formulation (“Formulation 4.2”) was compared with a control product in their ability to control sebum and reduce the incidence of acne in acne-prone individuals.

    [0282] The Example Formulations (n=36 and n=37) contained empty Sequessomes™ and Tethersomes with tethered zinc and other excipients, including chlorhexidine as an anti-microbial preservative. The Sequessomes™ in the two Formulations contained different ratios of SPC:Tween (polysorbate) to assess if this affected the efficacy of the product. The control product contained no vesicles, zinc or chlorhexidine (n=20).

    [0283] Data Review

    [0284] The study assessed the efficacy and safety of treatment with Formulation 4 and Formulation 4.2 compared with placebo (control) in healthy volunteers with oily and spot-prone skin, confirmed by a clinical trials assistant prior to enrolment.

    [0285] Volunteers were either assessed at the centre on Day 3, 7, 14 and 21 or purely provided their own subjective assessments from home.

    [0286] In total, 224 volunteers completed the 3-week study: 37 were allocated to Formulation 4, 36 were allocated to Formulation 4.2 and 20 to placebo. Objective assessments included measurement of sebum on the face, Visia CR Photography (used to assess pore size and skin smoothness) and lesion counts (comedones, microcysts, papules and pustules). The subjective assessment was carried out using a subject Self Perception Questionnaire (SPQ).

    [0287] Sebum levels were reduced by over 20% from Baseline after 1 week of Formulation 4 and by more than 50% after 3 weeks' treatment (see FIG. 4). Published data demonstrate that a reduction in sebum production of 30-50% correlates with reduced acne symptoms..sup.1 The number of comedones (blocked pores) was also reduced with Formulation 4: by 50% from Baseline after 1 week and by more than 80% after 3 weeks (see FIG. 5). Notably, the number of pustules was reduced by 90% from Baseline after 1 week and they were virtually cleared after 3 weeks' treatment (see FIG. 6).

    [0288] These objective measurements were further validated by the subjective assessments. Additional subjects were given formulations to try and questionnaires to fill in, such that the sample size for each of the groups rose to 102 subjects, of which: [0289] 82% reported less painful spots [0290] 80% said they had less shiny skin [0291] 76% felt their blackheads reduced [0292] 75% reported less swollen spots [0293] 75% found they had no spot recurrence.

    [0294] Formulation 4 was well tolerated with no AEs reported and no erythema at the test site.

    [0295] This research demonstrates that Formulation 4 is a very effective treatment for acne. The reduction in sebum and both spots and blackheads at 21 days also support the role of Formulation 4 in preventing future recurrence of the symptoms.

    [0296] As mentioned, the objectively measured results demonstrated that against the control product the test products: [0297] Significantly reduced surface sebum (by up to 50%); [0298] Significantly reduced Comedones; [0299] Significantly reduced the numbers of papules and pustules.

    TABLE-US-00008 TABLE 4 summary of results Results of objective assessment Formulation 4.2 Formulation 4 Reduction in sebum after. . . 1 week >20%; 1 week >20%; 3 weeks >50% 3 weeks >50% Reduction in comedones after. . . 1 week >40%; 1 week = 50%; 3 weeks >90% 3 weeks >80% Reduction in pustules after. . . 1 week = 90%; 1 week >90%; 3 weeks >98% 3 weeks >98% Results of subjective assessment: % agreeing/strongly agreeing Product reduced blackheads 64.7% 76.5% Product stopped spots recurring 69.6% 74.5% Spots less painful (tender to touch) 66.7% 82.4% Spots not as swollen 73.5% 75.5% Skin less shiny 59.8% 80.4% Skin less oily 67.6% 77.5% Skin less greasy 69.6% 75.5%

    [0300] These results show the multifunctional nature of the formulation. It is believed that the colloidal particles in the formulations both assist in the clearing of the excess sebum from the skin surface, whilst their penetration into the skin drags the chlorhexidine in solution into the skin structure, killing bacteria. The tethered zinc may also have had a role in both reducing sebum production and/or having an anti-microbial function.

    Example 4: Anti-Ageing Trials. A Summary of Trials and Results

    SUMMARY

    [0349] Two trials of novel products have been undertaken to assess their efficacy and how they were perceived and received by users. See FIGS. 7, 8, 9 and 10.

    [0350] PROAWR1: A home-use study demonstrating the subjective and objective improvements in wrinkles and skin appearance after treatment with two different formulations of the same ingredients used with three different regimes

    [0351] PROAWR2: home-use study in three parallel groups of a preferred formulation and regime against a marketed comparator (in-market product A) and a control (placebo) product.

    [0352] The test formulas in the two trials were variants of the same ingredients, formulated by blending a mixture of Sequessome-based vesicles (i.e. colloidal particles), some of which had additional moieties tethered to the vesicle membrane.

    [0353] Headline Results

    [0354] PROAWR1: [0355] 100% of all participants on all three regimes had measured reduction in wrinkle volume after the first week [0356] The average scores both wrinkle volume reduction from baseline measurements and the reduction in appearance of wrinkles from baseline scores were highly significant (p<0.001) from week one [0357] There was mean reduction in actual wrinkle volume of 17.46% at week 12; the mean Glogau (appearance) score had reduced by 25.86% over the same period [0358] In the subjective assessments: [0359] 100% reported that their skin felt smoother and healthier and looked and felt plumper after 8 weeks [0360] Over 90% reported that their skin looked smoother and healthier, felt more elastic and that the bags and circles under their eyes had reduced [0361] 80.8% of participants claimed that after 8 weeks their skin looked younger by between 5 to 15 years; 50% claimed their skin looked younger by between 10 to 15 years.

    [0362] PROAWR2:

    [0363] For all three independently assessed metrics (actual wrinkle volume, the appearance of fine lines and wrinkles and the appearance of peri-orbital dark circles): [0364] Both the Test Formulation and the Commercial Product (in-market product A) were significantly better than the control in all three measures—no improvements were seen for the control group. [0365] The Test Formulation was equally effective as the in-market Commercial Product (in-market product A).

    [0366] PROAWR1: A home-use study demonstrating the subjective and objective improvements in wrinkles and skin appearance after treatment with a formulation in accordance with the present invention in healthy subjects with ageing and thinning skin

    SUMMARY

    [0367] This trial was conducted with two anti-ageing formulations in accordance with Example Formulation 1, “Dilute” and “Concentrated”. In the Concentrated version, the tethered ascorbate and tethered peptides were present at twice the concentration that they were in the Dilute version.

    [0368] The aim of this initial study was to examine the effectiveness of including these tethered moieties and whether the concentration of them in the formulations and the regime with which they were applied would affect their objective performance and the subjective perception of them by the participants.

    [0369] Three regimes were followed: [0370] Dilute: Applied twice a day all over the face and neck [0371] Concentrated:Applied once a day to targeted lines and wrinkles [0372] Combined: Participants on this regime used both products, as directed above

    [0373] The results showed that for the combined treatment: [0374] 100% of all participants on all three regimes had measured reduction in wrinkle volume after the first week. [0375] The average scores both wrinkle volume reduction from baseline measurements and the reduction in appearance of wrinkles from baseline scores were highly significant (p<0.001) from week one. [0376] There was mean reduction in actual wrinkle volume of 17.46% at week 12; the mean Glogau (appearance) score had reduced by 25.86% over the same period. [0377] In the subjective assessments: [0378] 100% reported that their skin felt smoother and healthier and looked and felt plumper after 8 weeks [0379] Over 90% reported that their skin looked smoother and healthier, felt more elastic and that the bags and circles under their eyes had reduced [0380] 80.8% of participants claimed that after 8 weeks their skin looked younger by between 5 to 15 years; 50% claimed their skin looked younger by between 10 to 15 years.

Duration of 12 week treatment period, with assessments at Baseline, Weeks 1, 2, 4, study: 6, 8 and 12. Study Started: w/c 11, Aug. 2014 Study Ended: w/e 21, Nov. 2014 Number of 79 subjects completed the study up to Week 8. 62 subjects completed subjects: the study including the 4 week extension to week 12. Method: Subjects underwent Profilometry assessments after which they were issued with an instruction sheet, diary cards and the test article on Week 0 (baseline). Subjects returned to the Test Centre on Weeks 1, 2, 4, 6 and 8 for Profilometry assessments. Visual assessments were performed on both ageing and peri-orbital dark circles at baseline and Weeks 1, 2, 4, 6 and 8. The subjects completed SPQ's at Week 4 and Week 8. DIC (Digital Image Capture) was performed on approximately 40% of subjects in each group at baseline, Week 2, 4 and 8). A 4 week extension was authorised for the study in which groups 1 and 2 were instructed to continue use of the product and undergo further profilometery and visual assessments at week 12. 50% of Group 3 were instructed to continue use of the regimen whilst the remaining 50% were instructed to use a bland moisturiser. Following week 12 assessments subjects were compensated for their time and inconvenience and exited from the study. Location: Princeton Consumer Research Ltd.

    SUMMARY

    [0389] This trial tested a preferred test anti-ageing formulation in accordance with the present invention (the “Concentrated” formulas from PROAWR1), against an in-market anti-ageing Commercial Product (in-market product A) and a control formulation.

    [0390] The aim of this study was to test: [0391] a) That previous results seen with the preferred formulation were real (control comparison) [0392] b) To assess the effectiveness against a currently marketed formulation for anti-ageing.

    [0393] The results showed that:

    [0394] For all three independently assessed metrics (actual wrinkle volume, the appearance of fine lines and wrinkles and the appearance of peri-orbital dark circles): [0395] Both the Test Formulation and the Commercial Product were significantly better than the control in all three measures—no improvements were seen for the control group. [0396] The Test Formulation was equally effective as the in-market Commercial Product.

    [0397] For the subjective assessment of the products: [0398] Both the Test Formulation and the Commercial Product were significantly better than the control in all measures [0399] The Test Formulation was rated higher than the Commercial Product for: [0400] Skin looked smoother [0401] Skin felt more plump [0402] Skin felt healthier [0403] Skin felt more elastic [0404] Complexion looked healthier [0405] Skin tone looked more even [0406] Eye puffiness reduction [0407] Effectiveness in anti-ageing [0408] Lifted sagging skin [0409] Hydration of skin [0410] Reducing pore size

When the subjects returned to the Test Centre on Week 8, they returned any unused test articles and their completed diary cards. Visual assessments were performed on both ageing and peri-orbital dark circles at baseline and Weeks 1, 2, 4, 6 and 8. The subjects completed SPQ's at Week 8. Professional photography was performed on approximately 40% of subjects in each group at baseline, and Weeks 1, 2, 4 and 8 with as many subjects as possible for group 1 being photographed above and beyond 40%. 70 subjects were also issued the product to use at home for the duration of the test period and completed an SPQ at the same time points as the active groups.

    Example 5: A Study in Volunteers to Investigate the Sensation Produced Using a Formulation Comprising Capsaicin

    BACKGROUND

    [0423] There are several products on the market that provide a warming sensation when applied to the joint or muscle, to relieve aches or pains. These products contain chemicals such as capsaicin which stimulate the nerve endings in the skin to create the warming sensations (without actually being related to a physical temperature change).

    [0424] The inventors have developed a capsaicin-containing formulation in accordance with the present invention, so that a warming sensation is associated with the product, either at application or sometime after. The formulation provides a combined effect of the joint-pain relieving property of drug-free colloidal dispersions, combined with a warming feeling.

    [0425] The formulation (TP2) comprised insoluble and inflexible liposomes comprising capsaicin and menthol in combination with Transfersomes™ comprising menthol.

    [0426] Transfersomes™/Sequessomes™/Tethersomes are flexible, deformable colloidal particles that make their own way into the skin, whereas liposomes are rigid vesicles that would not ordinarily be expected to penetrate the skin by themselves unless some other force is applied (e.g. Sequessomes™/Transfersomes™/Tethersomes in the same mixture opening pores and pulling/pushing the liposomes through).

    [0427] The starting material used to make TP2 is set out below.

    [0428] TP2 (PD-14-0073) was formed by taking 90 g of Start Material 1 and adding/mixing in 10 g of Start Material 2.

    [0432] Results

    [0433] The formulation was tried by three individuals. The results are presented in the table below.

    [0434] Conclusion/Summary

    [0435] These early results are useful in showing that: [0436] The warming sensation of capsaicin can be felt: [0437] In Transfersomes™—in the same “phase” as a joint-targeting colloidal particle [0438] In liposomes—separate “phase” to the joint-targeting colloidal particles
