SRGs in a cream formulation, CuradermBEC5, is very effective for the treatment of nonmelanoma skin cancers with excellent cosmetic end results. Intralesion injection of SRGs successfully dispose of very large tumours in animals without any clinical adverse effects. The mode of action of SRGs is by apoptosis. In this study, it is shown that small to large basal cell carcinomas are effectively treated only with topical application of CuradermBEC5. Here it is reported for the first time that combination of intralesion SRG injection and topical application with CuradermBEC5 in humans reduces the treatment time period by more than half when compared with topical application as the sole treatment regime. Two intralesion injections of very low doses of SRGs rapidly and effectively remove a large melanoma on a horse. If rapid removal of large troublesome skin cancers is required then this can be achieved by intralesion and topical treatments. Intralesion or combination therapy with SRGs may have some applications for melanomas in situ such as lentigo maligna.展开更多

The strengths and limitations of the established procedures are known. A new naturally derived topical cream, CuradermBEC5, for the treatment of non melanoma skin cancers has previously been described. In this communication, intra-comparison treatments of skin cancer between CuradermBEC5 therapy and the established treatments, surgery, radiation therapy, laser therapy, photodynamic therapy, imiquimod cream and cryosurgery are presented. Non melanoma skin cancer cases that had previously been treated unsuccessfully with the established procedures were subsequently treated successfully with CuradermBEC5. These observations are interesting because the identical lesions were treated by various modalities. In addition to the superior efficacious outcome of CuradermBEC5 therapy versus the established treatments, the cosmetic end results with CuradermBEC5 treatment are remarkable.展开更多

Basal cell carcinoma occurs when a mutation occurs in the DNA of a basal cell. The mutation inhibits apoptosis—the programmed cell death mechanism. The cell continues to multiply but does not die, resulting in a change in the skin, such as a growth or sore that will not heal. Basal cell carcinoma is the most common form of skin cancer and the most frequently occurring form of all cancers. Key words searched for the database of this communication were: Curaderm, BEC 5, cancer, skin cancer, basal cell carcinoma, nonmelanoma skin cancer, solamargine, solasonine and solasodine glycosides. <strong>Treatments:</strong> Several types of treatments are available to remove or destroy basal cell carcinoma. All currently used treatments are indiscriminate and also remove or destroy normal skin cells resulting in compromised cosmetic outcomes. <strong>Development of Curaderm Pharmacotherapy</strong>: Curaderm pharmacotherapy discriminates and specifically activates apoptosis at the molecular level in cancer cells but not in normal cells. Accordingly, Curaderm pharmacotherapy for basal cell carcinoma effectively and safely treats virtually all types, sizes and lesion locations. This review describes studies from the inception of Curaderm pharmacotherapy and covers the discovery of the anti-cancer effects, mode of action, preclinical, clinical and field applications with emphasis on efficacy, safety, compliance, tolerance, cost effectiveness and especially cosmetic outcome. In 2018 Curaderm was approved by the European Health Authorities as a Medical Device Class 1 for the indication “Topical Treatment with Keratolytic Action, and Antineoplastic Activity in the Treatment and Healing of Localized Basal Cell Carcinoma of the Skin”.展开更多

Non-melanoma skin cancers are often self-detected and are usually removed by various means in doctors’ surgeries. Mohs micrographic surgery is acclaimed to be the gold standard for the treatment of skin cancer. However, a novel microscopic molecular-cellular non-invasive topical therapy described in this article, challenges the status of Mohs procedure for being the acclaimed gold standard.展开更多

They are cytotoxic against multi-drug resistant tumor cells, stimulate lasting immunity against cancer, are not mutagenic and display anti-mutagenic properties. These antineoplastics, through cellular specific receptor-mediated actions, directly induce apoptosis by triggering extrinsic and intrinsic apoptotic pathways in cancer cells but not normal cells. CuradermBEC5 contains solasodine rhamnosides and is a topical formulation for the treatment of keratoses and non-melanoma skin cancers. The mode of action, together with the selectivity towards cancer cells, with CuradermBEC5 therapy, results in outstanding beneficial outcomes. This study shows graphically and pictorially that CuradermBEC5 seeks and destroys basal cell carcinoma whilst normal skin cells replace the dead cancer cells during therapy, emanating into impressive cosmetic end results. The clinical observations with CuradermBEC5 therapy reveal that initially the lesion size increases over four-fold due to the interaction of CuradermBEC5 with deeper and more lateral tumor cells, followed by a decrease in size, ultimately, resulting in complete elimination of the basal cell carcinoma.展开更多

Its incidence is higher than all other cancers combined. The developments of new treatments have not parallelled the increased incidences of this disease. A variety of treatments are available with differing outcomes.

Current guidelines provide no clear recommendations about preferred treatments. Methods The parameters;effectiveness, treatment duration, recurrence, side effects and cost of treatment were investigated for three frequently used topical therapies which were then compared with a most recent developed topical therapy. Published clinical data obtained from the literature was used to compare these parameters for 5-fluorouracil, imiquimod and diclofenac and relate them with the newly developed Curaderm. Results A wide variation in the concentrations of the active anti-keratotic ingredients, application frequency, duration of treatment, recurrence rates and cost of treatment exist between the different topical therapies. The efficacy rates and side effects were less variable. Overall, Curaderm is the most suitable treatment for actinic keratosis. Clinical evidence is presented illustrating the effects of Curaderm on field-directed treatments and solitary treatments of actinic keratoses. Conclusions Current medical guidelines do not provide clear recommendations on which treatment approach for actinic keratosis is preferred. Direct head-to-head comparison between treatments with emphasis on efficacy, safety, treatment duration, compliance, convenience, cosmetic outcome, patient acceptance and cost should be available to the patient, the practising physician, healthcare system and should assist in therapeutic treatment guidelines and policymaking. Given the very favourable profiles of these parameters with Curaderm when compared with other home-based treatments, it should be considered that Curaderm is first-in-line.展开更多

To assess dermal irritation, rabbits were dermally exposed to Curaderm for varying periods of time. To assess hypersensitivity, the guinea-pig maximisation test was applied. <strong>Results:</strong> Curaderm was only negligibly irritating using the criteria of erythema and oedema. Curaderm did not produce any sensitization toxicity of the skin. <strong>Conclusion:</strong> These studies confirm the non-toxic observations on normal skin experienced in the clinical setting when treating skin cancer and reinforce the specificity of Curaderm towards cancer cells.展开更多

Through basic and clinical research, non-invasive treatments like Curaderm have been developed, leading to improved quality of life for patients. Excipients, previously considered inactive ingredients, play a crucial role in enhancing the performance of topical formulations. The development of Curaderm emphasizes the importance of understanding the interactions between active ingredients, excipients, and the biological system to create effective and affordable pharmaceutical formulations. The systematic approach taken in the development of Curaderm, starting from the observation of the anticancer activity of natural solasodine glycosides and progressing through toxicological and efficacy studies in cell culture, animals, and humans, has provided insights into the pharmacokinetics and pharmacodynamics of solasodine glycosides. It is crucial to determine these pharmacological parameters within the skin’s biological system for maximal effectiveness and cost-effectiveness of a skin cancer treatment. Curaderm, as a topical treatment for nonmelanoma skin cancer, offers benefits beyond those obtained from other topical treatments, providing hope for improved quality of life for patients.展开更多

Conventional treatments to remove or destroy basal cell carcinoma are indiscriminate and also remove or destroy normal skin cells resulting in compromised cosmetic outcomes. Consequences of these treatments include body-image issues, anxiety, post-traumatic stress disorder, depression, and poorer quality of social and family life. A progressive topical cream formulation, Curaderm, containing the natural BEC glycoalkaloids, have shown to have advantages over conventional treatments. However, comprehensive clinical features of the skin cancer lesions during treatment with Curaderm have to date not been reported. This report shows that using unpublished data from a large number of patients with varying sizes, types and locations of basal cell carcinomas when treated with Curaderm in a phase 3 trial, an initial increase in size of the lesions occur, followed by a reverse course, leading to complete removal of the skin cancer. The specificity and mode of action of Curaderm explains the superior cosmetic outcomes when compared with conventional therapies.展开更多

High cure rates with BEC therapy have been obtained in animals with deadly cancers, and, in humans with terminal cancers promising results have been reported. At a clinical level, optimal concentrations of BEC have been established in a topical cream formulation Curaderm, for effective removal of skin cancers, but optimal concentrations of BEC have not been reported for other cancers. The objective of this study was to determine whether combination therapy of Cisplatin with BEC would result in synergism using cure rates as end points. BEC on its own cures Sarcoma 180 in mice, whereas, Cisplatin on its own has no effect on Sarcoma 180 activity. A combination of BEC and Cisplatin shows synergism, resulting in higher cure rates than BEC and Cisplatin at comparable individual concentrations.展开更多

Previous studies have described the efficacy of BEC on nonmelanoma skin cancers by topical application. Two cases are now reported which show that BEC in a cream formulation Curaderm is very effective for the treatment of large nonmelanoma skin cancers that are considered difficult to treat by existing modalities. Moreover, the cosmetic outcomes are very impressive.展开更多

Progresses have been made in the understanding of the molecular basis of cancer, cancer detection, and cancer treatment. Important strides by treating early-stage cancers have resulted in improved outcomes. Despite these achievements, mortality of cancer patients is high and still there is no cure. Some oncologists remain optimistic that cytotoxic chemotherapy will significantly improve cancer survival. However, notwithstanding the use of new and expensive single and more recently, combination drugs, the improvement of the response rates remains very low. In the United States, cancer death rates decreased by a mere 1.4% to 1.8% from 2004 to 2013. Compared to other serious diseases, the improvement of the cancer patient has been disappointingly lagging, and by far, most patients with advanced cancer eventually die of their disease. The need for improved cancer therapies is self-evident. This communication gives an overview of the overwhelming resurgence of solasodine and its glycosides in cancer therapy.展开更多
