Insights

New clinical trials show that combining apremilast with narrowband ultraviolet B therapy did not improve repigmentation in nonsegmental vitiligo patients. This highlights the challenges in treating this skin condition.

Area of Science:

  • Dermatology
  • Immunology
  • Pharmacology

Background:

  • Vitiligo treatment has lacked FDA-approved drugs for decades, despite recent advancements.
  • Targeted therapies show promise for repigmentation, but clinical trial results vary.
  • Managing vitiligo remains challenging, even with combined therapeutic approaches.

Purpose of the Study:

  • To evaluate the efficacy of combining apremilast (a phosphodiesterase 4 inhibitor) with narrowband ultraviolet B (NB-UVB) therapy.
  • To compare this combination therapy against a placebo plus NB-UVB in patients with nonsegmental vitiligo.

Main Methods:

  • A randomized clinical trial was conducted.
  • Participants received either apremilast plus NB-UVB or placebo plus NB-UVB.
  • Patient outcomes were assessed for repigmentation of vitiligo lesions.

Main Results:

  • The combination of apremilast and NB-UVB did not yield significantly better repigmentation results compared to placebo and NB-UVB.
  • The trial reported negative results, indicating no added benefit from apremilast in this context.
  • This underscores the complexity of achieving successful vitiligo treatment.

Conclusions:

  • Combining apremilast with NB-UVB is not an effective strategy for repigmenting nonsegmental vitiligo.
  • Further research is needed to understand the underlying mechanisms of vitiligo and develop effective treatments.
  • Negative trial results are crucial for advancing the understanding and management of vitiligo.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
