MAA: a moment in Clinuvel’s EPP story

Thursday, February 9th, 2012

Those who have taken an interest in Clinuvel will have learned with joy that, on Monday February 6th, the company announced its first official filing for SCENESSE® (afamelanotide) with the European Medicines Agency. It has taken our teams around six years to arrive at this point. Benchmarked against peer companies, it is a relatively swift development path for a first-in-class drug; we first publicly announced our erythropoietic protoporphyria (EPP) program in September 2006. It is an opportune moment to reflect briefly on how we reached this milestone and then discuss the steps that must be taken from here. (more…)

EPP results and clinical relevance

A protoporphyrin IX molecule

Over recent months I have written several times of the need for Clinuvel to prove clinical relevance in our trials with the use of SCENESSE® (afamelanotide) in erythropoietic protoporphyria (EPP). In orphan populations the need to demonstrate how a novel drug assists in their daily activities and improve their lives is at the forefront of the regulators’ minds. And so it should be, after all the objective of the pharmaceutical industry is to develop drugs which address either disease or symptoms adequately and safely. The results the company released yesterday from our Phase II US study of the drug in EPP (CUV030) have given us important data towards demonstrating clinically relevant improvement of patients’ lives.

The importance of clinical relevance

Tuesday, August 2nd, 2011

Development of novel drugs is truly like no other business: one attempts to address questions that may have never been previously posed – let alone answered – in the pursuit of improving the lives and quality of life of patients. As I eluded to in my recent letter to shareholders, the team is now well into the analysis of results from our erythropoietic protoporphyria (EPP) program; two studies from the US and Europe. This is a complex and time consuming task that requires one to collate and make sense of thousands of data points to answer a seemingly straight forward question: does this trial show that the drug is safe and effective?

Obtaining an answer needs to be understood from the concept of clinical relevance. Put simply, results don’t just need to show that a treatment or intervention has an effect on a disease. Rather, they need to indicate that that effect is relevant to the current clinical understanding, treatment and care for the disease or indication. They need to show that the drug’s effect is having a positive, meaningful impact upon a patient’s prognosis and care. This is a crucial point to consider in the development of protocols and in the careful analysis of results, as it is how regulators will review the results. (more…)

Afamelanotide: an analogue of α-MSH designed to assist in vitiligo repigmentation

Monday, July 25th, 2011

Vitiligo is a common skin depigmentation disorder in which the melanocytes, the skin cells which produce melanin pigment, are progressively lost. Despite this, melanocyte stem cells, or immature melanocytes, are preserved in a special region within hair follicles called the bulge, or niche. Often these cells are able to be stimulated with narrowband ultraviolet B (NB-UVB) phototherapy to mature into fully functional melanocytes which migrate to the epidermis to replace the lost or damaged cells. Upon further exposure to UVB radiation, skin cells (keratinocytes) manufacture a hormone called alpha-melanocyte-stimulating hormone, or α-MSH. Alpha-MSH binds to receptors on the newly formed melanocytes and activates melanin production to repigment areas of skin affected by vitiligo. (more…)

‘Measuring’ vitiligo: the challenges of clinical and treatment evaluation

Monday, April 4th, 2011

Since our announcement last year that Clinuvel would commence a new program for SCENESSE® (afamelanotide) in nonsegmental vitiligo, the company has received vast interest in the application of the drug in this disease. Of the enquiries that best captured the essence of this program, one stood out: a US based analyst asked how the company intended to objectively measure the response to treatment, the repigmentation of vitiliginous lesions, in its trial.

A clinical success: study retention rates

Thursday, February 10th, 2011

We were delighted this week to be able to announce the successful completion of our first Phase II study conducted in the US, a placebo controlled, randomised trial of SCENESSE® (afamelanotide) for patients diagnosed with erythropoietic protoporphyria (EPP) (CUV030). (more…)

Compassionate use – navigating the regulatory landscape to ‘do good’

Friday, December 3rd, 2010

As snow begins to fall around Clinuvel’s European office, the team in Australia is preparing for a long hot summer. The seasons are at the forefront of our minds at Clinuvel, since our lead drug SCENESSE® appears to have a dramatic impact on the ability of patients to expose themselves to sun. We try to test the drug under the most extreme conditions, meaning trials must be conducted in spring and summer. As the seasons change, we begin to see more requests and enquiries from the southern hemisphere, in particular from patients with erythropoietic protoporphyria (EPP), seeking access to the drug outside of formal trial programs.
