Dainippon Sumitomo receives approval for Surepost, Repaglinide in combination with biguanides and thiazolidenediones
Repaglinide is an antidiabetic drug in the class of medications known as meglitinides, and was invented in 1983. It is sold by Novo Nordisk under the name of Prandin in theU.S., GlucoNorm in Canada, Surepost in Japan,Repaglinide in Egypt by EIPICO, andNovoNorm elsewhere. In Japan it is produced by Dainippon Sumitomo Pharma.
Repaglinide lowers blood glucose by stimulating the release of insulin from the pancreas. It achieves this by closing ATP-dependent potassium channels in the membrane of the beta cells. This depolarizes the beta cells, opening the cells’ calcium channels, and the resulting calcium influx induces insulin secretion.
Precursor drugs to repaglinide were invented in late 1983 by scientists at Dr Karl Thomae GmbH, a German drug manufacturer located at Biberach an der Riß in southern Germany which was acquired by Boehringer Ingelheim in 1990. The drug that became repaglinide was later licensed by Boehringer to Novo Nordisk, which filed an Investigational New Drugapplication for the compound with the Food and Drug Administration (FDA) in April 1992. Novo Nordisk filed its New Drug Application (NDA) for Prandin in July 1997 and it was quickly approved, gaining FDA approval in December 1997. The drug was the first of the meglitinide class. It was branded Prandin because its quick onset and short duration of action concentrates its effect around meal time (the prandium was the Roman meal which is comparable to the modern lunch).
After several attempts to file for U.S. patent protection, a filing was made in March 1990 which eventually became U.S. Patents 5,216,167 (June 1993), 5,312,924 (May 1994) and 6,143,769 (November 2000). After filing its NDA for repaglinide in 1997, Novo Nordisk applied for patent extension under the Hatch-Waxman Act. This process, called patent term restoration, allows drug patents to be extended based on the time that a drug spent in clinical trials and in the approval process. Previously it had been decided by the U.S. Patent and Trademark Office that the expiration date of U.S. Patents 5,216,167 and 5,312,924 would be 5 September 2006. In February 2001 Prandin’s patent life was extended to 14 March 2009 in response to Novo Nordisk’s patent term restoration application, with U.S. Patent 5,216,167 having been reissued as RE37035.[1]
Prior to the end of repaglinide’s patent term, Novo Nordisk obtained a new patent, U.S. Patent 6,677,358 (January 2004), covering the combination therapy of repaglinide together with the generic anti-diabetic drug metformin. This new patent was due to expire June 2018. In January 2011, a federal court ruled Novo Nordisk’s new patent invalid on the grounds of obviousness, and unenforceable on the grounds of inequitable conduct on the part of Novo Nordisk’s patent attorneys.[2]

KYTHERA Biopharmaceuticals, Inc. Announces Positive Interim Results from Open-Label Study of ATX-101 in the Reduction of Unwanted Submental Fat (SMF) or “Double Chin”
http://clinicaltrials.gov/ct2/show/NCT01426373
synthesis………..https://newdrugapprovals.org/2014/07/14/some-thing-for-your-chin-fda-accepts-kytheras-atx-101-new-drug-application/
The drug is sodium deoxycholate for injection, code-named ATX-101 was developed for the treatment of lipomas – benign tumors of subcutaneous adipose tissue, as well as other unwanted fatty growths, such as a double chin. This substance, which is a salt of one of the bile acids, emulsifies fats, destroying their excess deposits
ATX-101 (a first-in-class injectable drug being studied for the reduction of localized fat. ATX-101 is a proprietary formulation of deoxycholate a well-studied endogenous compound that is present in the body), a facial injectable drug for the reduction of unwanted fat under the chin, or submental fat. V. Leroy Young, MD, FACS, presented the initial results at the American Society for Aesthetic Plastic Surgery (ASAPS) 45th Annual Aesthetic Meeting in Vancouver, British Columbia, on May 4, 2012.
In August 2010 Bayer Consumer Care AG signed a licensing and development collaboration agreement with KYTHERA, thereby obtaining commercialization rights to ATX-101 outside the US and Canada. KYTHERA and Bayer are collaborating on the development of ATX-101 in Europe.
KYTHERA Biopharmaceuticals Inc. 02 MAR 3013, announced positive interim results from a Phase IIIb multi-center open-label study (ATX-101-11-26) to evaluate the safety and efficacy of ATX-101 an investigational injectable drug for the reduction of unwanted submental fat (SMF) commonly known as double chin. The results presented at the Late Breaking Research Symposium at the 71st American Academy of Dermatology (AAD) Annual Meeting in Miami Beach Fla. found that ATX-101 is well-tolerated and may be effective in reducing SMF by both clinician and patient reported outcome measures. The ATX-101 global clinical development program has enrolled more than 2500 total patients of which more than 1500 have been treated with ATX-101.
“In my practice patients often request a non-surgical way to treat their submental fat or undesirable double chin” said investigator Susan Weinkle MD FAAD a board certified dermatologist and affiliate clinical professor at the University of South Florida. “For these patients double chin is often resistant to diet and exercise. The results of this study suggest that microinjections of ATX-101 can reduce submental fat without worsening skin laxity.”
ATX-101 is a proprietary synthetically-derived formulation of deoxycholic acid (DCA) a naturally-occurring molecule found in the body that aids in fat metabolism. In this open-label Phase IIIb study interim results three months after the last ATX-101 treatment found:
- Reduction of submental fat
- 87 percent of patients achieved at least a one-grade improvement from baseline on the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)
- Similarly 83 percent of patients achieved at least a one-grade improvement on the Patient-Reported Submental Fat Rating Scale (PR-SMFRS)
- 96 percent of patients had unchanged or improved skin laxity based on the clinician rated Submental Skin Laxity Grading Scale (SMSLG)
- 95 percent of patients were satisfied with treatment based on the Global Post Treatment Satisfaction Scale
- Adverse events were of mild to moderate intensity transient and primarily associated with the treatment area
Topline results from this study were announced in November 2012. As previously announced 71.3 percent of subjects had at least a one-grade improvement on the CR-SMFRS / PR-SMFRS composite and 14.0 percent had at least a two-grade improvement on the same composite measure.
These results are based on a multicenter 12-month open-label Phase IIIb study conducted at 21 sites across the United States evaluating 165 adults who received injections of ATX-101 for up to six treatments at four-week intervals. Patients received ATX-101 (2 mg/cm2) by subcutaneous microinjections directly into their SMF and were evaluated three months after their last treatment. The study population includes females (77.6 percent) and males (22.4 percent) with a mean age of 47 who report at least moderate SMF and dissatisfaction with the appearance of their chin. All Fitzpatrick Skin Types an industry standard scale to categorize skin tone are represented.
“We are pleased with these ATX-101 study results” said Patricia S. Walker M.D. Ph.D. chief medical officer KYTHERA Biopharmaceuticals Inc. “These results along with efficacy analyses in double-blind placebo-controlled studies support ATX-101 entering the market as potentially the first medical aesthetic drug approved for the reduction of submental fat.”
About ATX-101
ATX-101 is a potential first-in-class injectable drug candidate under clinical investigation for the reduction of unwanted submental fat. ATX-101 is a proprietary formulation of synthetic deoxycholic acid a well-characterized endogenous compound that is present in the body to promote the natural breakdown of dietary fat. ATX-101 is designed to be a locally-injected drug that causes proximal preferential destruction of adipocytes or fat cells with minimal effect on surrounding tissue. Based on clinical trials conducted to date ATX-101 has exhibited significant meaningful and durable results in the reduction of submental fat which commonly presents as an undesirable “double chin.” These results correspond with subject satisfaction measures demonstrating meaningful improvement in perceived chin appearance.
In August 2010 Bayer signed a licensing and collaboration development agreement with KYTHERA thereby obtaining development and commercialization rights to ATX-101 outside of the U.S. and Canada. Bayer recently completed two pivotal Phase III trials of ATX-101 in Europe for the reduction of submental fat. Topline results from these trials were reported in the second quarter of 2012. KYTHERA completed enrollment in its pivotal Phase III clinical program for ATX-101 in more than 1000 subjects randomized to ATX-101 or placebo in 70 centers across the United States and Canada in August 2012. The Company expects to release topline results in mid-2013.

Celgene phase 3 – Oral Apremilast Achieves Statistical Significance for the Primary Endpoint of PASI-75 in the First Phase III Study in Patients with Psoriasis
APREMILAST, N-{2-[(1S)-1-(3-Ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl]-1,3-dioxo-2,3-dihydro-1H-isoindol-4-yl}acetamide
mar02,2013
Celgene International Sàrl, a subsidiary of Celgene Corporation (NASDAQ: CELG) today presented the results from ESTEEM 1, the Company’s first phase III study in psoriasis, at the American Academy of Dermatology annual meeting in Miami, Florida.
“I see this as a prime candidate for future management of psoriasis that allows us to treat a range of patients, including more moderate cases earlier on”
The company previously announced statistical significance for the primary and major secondary endpoint of PASI-75 at Week 16 and the Static Physician Global Assessment for patients receiving apremilast in the ESTEEM 1&2 phase III studies. ESTEEM 1&2 are the phase III registrational randomized, placebo-controlled studies evaluating the Company’s oral small-molecule inhibitor of phosphodiesterase-4 (PDE4) in patients with moderate-to-severe chronic plaque psoriasis.
ESTEEM 1, presented today, evaluated efficacy and safety in a range of patients. Approximately one-third of the study population was systemic and/or phototherapy treatment-naïve. Nearly 30 percent of the overall study population had prior biologic therapy, which included biologic-failures.
In the ESTEEM 1 study, a significantly higher percentage of apremilast-treated patients demonstrated PASI-75 at week 16 than did placebo patients (33.1% vs. 5.3%; P<0.0001). Significantly higher PASI-75 scores at week 16 were demonstrated across all patient segments enrolled in this study, including systemic-naïve and biologic-naïve patients receiving apremilast 30 mg BID compared with placebo (38.7% vs. 7.6%; P<0.0001 and 35.8% vs. 5.9%; P<0.0001 respectively). Apremilast demonstrated maintenance of effect over time, as measured by the Mean Percent Change from Baseline in PASI score over 32 weeks, with apremilast demonstrating a 54.9% reduction at week 16 and a 61.9% reduction at week 32.
Statistical significance at week 16 was also demonstrated in the major secondary endpoint, Static Physician Global Assessment (sPGA) of clear or almost clear (P<0.0001), and other key secondary endpoints (change in BSA, Pruritus VAS, DLQI), as well as in assessments of difficult to treat areas (nail and scalp psoriasis).
“I see this as a prime candidate for future management of psoriasis that allows us to treat a range of patients, including more moderate cases earlier on,” said Kristian Reich, M.D., SCIderm Research Institute and Dermatologikum Hamburg, Germany.
The overall safety and tolerability profile was consistent with results from previously reported phase III psoriatic arthritis trials. No cases of tuberculosis or lymphoma were observed through week 16, and there was no increased risk of cardiovascular events or serious opportunistic infection. Apremilast was generally well tolerated. The most common adverse events (AEs) greater than placebo were diarrhea, nausea and headache. Greater than 96% of patients in the study reported no AEs or mild to moderate AEs. A similar percentage of patients reported both serious AEs and severe AEs in the apremilast 30 mg BID treatment group compared to placebo (2.1% vs. 2.8% and 3.6% vs. 3.2%, respectively).
An NDA submission to the U.S. Food and Drug Administration, based on the combined ESTEEM 1&2 studies for psoriasis, is expected in the second half of 2013. The Company previously announced it expects to file a separate NDA for psoriatic arthritis in the first quarter of 2013. A combined PsA/psoriasis MAA submission in Europe is also planned for the second half of 2013.
Top-line positive results from the two pivotal, randomized, placebo-controlled phase III studies of apremilast in psoriasis (ESTEEM 1&2) were released in January 2013. The studies included more than 1,200 patients with moderate-to-severe psoriasis and are ongoing. Results from PSOR-005, a phase IIb dose-range study, were recently published in The Lancet (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60642-4/fulltext).
About ESTEEM 1 & 2
ESTEEM 1 & 2 are two pivotal phase III randomized, placebo-controlled studies evaluating apremilast in subjects with a diagnosis of moderate-to-severe chronic plaque psoriasis for at least 12 months prior to the screening, and at baseline, and who were also candidates for phototherapy and/or systemic therapy. Approximately 1,250 patients were randomized 2:1 to receive either apremilast 30 mg BID or placebo for the first 16 weeks, followed by a maintenance phase from weeks 16-32 in which placebo subjects were switched to apremilast 30 mg BID through week 32, and a randomized withdrawal phase for responders from Week 32-Week 52 based on their initial apremilast randomization and PASI response.
Apremilast, an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4), works intracellularly to modulate a network of pro-inflammatory and anti-inflammatory mediators. PDE4 is a cyclic adenosine monophosphate (cAMP)-specific PDE and the dominant PDE in inflammatory cells (see http://discoverpde4.com/). PDE4 inhibition elevates intracellular cAMP levels, which in turn down-regulates the inflammatory response by modulating the expression of TNF-α, IL-23, and other inflammatory cytokines. Elevation of cAMP also increases anti-inflammatory cytokines such as IL-10. To learn more go to www.discoverpde4.com/.
Top-line positive results from three pivotal randomized, placebo-controlled phase III studies of apremilast in PsA (PALACE 1, 2 & 3) were released in September 2012. PALACE 1 was also presented as an oral presentation at the ACR annual meeting in November 2012. Taken together, the PALACE program comprises the most comprehensive psoriatic arthritis studies to date intended for regulatory submission.
Results from PSA-001, the phase II study of apremilast in psoriatic arthritis, were recently published online in the journal Arthritis & Rheumatism (http://onlinelibrary.wiley.com/doi/10.1002/art.34627/abstract).
A randomized, placebo-controlled phase III study (POSTURE) of apremilast in ankylosing spondylitis (AS) began enrolling patients in April 2012. AS, a debilitating disease, which may cause fusion of the spine, arthritis, inflammation of the eye and damage to the heart, affects approximately 1.5 million people in the U.S. and Europe. The trial will randomize approximately 450 patients to receive 20 mg or 30 mg apremilast BID, or placebo BID.
Psoriasis is an immune-mediated, non-contagious chronic inflammatory skin disorder of unknown cause. The disorder is a chronic recurring condition that varies in severity from minor localized patches to complete body coverage. Plaque psoriasis is the most common type of psoriasis. About 80 percent of people who develop psoriasis have plaque psoriasis, which appears as patches of raised, reddish skin covered by silvery-white scales. These patches, or plaques, frequently form on the elbows, knees, lower back, and scalp. Psoriasis occurs nearly equally in males and females. Recent studies show that there may be an ethnic link. Psoriasis is believed to be most common in Caucasians and slightly less common in other ethnic groups. Worldwide, psoriasis is most common in Scandinavia and other parts of northern Europe. About 10 percent to 30 percent of patients with psoriasis also develop a condition called psoriatic arthritis, which causes pain, stiffness and swelling in and around the joints.

Apremilast is an orally available small molecule inhibitor of PDE4 being developed by Celgene for ankylosing spondylitis, psoriasis, and psoriatic arthritis.[1][2] The drug is currently in phase III trials for the three indications. Apremilast, an anti-inflammatory drug, specifically inhibits phosphodiesterase 4. In general the drug works on an intra-cellular basis to moderate proinflammatory and anti-inflammatory mediator production.
Apremilast is being tested for its efficacy in treating “psoriasis, psoriatic arthritis and other chronic inflammatory diseases such as ankylosing spondylitis, Behcet’s disease, and rheutmatoid arthritis.”

Taiho Pharma seeks Japanese nod to manufacture,market novel anti-tumour agent TAS-102
TRIFLURIDINE
TIPIRACIL
TAS-102 is an anti-cancer drug under development for colorectal cancer.[1]
| Combination of | |
|---|---|
| Trifluridine | cytotoxin |
| Tipiracil | thymidine phosphorylase inhibitor |
Clinical trials
A phase II trial reported in 2011[2] and a phase III trial is due to end in 2014.[1][3]
Mechanism
TAS-102 consists of the cytotoxin trifluridine and the thymidine phosphorylase inhibitor (TPI) tipiracil.[4] Trifluridine is incorporated into DNA during DNA synthesis and inhibits tumor cell growth. Tipiracil protects trifluridine from being broken down when taken orally.

Taiho Pharmaceutical Co., Ltd. has submitted an application to the Japanese Ministry of Health, Labour and Welfare for approval of the manufacture and marketing of the novel oral nucleoside anti-tumour agent TAS-102 (combination of trifluorothymidine [FTD] and tipiracil hydrochloride [TPI]). Taiho is seeking approval of TAS-102 for the indication of unresectable, advanced, recurrent colorectal cancer. The application for approval is based on the results of a phase II clinical trial (Study 10040030) conducted at 20 facilities throughout Japan. It was a randomized, double-blind comparative study of TAS-102 and a placebo involving 172 patients with unresectable, advanced, recurrent colorectal cancer that was refractory to the standard chemotherapy of at least two or more regimens containing fluoropyrimidine, irinotecan, and oxaliplatin. The results indicated that the group administered TAS-102 had improved overall survival rates (median overall survival: 9.0 months vs. 6.6 months) and a significantly reduced risk of mortality (HR: 0.56, p=0.0011). The most frequently reported adverse drug reaction with a CTCAE grade of 3 or higher was neutropenia. Grade 3 or higher diarrhea, fatigue, nausea, and other adverse reactions were no more than 10 per cent. Taiho Pharmaceutical is currently proceeding with a global phase III clinical trial of TAS-102 in a similar colorectal cancer population (RECOURSE) with the ultimate goal of global registration and commercialization of the agent. Taiho Pharmaceutical believes that TAS-102 will make a significant contribution to cancer patients and will continue its development efforts to broaden its use. TAS-102 is an anti-tumour agent composed of a combination of trifluorothymidine (FTD), a nucleoside that incorporates into DNA and inhibits a variety of genetic functions required for the proliferation of cancer cells, and tipiracil hydrochloride (TPI), an inhibitor of thymidine phosphorylase (which degrades FTD) that maintains an effective blood concentration of FTD. TAS-102 is administered twice daily to achieve a total daily dose of 70mg/m2 for five days followed by two days of rest and then repeated a second time. This is followed by a 14-day rest period to make a 28-day schedule for one course. |

Novartis’ Ilaris canakizumab has become the first biologic drug to be approved in the EU to treat the symptoms of gouty arthritis

Novartis’ Ilaris has become the first biologic drug to be approved in the EU to treat the symptoms of gouty arthritis in another gain for the interleukin-1 beta inhibitor.
march01,2013
First biologic drug approved for condition in Europe
The European Commission (EC) cleared llaris (canakizumab) for the treatment of adult patients who have suffered at least three gouty arthritis attacks in the previous 12 months, but who are unsuitable for treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine or repeated courses of corticosteroids.
Gouty arthritis – commonly known as gout – is an “excruciating condition”, according to Novartis division head David Epstein, who noted that Ilaris offers new hope to patients who do not currently have treatment options.
Data from two phase III trials of Ilaris in acute gouty arthritis attacks showed that patients treated with the drug experienced significantly greater pain relief compared to the injectable steroid triamcinolone acetonide, while most adverse events were mild to moderate in severity.
The most frequent side effects were infections, and particularly upper respiratory tract infections and nasopharyngitis.
Ilaris was launched in the US and EU in 2009 as a treatment for an auto-inflammatory condition called cryopyrin-associated periodic syndrome (CAPS). The rarity of that condition has meant sales have been relatively small, coming in at $72m last year, albeit a 56 per cent gain over 2011.
Gouty arthritis is a much bigger market for the drug and, along with a juvenile arthritis indication Novartis is pursuing, could push Ilaris towards blockbuster status with sales in excess of $1bn a year.
“Our vision is to realise the potential of Ilaris wherever IL-1 beta plays a key role and available treatment options don’t give patients the help they need,” said Epstein.
EU approval comes after the US FDA knocked back Ilaris for gouty arthritis, saying in 2011 that Novartis needed to provide more data on the drug’s risk-benefit profile, specifically its potential to leave patients vulnerable to infections.
Gout has been a tricky indication for drug developers to crack, with the FDA turning down another CAPS treatment – Regeneron’s IL-1 inhibitor Arcalyst (rilonacept) – in 2012 on the grounds of inadequate safety data and concern about a risk of malignancy.
One success came in 2010 when Savient secured approval for its Krystexxa (pegloticase) drug as a second-line treatment after oral xanthine oxidase inhibitors in patients with severe debilitating chronic tophaceous gout.
However, the drug has failed to make significant inroads because of a high price and tendency to stimulate neutralising antibodies that limit its therapeutic effect, according to Decision Resources.
There is still a great demand for safer and more effective therapies with the phase III pipeline featuring another potential blockbuster in the form of AstraZeneca/Ardea Biosciences URAT1 inhibitor lesinurad.
Canakinumab (INN, trade name Ilaris, previously ACZ885)[1] is a human monoclonal antibody targeted at interleukin-1 beta. It has no cross-reactivity with other members of the interleukin-1 family, including interleukin-1 alpha.[2]
Canakinumab was approved for the treatment of cryopyrin-associated periodic syndromes (CAPS) by the US FDA on June 2009[3] and by the European Medicines Agency in October 2009.[4] CAPS is a spectrum of autoinflammatory syndromes including familial cold autoinflammatory syndrome, Muckle–Wells syndrome, and neonatal-onset multisystem inflammatory disease.
Canakinumab was being developed by Novartis for the treatment of rheumatoid arthritis but this trial has been discontinued.[5] Canakinumab is also in phase I clinical trials as a possible treatment for chronic obstructive pulmonary disease.[6]

aripiprazole
mar 1, 2013
Otsuka Pharmaceutical Co., Ltd. (Otsuka) and H. Lundbeck A/S (Lundbeck) announced the U.S. Food and Drug Administration (FDA) has approved ABILIFY MAINTENA™ (aripiprazole) for extended- release injectable suspension, an intramuscular (IM) depot formulation indicated for the treatment of schizophrenia.
ABILIFY MAINTENA is the first dopamine D2 partial agonist approved as a once- monthly injection. It contributes a new treatment option to address the ongoing need for relapse prevention in patients with schizophrenia – a chronic, debilitating disease.
Efficacy was demonstrated in a 52-week, placebo-controlled, double-blind, randomized-withdrawal, Phase 3 maintenance trial of ABILIFY MAINTENA in patients with schizophrenia. The time to relapse was the primary endpoint. In the trial, ABILIFY MAINTENA>1 In a key secondary endpoint, the percentage of subjects experiencing relapse (i.e., meeting clinical trial criteria for exacerbation of psychotic symptoms/relapse) was also significantly lower with ABILIFY MAINTENA compared to placebo at the end of the study (10% vs. 40%, respectively; p<0.0001). Additional support for efficacy was derived from oral aripiprazole trials.
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. ABILIFY MAINTENA is not approved for the treatment of patients with dementia-related psychosis. ABILIFY MAINTENA is contraindicated in patients with a known hypersensitivity reaction to aripiprazole. Reactions have ranged from pruritus/urticaria to anaphylaxis (see Important Safety Information below).

EU OKs Lundbeck’s Selincro, Nalmefene to cut alcoholic urges
Nalmefene
17-cyclopropylmethyl-4,5α-epoxy-6-methylenemorphinan-3,14-diol
march 1 2013
Lundbeck will be celebrating news that European regulators have issued a green light for Selincro, making it the first therapy approved for the reduction of alcohol consumption in dependent adults.
Selincro (nalmefene) is a unique dual-acting opioid system modulator that acts on the brain’s motivational system, which is dysregulated in patients with alcohol dependence.
The once daily pill has been developed to be taken on days when an alcoholic feels at greater risk of having a drink, in a strategy that aims to reduce – rather than stop – alcohol consumption, which some experts believe is a more realistic goal.
Clinical trials of the drug have shown that it can reduce alcohol consumption by approximately 60% after six months treatment, equating to an average reduction of nearly one bottle of wine per day.
In March last year, data was published from two Phase III trials, ESENSE 1 and ESENSE 2, showing that the mean number of heavy drinking days decreased from 19 to 7 days/month and 20 to 7 days/month, while TAC fell from 85 to 43g/day and from 93 to 30g/day at month six. However, the placebo effect was also strong in the studies.
According to Anders Gersel Pedersen, Executive Vice President and Head of Research & Development at Lundbeck, Selincro “represents the first major innovation in the treatment of alcohol dependence in many years,” and he added that its approval “is exciting news for the many patients with alcohol dependence who otherwise may not seek treatment”.
Alcohol dependence is considered a major public health concern, and yet it is both underdiagnosed and undertreated, highlighting the urgent need for better management of the condition.
In Europe, more than 90% of the 14 million patients with alcohol dependence are not receiving treatment, but research suggests that treating just 40% of these would save 11,700 lives each year.
The Danish firm said it expects to launch Selincro in its first markets in mid-2013, and that it will provide the drug as part of “a new treatment concept that includes continuous psychosocial support focused on the reduction of alcohol consumption and treatment adherence”.
Nalmefene (Revex), originally known as nalmetrene, is an opioid receptor antagonistdeveloped in the early 1970s, and used primarily in the management of alcoholdependence, and also has been investigated for the treatment of other addictions such aspathological gambling and addiction to shopping.
Nalmefene is an opiate derivative similar in both structure and activity to the opiate antagonist naltrexone. Advantages of nalmefene relative to naltrexone include longer half-life, greater oral bioavailability and no observed dose-dependent liver toxicity. As with other drugs of this type, nalmefene can precipitate acute withdrawal symptoms in patients who are dependent on opioid drugs, or more rarely when used post-operatively to counteract the effects of strong opioids used in surgery.
Nalmefene differs from naltrexone by substitution of the ketone group at the 6-position of naltrexone with a methylene group (CH2), which considerably increases binding affinity to the μ-opioid receptor. Nalmefene also has high affinity for the other opioid receptors, and is known as a “universal antagonist” for its ability to block all three.

About Amicus Therapeutics
Amicus Therapeutics is a biopharmaceutical company at the forefront of therapies for rare and orphan diseases. The Company is developing orally-administered, small molecule drugs called pharmacological chaperones, a novel, first-in-class approach to treating a broad range of human genetic diseases. Amicus’ late-stage programs for lysosomal storage disorders include migalastat HCl monotherapy in Phase 3 for Fabry disease; migalastat HCl co-administered with enzyme replacement therapy (ERT) in Phase 2 for Fabry disease; and AT2220 co-administered with ERT in Phase 2 for Pompe disease.
About Migalastat HCl
Amicus in collaboration with GlaxoSmithKline (GSK) is developing the investigational pharmacological chaperone migalastat HCl for the treatment of Fabry disease. Amicus has commercial rights to all Fabry products in the United States and GSK has commercial rights to all of these products in the rest of world.
As a monotherapy, migalastat HCl is designed to bind to and stabilize, or “chaperone” a patient’s own alpha-galactosidase A (alpha-Gal A) enzyme in patients with genetic mutations that are amenable to this chaperone in a cell-based assay. Migalastat HCl monotherapy is in Phase 3 development (Study 011 and Study 012) for Fabry patients with genetic mutations that are amenable to this chaperone monotherapy in a cell-based assay. Study 011 is a placebo-controlled study intended primarily to support U.S. registration, and Study 012 compares migalastat HCl to ERT to primarily support global registration.
For patients currently receiving ERT for Fabry disease, migalastat HCl in combination with ERT may improve ERT outcomes by keeping the infused alpha-Gal A enzyme in its properly folded and active form thereby allowing more active enzyme to reach tissues.2 Migalastat HCl co-administered with ERT is in Phase 2 (Study 013) and migalastat HCl co-formulated with JCR Pharmaceutical Co. Ltd’s proprietary investigational ERT (JR-051, recombinant human alpha-Gal A enzyme) is in preclinical development.
About Fabry Disease
Fabry disease is an inherited lysosomal storage disorder caused by deficiency of an enzyme called alpha-galactosidase A (alpha-Gal A). The role of alpha-Gal A within the body is to break down specific lipids in lysosomes, including globotriaosylceramide (GL-3, also known as Gb3). Lipids that can be degraded by the action of α-Gal are called “substrates” of the enzyme. Reduced or absent levels of alpha-Gal A activity leads to the accumulation of GL-3 in the affected tissues, including the kidneys, heart, central nervous system, and skin. This accumulation of GL-3 is believed to cause the various symptoms of Fabry disease, including pain, kidney failure, and increased risk of heart attack and stroke.
It is currently estimated that Fabry disease affects approximately 5,000 to 10,000 people worldwide. However, several literature reports suggest that Fabry disease may be significantly under diagnosed, and the prevalence of the disease may be much higher.

Vertex Pharmaceuticals announced Tuesday night the design of two phase III studies for its combination therapy to treat the most common form of cystic fibrosis. The studies will each run for six months, so results could be ready as early as the end of 2013 or during first half of 2014.
The studies announced Tuesday will evaluate the two different doses of an experimental medicine VX-809 in combination with Kalydeco. Each study will enroll 500 cystic fibrosis patients randomized to either the VX-809/Kalydeco arms or a placebo for six months of treatment. The studies’ primary endpoint will be the relative improvement in lung function of VX-809/Kalydeco compared to placebo.
Last fall, Vertex presented data from a phase II study demonstrating that a 600 mg dose of VX-809 and Kalydeco worked synergistically to improve lung function in cystic fibrosis patients with the F508del mutation compared to placebo. This same dose combination will be tested in the phase III study along with a higher 800 mg (actually, 400 mg given twice a day) dose of VX-809 plus Kalydeco.
Vertex also announced new data from this phase II study on Tuesday night showing similar lung function improvements between the 800 mg and 600 mg doses of VX-809. For this reason, the higher dose was included in the phase III studies.
Along with the two phase III studies in adult patients, Vertex will also conduct a six-month study of the combination therapy in pediatric patients ages 6 to 11. This study, along with the data from the adult studies, may be used to expand the combination therapy’s approval into younger patients.
In January, FDA anointed Kalydeco and VX-809 with Breakthrough Therapy Designation as part of the agency’s efforts to accelerate the development and approval of drugs for serious and life-threatening disease. Vertex did not say whether Breakthrough Designation played a specific role in the VX-809/Kalydeco phase III program but the relatively short six-month duration of the studies plus the ability to test the combination in children at the same time does accelerate the development of the combination therapy. If the data from the studies are positive, the drugs could be approved sooner than expected and for more patients.
Lumacaftor (USAN, codenamed VX-809) is an experimental drug for the treatment of cystic fibrosis, being developed by Vertex Pharmaceuticals. The drug is designed to be effective in patients that have the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR), the defective protein that causes the disease. F508del, meaning that the amino acid phenylalanine in position 508 is missing, is found in about 60% of cystic fibrosis patients.[1]
Interim results from a Phase II clinical trial indicate that patients with the most common form of genetic mutation causing cystic fibrosis homozygous F508del had an 8.5% increase in lung function (FEV1) after 56 days on a combination of lumacaftor and ivacaftor (Kalydeco).[2]
