NDA FDA-Nuvo reports FDA response to PENNSAID 2% , diclofenac sodium topical solution, 2% w/w

DICLOFENAC

PENNSAID 2%
7 MAR 2013
The US Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) to Nuvo Research’s US licensing partner, Mallinckrodt, following the review of Mallinckrodt’s New Drug Application (NDA) for diclofenac sodium topical solution, 2% w/w (PENNSAID 2%).
FDA in the letter mentioned that it requires Mallinckrodt’s complete pharmacokinetic study comparing PENNSAID 2% to original PENNSAID 1.5%.
FDA denied to review the similar pharmacokinetic studies submitted by Mallinckrodt with the NDA, as the reserve samples were not retained at the clinical site.
Pharmacokinetic studies are standard studies conducted during a drug development program to identify the total exposure or the amount of drug that reaches the blood stream after a patient receives both single and multiple doses of the product.
Mallinckrodt has suggested Nuvo that it expects to complete the study and submit the results to the FDA in the third quarter of 2013, and that it anticipates the FDA will provide a formal response to the filing within 6 months thereafter.
Nuvo’s Pain Group president Dr. Bradley Galer said with the new FDA’s letter the firm was disappointed that PENNSAID 2% will not be approved in this review cycle.
“We are pleased that the FDA has outlined a clear pathway to approval that we believe can be completed in a relatively short time frame,” Galer added.
“Upon approval, PENNSAID 2% will be the first and only topical NSAID in the U.S. featuring twice per day dosing and a metered dose pump bottle.”
Takeda Submits Marketing Authorisation Application for Vedolizumab in Moderately to Severely Active Ulcerative Colitis and Crohn’s Disease in the European Union

March 7, 2013
Pharmaceutical Company Limited (“Takeda”) today announced that a Marketing Authorisation Application (MAA) has been submitted to The European Medicines Agency (EMA) for vedolizumab, an investigational, gut-selective humanized monoclonal antibody for the treatment of adults with moderately to severely active ulcerative colitis (UC) and Crohn’s disease (CD), the two most common types of inflammatory bowel disease (IBD). If approved, vedolizumab would be the first and only gut-selective biologic agent for UC and CD on the market.
“Ulcerative colitis and Crohn’s disease are chronic debilitating diseases with important unmet medical needs, often affecting young people in the prime of their lives,” said Asit Parikh, M.D., Ph.D., vice president, general medicine, Takeda. “We are encouraged by the findings of GEMINI, the vedolizumab Phase 3 clinical development program, which studied approximately 3,000 patients in nearly 40 countries, making it the largest IBD clinical trial program conducted to date.”
Nearly four million people worldwide are affected by IBD, with UC affecting more than 500,000 people and CD affecting approximately 230,000 people in the EU. Crohn’s disease and ulcerative colitis are chronic diseases that cause inflammation of the lining of the digestive tract. Inflammation caused by CD can involve varying areas of the digestive tract, while UC impacts the colon only. CD and UC can be both painful and debilitating, which may sometimes lead to serious complications and can significantly impact the quality of life for patients.
The MAA submission was supported by Phase 3 clinical studies, GEMINI I, GEMINI II, GEMINI III and GEMINI LTS (Long-term Safety), which are part of the GEMINI Studies™, a four-study clinical research program to investigate the efficacy and safety of vedolizumab on clinical response and remission in moderately to severely active CD and UC patients, who had failed at least one conventional or anti-TNFα therapy.
“With a targeted mechanism of action, vedolizumab has clinical promise as a potential treatment option for people with moderate to severely active CD and UC,” said Paul Rutgeerts, M.D., Ph.D., F.R.C.P., professor of medicine, Catholic University of Leuven, Belgium. “While there is no known cure, there is a need for new CD and UC treatment options, in an effort to provide patients with additional choices for managing their disease, reducing symptoms and achieving remission.”
About Crohn’s disease and ulcerative colitis
Crohn’s disease (CD) and ulcerative colitis (UC) are the two most common forms of inflammatory bowel disease (IBD), which is marked by inflammation in the lining of the GI tract. CD can impact any part of the digestive tract, and common symptoms may include abdominal pain, diarrhea, rectal bleeding, weight loss, and/or fever. UC impacts the large intestine only, which includes the colon and the rectum. The most common symptoms of UC include abdominal discomfort and blood or pus in diarrhea. There is no known cause for CD or UC, although many researchers believe that the interaction of an outside agent, such as a virus or bacteria, with the body’s immune system may trigger them. No cure exists for CD or UC; the aim of IBD treatments is to induce and maintain remission, or achieve extended periods of time when patients do not experience symptoms.
About vedolizumab
Vedolizumab was developed for the treatment of CD and UC, as a gut-selective, humanized monoclonal antibody that specifically antagonizes the alpha4beta7 (α4β7) integrin, which is expressed on a subset of circulating white blood cells. These cells have been shown to play a role in mediating the inflammatory process in CD and UC. α4β7 binds with a specific adhesion molecule primarily expressed in the intestinal tract. Therefore, vedolizumab, by preventing this interaction, has a gut selective effect.

Vedolizumab is a monoclonal antibody being developed by Millennium Pharmaceuticals, Inc. for the treatment of ulcerative colitis and Crohn’s disease.It binds to integrin α4β7(LPAM-1, lymphocyte Peyer’s patch adhesion molecule 1).[1][2]
The molecule was first identified by Dr. Andrew Lazarovits [1][2] as the murine MLN0002 homologue. His discovery of the mouse equivalent of this antibody—originally applied to anti-rejection strategies in kidney transplantation—was published in the journal Nature in 1996. The drug was then licensed to Millennium Pharmaceuticals of Boston for further development.
As of October 2009, vedolizumab is undergoing Phase III trials.[3] Clinical trials indicate that Vedolizumab was found safe and highly effective for inducing and maintaining clinical remission in patients with moderate to severe ulcerative colitis [3]. Dr. Brian Faegan, head researcher, reported an absence of any instances of progressive multifocal leukoencephalopathy (PML), which is a particularly important finding [4]. It looks like it will be an effective abiologic agent without some of the toxicity issues previously seen with anti-TNF drugs .
It is widely believed now that “vedolizumab can be used either as a first-line treatment or in case of anti-TNF failure”

Phase 1-Sangamo Presents New Clinical Data at CROI 2013 Demonstrating Persistent Immune System Improvements After Treatment With ZFN Therapeutic(R) SB-728-T

The gene therapy diminished the levels of virus and eradicated in patients having naturally occurring mutation of gene, found a preliminary trail of HIV treatment. The first phase of very small trail tested the SB-728-T gene treatment that is intended to interrupt theCCR5 gene used by HIV to contaminate immune system cells.
The first clinical trial using zinc-finger nucleases to provide long-term resistance to HIV-1 infection has been given the go-ahead by the US Food and Drug Administration. Sangamo BioSciences of Richmond, California, and its clinical partner, the University of Pennsylvania, have begun enrolling the first 12 people in a phase 1 clinical trial to evaluate SB-728-T, a novel zinc-finger DNA-binding nuclease that permanently disrupts the CCR5 gene on CD4+ T cells (Nat. Biotechnol. 26, 808–816, 2008
Data Demonstrate that SB-728-T Possesses Necessary Immunologic Properties to Support a ‘Functional Cure’ for HIV/AIDS
RICHMOND, Calif., March 6, 2013
Sangamo BioSciences, Inc. announced new data from its program to develop a ‘functional cure’ for HIV/AIDS in two presentations at the 20th Conference on Retroviruses and Opportunistic Infections (CROI), held in Atlanta from March 3 to 6, 2013.
The first presentation described data from the SB-728-T Phase 1 study (SB-728-902, Cohorts 1-3) demonstrating that SB-728-T treatment of HIV-infected subjects leads to durable reconstitution of the immune system driven by increases in total CD4+ central memory T-cells (TCM) and CCR5-protected TCM. TCM are long-lived, self-renewing cells that have the ability to remember and react against foreign antigens including HIV. The data also showed that certain cell surface marker and gene expression profiles may predict which patients will likely respond best to SB-728-T treatment.

Phase III Study of Oral Laquinimod for Relapsing-Remitting Multiple Sclerosis
Laquinimod
5-chloro-N-ethyl-4-hydroxy-1-methyl-2-oxo-
N-phenyl-1,2-dihydroquinoline-3-carboxamide
Laquinimod is an experimental immunomodulator developed by Active Biotech and Teva. It is currently being investigated as an oral treatment for multiple sclerosis (MS).
Laquinimod is the successor of Active Biotech’s failed experimental immunomodulator linomide.[1]
The compound has been investigated in two Phase II trials using successive magnetic resonance scans (MRI). Laquinimod seems to be able to reduce the MS disease activity on MRI.[2][3] However, the response to a given dose was discrepant between both studies.[4]
Phase III studies for MS started in December 2007.[5] In 2011, Teva announced its clinical trials involving laquinimod had failed, being unable to significantly reduce relapses into MS among patients beyond a placebo.[6] However, the final results of above mentioned phase III trial proved oral laquinimod administered once daily slowed the progression of disability and reduced the rate of relapse in patients with relapsing–remitting multiple sclerosis [7]
Mar 6, 2013 –
CONCERTO Study Enrolling Patients Globally to Evaluate Impact of Laquinimod on Disability Progression
Teva Pharmaceutical Industries Ltd. and Active Biotech announced today enrollment of the first patient in the CONCERTO study – the third Phase III placebo-controlled study designed to evaluate the efficacy, safety and tolerability of once-daily oral laquinimod in patients with relapsing-remitting multiple sclerosis (RRMS). The primary outcome measure of CONCERTO will be confirmed disability progression as measured by the Expanded Disability Status Scale (EDSS).
“Previous Phase III studies in more than 2,400 people with RRMS suggest a unique profile of laquinimod, directly affecting the neurodegenerative processes that lead to disability progression, the main concern in the treatment of RRMS,” said CONCERTO principal investigator, Dr. Timothy Vollmer, Professor of Neurology, University of Colorado Denver, Medical Director of the Rocky Mountain Multiple Sclerosis Center, and Co-Director of the RMMSC at Anschutz. “We are currently enrolling patients in this third pivotal study to further examine the clinical benefits of laquinimod on disability progression, the primary endpoint of the CONCERTO trial, and brain atrophy, at both the previously studied 0.6 mg dose, and now a higher 1.2 mg dose.”
The multinational, randomized, double blind placebo-controlled study will aim to enroll approximately 1,800 patients at more than 300 sites globally (http://clinicaltrials.gov/show/NCT01707992). Along with the primary endpoint of time to confirmed disability progression, the study will also examine the impact of laquinimod on endpoints such as percent change in brain volume and other clinical and MRI markers of disease activity.
“For nearly 30 years, Teva has been focused on improving the lives of people with multiple sclerosis by delivering innovative treatment options that address this complex disease,” said Dr. Michael Hayden, President of Global R&D and Chief Scientific Officer at Teva Pharmaceutical Industries Ltd. “The CONCERTO study demonstrates our commitment to collaborating with MS communities worldwide to further develop laquinimod and address unmet patient needs.”
ABOUT LAQUINIMOD
Laquinimod is an oral, once-daily CNS-active immunomodulator with a novel mechanism of action being developed for the treatment of MS. In animal models laquinimod crosses the blood brain barrier to potentially have a direct effect on resident CNS inflammation and neurodegeneration. The global Phase III clinical development program evaluating oral laquinimod in MS includes two pivotal studies, ALLEGRO and BRAVO.
In addition to the MS clinical studies, laquinimod is currently in clinical development for Crohn’s disease and Lupus.
ABOUT CONCERTO
CONCERTO is a multinational, multicenter, randomized, double-blind, parallel-group, placebo-controlled study followed by an active treatment phase, to evaluate the efficacy, safety and tolerability of two doses of oral administration of laquinimod 0.6 mg/day or 1.2 mg/day in subjects with RRMS. This third Phase III laquinimod study will evaluate laquinimod in approximately 1,800 patients for up to 24 months, after which patients will continue to an active treatment period with laquinimod for an additional 24 months. The primary outcome measure will be time to confirmed disability progression as measured by the Expanded Disability Status Scale (EDSS). The study will also examine the impact of laquinimod on endpoints such as percent change in brain volume, as well as other clinical and MRI markers of disease activity.
ABOUT MULTIPLE SCLEROSIS
MS is the leading cause of neurological disability in young adults. It is estimated that more than 400,000 people in the United States are affected by the disease and that two million people may be affected worldwide. Multiple sclerosis is a degenerative disease of the central nervous system in which inflammation and axonal damage and loss result in the development of progressive disability.

Description of LOR-253, LT253: LOR-253 HCl is the hydrochloride salt of a small molecule inhibitor of human metal-regulatory transcription factor 1 (MTF-1) with potential antitumor activity. MTF-1 inhibitor LOR-253 inhibits MTF-1 activity and thereby induces the expression of MTF-1 dependent tumor suppressor factor Kruppel like factor 4 (KLF4). This subsequently leads to the downregulation of cyclin D1, blocking cell cycle progression and proliferation. This agent also causes decreased expression of genes involved in tumor hypoxia and angiogenesis.

March 5, 2013
Progenics Pharmaceuticals, Inc. (Nasdaq:PGNX) reported positive clinical data from a study of two novel radiolabeled small molecules targeting prostate-specific membrane antigen (PSMA). The imaging agents — 123I-MIP-1072 and 123I-MIP-1095 — had a high sensitivity of lesion detection in bone, tissue and the prostate gland with minimal retention in non-target tissue. The research was published as the cover article in the March issue of The Journal of Nuclear Medicine.
“Existing imaging techniques are limited in their ability to diagnose and stage prostate cancer,” said John J. Babich, Ph.D., senior author of the article “First-in-Man Evaluation of Two High-Affinity PSMA-Avid Small Molecules for Imaging Prostate Cancer.” “The approach described in this paper has the potential to assess disease status more accurately. It could help clinicians select optimal treatments and lead to better patient outcomes.”
Separate phase 1 studies were conducted under an exploratory investigational new drug (IND) application to measure the potential effectiveness of the small molecules in diagnosing and staging prostate cancer. In the first study, seven patients with documented prostate cancer were administered doses of 123I-MIP-1072 and 123I-MIP-1095, two weeks apart. In the second study, six healthy volunteers received 123I-MIP-1072 only. Whole body planar imaging and single photon emission computed tomography (SPECT)/computed tomography (CT) were performed for each group, and pharmacokinetics, tissue distribution, excretion, safety and organ radiation dose were analyzed.
Based on the data reported, Progenics is conductinga global, multi-center phase 2 trial investigating a next generation radiolabeled small molecule targeting PSMA, MIP-1404.
Mark R. Baker, chief executive officer of Progenics, said, “We recently acquired all of the rights to the compounds described in this Journal of Nuclear Medicine paper, as well as to the phase 2 stage imaging agent MIP-1404, through Progenics’ acquisition of Molecular Insight Pharmaceuticals. It is gratifying to see this expansion of our oncology pipeline demonstrating progress so soon.”
Robert J. Israel, M.D., Progenics’ senior vice president of medical affairs and clinical research, said, “We believe that MIP-1404 has excellent potential as a diagnostic radiopharmaceutical. Results to date from the study compounds and MIP-1404 show PSMA as a robust target for prostate cancer molecular imaging, and that a radiolabeled small molecule, which binds PSMA with high affinity, has the potential to detect prostate cancer throughout the body. Cancer treatment guidelines call for imaging prostate cancer with conventional bone scans or MRI. A more accurate method of imaging prostate cancer could be of great value.”
Mr. Baker further added, “Thought leaders in prostate cancer care are focused on avoiding unnecessary surgery and other invasive procedures due to the complications associated with them. Clinicians generally prefer “watchful waiting” when the cancer appears to be indolent. At the same time, some therapeutics to treat aggressive prostate cancer have recently been approved or are under development, such as Progenics’ own PSMA ADC, which currently is in phase 2 testing. Patients and their physicians would benefit from feedback on how therapeutic agents are impacting the course of cancer, and guidance on how and when to use therapeutic agents. It is clear that an improved way to visualize prostate cancer, with a high degree of specificity and sensitivity, would better inform both “watchful waiting” and the treatment of aggressive disease. We believe that data from the ongoing phase 2 trial of MIP-1404 will demonstrate its capabilities to assist prostate cancer patients and their physicians in making these critical decisions.”

Durata Therapeutics, Inc. has announced preliminary, top-line results for its DISCOVER 2 (“Dalbavancin for Infections of the Skin COmpared to Vancomycin at an Early Response”) Phase III study of dalbavancin, which is under investigation for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible gram-positive bacteria, including methicillin resistant Staphylococcus aureus (MRSA).

Vital 5 Receives Clearance from the FDA for a First-To-Market, Dual Function Catheter System that Provides Simultaneous Anesthetic Infusion and Wound Drainage, ReLeaf™
Mar 6, 2013 ,
Vital 5, LLC, a VentureMD portfolio company, announces that it has received clearance from the U. S. Food and Drug Administration (FDA) for ReLeaf™, a first-to-market, dual function catheter system that provides simultaneous anesthetic infusion and wound drainage.
Continuous anesthetic infusion to the surgical site in the immediate post-operative period has been clinically proven to provide significant improvements to pain management, but this therapy is currently not compatible with the millions of surgical cases where a wound drain is prescribed. By offering an integrated system that provides effective continuous local anesthetic infusion while also providing an effective wound drain function, the Vital 5 ReLeaf will greatly expand the number of patients who can benefit from local anesthetic infusion therapy.
The clinical applications for the Vital 5 ReLeaf include any invasive surgical procedure, including spine, orthopedic, cardiothoracic, plastic, general, obstetrics and gynecological procedures.
