Penicillin Prevents Return of Leg Infection Called Cellulitis: Study
Penicillin core structure, where “R” is the variable group.
WEDNESDAY, May 1 (HealthDay News) — For people who have suffered from cellulitis of the leg, a long course of low-dose penicillin prevents the painful infection from returning, British researchers report.
Once the penicillin is stopped, however, its protective effect diminishes and the condition can flare up again, the researchers noted.

Daratumumab Receives Breakthrough Therapy Designation From US Food and Drug Administration
May 1, 2013
Genmab A/S announced today that the US Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for daratumumab for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent (IMiD) or who are double refractory to a PI and IMiD. Breakthrough Therapy Designation is a program intended to expedite the development and review of drugs to treat serious or life-threatening diseases in cases where preliminary clinical evidence shows that the drug may provide substantial improvements over available therapy. In August 2012, Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to develop and commercialize daratumumab.
Daratumumab is an investigational anti-cancer drug. It binds to CD38.Daratumumab was originally developed by Genmab, but it is now being jointly developed by Genmab along with the Johnson & Johnson subsidiary Janssen Biotech, which acquired worldwide commercialization rights to the drug from Genmab
The U.S. Food and Drug Administration today announced that it has approved an amended application submitted by Teva Women’s Health, Inc. to market Plan B One-Step (active ingredient levonorgestrel) for use without a prescription by women 15 years of age and older
April 30, 2013 — The U.S. Food and Drug Administration today announced that it has approved an amended application submitted by Teva Women’s Health, Inc. to market Plan B One-Step (active ingredient levonorgestrel) for use without a prescription by women 15 years of age and older.
After the FDA did not approve Teva’s application to make Plan B One-Step available over-the-counter for all females of reproductive age in December 2011, the company submitted an amended application to make the product available for women 15 years of age and older without a prescription.

Daiichi Sankyo enrolls first patient in Nimotuzumab Phase 3 clinical trials
Nimotuzumab
25 April 2013
Daiichi Sankyo Company, Limited announced today that the first patient has been enrolled in two pivotal phase 3 clinical trials of nimotuzumab (DE-766), a recombinant humanized monoclonal antibody targeting the Epidermal Growth Factor Receptor (EGFR), which is being evaluated for the treatment of patients diagnosed with lung cancer and with gastric cancer.
About Phase 3 Clinical Trials for Lung Cancer
The phase 3 clinical trial is a multicenter, randomized, double-blind, placebo-controlled study investigating nimotuzumab for the first-line therapy in patients with unresectable and locally advanced squamous cell lung cancer. The patients will receive either nimotuzumab in combination with concurrent chemoradiotherapy or placebo in combination with concurrent chemoradiotherapy. The primary endpoint is overall survival (OS), and the secondary endpoints are progression free survival (PFS) and safety. Approximately 420 patients are planned to be enrolled at approximately 60 clinical centers in Japan. Additional details of the trial are available onwww.clinicaltrials.jp/user/cteSearch.jsp.
About Phase 3 Clinical Trials for Gastric Cancer (ENRICH study)
The ENRICH study is a randomized, open-label, Japan-Korea collaborative study of previously treated patients with EGFR overexpressed advanced gastric and gastroesophageal junction cancer who will receive either nimotuzumab and irinotecan hydrochloride hydrate (hereafter, irinotecan) combination therapy or irinotecan monotherapy. The primary endpoint is overall survival (OS), and the secondary endpoints are progression free survival (PFS) and safety. Approximately 400 patients are planned to be enrolled at approximately 40 clinical centers in Japan and South Korea. In Korea, Kuhnil Pharmaceutical Company, Limited (hereafter, Kuhnil) is implementing this trial. Additional details of the trial are available on www.clinicaltrials.gov.
About Unresectable and Locally Advanced Squamous Cell Lung Cancer
In Japan, lung cancer is the first leading cause of cancer death, with about 70,000 deaths in 2011.i Non-small cell lung cancer (adenocarcinoma, squamous cell carcinoma, and large cell carcinoma) occupies more than 80 percent of lung cancer. Concurrent chemoradiotherapy for a radical cure is currently used as the standard treatment for patients with stage III locally advanced non-small cell lung cancer, in which radical surgery is not possible but radiotherapy is.ii Of these cases, between 30 and 40 percent are squamous cell carcinoma and EGFR is known to be overexpressed.iii
About Gastric Cancer
Half of the total number of gastric cancer cases worldwide occurs in Eastern Asia.iv In Japan, gastric cancer is the second leading cause of cancer death, with an estimated about 50,000 deaths. i In South Korea, about 10,000 gastric cancer deaths in 2011 were reported.v Numerous improvements have occurred in the management of gastric cancer; however, gastric cancer still has a poor prognosis. For patients with earlier stages of disease, more than 50% undergo surgery, but even after a curative resection, 60% of these patients eventually relapse locally or with distant metastases. vi
About Nimotuzumab and EGFR
Nimotuzumab is an intravenously administered recombinant humanized monoclonal antibody directed against human EGFR and is produced by CIMAB S.A. (Cuba). Nimotuzumab blocks the binding of EGF to its receptor interfering with the cell signaling pathway. Nimotuzumab has been approved for head and neck cancer, glioma, and esophageal cancer in several countries. EGFR is known to be overexpressed in a wide variety of human tumors.vii Overexpression of EGFR in tumors correlates with increased metastasis, decreased survival, and a poor prognosis. It is known that EGFR is activated by exposure to radiation.
In 2006, Daiichi Sankyo introduced nimotuzumab from CIMAB S.A. and CIMYM BioSciences Inc. (Canada) and has the rights to develop and commercialize in Japan. In Korea, Kuhnil has the rights to develop and commercialize.

A noninvasive avenue for Parkinson’s disease gene therapy
April 26, 2013
Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson’s disease (PD) in it tracks, preventing disease progression and reversing its symptoms.
The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain.
Parkinson’s is a devastating neurodegenerative disorder caused by the death of dopamine neurons in a key motor area of the brain, the substantia nigra (SN). Loss of these neurons leads to the characteristic tremor and slowed movements of PD, which get increasingly worse with time.
Currently, more than 1% of the population over age 60 has PD and approximately 60,000 Americans are newly diagnosed every year. The available drugs on the market for PD mimic or replace the lost dopamine but do not get to the heart of the problem, which is the progressive loss of the dopamine neurons.
The focus of Dr. Barbara Waszczak‘s lab at Northeastern University in Boston is to find a way to harvest the potential of glial cell line-derived neurotrophic factor (GDNF) as a treatment for PD. GDNF is a protein known to nourish dopamine neurons by activating survival and growth-promoting pathways inside the cells.
Bypassing the blood-brain barrier
Not surprisingly, GDNF is able to protect dopamine neurons from injury and restore the function of damaged and dying neurons in many animal models of PD. However, the action of GDNF is limited by its inability to cross the blood-brain barrier (BBB), thus requiring direct surgical injection into the brain.
To circumvent this problem, Waszczak’s lab is investigating intranasal delivery as a way to bypass the BBB. Their previous work showed that intranasal delivery of GDNF protects dopamine neurons from damage by the neurotoxin, 6-hydroxydopamine (6-OHDA), a standard rat model of PD.
Taking this work a step further, Brendan Harmon, working in Waszczak’s lab, has adapted the intranasal approach so that cells in the brain can continuously produce GDNF. His work utilized nanoparticles, developed by Copernicus Therapeutics, Inc., which are able to transfect brain cells with an expression plasmid carrying the gene for GDNF (pGDNF).
When given intranasally to rats, these pGDNF nanoparticles increase GDNF production throughout the brain for long periods, avoiding the need for frequent re-dosing.
Now, in new research presented at Experimental Biology 2013 in Boston, Harmon reported that intranasal administration of Copernicus’ pGDNF nanoparticles results in GDNF expression sufficient to protect SN dopamine neurons in the 6-OHDA model of PD.
Waszczak and Harmon believe that intranasal delivery of Copernicus’ nanoparticles may provide an effective and non-invasive means of GDNF gene therapy for PD, and an avenue for transporting other gene therapy vectors to the brain.
This work, which was funded in part by the Michael J. Fox Foundation for Parkinson’s Research and Northeastern University, has the potential to greatly expand treatment options for PD and many other central nervous system disorders.
