Atlanta Based Nonprofit CureCP.Org Announces 1st of Its Kind UTHealth Study for Cerebral Palsy Has Begun

The charitable nonprofit Let’s Cure CP (http://www.CureCP.org) is the only parent led advocacy group for Cerebral Palsy families whose sole purpose is to raise funds for research.

www.CureCP.org

A total of 30 children between the ages of 2 and 10 who have Cerebral Palsy will be enrolled.

(PRWEB) December 17, 2013

As one of the primary fund-raisers and promoters of this trial, CureCP.org is an honored collaborator and is very proud to announce that the first-of-its-kind clinical trial studying two forms of stem cell treatments for children with cerebral palsy (CP) has begun at The University of Texas Health Science Center at Houston (UTHealth) Medical School.

The double-blinded, placebo-controlled study’s purpose includes comparing the safety and effectiveness of banked cord blood to bone marrow stem cells. It is led by Charles S. Cox, Jr., M.D., the Children’s Fund, Inc. Distinguished Professor of Pediatric Surgery at the UTHealth Medical School and director of the Pediatric Trauma Program at Children’s Memorial Hermann Hospital. Co-principal investigator is Sean I. Savitz, M.D., professor and the Frank M. Yatsu, M.D., Chair in Neurology in the UTHealth Department of Neurology.

The study builds on Dr.Cox extensive research studying stem cell therapy for children and adults who have been admitted to Children’s Memorial Hermann and Memorial Hermann-Texas Medical Center after suffering a traumatic brain injury (TBI). Prior research, published in the March 2010 issue of Neurosurgery, showed that stem cells derived from a patient’s own bone marrow were safely used in pediatric patients with TBI. Cox is also studying cord blood stem cell treatment for TBI in a separate clinical trial.

A total of 30 children between the ages of 2 and 10 who have CP will be enrolled: 15 who have their own cord blood banked at Cord Blood Registry (CBR) and 15 without banked cord blood. Five in each group will be randomized to a placebo control group. Families must be able to travel to Houston for the treatment and followup visits at 6, 12 and 24 months.

Parents will not be told if their child received stem cells or a placebo until the 12-month follow-up exam. At that time, parents whose children received the placebo may elect to have their child receive the stem cell treatment through bone marrow harvest or cord blood banked with CBR.

Collaborators for the study include Let’s Cure CP, CBR, TIRR Foundation and Children’s Memorial Hermann Hospital.

Ventana Announces HER2 Companion Diagnostic to Identify Breast Cancer Patients for Roche’s Latest Targeted Medicines

Posted on by

Ventana Medical Systems, Inc. (Ventana), a member of the Roche Group, has announced the VENTANA HER2/neu (4B5) Rabbit Monoclonal Primary Antibody assay as a companion diagnostic1 for detecting HER2 protein expression for patients who, in countries where they are approved, may be appropriate candidates for Perjeta® (pertuzumab) and Kadcyla™ (ado-trastuzumab emtansine). Previously, the VENTANA HER2 (4B5) test was labeled only for the identification of HER2-positive breast and gastric cancer patients for whom Herceptin® (trastuzumab) treatment is being considered.

“In line with our mission to improve the lives of all patients afflicted with cancer, our HER2 assay will continue to provide important diagnostic information for breast cancer treatment decisions,” says Mara G. Aspinall, President, Ventana Medical Systems, Inc. “We are proud to be the preferred tissue diagnostics partner for our Roche Pharma colleagues. This announcement also signifies the unique ability of Roche to deliver healthcare to cancer patients worldwide.”

Breast cancer is the most common cancer worldwide for women2 and the second leading cause of female cancer-related deaths3. Approximately one-fifth of breast cancers are classified as HER2- positive and if left untreated are associated with poorer clinical outcomes4. Defining HER2 status allows the treatment team to better identify which patients may be appropriate candidates for a treatment regimen with a HER2 targeted medicine.

“Ventana is a global leader in companion diagnostics. Our HER2 diagnostics portfolio, including both the VENTANA IHC and INFORM HER2 Dual ISH assays, is the market leader in terms of automation, medical value and customer adoption,” says Doug Ward, Vice President, Companion Diagnostics, Ventana Medical Systems, Inc. “We are working to enable the VENTANA HER2 (4B5) IHC companion diagnostic assay in all markets where Perjeta and Kadcyla are available for therapy, bringing this technology to physicians and patients worldwide.”

In addition to Roche, Ventana has worked with more than 45 bio-pharmaceutical partners over the past decade and is currently engaged in over 150 collaborative projects to develop and commercialize companion diagnostics globally.

For more than a decade, Herceptin (trastuzumab), a HER2-directed therapy, has been approved by health authorities for people with HER2-positive breast cancer. To further help build on the progress made with Herceptin, Roche has recently introduced two additional HER2-directed therapies, Perjeta (pertuzumab) and Kadcyla (ado-trastuzumab emtansine).

Perjeta® (pertuzumab) is approved for use in combination with Herceptin® (trastuzumab) and docetaxel chemotherapy in people with HER2-positive breast cancer that has spread to different parts of the body (metastatic) and who have not received anti-HER2 therapy or chemotherapy for metastatic disease.

Kadcyla™ (ado-trastuzumab emtansine) is approved for the treatment of people with HER2-positive metastatic breast cancer (mBC) who have received prior treatment with Herceptin® (trastuzumab) and a taxane chemotherapy. People should either have already been treated for their metastatic cancer or have had their early-stage cancer come back during or within six months after they completed a course of treatment following surgery.

Herceptin is approved for the treatment of early-stage breast cancer that is Human Epidermal growth factor Receptor 2-positive (HER2+) and has spread into the lymph nodes, or is HER2+ and has not spread into the lymph nodes. If it has not spread into the lymph nodes, the cancer needs to be estrogen receptor/progesterone receptor (ER/PR)-negative or have one high risk feature.* Herceptin can be used in several different ways:

• As part of a treatment course including the chemotherapy drugs doxorubicin, cyclophosphamide, and either paclitaxel or docetaxel. This treatment course is known as “AC®TH”
• With the chemotherapy drugs docetaxel and carboplatin. This treatment course is known as “TCH”
• Alone after treatment with multiple other therapies, including an anthracycline-based therapy (a type of chemotherapy)
*High risk is defined as ER/PR-positive with one of the following features: tumor size >2 cm, age

Herceptin has two approved uses in metastatic breast cancer:

• Herceptin in combination with the chemotherapy drug paclitaxel is approved for the first line treatment of Human Epidermal growth factor Receptor 2-positive (HER2+) metastatic breast cancer
• Herceptin alone is approved for the treatment of HER2+ breast cancer in patients who have received one or more chemotherapy courses for metastatic disease

Herceptin is approved, in combination with chemotherapy (cisplatin and either capecitabine or 5-fluorouracil), for the treatment of HER2+ metastatic cancer of the stomach or gastroesophageal junction (where the esophagus meets the stomach) in patients who have not received prior treatment for their metastatic disease.

1The VENTANA HER2 (4B5) IHC assay is a CE-IVD companion diagnostic available outside the U.S. Check with your local representative for availability in your area. VENTANA HER2/neu (4B5) Rabbit Monoclonal Primary Antibody is not available or approved for use in the United States.

Epidemic of Escherichia coli infections traced to one strain of bacteria

Fast-evolving lethal clone spreads worldwide, according to new study published today

FLAGSTAFF, Ariz., and WASHINGTON, D.C. — Dec. 17, 2013 — In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys, according to a study published today in the American Society for Microbiology’s open access journal mBio.

Besides becoming more resistant to antibiotics, the strain H30-Rx gained an unprecedented ability to spread from the urinary tract to the blood, leading to the most lethal form of bacterial infections — sepsis — and posing a looming threat to the more than 10 million Americans who annually suffer from urinary tract infections (UTIs).

This new study could help trace the evolutionary history of this superbug and possibly lead to the development of a vaccine, according to Lance B. Price, Ph.D., the study’s lead author.  Price is professor of environmental and occupational health at the George Washington University School of Public Health and Health Services (SPHHS), and is an associate professor in the Pathogen Genomics Division of the Translational Genomics Research Institute (TGen).

Previous research suggested that the ST131 group of E. coli – a family of many genetically related strains of bacteria — had independently gained resistance to antibiotics through separate genetic events. The ST131 group had been identified as a major source of superbugs — microbes resistant to multiple antibiotics — among UTI bacteria. If true, the existence of many different resilient strains would prove a formidable threat with multiple ways of evading the immune system and medical treatment, according to the new study.

Using advanced genomic techniques, Price and collaborators — James R. Johnson of the Veterans Affairs Medical Center and the University of Minnesota, and Evgeni V. Sokurenko of the University of Washington School of Medicine — discovered that the ST131 strains represented genetic clones abruptly evolved from a single strain of E. coli.

By gaining mutations in two genes, a strain called H30 gave rise more than a decade ago to the H30-R clone, which became fully resistant to the then-wonder-drug known as Cipro.  Soon after, a new clone evolved from H30-R called H30-Rx, which is resistant to several extended-spectrum antibiotics, such as third-generation cephalosporins.

Using whole-genome sequencing — spelling out, in order, each molecule of DNA — researchers analyzed the genomes of E. coli samples from patients and animals in five countries over 44 years, 1967-2011. They created a family tree tracing how the superbug clones emerged as the result of discrete genetic events.

“Astoundingly, we found that all of the resistance could be traced back to a single ancestor,” Price said. “Our research shows this superbug then took off, and now causes lots of drug-resistant infections.”

H30-Rx, appears to be much more adept than other E. coli at ascending from the bladder to the kidneys and then into the bloodstream, where it can be lethal, and the study suggests that H30-Rx may be responsible for 1.5 million UTIs and tens of thousands of deaths annually in the United States.

This study shows that, by focusing on H30-Rx, researchers might find a vaccine that could prevent many infections.  Vaccines for highly resistant strains of superbugs could protect people from ever getting sick in the first place, Price said.

“This strain of E. coli spreads from person to person and seems to be particularly virulent,” Johnson said. “This study might help us develop better tools to identify, stop or prevent its spread by finding better ways to block the transmission of the superbug, or by finding a diagnostic test that would help doctors identify such an infection early on — before it might have the chance to turn lethal.”

Sokurenko added, “We now know that we are dealing with a single enemy, and that by focusing on this strain we can have a substantial impact on this worldwide epidemic.”

The study, The epidemic of ESBL-producing Escherichia coli ST131 is driven by a single highly pathogenic subclone, H30-Rx, appears today in the peer-reviewed online-only scientific magazine mBio – the flagship journal of the American Society for Microbiology and the American Academy of Microbiology.

Venture Madness – a new kind of startup battle – applications open today

Venture Madness, presented by Invest Southwest in partnership with Arizona Commerce Authority, is a competition where 64 startups from around the southwest will go head-to-head and compete for a portion of the $25,000 prize.

For the last 20 years, Invest Southwest, has been the premier capital conference in the region connecting investors with ventures and has had an “investment-centric focus” format, until this year. The event has gone through a serious transformation by responding to the needs of its audience and embracing the vibrancy of the startup community, starting with Venture Madness.

How Venture Madness works: Think of it as the “Battle of the Brackets” where startups duel it out bracket-style for the top slot. Thirty-two (of 64) bracket spots will be awarded to past participants from the Arizona Innovation Challenge (AIC); the remaining 32 spots will be filled through open enrollment. Startups from the southwest can apply today, December 6, 2013, through January 3, 2014.

Once the 64 ventures are established, there will be two online elimination rounds and 16 companies will advance to the live-demo rounds before a panel of judges on March 5-7, at Talking Stick Resort in Scottsdale.

Jonathan Ariano, chairman of Invest Southwest and Partner with Osborn Maledon, explains the new format and vibe, “Before, we used to have 12-14 companies go through a mentoring process to produce a ten minute presentation, with no Q&A, nor a contest-it was more of an investment-centric conference. When we went through the revamping process, we started thinking like a startup and asked ourselves ‘who is our customer?’ and spent months brainstorming on what that looked like. What we realized is that there are great programs and incubators that help entrepreneurs, but what was missing was the connective tissue…and that’s our job. We will be the connection to the investor community and showcasing what the Southwest has to offer-and the best way we can do that is Venture Madness.”

As part of the Venture Madness event, the organizers have weaved in more investor and startup connection opportunities including lunch-n-learns, cocktail parties and a Spring Training outing.

“We are really excited about this new format,” said Ariano. “There are a lot of great companies in the Southwest and the level of quality just keeps going up.”

Hey startups! Open enrollment starts now! Companies interested in participation must complete the online application, as well as create and submit a 90-second elevator pitch video. Applications and more information for Venture Madness, including detailed instructions, are available online at http://VentureMadness.com.
