Creative Peptides to Reorganize Its Peptide Synthesis Services for Science Community

Creative Peptides announced to reorganize its peptide synthesis services.

Shirley, New York (November 21, 2018) One of the world’s leading peptide suppliers Creative Peptides announced to reorganize its peptide synthesis services on November 21, 2018. Now this business is distinctively divided into three categories, namely, custom peptide design, custom peptide synthesis and GMP grade peptide synthesis.

As the pharmaceutical industry develops rapidly, there are an increasing demand for peptide synthesis. And with the discovery of biologically active peptides, the objectives of synthesis also change dramatically.

“Peptide design is the very first step of any meaningful studies about proteins and peptides. During this step, several factors such as the length of sequence, amino acid residues and the sequence of peptides need to be carefully considered as they are vital to correct assembly and purification. So we generally adopt some strategies to design peptide better,” explains Dr. Robert Martinez, head of Creative Peptides’ synthesis businesses, in a statement.

When everything gets prepared, a peptide synthesis project is initiated. “There are two types of peptide synthesis: solid phase synthesis and liquid phase synthesis. And in fact, the solid phase synthesis method has become a kind of common technique in the synthesis of peptides and proteins,” further expounds Dr. Robert. “In addition, all products synthesized by Creative Peptides meet GMP standards as all our production sites were designed in strict accordance to US-FDA guidelines for GMP Manufacturing.”

Peptide synthesis has proven to be useful in the following applications:

Biological effect measurements;

Peptide array and microarray printing;

Enzymology and biological activity screening;

Vaccine development;

Receptor characterization and receptor-ligand interactions;

Mass spec standard development and studies;

Protein function-structure analysis;

Peptide for drug discovery;

Therapeutic peptide drugs;

Biophysical studies;

Scientists Repurpose Wasp Venom Peptides to Fight Drug-Resistant Bacteria

After performing an analysis of the antimicrobial properties of a peptide found in the venom of Polybia paulista, a species of South American social wasp, a team of researchers at MIT has engineered several variants of the peptide that are potent against bacteria but nontoxic to human cells. In a study of mice, the team found that their strongest peptide could completely eliminate Pseudomonas aeruginosa, a strain of bacteria that causes respiratory and other infections and is resistant to most antibiotics.

As part of their immune defenses, many organisms produce peptides that can kill bacteria.

To help fight the emergence of antibiotic-resistant bacteria, many scientists have been trying to adapt these peptides as potential new drugs.

A peptide isolated from the venom of Polybia paulista is small enough — only 12 amino acids — that MIT researcher Cesar de la Fuente-Nunez and co-authors believed it would be feasible to create some variants of the peptide and test them to see if they might become more potent against microbes and less harmful to humans.

“It’s a small enough peptide that you can try to mutate as many amino acid residues as possible to try to figure out how each building block is contributing to antimicrobial activity and toxicity,” Dr. de la Fuente-Nunez said.

Like many other antimicrobial peptides, this venom-derived peptide, named Polybia-CP (Pol-CP-NH2: Ile-Leu-Gly-Thr-Ile-Leu-Gly-Leu-Leu-Lys-Ser-Leu-NH2), is believed to kill microbes by disrupting bacterial cell membranes. It has an alpha helical structure, which is known to interact strongly with cell membranes.

In the first phase of the study, Dr. de la Fuente-Nunez and colleagues created a few dozen variants of the Polybia-CP peptide and then measured how those changes affected the peptides’ helical structure and their hydrophobicity, which also helps to determine how well the peptides interact with membranes.

The researchers then tested these peptides against seven strains of bacteria and two of fungus, making it possible to correlate their structure and physicochemical properties with their antimicrobial potency.

Based on the structure-function relationships they identified, they then designed another few dozen peptides for further testing.

They were able to identify optimal percentages of hydrophobic amino acids and positively charged amino acids, and they also identified a cluster of amino acids where any changes would impair the overall function of the molecule.

To measure the peptides’ toxicity, the team exposed them to human embryonic kidney cells grown in a lab dish.

The scientists selected the most promising compounds to test in mice infected with Pseudomonas aeruginosa, a common source of respiratory and urinary tract infections, and found that several of the peptides could reduce the infection. One of them, given at a high dose, could eliminate it completely.

“After four days, that compound can completely clear the infection, and that was quite surprising and exciting because we don’t typically see that with other experimental antimicrobials or other antibiotics that we’ve tested in the past with this particular mouse model,” Dr. de la Fuente-Nunez said.

The research is published in the journal Communications Biology.

ArmaGen Receives U.S. Orphan Drug Designation for AGT-184

Calabasas, Calif., August 2, 2018 – ArmaGen, Inc., a privately held biotechnology company focused on developing groundbreaking therapies to treat severe neurological disorders, today announced that the U.S. Food and Drug Administration’s (FDA) Office of Orphan Products Development granted Orphan Drug Designation to GT-184 for the treatment of mucopolysaccharidosis type IIIA (also known as Sanfilippo Syndrome A or MPS IIIA). MPS IIIA is a lysosomal storage disease (LSD) that arises from a deficiency in the gene encoding for the enzyme N-sulfoglucosamine sulfohydrolase (SGSH), which results in a buildup of complex sugar polymers within the brain causing progressive intellectual disability and the loss of previously acquired skills (developmental regression).

AGT-184 is an IgG-SGSH fusion protein, where the IgG domain is a human anti-insulin receptor monoclonal antibody. The insulin receptor antibody domain triggers transport of the AGT-184 fusion protein across the blood brain barrier (BBB), via binding to endogenous insulin receptors present on the BBB. ArmaGen is currently conducting IND-enabling activities (manufacturing/toxicology) with the goal of filing an IND with the U.S. FDA in late 2019.

“We are very pleased to receive FDA orphan drug designation for AGT-184, as this designation is an important regulatory milestone for the Company as we work to develop a potential treatment option for patients suffering from this rare and life-threatening disease,” said Mathias Schmidt, Ph.D., Chief Executive Officer of ArmaGen. “This moment represents a transformational period in the Company’s evolution as we prepare to leverage our clinically validated BBB platform to advance additional pipeline assets.”

The FDA grants Orphan Drug Designation to drugs intended to treat a rare disease or condition affecting fewer than 200,000 people in the U.S. This designation confers special incentives to the drug developer, including tax credits on the clinical development costs, prescription drug user fee waivers and may entitle a period of seven-year market exclusivity in the US upon FDA approval.

In a mouse model of MPSIIIA, a surrogate version of AGT-184 (AGT-m184) showed activity in both CNS and somatic organs, further substantiating the applicability of ArmaGen’s Trojan Horse approach to MPS IIIA. Mice were treated three times per week for six weeks with AGT-m184. Compared to the control mice, there was a 70% reduction in brain heparan sulfate levels at the end of the six-week study, which provides direct evidence that the fusion protein crossed the BBB and delivered the SGSH enzyme payload into the brain. There was also an 85% reduction in liver heparan sulfate levels as compared to control, which is evidence of somatic or peripheral activity of the IgG-SGSH fusion protein.

About AGT-184
AGT‑184 is an investigational enzyme replacement therapy (ERT) for the treatment of the cognitive effects of Sanfilippo A syndrome, a lysosomal storage disease that arises from a deficiency in the gene encoding for the enzyme N-sulfoglucosamine sulfohydrolase (SGSH), which results in a buildup of complex sugar polymers in brain cells. Currently, there are no approved therapies for the treatment of Sanfilippo A syndrome. Unlike recombinant SGSH, which does not cross the BBB, AGT-184 is a re-engineered form of the SGSH enzyme that is able to penetrate the BBB, and which has the same enzyme activity of the native SGSH enzyme.

About ArmaGen
ArmaGen, Inc., is a privately held biotechnology company focused on developing groundbreaking therapies for severe neurological disorders. The company is developing a robust pipeline of innovative therapies for the treatment of lysosomal storage disorders including neurological symptoms such as Hurler syndrome (MPS I), Hunter syndrome (MPS II), metachromatic leukodystrophy, Sanfilippo A and B syndromes, as well as other diseases with severe CNS manifestations. ArmaGen’s pipeline is based on decades of scientific leadership in engineering therapies to cross the blood-brain barrier and a dominant intellectual property portfolio. The company is advancing its pipeline through licensing and collaboration agreements, in-house development programs, and other partnering opportunities. For more information, visit www.armagen.com.

Gritstone Oncology Announces Publication in Nature Biotechnology of Neoantigen Identification Capabilities of its Artificial Intelligence Platform, EDGE

EMERYVILLE, Calif., Dec. 17, 2018 (GLOBE NEWSWIRE) -- Gritstone Oncology, Inc. (Nasdaq: GRTS), a clinical-stage biotechnology company developing the next generation of cancer immunotherapies to fight multiple cancer types, today announced that data demonstrating the predictive performance of its EDGETM (Epitope Discovery in cancer GEnomes) platform in the identification of tumor-specific neoantigens (TSNA) and neoantigen-reactive T-cells was published in Nature Biotechnology.

Three distinct datasets were used in the manuscript to validate the EDGE platform as a robust machine-learning tool for neoantigen identification. First, the authors showed that EDGE increases the accuracy of predicting human leukocyte antigen (HLA)-presented peptides on tumor cells by up to nine-fold over industry-standard methods using relevant metrics. Second, independently validated neoantigens from published third-party studies (mostly from the U.S. National Cancer Institute) were used to compare the performance of EDGE versus public prediction tools. Using only patient tumor mutation data from these studies to predict neoantigens, EDGE correctly identified validated TSNA for 11 of 12 patients, versus only 4 of 12 patients identified with the standard approach. Finally, using routine blood samples obtained from nine non-small cell lung cancer patients receiving PD-(L)1 checkpoint inhibitors, EDGE enabled identification of circulating T-cells specific for true neoantigens in the majority of (5 of 9) patients.

“Neoantigens are critical targets of immunotherapy and can drive an effective anti-tumor T-cell response; yet, existing tools have had low success rates in identifying true neoantigens,” said Roman Yelensky, Ph.D., executive vice president and chief technology officer. “We built our EDGE platform to be a best-in-class machine-learning model using the largest dataset of HLA-presented peptides from human tumor samples. The data published in Nature Biotechnology support EDGE as a transformative tool for the development of the next generation of neoantigen-targeted cancer immunotherapies.”

“EDGE represents the cutting edge in personalized immunotherapy,” said Timothy Chan, M.D., Ph.D., co-founder and scientific advisory board member of Gritstone. “I am very excited to see this state-of-the-art technology used to improve neoantigen vaccine development.”

EDGE’s prediction model was trained using a large dataset of human tumor and normal tissue samples with paired class I HLA-presented peptide sequences, HLA types and transcriptome RNA sequencing. A variety of tumor types, such as breast, lung, melanoma, colon and ovarian cancers were collected for sequencing, and combined with publicly available data. The training dataset for EDGE has since grown to now include more than 300 tumor and normal tissue samples, yielding over one million peptides, from patients of various ancestries with diverse HLA types. In addition to the training dataset, a key differentiator that contributed to improved performance was a novel integrated neural network model architecture. This neural network enabled EDGE to jointly model multiple key features, such as variable peptide length and the dependence of peptide presentation on gene expression level using RNA, essential for accurate prediction of true TSNA. The United States Patent Office issued Gritstone its first patent covering EDGE, on August 21, 2018 (Yelensky, et al., Neoantigen identification, manufacture and use, US 10,055,540.).

About Gritstone Oncology
Gritstone Oncology (Nasdaq:GRTS), a clinical-stage biotechnology company, is developing the next generation of cancer immunotherapies to fight multiple cancer types. Gritstone develops its products by leveraging two key pillars—first, a proprietary machine learning-based platform, Gritstone EDGE™, which is designed to predict, from a routine tumor biopsy, the tumor-specific neoantigens (TSNA) that are presented on a patient’s tumor cells; and second, the ability to develop and manufacture potent immunotherapies utilizing patients’ TSNA to potentially drive the patient’s immune system to specifically attack and destroy tumors. The company’s lead product candidate, GRANITE-001, is a personalized neoantigen-based immunotherapy in Phase 1 clinical testing. Gritstone’s second product candidate, SLATE-001, is a shared neoantigen (“off-the-shelf”) immunotherapy which is advancing towards the clinic. Novel tumor-specific antigens can also provide targets for bispecific antibody (BiSAb) therapeutics for solid tumors, and Gritstone’s BiSAb program is currently in lead optimization.

CohBar Provides Update on CB4211 Clinical Trial

MENLO PARK, Calif., Nov. 05, 2018 (GLOBE NEWSWIRE) -- CohBar, Inc. (NASDAQ: CWBR), a clinical stage biotechnology company developing mitochondria based therapeutics (MBTs) to treat age-related diseases, announced today the Phase 1 clinical study of CB4211, its lead MBT candidate under development as a potential treatment for non-alcoholic steatohepatitis (NASH) and obesity, has been temporarily suspended in order to address mild injection site reactions that have been unexpectedly persistent.

“Patient safety is very important to us and is also the primary objective of our CB4211 Phase 1 clinical trial,” said Simon Allen, CohBar CEO. “While only mild adverse events have occurred in the study to date, we are taking the time to address these injection site reactions in order to reduce the risk of any safety or tolerability issues in the trial going forward. We continue to believe in the potential of this novel compound as a treatment for NASH and obesity, and the timely resolution of this issue is our top priority.”

“Mild injection site reactions are common in Phase 1 clinical studies of subcutaneously injected peptide drugs, and for most drugs they resolve quickly,” said Kenneth C. Cundy, PhD., CohBar CSO. “In general, what we have seen are persistent painless bumps that can be felt under the skin and in most cases would be otherwise undetectable. Information to date suggests that some of the CB4211 dose persists at the injection site. We have a plan to address this issue in the near term and are seeking regulatory feedback with the goal of resuming the clinical dosing of CB4211 as soon as possible.”

Ironwood Pharmaceuticals Announces FDA Fast Track Designation for Praliciguat for the Treatment of Heart Failure

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sep. 13, 2018-- Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD), a commercial biotech company, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for praliciguat (IW-1973) for the treatment of patients with heart failure with preserved ejection fraction (HFpEF). Praliciguat is an investigational, orally administered soluble guanylate cyclase (sGC) stimulator currently in Phase II clinical trials.

“An ever-increasing number of people are suffering from HFpEF, a disease characterized by exercise intolerance, frequent hospitalizations, and increased risk of death, yet there are no approved treatment options,” said Christopher Wright, M.D., Ph.D., senior vice president of global development and chief development officer of Ironwood. “We believe praliciguat has the potential to be a new treatment option for these patients and are researching its ability to provide multi-dimensional impact on this disease by increasing tissue blood flow and decreasing cardiac vascular inflammation and fibrosis. The Fast Track Designation underscores the seriousness of this disease and that praliciguat has potential to address unmet needs in HFpEF. We look forward to working closely with the FDA to rapidly progress the development of praliciguat for the treatment of HFpEF.”

The FDA grants Fast Track Designation to facilitate the development and expedite the review of drugs that have the potential to treat serious or life-threatening diseases. A drug granted Fast Track Designation is eligible for several benefits, including more frequent meetings with and communications from the FDA and potentially for Rolling Review of the New Drug Application (NDA) and Priority Review if relevant criteria are met.1

Ironwood is currently enrolling patients in a randomized, double-blind, placebo-controlled Phase II trial evaluating praliciguat for the potential treatment of HFpEF. Ironwood expects to enroll approximately 175 patients into the Phase II trial, which is designed to evaluate the safety and efficacy of praliciguat in patients with HFpEF. Topline data from this study are expected in the second half of 2019. Further details about the trial can be found at clinicaltrials.gov using the identifier number NCT03254485.

About Heart Failure with Preserved Ejection Fraction

Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure that occurs when the left ventricle becomes stiff and its ability to relax is reduced, causing the heart to be unable to fill with blood sufficiently. HFpEF affects an increasing number of people in the developed world, likely due to an increase in common risk factors such as old age, hypertension, and obesity.

About Praliciguat

Praliciguat (IW-1973), an investigational, oral, once-daily soluble guanylate cyclase (sGC) stimulator, is being studied in patients with diabetic nephropathy and in patients with heart failure with preserved ejection fraction (HFpEF). Diabetic nephropathy affects an estimated eight million Americans and 20 to 40 percent of all diabetic patients worldwide. It is the leading cause of end-stage renal disease. Currently available products do not treat the underlying pathophysiology of the disease or fully address the needs of this patient population. HFpEF affects an estimated three million Americans and 40 to 70 percent of heart failure patients worldwide. It is a highly symptomatic condition with high rates of morbidity and mortality that can cause insufficient delivery of oxygen to the tissues, fluid in the lungs and edema of the extremities, causing patients to be short of breath and have compromised exercise tolerance. There are no approved therapies to treat HFpEF.

Currently in Phase II development for diabetic nephropathy and for HFpEF, praliciguat has the potential to address the underlying causes of these devastating diseases by improving nitric oxide (NO) signaling, which may improve vascular and metabolic function and decrease the inflammatory and fibrotic consequences associated with these diseases.

About Ironwood's sGC Program

As a pioneering expert in cyclic GMP (cGMP), Ironwood is building on its success with linaclotide, which stimulates guanylate cyclase-C in the intestine, to develop a pipeline of soluble guanylate cyclase (sGC) stimulators. sGC plays an important role in regulating diverse physiological processes; dysregulation of sGC may play a role in multiple serious diseases. Ironwood's sGC stimulators are believed to harness the nitric oxide (NO)/sGC/cGMP pathway by working synergistically with NO to improve blood flow and metabolism and decrease inflammation and fibrosis.

Ironwood is advancing praliciguat (IW-1973) for the potential treatment of diabetic nephropathy and of heart failure with preserved ejection fraction (HFpEF). Olinciguat (IW-1701) is being developed for the potential treatment of achalasia and of sickle cell disease. In addition, Ironwood has a pipeline of other sGC stimulators in pre-clinical development.

About Ironwood Pharmaceuticals

Ironwood Pharmaceuticals (Nasdaq: IRWD) is a commercial biotechnology company focused on creating medicines that make a difference for patients, building value for our fellow shareholders, and empowering our passionate team. We are currently commercializing two innovative primary care products: linaclotide, the U.S. branded prescription market leader for adults with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC), and lesinurad, which is approved to be taken with a xanthine oxidase inhibitor (XOI), or as a fixed-dose combination with allopurinol, for the treatment of hyperuricemia associated with gout. We are also advancing a pipeline of innovative product candidates in areas of significant unmet need, including persistent gastroesophageal reflux disease, diabetic nephropathy, heart failure with preserved ejection fraction, achalasia and sickle cell disease. Ironwood was founded in 1998 and is headquartered in Cambridge, Mass.

Amicus Therapeutics Announces First Patient Dosed in Phase 3 PROPEL Pivotal Study of AT-GAA in Patients with Pompe Disease

Global Study to Assess AT-GAA Compared to Standard-of-Care Enzyme Replacement Therapy (ERT) over 52 Weeks

CRANBURY, NJ, USA (December 20, 2018) Amicus Therapeutics (Nasdaq: FOLD), a global biotechnology company focused on discovering, developing and delivering novel medicines for rare metabolic diseases, today announced the dosing of the first patient in a global phase 3 clinical study (ATB200-03, or PROPEL) of AT-GAA in adult patients with late onset Pompe disease. PROPEL is a 52-week, double-blind randomized study designed to assess the efficacy, safety and tolerability of AT-GAA compared to the current standard of care, alglucosidase alfa, an enzyme replacement therapy (ERT).

All participants randomized to AT-GAA in the PROPEL study will receive drug manufactured at the 1000L scale intended for clinical and commercial supply. Amicus also expects to initiate a smaller, open-label study of AT-GAA in pediatric patients in 2019.

“The initiation of our global PROPEL study is a true example of our capabilities to discover, develop and manufacture promising therapies, and deliver them to patients as quickly as we can,” said John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc. “With the first patient treated in this important study, we are now able to provide access to AT-GAA to many more adults with late onset Pompe disease. Importantly, this study is the first to offer AT-GAA manufactured at our commercial scale following many years of diligent work on the CMC and manufacturing side to produce biocomparable material that we can now supply for the study and future global Pompe population. People living with Pompe disease are urgently seeking new options, and we hope that the treatment experience in this study will enable global regulatory submissions.”

Pompe disease is an inherited lysosomal storage disorder caused by a deficiency of the enzyme acid alpha-glucosidase (GAA). Reduced or absent levels of GAA leads to the accumulation of glycogen in cells and causes progressive muscle weakness throughout the body, affecting several vital tissues of the body. AT-GAA is an investigational therapy that consists of ATB200, a unique recombinant human acid alpha-glucosidase (rhGAA) enzyme with optimized carbohydrate structures, particularly mannose-6 phosphate (M6P), to enhance uptake, co-administered with AT2221, a pharmacological chaperone.

Tahseen Mozaffar, MD, Professor and Chair of Neurology and Director, Neuromuscular Program at UC Irvine and Principal Investigator in the PROPEL study stated, “The PROPEL study provides us with the opportunity to build upon the very compelling data set from the earlier Phase 1/2 clinical study. The PROPEL study is well-designed, with an active comparator arm and several important assessments of efficacy, including the gold standard six-minute walk test. I look forward to treating more patients with AT-GAA in this study.”

The PROPEL study is expected to enroll approximately 100 participants (ERT-experienced and ERT-naïve) at up to 90 global sites. Participants will be randomized 2:1 to receive investigational AT-GAA (ATB200 co-administered with the oral chaperone AT2221) or standard of care ERT co-administered with an oral placebo for a 52-week double-blind primary treatment period. Following this primary treatment period, all participants will be eligible to receive AT-GAA in a long-term, open-label extension study.

The PROPEL study is designed to assess superiority of AT-GAA compared to alglucosidase alfa. The primary efficacy endpoint is change in six-minute walk distance from baseline to Week 52. Secondary endpoints include respiratory measures and additional measures of muscle function and muscle strength. More information, including a list of participating sites, is available at www.clinicaltrials.gov: NCT03729362.

AzurRx BioPharma Announces Initiation of Phase II OPTION Clinical Trial of MS1819-SD in Cystic Fibrosis Patients
  • First site initiated at the Cystic Fibrosis Institute
  • Initial top line data expected in 2019
  • NEW YORK, NY, USA (December 19, 2018) AzurRx BioPharma, Inc. (NASDAQ:AZRX) (“AzurRx” or the “Company”), a company specializing in the development of non-systemic, recombinant therapies for gastrointestinal diseases, today announced that it has initiated the Company's Phase II OPTION study to investigate MS1819-SD in cystic fibrosis (CF) patients with exocrine pancreatic insufficiency (EPI).

    The Phase II multi-center study is designed to investigate the safety, tolerability and efficacy of MS1819-SD in a head-to-head comparison against the current porcine enzyme replacement therapy standard of care. Planned enrollment is expected to include approximately 30 CF patients, with study completion anticipated in 2019.

    Key highlights of OPTION include:

    Six-week non-inferiority, coefficient of fat absorption (CFA) primary endpoint comparing MS1819-SD to porcine enzyme replacement therapy in patients with exocrine pancreatic insufficiency due to cystic fibrosis; Cross-over study design leverages input from the U.S. Food and Drug Administration (FDA) and the CF community;Target enrollment of approximately 30 patients 18 years of age and older; and
    Initial results expected during 2019.

    “We are delighted to serve as the first site initiated in the OPTION study,” commented Steven R. Boas, M.D., FAAP, FACCP, President and CEO, The Cystic Fibrosis Institute. “I believe that MS1819-SD has the potential to improve the lives of patients by reducing their pill burden, which can be as high as 40 digestive enzyme pills per day. Based on my 27 years of experience in treating CF patients, chronic digestive issues are often cited as one of their top concerns, which is also supported by the literature. MS1819-SD may offer a promising solution for this important unmet need.”

    Thijs Spoor, Chief Executive Officer of AzurRx, added, “The initiation of the OPTION study of MS1819-SD in patients with CF is a significant milestone for AzurRx and follows our successful Phase II EPI trial in patients with chronic pancreatitis, which demonstrated both safety and statistically significant efficacy. We look forward to this trial and to demonstrating it can make a meaningful difference for patients.”

    Dr. James Pennington, Chief Medical Officer of AzurRx, added, “We are very appreciative of the input provided by the FDA in designing our cross-over study and the positive feedback from the Cystic Fibrosis Foundation’s Therapeutics Development Network, which enables us to access its 89 accredited U.S. care centers.”

    As recently announced, in a Phase II trial in the chronic pancreatitis setting, MS1819-SD showed a favorable safety profile with good tolerability. Additionally, a statistically significant (p=0.002) improvement in the coefficient of fat absorption of 21.8% was observed the highest studied dose (per protocol).

    About OPTION

    The OPTION trial is a Phase II, open-label, multicenter, 2x2 crossover study assessing the safety and efficacy of MS1819-SD versus porcine PERT given at the same dose that was being administered during the pre-study period. Approximately 30 evaluable patients will complete both crossover periods. The primary efficacy endpoint will be a comparison of CFAs after each of the two crossover periods.

    Lonza to Establish Strategic Biomanufacturing Base in China Using GE Healthcare Solution

    Basel (CH) and Guangzhou (CN), 10 December 2018 – Lonza today announced an agreement with GE Healthcare under which GE Healthcare will deliver a biologics facility to Lonza in Guangzhou (CN). As the facility is part of a larger biomanufacturing initiative between GE Healthcare and Guangzhou Development District (GDD), the agreement will be finalized when contracts have been signed with the GDD. Later today, Lonza will sign a memorandum of understanding with the GDD to take the project forward. The new facility will give Lonza Pharma & Biotech a strategic base in China to respond to growing demand for high-quality CDMO services in the country.

    By working with GE Healthcare to develop the new facility, based on the KUBio platform, an off-the-shelf biologics factory, Lonza intends to offer its suite of antibody development services and manufacture GMP-certified batches by 2020. The two companies will work closely on the design of the 17,000m2 site, which will include 6,500m2 of lab space and one KUBio facility.

    The labs will house Lonza’s proprietary platforms for cell-line construction, including the GS Gene Expression System®, as well as process development, cell banking and pilot labs. The KUBio unit will enable small-scale GMP manufacturing equipped with GE Healthcare’s single-use biomanufacturing technologies, including 1,000 and 2,000L bioreactors, combined with Lonza’s automation platforms for clinical and early-commercial supply.

    “This partnership is the ideal way for Lonza to bring our expertise and technology to China,” said Marc Funk, COO Lonza Pharma & Biotech. “The combination of a strong and experienced technology provider with a long history in China, together with a dynamic regional authority, means that we can rapidly offer services to customers and ultimately get innovative therapies to patients more quickly.”

    GE Healthcare is working with the GDD to support large-scale manufacturing of biopharmaceuticals in China.

    “With Lonza coming on site, a hub of biotech is truly taking shape,” said Emmanuel Ligner, President and CEO, GE Healthcare Life Sciences. “This agreement is yet another step in realizing our vision of enabling and supporting manufacturers of all sizes to quickly deploy capacity and meet increasing customer demand for biologics.”

    The facility in China will extend Lonza Pharma & Biotech’s global biologics network that provides development and manufacturing services from gene through IND and BLA to mature commercial supply. In addition to the new Chinese site, the network comprises small-, mid- and large-scale assets in Switzerland, the United States, the UK, Spain and Singapore.

    Lonza plans to hire and train more than 160 staff, and the new site will benefit from the company’s global standards of technological and operational excellence. With more than 20 successful FDA approvals for biologics, combined with international regulatory expertise, Lonza will now be able to offer the same high standards in China as it does elsewhere.

    China has been historically underserved by biologics, but demand for antibody therapies is expected to grow significantly over the coming years. A strong scientific base and commercial instruments put into place by the Chinese authorities are encouraging their domestic companies developing innovative therapies for the global market, as well as multinationals with manufacturing requirements in the country. In particular, national rollout of the Marketing Authorization Holder scheme by 2019 paves the way for dedicated CDMO services in China.
