From Generics to Supergenerics

VLUU L110  / Samsung L110The significant contribution that generic drugs make to health services across Europe cannot be denied. As Nick Haggar, president of the European Generic medicines Association (EGA) pointed out during the 20th EGA Annual Conference, held in Madrid, 25–27 June 2014, the generic drug industry offers value to healthcare by providing increased medicines access to patients (hence, saving lives) while helping governments maximize their healthcare budgets. And these benefits are in addition to the employment and investment opportunities created.

A standard generic drug contains the same active ingredient as the original branded product and is used to treat the same condition at the same dose but at a price that is typically 20% to 90% less than the patented drug. The EGA estimates that generic drugs saves patients and European healthcare systems approximately EUR 35 billion each year. Read more »

NIH Translational Research Partnership Yields Promising Therapy

A potential treatment for sickle cell disease has come through the “valley of death” of early-stage development due to support from a collaborative partnership established by the National Center for Advancing Translational Sciences (NCATS) at the National Institutes of Health (NIH). The results of early clinical trials demonstrated sufficient effectiveness in addressing the underlying cause of this high-profile disease to attract commercial interest—in this case from Baxter International, which announced July 9, 2014 the acquisition of Massachusetts-based AesRx and its experimental drug Aes-103, a small-molecule, oral drug for sickle cell disease.

Delivering Complex Parenteral Formulations

Patricia Van Arnum PharmTech editorProgress in delivery science, manufacturing technologies, and commercialization are playing critical roles in advancing the development of complex parenteral drug formulations for new drug substances having a variety of formulation challenges. Unique formulation strategies and solutions are being investigated to extend the release of target peptides, proteins, nucleic acids, and small molecules for systemic, local, or cellular delivery. Pharmaceutical Technology will hold a live educational webcast, “Complex Parenteral Formulations for the Delivery of Peptides, Proteins, Nucleic Acids and Small Molecules,” on Thursday Nov. 21 from 10:00 to 11:00 AM EST, to examine the delivery science and product development of complex parenteral formulations.

Meeting Technical and Regulatory Requirements for Organic Impurity Control and Analysis

Patricia Van Arnum PharmTech editorProduct quality is of paramount importance to pharmaceutical manufacturers, and implementing a strategy for impurity control is crucial. Organic impurities cover a wide spectrum of compounds that have varying structures, behaviors, and characteristics. Organic impurities can result from the manufacturing process, storage conditions, or degradation resulting from light, heat, and other external factors. Deciding what technology or analytical methods to use to detect and measure organic impurities is a challenge. Pharmaceutical Technology will hold a live educational webcast, “Meeting Regulatory and Technical Requirements for Organic Impurity Analysis, on Tuesday Sept. 24 at 11:00 AM EDT to 12:00 PM EDT to provide insight on the regulatory, compendial, and ICH requirements for organic impurity control and analysis as well as best practices in analytical method development, method selection, and method validation for detecting and quantifying organic impurities in drug substances and drug products.

The panelists for the webcast will be: Timothy Watson, PhD, and research fellow in the GCMC Advisory Office at Pfizer and a member of the PhRMA Expert Working Group on the ICH Q11 regulatory guidance document for drug substances; Mark Argentine, PhD, senior research advisor, analytical sciences R&D with Eli Lilly; and Hildegard Bruemmer, PhD, operational laboratory manager, SGS Life Science Services, Berlin. The panelists will provide insight on the regulatory and compendial requirements for organic impurity control and analysis in drug substances and drug products. They will also share insight on selecting the appropriate analytical methods for the detection, analysis, and quantification of organic impurities and offer related case studies on how best to ensure product quality.

Audience members may ask questions of the panelists during the live webcast. Information on how to register for the webcast, “Meeting Regulatory and Technical Requirements for Organic Impurity Analysis” for Tuesday Sept. 24 at 11:00 AM EDT to 12:00 PM EDT and for on-demand viewing is available here.

FDA Offers Insight on QbD for Modified-Release Products

Patricia Van Arnum PharmTech editor FDA’s quality-by-design (QbD) initiative is a systematic approach to designing and developing pharmaceutical formulations and manufacturing processes to ensure predefined product quality. Understanding the critical quality attributes of the ingredients in a formulation, including excipients, and the critical process parameters in the manufacturing process of the finished drug product is crucial for successfully implementing QbD. Pharmaceutical Technology will be holding a live webcast on Thursday May 23 from 10:00 AM  to 11:00 AM EST to examine the regulatory and technical considerations in implementing QbD for coatings in modified-release formulations, including strategies to mitigate the risks associated with alcohol-induced dose-dumping and the application of alcohol-resistant coatings.

PharmTech Webcast: QbD in Solid Dosage

Patricia Van Arnum PharmTech editor Quality by Design (QbD) is changing drug development and manufacturing. The science- and risk-based approach inherent in a QbD paradigm increases process understanding and leads to better drug development and manufacturing. Sharing lessons learned and strategies for applying QbD in solid dosage development and manufacturing is valuable. Pharmaceutical Technology will address this topic in a webcast,A Pragmatic Application of QbD: Turning Theory into Tangible Success” this Thursday May 2 from 11:00 to 12:00 PM EST.

Two industry experts will share their experience with QbD and offer insight into how the practical application of QbD contributed to the success of their projects. Through several case studies, these experts will provide lessons learned and advice on the measures they took that enabled the success of their projects; steps that can be universally applied to other projects.

Don Barbieri, associate director of formulation and process development at Patheon, will present case studies demonstrating different aspects of the QbD approach, including identifying CQAs (critical quality attributes) and CPPs (critical process parameters) as well as how to perform risk assessment, incorporate risk mitigation into a process, and how to develop a design of experiments (DoE).

David Smith, pharmaceutical specialist, formulation and process development at Patheon, will present a case study where the pragmatic application of QbD enabled a successful technology transfer of a film-coated tablet from Phase III to commercial scale.

Concerns Raised Over the Comparability of Branded/Generic-Drugs

Stephanie Sutton Pharm Tech EuropeLast week, FDA deemed that a generic drug manufactured by Impax Laboratories and marketed by Teva Pharmaceuticals USA was not therapeutically equivalent to its reference product. The drug in question, Budeprion XL 300 mg, was approved in the US in December 2006 as a generic form of GlaxoSmithKline’s antidepressent drug, Wellbutrin XL 300 mg. Read more »

Sample questions:

• I have a BCS Class II compound for which amorphous solubility is easily sustained, but I can’t get the compound to rapidly dissolve. What are some solutions, particularly with respect to excipient selection?
• I have a compound that is non-ionizable and does not form a stable salt. Are co-crystals my best option and what are the key criteria in identifying a suitable co-crystal?
• I am having trouble maintaining product stability when scaling up a lyophilization process. What are the likely factors causing the problem?
