CMC Troubles? Send Us Your Questions

Pharmaceutical Technology and Patheon are partnering to provide you—our readers—with CMC advice from some of the leading formulation scientists and pharmaceutical manufacturing experts in the world. To get started, we need to know what plagues your CMC strategies and daily work. Email your questions directly to Editorial Director Angie Drakulich at (*Note: We will keep your name and company affiliation anonymous.)

Answers will be provided by the Patheon Certified Consultants team beginning in the January 2013 print and online editions of PharmTech. These experts have collectively brought more than 200 pharmaceutical products to market, including some of the world’s largest blockbusters.

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?

Odorous Taints Linked to Treated Wood Pallets

It is amazing what the human nose knows.  Well, those who originally detected a musty, moldy odor in pharmaceutical and healthcare products didn’t know where it came from.  But the odorous taints that resulted in product recalls were found to come from tribromoanisole (TBA) and trichloroanisole (TCA), and have been linked to treated wooden pallets from sources outside the US, the Parenteral Drug Association (PDA) reported in a September PharmTech article, which summarizes the findings of the recent PDA Technical Report No. 55 on detecting and mitigating taints and odors from TBA and TCA.

USP Updates Heparin Sodium Monograph

In 2008, adverse affects and deaths linked to Baxter’s blood thinner drug heparin revealed contamination in the heparin supply chain originating from an API manufacturer in China. FDA identified oversulfated chondroitin sulfate (OSCS) in the contaminated heparin. In response to the 2008 heparin situation, the United States Pharmacopeia Convention (USP) has revised the quality standards for heparin. Anita Szajek, PhD, and Tina Morris of USP highlight USP’s revisions to the heparin sodium monograph in the September 2012 issue of PharmTech.

Pharmaceutical-Based Cargo Security and Theft Prevention

Cargo theft, for many years, was a problem that largely plagued the electronics industry, but criminals have recently shifted more attention to the far more lucrative pharmaceutical trade. In March 2010, thieves masterminded a heist of $75 million worth of cancer, psychiatric and blood-thinning drugs from a Connecticut warehouse by cutting a hole in the ceiling and dismantling alarms during a severe storm that masked their activities from the local authorities. To curb future cargo theft, it is imperative that pharmaceutical companies develop solid, globally applicable conveyance security programs.

PharmTech Biomanufacturing Partnership Conference: The Rising Bar in Outsourcing

Patricia Van Arnum PharmTech editorWhat will be the future of pharmaceutical outsourcing? What factors will influence the relationships between sponsor companies and contract service providers and what practical solutions are both seeking? These questions were addressed at a conference this week in Philadelphia, Bio/Pharmaceutical Manufacturing Partnerships, organized by CBI in conjunction with Pharmaceutical Technology. Read more »

FDA Spectral Library and Border Patrol Work Under Way

Angie DrakulichFDA’s Lucinda Buhse has been spearheading the agency’s spectral library of excipients as a means to improving supply chain security of the pharma industry, particularly focused on raw materials entering US borders (there are 300 entry points in total). She and Philip Merrill of IPEC wrote about the library last summer in PharmTech and Bushe gave an update on the program at the IPEC ExcipientFest Americas conference in late April 2012..

Hand-held instruments containing the libraries are being used at the borders to rapidly verify and authenticate materials via XRF, IMS, Raman, and NIR screening methods. Materials in question are then investigated at local FDA laboratories.

FDA has been collecting samples from the industry to add to the library but only has about 20% of its most wanted materials (see Table I in the July 2011 PharmTech article) thus far. Incoming materials must match a Hit Quality Index of 0.95. Bushe pointed out that the supplier or site of material used for the library has not had a significant or statistical impact on the library index to date. Samples are therefore being collected from various industry players and from various sites.

Looking ahead, FDA aims to fill its library with all the excipient samples it’s seeking and will work to finalize its classification and modeling strategies.
