Quality-by-design or “enhanced” approaches to drug manufacturing offer several benefits to industry, including better process understanding and better understanding of the interrelationship of material attributes and process parameters. This knowledge can lead to fewer nonconformances and less rejection and rework, according to several International Conference on Harmonization (ICH) Q11 expert working group members. (Q11 is the pending guideline on drug substance and manufacture.) Such an approach can also bring flexibility, whether it be regulatory flexibility or manufacturing flexibility. PharmTech asked the FDA members of the ICH Q11 working group about this issue and what industry should focus on and expect when applying a QbD approach. Read more »

Targeting a drug for small subgroups of patients is a new way to find effective therapies. This is often called personalized medicine, and it’s one of today’s most promising areas of new drug development. Last year, FDA approved two important targeted medicines: Xalkori (crizotinib), a lung cancer drug that targets tumors with the abnormal ALK gene, and Zelboraf (vemurafenib), a drug to treat malignant melanomas that have a certain gene mutation. Both drugs were approved with companion diagnostic tests to identify if patients have a susceptible tumor.

Today, the FDA approved Kalydeco (ivacaftor) to treat a specific subgroup of patients with cystic fibrosis (CF). Cystic fibrosis is an inherited genetic disease that affects a person’s lungs and other organs and may lead to an early death. What makes the availability of Kalydeco even more unique is that the drug’s developer, Vertex Pharmaceuticals, teamed up with the Cystic Fibrosis Foundation to develop and study the drug.

FDA issued last week its recommendations for three user-fee programs: the fifth authorization of the Prescription Drug User Fee Act (PDUFA) and new user-fee programs for human generic drugs and biosimilar biological products. The recommendations were transmitted to Congress, which will evaluate the recommendations. Read more »

Right now, many of us are thinking of how we could improve ourselves during the new year. Others, such as Ranbaxy, will be forced to improve themselves in 2012. The company signed a consent decree last week, and its management must be eager to put its ugly past behind it. Read more »

Drug shortages are increasing at an alarming rate. Between 2005 and 2010, the number of drug shortages per year leapt from 61 to 178. This year’s total, 220 as of October, already surpasses that of last year. Fortunately, FDA has taken a step that is intended to prevent drug shortages from becoming crises. Read more »

Just when it seemed that controversy over the Plan B contraceptive was a thing of the past, the drug returned to the headlines. In an unprecedented action, Health and Human Services Secretary Kathleen Sebelius overruled FDA’s decision to allow Teva’s Plan B One-Step to be sold over the counter to girls under the age of 17. In a public statement, Sebelius said that about 10% of girls can bear children by 11.1 years of age. Teva’s “label comprehension and actual use studies did not contain data for all ages for which this product would be available for use,” she said. But FDA sees the matter differently. Read more »

The day of reckoning is here. As patent protection expires for top-selling drugs, some firms are scrambling to stay one step ahead of generic-drug competitors. As Amy Ritter wrote last week, Pfizer is drawing scrutiny by asking pharmacy benefit managers to block pharmacies from filling prescriptions with generic alternatives to Lipitor, in exchange for a discount on the product. Rep. John Sarbanes (D-MD) asked the Federal Trade Commission to take action against this arrangement, but another tactic is also causing concern. Read more »

Economically motivated adulteration became a major concern after heparin manufactured by Baxter Healthcare was contaminated with oversulfated chondroitin sulfate. FDA told the Government Accountability Office (GAO) that getting information from industry about potential instances of economic adulteration is crucial to addressing the problem. Companies have been reluctant to share this information, but a GAO report suggests a possible solution. Read more »

When only a handful of manufacturers supply a given drug, production problems at any of those companies can lead to a shortage. Earlier this year, problems at Ben Venue’s Bedford, Ohio, site contributed to shortages of the cancer drug Doxil. The shortages are likely to continue now that Ben Venue has suspended manufacturing at the plant. Read more »

FDA Commissioner Margaret Hamburg held a special press briefing this morning on Genentech’s Avastin drug and its indications for metastatic breast cancer. She announced that the agency is revoking that indication based on FDA follow-up studies which did not show promising results. Read more »
