New drug combination shows promise as effective, safe treatment for rheumatoid arthritis

A new drug combination for rheumatoid arthritis treats the disease just as well as other intensive treatment strategies but with less medication and fewer side effects at a significantly lower cost. Doctoral researcher Diederik De Cock (KU Leuven) describes the strategy in a new study published in Annals of Rheumatic Diseases.

Rheumatoid arthritis (RA) is a chronic auto-immune disease that causes pain and stiffness in the joints, fatigue, bone damage and, eventually, loss of mobility. RA afflicts around 1% of people in the western world; in Belgium, 80,000 to 100,000 people currently live with the disease.

Because there is no known cure for RA, physicians focus treatment on suppressing disease activity. Therapies have improved in recent years, and clinical studies show that intensive treatment of early RA can prevent joint damage and improve patients' quality of life.

In the two-year study, called 'CareRA' (Care in early RA), researchers and clinicians in the rheumatology unit at University Hospitals Leuven examined various therapies for early RA. Their goal: to find the optimal combination and dosage of three commonly prescribed antirheumatic drugs (methotrexate, sulfasalazine and leflunomide) in combination with glucocorticoids (a class of steroid hormones).

The researchers divided 290 early RA patients into three treatment groups. Each group received a different combination therapy: 'COBRA Classic' (methotrexate, sulfasalazine and a high first dose of glucocorticoids), 'COBRA Slim' (methotrexate and a moderate dose of glucocorticoids) or 'COBRA Avant-Garde' (methotrexate, leflunomide and a moderate dose of glucocorticoids).

Sulindac drug can protect against oxidative damage due to AMD

In continuation of my update on Sulindac

Scientists at Florida Atlantic University's Charles E. Schmidt College of Science, as well as the Charles E. Schmidt College of Medicine, have found that sulindac, a known anti-inflammatory drug, can protect against oxidative damage due to age-related macular degeneration (AMD), one of the primary causes of vision loss in the elderly. Their findings were released today in an article titled "Pharmacological protection of retinal pigmented epithelial cells by sulindac involves PPAR-α" in the prestigious Proceedings of the National Academy of Sciences.

New treatment regimen for hepatitis C in transplant patients produces promising results


The investigational three-drug regimen, which produced hepatitis C cure rates of 97 percent, is an oral interferon-free therapy. Previously, the typical treatment for hepatitis C after a liver transplant was an interferon-based therapy, usually given for 48 weeks. It had a much lower response rate, had a risk of organ rejection and was poorly tolerated because of the immunosuppressants required to prevent rejection. The new oral regimen -- ABT-450, ombitasvir and dasabuvir (with or without ribavirin) -- produces significantly fewer side effects and is prescribed for 24 weeks.

Eribulin drug has minor added benefit in one patient group, indication of lesser benefit in others

In continuation of my update on Eribulin

Eribulin (trade name: Halaven) is approved for women with locally advanced or metastatic breast cancer in whom the disease has progressed despite prior drug therapy. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether the drug offers an added benefit over the appropriate comparator therapy in these patient groups.

According to the findings, there are both positive and negative effects. There is proof of minor added benefit for one group of patients. For other groups, there are hints or indications of lesser benefit.

Second assessment of eribulin
IQWiG already presented a dossier assessment of eribulin in February 2012. The subsequent decision on the added benefit made by the Federal Joint Committee (G-BA) was limited until April 2014. In addition, the drug manufacturer meanwhile obtained approval for an expanded therapeutic indication: In March 2011 eribulin was only available for patients who have progressed further after at least two chemotherapeutic regimens. Since June 2014, however, the drug can already be used after one unsuccessful treatment attempt. Hence there were two reasons ─ independent from each other ─ for the reassessment of eribulin.

G-BA specified appropriate comparator therapies
When the G-BA specified the appropriate comparator therapy, it distinguished between several treatment situations: The first one refers to patients who are not eligible for further chemotherapy with a taxane or an anthracycline. In this situation, eribulin was to be compared with individual chemotherapy containing the drugs capecitabine or vinorelbine.
In patients for whom taxanes or anthracyclines are principally still an option, eribulin was to be compared with an individual chemotherapy containing a taxane or an anthracycline.
