Randomized Controlled Trial Multicenter Study
Ponsegromab for the Treatment of Cancer Cachexia.
Cachexia is a common complication of cancer and is associated with an increased risk of death. The level of growth differentiation factor 15 (GDF-15), a circulating cytokine, is elevated in cancer cachexia. In a small, open-label, phase 1b study involving patients with cancer cachexia, ponsegromab, a humanized monoclonal antibody inhibiting GDF-15, was associated with improved weight, appetite, and physical activity, along with suppressed serum GDF-15 levels. ⋯ Among patients with cancer cachexia and elevated GDF-15 levels, the inhibition of GDF-15 with ponsegromab resulted in increased weight gain and overall activity level and reduced cachexia symptoms, findings that confirmed the role of GDF-15 as a driver of cachexia.

Randomized Controlled Trial Multicenter Study
Levofloxacin for the Prevention of Multidrug-Resistant Tuberculosis in Vietnam.
Prevention of drug-resistant tuberculosis is a global health priority. However, trials evaluating the effectiveness of treating Mycobacterium tuberculosis infection among contacts of persons with drug-resistant tuberculosis are lacking. ⋯ Although the incidence of tuberculosis was lower in the levofloxacin group than in the placebo group at 30 months, the difference was not significant.
