Takeda reports promising findings from study of norovirus vaccine candidate

Takeda Pharmaceutical (Takeda) has reported that results from a Phase I/II clinical study of its intramuscular bivalent (GI/GII) norovirus vaccine candidate showed that the vaccination has resulted in a reduction of symptoms, caused by experimental exposure to the most common strain of norovirus, genotype GII.4.

Ninety eight healthy adults were challenged with the most commonly occurring norovirus (genotype GII.4), which causes gastroenteritis, were part of the Phase I/II randomised, double blind, placebo-controlled multicentre study.

The Phase I/II clinical study showed that two doses of the experimental bivalent norovirus were well tolerated, and that the candidate vaccine had a clinically relevant impact on the incidence of norovirus illness after challenge and also the severity in breakthrough cases.

Pfizer has reported top-line results from two Phase IIIb, placebo-controlled trials with Lyrica (pregabalin) capsules CV in patients with fibromyalgia (FM) and painful diabetic peripheral neuropathy (DPN) respectively.

In addition to meeting the primary endpoint, the multicentre, double-blind, randomised, placebo-controlled, two-way cross-over study of Lyrica showed reduction in fibromyalgia pain in patients who were treated concurrently with antidepressant therapy for co-morbid depression.

The company said the painful DPN study did not meet its co-primary endpoints by reducing DPN pain and DPN pain on walking, compared with placebo.
