Roche discontinued the Phase III CREAD 1 and CREAD 2 trials after an interim analysis found that crenezumab was unlikely to improve Clinical Dementia Rating-Sum of Boxes (CDR-SB)scores compared to placebo in patients with prodromal or mild Alzheimer's disease.

Pfizer and Lilly announced that in a 24-week, 849 patient, Phase III trial, patients treated with tanezumab 5 mg had a greater decrease in the WOMAC pain subscale and WOMAC Physical Function subscale with an improvement in the patient’s Global Assessment of OA compared to placebo in patients with osteoarthritis. The 2.5 mg dose of tanezumab had a greater decrease in the WOMAC pain subscale and WOMAC Physical Function subscale, but no improvement in the patient’s Global Assessment of OA compared to placebo. In a 698 patient, Phase III trial, rapidly progressive osteoarthritis (RPOA) was observed in 1.3% of tanezumab and in an 849 patient, Phase III trial, RPOA was seen in 2.1% of patients. RPOA did not develop with any patient that received placebo in either trial. The ratio of Type 1 RPOA (joint space narrowing) to Type 2 RPOA (bone loss and joint destruction) is 2:1 in both trials.
Takeda announced that in the 15-month phase 1 portion of the 20,000 patient, Phase III, TIDES trial, two doses of Takeda’s dengue vaccine (TAK-003) demonstrated efficacy in preventing dengue fever caused by all four virus serotypes healthy in children and adolescents ages four to 16 years living in dengue-endemic areas. Part 2 of the TIDES trial will evaluate the vaccine at 21 months and include the secondary endpoints of efficacy by serotype, baseline serostatus and severity. Part 2 data is expected to be available at the end of 2019. Part 3 Orf the trial will evaluate efficacy and long-term safety for an additional three years. The BLA submission will be based on Part 1 and Part 2 data.
Two Phase III studies, ENGAGE and EMERGE, were initiated in 2015 to evaluate the safety and efficacy of aducanumab in slowing cognitive impairment and progression of Alzheimer's disease (AD).

Biogen announced plans in early 2019 for a third Phase III trial that will evaluate aducanumab for the prevention or delay in the clinical onset of the disease.
In the 30-day, 632 patient, Phase III IMPACT 1 trial, cadazolid was non-inferior to vancomycin in reaching clinical cure (84% vs 85%) in patients with mild-to-moderate or severe C difficile infection. In the 30-day, 609 patient, Phase III IMPACT 2 trial, treatment with cadazolid did not reach non-inferiority to vancomycin in reaching clinical cure (81% vs 86%) in patients with mild-to-moderate or severe C difficile infection. Development of cadazolid was halted in 2018 after the failure of a Phase III trial.
