Chlorin E6 (CE6) is a second-generation photosensitizer with antitumor activity when used in combination with irradiation. In a mouse model of implanted fibrosarcoma, Chlorin E6 (2.5-10 mg/kg, i.v., 50-200 J/cm2 irradiation) resulted in complete tumor disappearance after varying degrees of irradiation. Agents including Chlorin E6 were tested in a Phase I clinical study in patients with early superficial squamous cell carcinoma of bronchial origin with favorable results (40 mg/m2, IV, 100 J/cm2 laser irradiation). In a Phase II clinical trial in patients with early stage lung cancer, the same mode of administration resulted in a complete response in 82.9% of patients. Chlorin E6 has been investigated as a nanotechnology drug delivery tool.

Bavisant dihydrochloride hydrate (JNJ31001074AAC) is a highly selective, orally active antagonist of the human H3 receptor with a novel mechanism of action related to wakefulness and cognition, and it has potential as a treatment for ADHD. In a clinical trial, the mean change from baseline in the total ADHD-RS-IV score at day 42 was -8.8 in the placebo group versus -9.3, -11.2, and -12.2 in the bavisant 1 mg/day, 3 mg/day, and 10 mg/day groups, respectively; however, the change in the 10 mg/day group was not statistically superior to placebo (p=0.161). Statistical comparisons of the 1 mg/day and 3 mg/day groups with placebo based on a step-down closed testing procedure were not performed. Bavisant has completed a phase II ADHD trial, but no results have been reported [1].
