A proof of principle investigation of a novel enzyme formulation on dental calculus deposition: a 4-week randomized human clinical trial.

Background: The dissolution of dental calculus, safely and at home, is among the more challenging issues facing the over-the-counter healthcare industry. Pontis Biologics, Inc. has developed novel model of calculus development and structure and has formulated a dentifrice (Tartarase™) using digestive enzymes as active ingredients that is shown to dissolve dental calculus in this Proof of Principle clinical trial.

BCMA-CD19 compound CAR T cells for systemic lupus erythematosus: a phase 1 open-label clinical trial.

Objectives: This study aims to evaluate the safety and efficacy of BCMA-CD19 compound chimeric antigen receptor T cells (cCAR) to dual reset the humoral and B cell immune system in patients with systemic lupus erythematosus (SLE) with lupus nephritis (LN).

Methods: This is a single-arm open-label multicentre phase 1 study of BCMA and CD19-directed cCAR in patients suffering from SLE/LN with autoantibodies produced by B cells and plasma/long-lived plasma cells. In this clinical trial, we sequentially assigned biopsy-confirmed (classes III-V) LN patients to receive 3×10 cCAR cells/kg postcessation of all SLE medications and conditioning.

The effect of bupropion sustained-release on cigarette craving after smoking cessation.

Background: Most (>50%) smokers who attempt to stop smoking relapse within the first year of abstinence. The effect of continued use of pharmacotherapy for smoking cessation on relapse rates is unknown. Bupropion sustained-release (SR) is the first non-nicotine-based therapy that is effective for achieving abstinence from smoking.
