The following invention is directed to macromolecules having controlled stoichiometry and topology, processes for their production, and applications for their use. The macromolecules have a controlled functional moiety stoichiometry and include at least one dendritic motif having a surface layer formed from at least one surface building unit and at least one subsurface layer formed from at least one building unit, the surface building unit and building units having a hydrocarbon backbone bearing a carbonyl group and at least one amine group; and at least two different functional moieties on the building unit and/or surface building unit; where functional moiety stoichiometry refers to the number and type of functional moieties.

The present invention relates to a macromolecule comprising a dendrimer having surface amino groups to which at least two different terminal groups are attached including a pharmaceutically active agent and a pharmacokinetic modifying agent, the pharmaceutically active agent comprising a hydroxyl group and being attached to the surface amino group of the dendrimer through a diacid linker. Pharmaceutical compositions comprising the macromolecules and methods of treatment using the macromolecules are also described.

Methods of treatment or prophylaxis of bacterial vaginosis, prevention of recurrence of bacterial vaginosis and alleviation or prevention of symptoms or diagnostic criteria of bacterial vaginosis are provided. The methods include administration of an effective amount of a macromolecule comprising a polylysine, polyamidoamine, poly(etherhydroxyamine) or poly(propyleneimine) dendrimer and one or more sulfonic acid containing moieties attached thereto.

OBJECTIVES:: To evaluate safety, tolerability and systemic pharmacokinetics of escalating doses of SPL7013 Gel in healthy women. DESIGN:: Randomized, double-blind, placebo-controlled dose-escalation trial. Methods: Thirty-seven healthy women were randomized to receive 3.5 g of 0.5% (N = 8), 1% (N = 8), or 3% (N = 9) SPL7013 Gel or placebo gel (N = 12), applied vaginally once daily for 7 consecutive days. Genital toxicity was determined by interview, physical examination, assessment of vaginal microflora and colposcopy. Systemic toxicity was determined by nongenital adverse events (AEs) and laboratory assessments. Plasma was collected for pharmacokinetic analysis. Results: Genital AEs considered potentially product-related were all mild and reported by 5 (20%) women receiving SPL7013 Gel and 2 (17%) women receiving placebo gel. The most common were abdominal pain or discomfort, with no reports of vaginal burning or malodour, or genital-tract pain. There were no clinically significant colposcopic findings, including of genital inflammation or epithelial disruption. Lower concentrations of normal lactobacillary flora occurred during SPL7013 Gel and placebo gel use, with a decrease in anaerobes in the SPL7013 Gel groups. There were no reported cases of bacterial vaginosis, and lactobacilli returned to predose levels in most women after treatment. All nongenital AEs were of mild or moderate severity, expect for a severe tension headache in a woman receiving placebo. There was no absorption of SPL7013 into the systemic circulation. Conclusions: SPL7013 Gel applied vaginally once daily for 7 days at concentrations of 0.5% to 3% was safe and well tolerated in healthy, sexually abstinent women, with no evidence of systemic toxicity or absorption. © Copyright 2010 American Sexually Transmitted Diseases Association.
