Dinical trial

The process of conducting dinical trials for drug approval may be broken down into three consecutive phases of ...

Jones and Pickard 1980). Titanium tetra-fluoride, when used in a dinical trial, prevented caries to a greater extent than did acidulated phosphate fluoride (Clarkson and Wefel 1978, Mundorff et al. 1972, Reed and Bibby 1976, Shrestha et al. 1972, Wei et al. 1976). Porous-surfaced titanium alloy dental implant systems were also tested and used in animals and man (Deporter et al. 1986a,b). 

Concurrent validation might be appropriate in situations where a single or limited number of API batches are produced for dinical trials. This involves obtaining data from extensive in-process and end testing to demonstrate that the instant process run yields an API meeting established specifications and quality characteristics. Process validation should be completed once additional batches are produced under replicated conditions. 

Prospective validation should be used when multiple batches are initially produced for dinical trials, even when such batches are produced on a pilot scale or small scale. Once pilot- or small-scale... 

The citrate salt of isoaminile [77-51-0] (50) is a nitrile used as an antitussive in numerous European countries. In dinical trials it was shown to be as effective as codeine or chlophedianol, with few mild side effects. Isoaminile citrate is longer acting than chlophedianol and does not cause the respiratory depression of codeine (68). 

The final step in drug development inevitably involves dinical trials, with all their associated expense, logistical difficulties, risk and ethical problems. It is to be hoped that the power-fid tools that are now at our disposal will result in a new generation of safer and more effective treatments in the near future.

A major drawback of nanopartides formulated using cationic polymers that has limited thdr progress toward use in dinical trials is toxidty. Although the molecular basis of toxidty is undear, the polycationic nature of the polymers appears to be the main origin of toxidty. Thus, recent efforts to devdop polymers with reduced toxidty have focused on low-MW polymers, biodegradable polymers, and polymers with reduced cationic charge density. 

Very few hirman clinical trials have been conducted using polymer-nudeic add therapeutics. Table 1 lists the trials that have been published in this area. Each of these dinical trials will now be described in limited detail. 

In summary, there are very few polymer-nuddc add therapeutics that have been investigated in dinical trials. At this time (end of 2009), only two remain in progress (one is a localized administration (PEI DTA-H19 plasmid ) while the other is a systemic administration (CALAA-01 )). As more dinical data are accumulated, the designs of the polymer... 

Section 13.4 adds perspective to the experimental results obtained so far with these CXCR3 antagonists in disease models and in dinical trials. As such, it provides a useful overview of how synthetic antagonists have helped umaveling the therapeutic potential of CXCR3.
