Evidence of effectiveness

You will need to provide evidence of effective management of customer complaints with your application for certification. 

Regarding the effectiveness of the quality system, the very existence of a document is not evidence of effectiveness but it can be regarded as a record. To be a quality record, the document would need to contain results of an examination into the effectiveness of the system. 

Pyridoxine is used in morning sickness. Its mechanism of action remains unclear and several reviews of the use of pyridoxine have failed to find conclusive evidence of effectiveness. A recent double blind trial found pyridoxine to be of benefit in reducing nausea only. Some clinicians use pyridoxine as the first drug on the basis that it is the least likely to be toxic to the foetus. 

Thus, the AR directly protect DNA from the UV-damage. This is manifested in the saving of the total amount of this biopolymer, preventing its deep degradation due to formation of double-stranded breaks, as well as preventing the single -stranded breaks without transition of supercoiled into the relaxed circular form of DNA. Evidence of effects increased with length of the alkyl radical of the AR molecule and with AR concentration increase. 

There are four types of economic evaluation cost-minimization analysis, cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis. The analytic framework chosen will depend upon the economic questions posed and the clinical evidence of effectiveness for the interventions (Gold et al, 1996 Dmmmondetal, 1997). 

The liver is sensitive to hexachloroethane following both acute and longer term exposure scenarios. Evidence of effects on the liver include increased weight and centrilobular necrosis in rats and rabbits and increased serum levels of liver enzymes in sheep. There can also be fatty degeneration of the tissues and hemorrhage when damage is severe. 

Clarifies the requirements for NDA approval to say that data from one adequate and well-controlled study, together with confirmatory evidence, may, in the discretion of FDA, constitute substantial evidence of effectiveness of a new drug.

Another issue is how to interpret a clinical trial with equivocal results. While Schor and Karten established the probability of less than 1 in 20 P < 0.05) that a difference between two groups was due to chance as meaning that it was due to the drug, they did not establish criteria for how to properly interpret studies that failed to find this big a difference. Can this lack of evidence of effect be considered as evidence of lack of effect People have settled on the convention that a clinical trial must include enough patients to have at least an 80% chance of finding an effect if an effect really exists. Failure to find an effect in this large a trial is considered evidence of true lack of effect. This has been named the power of the study. How can we handle studies that do not have this power ...

Human studies are designed to determine Does the drug work To provide an answer, pharmaceutical companies, through a series of controlled clinical trials, must, according to the FDA, collect and submit substantial evidence of effectiveness, as well as confirmation of relative safety in terms of the risk-to-benefit ratio for the disease that is to be treated. It is critical from the outset to design clinical studies that pose the right question and provide an answer to the question in the intended patient population. 

In the final analysis, approval of a BLA or NDA comes down to two key questions Do the results of well-controlled studies provide substantial evidence of effectiveness and Do the results show the product to be safe under the conditions of use in the proposed labeling Safe, in this context, means that the benefits of the drug appear to outweigh its risks. On completion of the review, CDER or CBER sends a letter to the applicant sponsor stating that the drug is approved for marketing is approvable,... 

The decision cleared the way for the FDA in the 1970s to prevent the sale of ineffective drugs. Besides the drugs that Upjohn included in the suit, other marketed drugs without credible evidence of effectiveness could be, after review and notice, removed from the market. The public could then have more trust in the drugs prescribed and sold. Moreover, the decision... 

Examples of particularly important regulations include the 1970 regulations that defined what constitutes the "well-controlled investigations" needed to provide substantial evidence of effectiveness as required by the 1962 Amendments. 

Our customer or our customer s representatives are afforded the right to verify at the source or upon receipt that the purchased product conforms to the specified requirements. Product verification by the customer does not absolve our operation of the responsibility to provide a fully acceptable product, nor does it preclude subsequent rejection. When our customer carries out product verification at a vendor s plant, such verification is used as evidence of effective quality control of the vendor. 

Expanded controlled and uncontrolled clinical trials intended to gather additional evidence of effectiveness for specific indications and to better understand safety and drug-related adverse effects. Phase III trials are usually large multicenter trials which collect substantial safety experience and may also include specialized studies needed for labelling (e.g. paediatric or elderly, comparative agents). Thousands of patients may be included in the Phase III trials.

A systematic review of the literature aimed to assess the effectiveness of any type of complementary therapy for intermittent claudication revealed that there is no evidence of effectiveness of acupuncture, biofeedback therapy, chelation therapy, CO(2)-applications and the dietary supplements of Allium sativum (garlic), omega-3 fatty acids and Vitamin E (86). 

Is the drug effective The relative safety is balanced in a cost/benefit analysis Unless there is a demonstrable, clear benefit, no drug is sufficiently desirable to deserve approval. The FDA does not approve placebos whose only benefit is subconscious. Compelling evidence of effectiveness, ideally tied to sound theory, is required.
