Conditional approval

The developer may receive conditional approval for up to five years, through annual renewals, on the basis that the safety has been established, but that complete efficacy data will only be generated during the conditional approval period. The labelling must bear the statement conditionally approved by FDA pending a full demonstration of effectiveness under application number . 

In certain cases, such as the treatment of zoo animals or endangered species, it may be impossible to recover the cost of approval of a drug for that species. In such circumstances, the FDA can add the drug to an index oflegally marketed non-approved drugs. A drug can only be indexed for use in situations vhere there is no risk of it entering the human food chain. 

A developer may apply to have a new drug designated. Designation entitles the developers to avail themselves of the same type of incentives in terms of supports and market exclusivity that apply to human orphan products.

Occasionally, an otherwise good candidate toller may need to be rejected or conditionally approved until assurance can be made that contamination, improper storage facilities, confidentiality and other issues are properly managed. 

SEC. 571. CONDITIONAL APPROVAL OF NEW ANIMAL DRUGS FOR MINOR USE AND MINOR SPECIES. 

Special Condition Requests (conditional approval, accelerated review, additional year data exclusivity)... 

In 1992, the FDA issued a moratorium on silicone-gel-filled implants, and restricted their use to reconstmction and clinical smdies. In 2000, they approved saline-filled implants. In 2003, the General and Plastic Surgery Devices (GPSD) Advisory Panel recommended reapproval of gel-filled implants, but the FDA decided to wait for more clinical evidence of safety. In late 2005, the Panel recommended conditional approval of Mentor s and Inamed s gel implants. In October 2006, Health Canada approved the use of sUicone-gel-filled implants, with a warning that no medical device is 100% safe. ... 

Regulatory status In 1998, Lopez Canyon Sanitary Landfill received conditional approval for an ET cover, which required a minimum of 2 years of field performance data to validate the model used for the design. An analysis was conducted and provided the basis for final regulatory approval of the ET cover. The cover was fully approved in October 2002 by the California Regional Water Quality Control Board—Los Angeles Region. 

In 1985, 1080 use was conditionally permitted in livestock protection collars and in single lethal dose baits a registration for the livestock protection collar was issued to the U.S. Department of the Interior on July 18, 1985 (USEPA 1985). On Lebruary 21, 1989, the registration for 1080 was canceled, effectively prohibiting all uses. In June 1989, however, technical 1080 was conditionally approved for use only in the 1080 livestock protection collar. The 30-mL collar is registered for use by the U.S. Department of Agriculture by the states of Montana, Wyoming, South Dakota, and New Mexico and by Rancher s Supply, Alpine, Texas (Palmateer 1989, 1990). 

At the NDA stage, make more use of the NDA s current conditional approval mechanisms, so that in a wider range of circumstances (including at the request of a sponsor) a drug may be approved for the market for limited indications, considerably earlier than it would be at present, on condition that the development programme continues and that the conditions of initial approval are enforced. In this way, the law s ultimate effectiveness and safety standards for a full approval are safeguarded, not compromised. 

The conditional approval step could be integrated with the existing system of market-place utilisation controls, and thus be used as an option to expedite approvals for earlier access to promising therapies. However, it would be important not to burden new drugs unnecessarily with conditional approval status if there is not a real reason to do so. 

The postclosure survey report should fully and completely document all activities and all results (data), and it should certify that the closure has been done in compliance with the work plan and all applicable laws and regulations. A professional engineer licensed in the state where the closure was done must attest to the report. (In the case of JACADS, the state is California, where the EPA Region IX office is located.) Appendix E provides two sample tables of contents from industrial RCRA closure survey reports accepted by EPA they can be used as a guide to the contents of the final and interim reports required. Box E-1 shows the table of contents for a final facility RFI postclosure report. Box E-2 shows the table of contents for an interim remedial measures report, used to obtain EPA conditional approval for the cleanup of specific areas prior to final facility closeout. 

In January 2006, the FDA approved Sunitinib for the treatment of GIST and RCC, and it tvas launched in the USA later that month, hi April 2006, the European committee for medical products for human use (CHMP) recommended approval of Sunitinib for second-Une RCC and for GIST, and conditional approval in both indications was granted in July 2006. In May 2006, the drug was approved by Health Canada for the treatment of GIST. 

The regulatory framework is forever changing and undoubtedly our statistical methodology will itself change to meet these new requirements. A new CHMP statistics guideline is planned, for example, in relation to conditional approval while the FDA are considering more therapeutic-specific recommendations in relation to the choice of the non-inferiority margin. 

Testing is to be conducted by designated test personnel. Each test result must be recorded (normally handwritten and initialed) by the person who conducted the test and similarly verified by a second person designated to check that the procedure has been carried out and the results are complete. Test results must be formally evaluated against the predefined acceptance criteria and the conclusions (e.g., unconditional pass or fail) recorded complete with an explanatory comment by a designated validation team member (normally the second test person). In instances in which a conditional pass conclusion is justified, this must be formally reviewed and rigorous controls imposed on the pass conditions. Approval and sign-off of the completed test records is normally the responsibility of the quality department representative on the validation team.

Whereas Phase 1, 2, and 3 studies are conducted prospectively using subjects or patients whose entrance into the study depends on strict inclusion and exclusion criteria. Phase 4 studies employ mainly observational, rather than exclusionary, study designs. Postmarketing surveillance and any additional studies requested by the regulatory agency as conditional approval of the NDA are conducted during Phase 4. 

Stability testing will be guided mainly by the conditions approved in the IND. However, the manner in which the stability program is managed should be similar to that required for commercial products. For example (not an all inclusive list) ... 

Dipyridamole is also a potent coronary arteriolar vasodilator, perhaps by opening of vascular K tp channels (2). However, the Food and Drug Administration withdrew conditional approval for certain drug products containing dipyridamole, because of a lack of sufficient evidence of effectiveness in the long-term therapy of angina pectoris (3).

Expedited reviews The new Regulation foresees the possibility of an expedited procedure of only 150 days duration, for products of major interest for public health, which are addressing an unmet medical need. Also, a conditional approval may be granted, which would be reviewed yearly.

As with other new technologies, it is possible that the first licensed DNA vaccines will receive conditional approval. In this case, postlicensing Phase IV clinical trials may be requested to address and monitor remaining unresolved issues by specific studies or on a larger scale. Furthermore, as for any medicinal product, effective and intensive pharmacovigilance procedures will be used to closely monitor the appearance of any side effects, while the vaccine is applied widely and routinely.
