This glossary will help you understand words and phrases frequently used on ClinicalTrials.gov. An adaptive design clinical trial (also called adaptive randomization) is any design that allows adaptations to a clinical trial as it progresses.This type of trial is strongly recommended by the FDA for several reasons, including that it increases the odds a patient will receive a beneficial drug. ptPT�p@I���X�������I�.SB��82�z�^�>ͷ)�c^�2ǒ8n����ƺҔ$����:�M��O�h\+��GW��%*CzI������~�n��=2z ^KNlEd�,�D*TC�ov ��u�n��_WtɄP�]ܲ�՚JA:��!c櫇��[��o���>>�SA����K]6�z\m�Z~C�;Ji���Q�㷋[�g;X,�.�r|�e|�ou�,D�;��� It also assists with preparing application summaries or assessing evidence of efficacy and safety, principally from clinical trials in later phases of development.. �j5��"4�0���E�RS�\�i��y>�������o`�1�ڟe@`��[�����ޝ�p,*E%���Hu�PI�?S�4��L�eM._�7���_���=�T�^�_ON����9n���4�K!�(�d��eV��$����@�:�0�5�6�C��P�C5���}r$�"S$Ԣ!2�)�WD������#�j��-G��heX4����@::��4m-����}�/Ӌ���d���A�@��3ts�wR���@r+���;�`��F!

Every time you perform a statistical significance test, you run a chance of being fooled by random fluctuations into thinking that some real effect is present in your data when, in fact, none exists. For the purposes of registration, a clinical trial is any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes. 0000036921 00000 n The instantaneous hazard rate is the limit of the number of events per unit time divided by the number at risk, as the time interval approaches 0. For investigator-initiated clinical trials, follow NIAID’s required process as described at Investigator-Initiated Clinical Trial Resources.
