Preclinical data on toxicokinetics, pharmacokinetics, and pharmacodynamics from appropriate animal species are necessary for drug candidate selection and model building to determine the first time in human starting dose and clinical study design. This chapter discusses the selection of animal models with ...
aDuring the preclinical phase of drug development, Medical Affairs provides valuable perspective based on its understanding of alternative products and unmet medical needs. This insight can help produce a drug that addresses limitations in the current standard of care. 在preclinical阶段药物发展期间,医疗...
aDrug development begins with a preclinical phase. (See Figure 5.5) This testing takes place in the laboratory and builds a base of evidence in models that are progressively more similar to humans. Before a drug can be administered to humans, safety concerns dictate that it be tested in anima...

to drug candidate failure during clinical phase testing.” Page 1 of 8 Drug Discovery 1 Introduction Many drugs entering clinical trials still fail in late stage development due to unexpected drug toxicities (~22%), lack of biological activity (~31%), or poor pharmaceutical properties (~41%)....
Close interaction with the FDA, including a meeting to prepare for submission of an Investigational New Drug application, is critical to ensure that the preclinical development package properly supports the planned phase I clinical trial. 展开
The clinical-stage drug BTZ-043 accumulates in murine tuberculosis lesions and efficiently acts against Mycobacterium tuberculosis Therapy of tuberculosis is challenging, mainly due to complex structures of necrotic granulomas that often impair drug delivery. In this work, the authors show that the dru...
In a phase 1 dose-escalation trial of olpasiran (ClinicalTrials.gov: NCT03626662), the primary outcome was safety and tolerability, and the secondary outcomes were the change in Lp(a) concentrations and olpasiran pharmacokinetic parameters. Participants tolerated single doses of olpasiran well and...
Many promising drugs emerged in preclinical models and small phase 2 trials, but with a few exceptions, they fail to meet the primary endpoints in larger adequately powered phase 3 trials. Which new drugs will prove valuable remains uncertain. Improving clinical outcomes, delaying or preventing HF...
Close interaction with the FDA, including a meeting to prepare for submission of an Investigational New Drug application, is critical to ensure that the preclinical development package properly supports the planned phase I clinical trial.Introduction The drug development process is typically divided into...
