DrugDrug developmentdevelopment pathwaypathway Phase III Phase I 250-4000 more varied patient groups 20-50 healthy volunteers to – to determine short-term safety and gather preliminary data efficacy Animal Phase II experiments for ADME-TOX 150-350 subjects Phase IV studies, with disease – to carcinogenicity, determine safety Post-approval mutagenicity / and dosage studies to teratogenicity recommendations determine specific safety issues Preclinical Phase IV : Post development Phase I Phase II Phase III marketing surveillance Single drug : USD 1.2 billion investment !!!

Mainly funded by B&M Gates Foundation, Govts of USA, UK and the Netherlands. TacklingTackling AntibioticAntibiotic ResistanceResistance :: RISHIRISHI ChembiotekChembiotek ClininventClininvent DrugDrug DiscoveryDiscovery InitiativeInitiative z Application of genomics technologies to develop new antimicrobial compounds against essential proteins in bacteria. z Targeting 6 essential enzymes involved in bacterial cell wall synthesis. z Novel way of tackling multi-drug resistant bacterial infections since it will be extremely difficult for bacteria to develop resistance to critical house-keeping proteins. PromotingPromoting moremore clinicalclinical trialstrials inin thethe SEARSEAR The SEAR countries are conducive for clinical trials… z Low cost for clinical trial implementation. z Genetically diverse population. z Faster regulatory approvals. z Presence of pharmaceutical know-how and well trained technical personnel. z High quality clinical trial set-up. z More clinical trials translates into more opportunities for manufacture of generic drugs. PromotingPromoting ManufactureManufacture andand UptakeUptake ofof GenericGeneric DrugsDrugs An important way of reducing cost and increasing access to life-saving drugs. z Generic versions of drugs are 30-80% cheaper than the branded product. z Generic versions can be manufactured legally when the drug is off-patent. z Generic versions can be produced as “approved generics” with license from the manufacturer of the parent drug. z Generic versions can be legally manufactured in countries that take part in clinical trials of the original drug.
