New Delivery Approaches


PEPTIDE ORAL DELIVERY 40 YEARS ON

Challenges of oral peptide delivery

• Low permeability across epithelial membranes

• Low bioavailability impact on cost and manufacturing scale

• Poor stability of peptide in standard oral formulations

Technology Solutions• Standard enteric coated tablet or capsule• Permeation enhancing excipients• Summary: BA << 5% vs SC injection


SCT ORAL FORMULATION PROGRAMTARSA THERAPEUTICS (ENTERIS / UNIGENE)

• Originally supported by Novartis to phase 3• Unigene and Novartis developed oral tablet

formulation• Bioavailability ~ 1% vs SC• Phase 3 study: 200 microgram• Phase 3 results published• FDA accepted for review Oct 2015• Initiated development 1990 or so• Citric acid, lauryl carnitine

MW 3431.85 g/mole

SEMAGLUTIDE FOR ORAL DELIVERYNOVO OPTIMIZED GLP-1 ANALOGUE

• Bioavailability ~ 0.25% vs SC injection• Phase 3 study doses: 3, 7,14 mg orally vs 0.5 mg SC• 2019 NDA submission likely• Standard permeation enhancing technologies (Emis SNAC)• Likely to experience food effect – may not be as important• Novo relying on ability to manufacture recombinant GLP-1 cost

effectively (North Carolina manufacturing plant)• Structure is similar to Liraglutide with some important changes


ORAL DELIVERY INNOVATIONDEVICE ENGINEERING APPROACH

• Greatest leap forward is from engineers• Microneedle as an approach for oral delivery

• Rani Therapeutics (dissolving microneedles)• Bob Langer and MIT group (metal microneedles)

• Risks• Technology risk – very early exploratory studies, limited PK data• No safety data – safety of regularly penetrating lumen of gut• Drug loading, device complexity, manufacturing complexity


RANI THERAPEUTICSDISSOLVING MICRONEEDLE APPROACH

www.ranitherapeutics.com

Rani Therapeutics comes from Mir Imran’s Incube Labs

• Solid microneedle (stability)• Enteric coated capsule• Bioavailability >50% vs SC• Microneedle and capsule

release mechanism are new• Large biologics possible• Long half-life opportunity• Phase 1 late 2018


MIT GROUPMETAL MICRONEEDLES

MIT Group:Bob Langer, Daniel Blankschtein, Daniel Anderson, Avraham Schroeder, Carlo Traverso, Baris Polat, Carl Schoellhammer

Ref: Traverso et al., JOURNAL OF PHARMACEUTICAL SCIENCES 104:362–367, 2015

• Microneedle is solid or hollow• Novo collaboration


ORAL BIOLOGICS DELIVERY SUMMARY

• Permeation enhancers are still primary approach• Bioavailability still quite limited (e.g. 2% sCT)• Risks well characterized• Formulations and manufacturing well understood

• Promise of devices for oral delivery• Gut penetration approach is significant• Risk profile still to be defined• New manufacturing systems needed


I am fortunate to work with a really strong team!

Thanks to our collaborators, clients, colleagues, friends, and advisors!


SEMAGLUTIDE STRUCTURAL DIFFERENCES TO LIRAGLUTIDE (ONCE DAILY GLP-1)

2. Fatty acid side chainoptimized for enhanced albumin binding affinity

3. Linker optimized move the albumin bound fraction (99%) away from albumin to enhance activity

1. C-terminus histidinechanged to AIBN for enhanced DPPIV stability
