Exocrine Pancreatic Insufficiency

Brief summary

Phase 1a/1b single and multiple ascending dose study of oral CDX-7108 in healthy adult subjects and a single dose proof-of-concept study of oral CDX-7108 in subjects with exocrine pancreatic insufficiency. No clinical studies have yet been performed with CDX-7108 and its effects in humans are unknown. This is the first-in-human (FIH) study of CDX-7108, which aims to assess the safety, tolerability, pharmacokinetics (PK) of escalating single and multiple oral doses of CDX-7108 in healthy adult subjects and to evaluate the pharmacodynamics of a single dose of oral CDX-7108 in a proof-of-concept (POC) study in subjects with exocrine pancreatic insufficiency (EPI).

Detailed description

This is an integrated 3-part study to investigate the safety, tolerability, PK, and PD of CDX-7108. The Parts A and B are randomized, double-blind, placebo-controlled dose escalation parts to investigate the safety, tolerability, immunogenicity, and PK of CDX-7108 after single and multiple oral dose administration in healthy adult subjects. Part C is a randomized, double-blind, placebo-controlled, single-dose, 2-way crossover part to assess POC of CDX-7108 in terms of PD as well as its safety, tolerability, and immunogenicity in subjects with EPI. The study will commence with Part A (single ascending dose \[SAD\] study) and will progress to Part B (multiple ascending dose \[MAD\] study), and Part C (POC study)

Interventions

DRUGPart A

Randomized, double-blind, placebo-controlled dose escalation part to investigate the safety, tolerability, immunogenicity, and PK of CDX-7108 after single oral dose administration in healthy adult subjects. Single-dose administration of CDX-7108 at the following anticipated dose levels. 10 000, 50 000, 150 000, 250 000, and 500 000 lipase units will be evaluated in 5 sequential cohorts of 6 subjects each.

DRUGPart B

Randomized, double-blind, placebo-controlled dose escalation parts to investigate the safety, tolerability, immunogenicity, and PK of CDX-7108 after multiple oral dose administration in healthy adult subjects. It will evaluate multiple dose administration of CDX-7108 at an appropriate low (50 000 lipase units), mid (150 000 lipase units), and high dose (250 000 lipase units) 4 times a day (QID) for 6 consecutive days in 3 sequential cohorts of 6 subjects each.

DRUGPart C

Randomized, double-blind, placebo-controlled, single-dose, 2-way crossover part to assess POC of CDX-7108 in terms of PD as well as its safety, tolerability, and immunogenicity in subjects with EPI. Approximately 10 subjects with severe EPI from partial/total pancreatectomy or chronic pancreatitis will be enrolled. It is anticipated that Part C (POC study) will commence after completion of the third single-dose cohort from Part A (SAD study) and following SRC review of the data from this cohort.
