Lennham Pharmaceuticals Announces Topline Results from Pharmacokinetic Study of d9-Caffeine Versus Caffeine

June 7, 2021 Off By BusinessWire
  • d9-Caffeine exhibited a similar Tmax, higher Cmax and a 4-fold higher AUC than caffeine
  • Exposure to the major metabolites of caffeine were substantially lower with d9-caffeine
  • Data supports potential use of d9-caffeine as a food & beverage ingredient and pharmaceutical product
  • Protected by two issued U.S. patents and multiple pending patent applications

CONCORD, Mass.–(BUSINESS WIRE)–Lennham Pharmaceuticals today announced topline results of the first ever human study of d9-caffeine. The study was conducted to compare the single-dose pharmacokinetics of caffeine versus d9-caffeine and their corresponding metabolites in healthy adult volunteers.

“Caffeine is a ubiquitously consumed product with many benefits, but is limited by a short half-life and Cmax and metabolite-related side effects,” said Bradford C. Sippy, Founder and CEO of Lennham. “d9-Caffeine potentially addresses these limitations, while retaining the beneficial properties of caffeine. We believe that d9-caffeine has significant potential as a food or energy drink ingredient at low doses, and as a pharmaceutical product at higher doses. We intend to rapidly advance our differentiated version of caffeine for food ingredient, energy drink, and pharmaceutical applications.”

The study was a randomized, controlled, double-blind, two-part, two-period crossover design. Unlabeled caffeine or d9-caffeine at two dose levels were administered with blood samples collected before and up to 48 hours after administration. Plasma levels for caffeine, d9-caffeine and their respective primary metabolites were analyzed.

d9-Caffeine exhibited a similar time to maximum plasma concentration (Tmax), a higher peak plasma concentration (Cmax) and a 4-fold higher total exposure (AUC) than a similar dose of caffeine. The three active metabolites of d9-caffeine demonstrated a lower Cmax and lower exposure relative to their un-deuterated counterparts. Results were consistent in the low and high dose comparison. Slower metabolizers of caffeine demonstrated a lower relative increase in exposure to d9-caffeine than rapid metabolizers. Both products were well tolerated. No adverse events for insomnia were reported during the study.

Lennham plans to present the results of this study at the International Society of Sports Nutrition’s annual meeting in St. Petersburg, FL on June 11, 2021 and to submit the results of the study for publication in a peer-reviewed scientific journal.

Lennham holds two broad United States patents on d9-caffeine as a food ingredient, U.S. Patent Nos. 10,582,716 and 10,765,130, which expire in 2039, and multiple pending applications.

About Caffeine

Caffeine is the most widely consumed psychoactive agent in the world. While caffeine is a safe1,2 and effective stimulant, it is quickly cleared by the body following a rapid onset, even at high doses, causing what is known colloquially as the “caffeine crash”. Theophylline and theobromine, two active metabolites of caffeine, are associated with safety issues at high doses.3,4 Caffeine is primarily metabolized by the CYP450 isoenzyme CYP1A2. Genetic polymorphs of CYP1A2 exist that may influence the metabolism of caffeine.5

A potent, but under-studied, CNS stimulant, caffeine has been hypothesized to have a beneficial role in the treatment or prevention of numerous conditions including Parkinson’s, narcolepsy, ADHD, Alzheimer’s, and weight loss.6,7,8,9

About d9-Caffeine

Deuterium is a naturally occurring, stable isotope of hydrogen, with an additional neutron in its nucleus. Selectively substituting hydrogen with deuterium, or deuteration, is a way to alter a molecule’s metabolic profile while maintaining the core pharmacodynamic characteristics.

Deuteration strengthens the chemical bond between two elements. Depending on where deuterium is placed, it has the potential to alter the overall metabolism of a molecule, or to reduce conversion to specific, unwanted metabolites.

Deuteration has been successfully leveraged in several approved and/or late-stage pharmaceutical products.

d9-Caffeine is a deuterated form of caffeine that has similar pharmacodynamic characteristics as caffeine. Unlike extended-release caffeine products, which have failed to achieve the Tmax and Cmax of caffeine, d9-caffeine has demonstrated substantially differentiated pharmacokinetics, including a similar Tmax, higher Cmax, longer half-life, reduced exposure to certain metabolites of caffeine, and lower relative exposure in slow metabolizers of caffeine.

About Lennham Pharmaceuticals, Inc.

Lennham is a privately held, clinical-stage life sciences company focused on the creative application of deuterium chemistry to improve upon highly utilized and well-characterized compounds. Founded in 2019, Lennham’s unique approach to deuteration has enabled it to rapidly develop a pipeline of product candidates, including deuterium-enriched forms of psilocybin, caffeine, and an androgen-receptor agonist.
