New information offered on the 2023 Osteoarthritis Analysis Society Worldwide (OARSI) World Congress in Denver, Colorado recommend that AKL Therapeutics’ investigational oral osteoarthritis (OA) drug APPA could have a twin impact on senescence – the method through which cells cease dividing as a pure consequence of growing older. Senescence performs a serious position within the improvement of many age-related ailments, together with osteoarthritis (OA) [1].
The examine, utilizing a human chondrocyte (cartilage-forming) cell line, was carried out on the Institute of Biomedical Analysis of A Coruña (INIBIC) in Spain. It discovered that APPA seems to not solely cut back the variety of dangerous senescent cells which construct up within the cartilage inflicting irritation – a senolytic impact – however may additionally doubtlessly reverse the senescence course of so cells can perform usually once more – a senomorphic impact.

The examine discovered that APPA considerably lowered the variety of senescent cells (p=0.020) and elevated the variety of cells – indicated by the variety of nuclei (p=0.062) – within the chondrocyte cell line through which senescence had been induced.
Alan Reynolds, Chief Scientific Officer at AKL Therapeutics, says: “These newest findings elevate the tantalising chance that APPA may modify the development of debilitating OA for sufferers by eliminating or delaying the adversarial results of mobile senescence and the method of ageing.”
“Frailty and mobility points have a major impression as we age, typically resulting in folks residing a few years in ache and sick well being. If we will cut back senescence, which contributes to joint injury in OA and is concerned in lots of different age-related ailments, we will hopefully assist enhance folks’s healthspan, so that they age in higher bodily and psychological well being.”
Longevity.Know-how: As we age, dysfunctional senescent cells – typically dubbed “zombie” cells – construct up within the physique whereas secreting dangerous chemical compounds which trigger irritation and injury surrounding tissue – a course of referred to as senescence. As senescence is now identified to play a serious position within the improvement of many age-related ailments, together with OA, Continual Obstructive Pulmonary Illness (COPD), Alzheimer’s, Parkinson’s, osteoporosis and diabetes, senescent cells have change into one of the promising targets for wholesome growing older analysis [2].
Creating a brand new class of medication referred to as senotherapeutics to eradicate or delay the damaging results of this mobile senescence is a brand new frontier in drugs. Senotherapeutics have the potential to extend healthspan by delaying the more severe results of growing older, which would scale back the burden of age-related ailments and will save healthcare techniques billions yearly [3].
David Miles, Chief Govt Officer at AKL Therapeutics, says: “With a novel mechanism of motion, APPA is the one oral drug that targets the a number of signalling pathways in bone, cartilage and irritation concerned in OA, delivering ache aid to a number of joints [4]. With this newest information now displaying that APPA has a possible senomorphic impact, we’ve lately filed a patent software and can look to hold out additional research on different senescence-related ailments to research its potential as a senotherapeutic.”
APPA is an oral, patented, fixed-dose mixture of two synthetically produced, synergistic, secondary metabolites of plant origin. Earlier human medical trials have proven that APPA has a superb security profile, is well-tolerated and reduces ache in OA [5]. Importantly, it has been proven to scale back ranges of cartilage-damaging enzymes and ranges of bone destruction [6]. The Section 2a trial discovered that these with extra extreme illness benefited most from APPA with a statistically vital enchancment in ache vs placebo [5].

AKL is now elevating funding for a Section 2b trial of APPA as a possible remedy for sufferers with extra extreme OA – the biggest affected person group which additionally has the best unmet want [7]. AKL was granted an Innovation Passport for APPA in 2021 by the UK’s Medicines and Healthcare merchandise Regulatory Company (MHRA) which units out an accelerated roadmap of future improvement and regulatory milestones.
There are presently no efficient and effectively tolerated oral therapies that present long-term ache aid or cut back the development of OA, a typical, debilitating, degenerative illness of the joints involving the cartilage, bone, and its surrounding tissues. OA is the commonest joint illness worldwide, affecting an estimated 10% of males and 18% of girls over 60 years of age [8]. Globally, the prevalent circumstances of OA elevated by 113.25%, from 247.51 million in 1990 to 527.81 million in 2019, with OA of the knee contributing most to the general burden [9].
