OBJECTIVES AND ACTIVITIES
Objectlves and aims

'To protect and promote th8 health ol the public tn particular by research into th& nature cases, diagno&s. prevention,
treatment and cure of chronic infection diseases, includino the develi>pm8nt of findings of resobrch into practical
applications for the prevention, treatment and cure of chronic infectio%) disèas$s and in furtherance L>f that primary

Phelix Resèarch & Development {Phèllx R&D) is a medical researth charity. Th8 charity works hand in hand with Phelix
Fran￿, registered in France as an 'Association d'lnlérél Général..
Its team is a strong co.partnership of healthcare professlonals Ipraclitiorws. immunolojists and unlversity researchers,
amongst them Leicester Untversityl ènd voluntee¥s, working tOgeth8r to reach the charity's key objoctivgs.
The overall aim 15 to develop ph8ge-b8sed diagnostic and troatmgnl ol Lyme disease. To-d8t&, we have developed a
novel ph8gè-ba5ed diagnostic method targeting Lyme Borrelia S￿1￿5. This novel diagnostic rnethod showed higher
sensitsvity compared lo the current dia9nosb¢ methods. With furth&r dèveloprn8nt. our phage-basèd method could have
the power to distinguish behyeen active 8nd non-aclive Lyme infection and off8r a promise of earfy Lym8 (Ji89r￿Stics.
In addition to our pioneer wotl( in Lyme dTr8gnostics, we hav& also d6velop8d our pipelines of m&thodolo9ies in isolation
and identification of phages that specifically infect Lyme Borrelia slrains. artd w8 are c￿r￿ntIY activ&ly screening for
phages. Once we identfy phages, we will test th9 efficacy of these phages In killtng Borrelia strain, aThJ develop them
towards therapeutics.
Activty update
Currenuy, the charity is f￿￿$sed on supporting r&sè8r¢h yufrounding bacteriophage virusgs and their potential usès in
¢hronic infection. Could bact8riophages Pfovide aft alL8rnative lo anlibiotscs. providlng a solulK)n to the problem of
increasing anlibiotic resistancg, one of the lar9est th￿Sts lo glob81 heallh?
Bafore reaching this stag&. r8searc* 15 required in the development of new and mor& $8n5i¢4V9 tests for such thron1¢
infections.
The genus of bacteria id8nlified as a target for ￿Se$r¢h being canied out by the Phelix tèam inibally is callèd 8orr&lia
spp. Many of the speci*s within Ih¢s genus are commonly known lo be carried by ticks and I￿e and can cause Lymè
disease, il spread lo humans.
Simultaneously, work is bwng done to givè further in$ight into the pathology and physlology ol major neurodegèn8rative
conditions, specifically neuroborreliosis, BLrtism spectrum disorder and Alzheimer's di58ase. This investigation is to
piovide a firm basis fot Phelix's future resoareh into the relationship be￿an chronic inlèction and neurodegeneT8b"on.
In the year 2021, th¥ charity and the Univèrsity of Leicester have been focuslng on improving the specificity and the
sensitwity of the diagnostic lesl we designed.
Our agreemoftt with Rgd Laboratori&s In Bélgium helped us to gain some retums from ourjoint patent in orrjer lo finance
