Dr. Paul Reid, CEO and Co-FounderCeltic Biotech strives to become the pillar of hope for these patients and their families.
The visionary biopharmaceutical company is at the forefront of transforming cancer treatment, redefining pain therapy, and pioneering breakthrough solutions for a wide array of chronic health conditions.

Derived from specialised receptor-binding proteins found in the venom of the South American rattlesnake Crotalus durissus, Celtic Biotech’s therapeutic candidates provide ease-of-use for oncologists, have a superior side effect profile, potential to increase survival, enhance treatment efficacy whilst reducing healthcare costs for payers.
"We aspire to offer terminally ill patients not just treatment but effective, evidence-based solutions, delivering hope, pain relief, and disease remission," says John Reid, COO & co-founder of Celtic Biotech.

Its inception is rooted in the personal experiences of the founders John Reid and Dr. Paul Reid, who were deeply impacted by individuals close to them diagnosed with terminal cancer. With his extensive expertise in snake venom neurotoxins, Dr. Reid, pursuing venom-related therapeutics, sought guidance from the National Cancer Institute, USA, which suggested crotoxin as a possible candidate.
Dr Reid successfully isolated the protein and proceeded to study it in his lab. The drug subsequently exhibited remarkable efficacy in a patient who faced limited options with a life expectancy of six months. The patient’s recovery spurred the exploration of crotoxin's therapeutic potential, setting the stage for the establishment of Celtic Biotech and its ongoing research and development.
To confirm crotoxin’s safety and efficacy, the Celtic Biotech team commenced human Phase I trials in France with the approval of French clinical regulatory authorities. In part one of the trials, the drug indicated clear safety at low dose levels and physicians moved quickly to the second part of this innovative trial incorporating the use of higher escalating dosages. The safety profile of the drug was reaffirmed in the second part, with two out of six patients showing stabilisation in both primary and secondary tumors, while two others exhibited primary tumour stabilisation, all within 40 days, demonstrating crotoxin’s potential efficacy even without establishing the maximum tolerated dose.
Due to the pronounced safety profile, in addition to the suggestion of efficacy, the part 2 trial was also curtailed from the planned 12 patient recruitment in order to develop an upgraded part 3 protocol. This newer study will commence with higher doses, employing faster intra-patient dose ramping and extended treatment periods that is expected to provide greater indications of efficacy.
Having received approval for this third and final part of its Phase I trial, the company plans to recruit 24 advanced stage patients with trial commencement mid-2024.
The company’s product pipeline has many innovative therapeutic candidates for various health conditions. CB-6, a drug derived from cobra venom, demonstrates an ability to enhance the efficacy of other anti-cancer and chemotherapeutic agents. It also shows promise in ameliorating chronic kidney disease, a condition that currently lacks significant treatment options for humans.
Another drug, CTC-310, is a combination product comprising CB-24 and CB-6. In animal models, it exhibits positive responses in terms of growth inhibition, laying the groundwork for potential Phase II clinical trials in specific cancers like pancreatic and colon.

Joining the line-up is CB-5, a novel drug for cancer and gene therapy. These peptide-based membrane interactive compounds offer an effective mechanism of action distinct from conventional chemotherapy. As a protein, its novelty extends to its effectiveness in animals models when administered by mouth.
Distinguished with a combination of promising therapeutic products and a steadfast commitment to the welfare of terminally ill patients, Celtic Biotech is driven to embrace innovation, new challenges, and explore novel approaches as it sprints towards the goal of revolutionizing treatments for cancer, pain, and chronic health conditions.
