Guerrilla Tactics in Pharmaceutical Innovation and Testing Dr. V. Ravi Chandran R&D Practitioner Life Enhancing Technologies, LLC. Allen, TX USA
Questions in my mind: Do I develop all the Drugs at one shot? Platform Technology? Do I develop one Molecule at a time? What area do I apply this Technology?
Status in the early 2000 I wanted to increase the efficacy and reduce the toxicity i.e. Increase the Therapeutic Index Efficacious Toxic Drugs entering market Examples
Leading Causes of Death *JAMA Vol. 284, No.4, July 26, 2000
Guerrilla Tactic – 1 : Narrow area of attack with maximum impact Among Heart Diseases, Heart Attack is the leading cause of death in both men and women* *World Health Report 2004. Changing History, WHO 2004 pp 120-124 ISBN 92-4-156265-K
CLASSICAL AGE OLD DRUG • What is Aspirin? • Chemically it is Acetyl Salicylic Acid
Guerrilla Tactic – 2 : Solution is sometimes right before the eyes
Guerrilla Tactic – 3 : New association among unrelated concepts Can we therefore develop a new anti-platelet drug that is effective, but has minimal or no side effects? A drug/chemical that thins blood is an effective cardio-protective agent. Question Important Conclusion
Guerrilla Tactic – 4 : Specificity of Approach to New Drug Development Naturally Occurring Must have active group to form covalent permanent bond We will attach a suitable chemical group to the existing drug to eliminate its toxicity and improve Therapeutic Index. Non Toxic Chemical Group Must be detached & excreted or assimilated Good Carrier to Site of Action Strategy Group Selection Criteria
Guerrilla Tactic – 5 : Look Inward What is the most Advanced, compact Highly energy efficient, Lean, mean Fighting machine? Where do I Look for solution To this question? Human Body
Guerrilla Tactic – 6 : Versatile L - Threonine L - Tyrosine Which Amino Acids? Containing OH group L – Hydroxy Proline L – Serine
Surprising Results in Animal Models All 3 Amino Acid Esters are equal effective L – Threonine ester is better than other two and Aspirin None of the 3 Amino Acids Esters showed any toxicity in rat models
Guerrilla Tactic – 7 : Creativity turns Problems into Opportunities How to rapidly advance a NCE without an IND from Lab to Clinical Trials
Guerrilla Tactic – 8 : Simple Techniques are sometimes most useful What can be an effective, simple and reliable technique to measure effectiveness of anti-platelet drugs in humans
Human Clinical Trials Percentage increase in clotting time PLATROL vs.. Aspirin (Bayer) at 81mg dose based on 5-day average increase. The two PLATROL blocks shown above correspond to two separate volunteers who took the test drug over a period of 5 days. The third volunteer took Bayer Aspirin for 5 days. As per Figure 2, increase in clotting time for PLATROL occurred on the very first day of drug intake, and remained higher than Bayer ASA during the subsequent administrations.
CONCLUSIONS L-Threonine ester of Aspirin is a good carrier of Acetyl Group Are we finally getting closer to finding a “super” Aspirin? Are there better carriers of Acetyl Group than Salicylic Acid? Salicylic Acid is also a good carrier of Acetyl group Acetyl group is responsible for Anti-Platelet Activity of Aspirin
Guerrilla Tactic – 9 : Capitalize on what others totally missed Let us go back and take one more look at Aspirin and Salicylic Acid.
Guerrilla Tactic – 10 : Nature has the Answer Is there a naturally occurring molecule (that is essential to the human body) comes very close to our requirements Yes! Make acetyl ester of all other naturally occurring OH containing Amino Acids. Acetylate L-Tyrosine and test it for anti-platelet activity.
Anti-platelet Activity of Acetylated naturally occurring OH containing Amino Acids
Rat Whole Blood Clotting Time (min) Doses: Vehicle, 10, 20, 50 and 100 mg/kg
Dramatic results with Acetylated Amino Acids! Both at 81 and 325 mg dose, Bayer Aspirin increased clotting time only by 13% O Acetyl Serine increased clotting time by 23% O Acetyl Tyrosine increased clotting time by more than 50% and it was sustained after 24 hrs
Advantages of Acetylated Amino Acids • Non-toxic • All metabolites are natural to human body • All 4 AA are good carriers of acetyl group • Mechanism of action is identical to Aspirin • No Toxicity whatsoever • All AAA are nutritional supplements • Require no FDA approval to test • No NDA needed for marketing • Ideally suited for long term therapy
Guerrilla Tactic – 11 : Synergy Now, how about Acetylated Dipeptides Will they have any Anti – platelet activity? Synthesized O,O-Diacetyl Serine-Serine O,O-Diacetyl Serine-Tyrosine O,O-Diacetyl Serine-Threonine
Human Trial Dose 600 mg of O,O-Diacetyl Seryl Serine
Salient Features of Di-Acetylated Dipeptide • Rapid increase in clotting time (up to 87.5%) • Sustained increase in clotting time (37.5%) up to 8 days! • Is it as good as dissolving clot like TPA? Or it can replace Aspirin in sudden heart attack? Likely so. • Non Toxic • No Side effects or adverse reactions • Qualifies as nutritional supplement, hence requires no IND or NDA to test in human subjects • Qualifies for matter of composition patent, as it is novel, and patentable.
Summary Largest Drug Pipeline in the World 9000 molecules in 3 years Better Alternatives for 68 out of top 200 – $ 120 Bill in sales Creative processes and Guerrilla tactics Numerous Patents covering 80% of the market Better Alternatives for 6 out of top 10 – $ 41 Bill in sales
Be on the lookout for S(-)Ketorolac- L-Threonine Ester, a superior pain killer of narcotic strength, but with no addiction potential AAA – Once a day capsules, non-toxic, safe and effective cardio-protective agent KeraKlear optic drops for dry eyes …
