  1. MEDITERRANEAN SCHOOL OF ONCOLOGY Ritmi circadiani e qualità di vita: actigrafia e nuovi orizzonti nel carcinoma della mammella Roma, 28 Novembre 2008 Cronomodulazione e farmaci orali Giuseppe Tonini g.tonini@unicampus.it Oncologia Medica Universita’ Campus Bio-Medico, Roma

  2. Chronobiology • Chronobiology is the study of the temporal relationships of biological phenomena • Rhythms that fluctuate on a 24-hour time scale are known as circadian rhythms. • The best-known circadian rhythms • body temperature • hormone secretion • metabolism • sleep/wake cycle

  3. Physiology of Circadian Rhythmicity • Prominent daily variations also occur in • endocrine, • thermoregulatory, • cardiac, • pulmonary, • renal, • gastrointestinal, • neurobehavioral functions Harrison

  4. Circadian rhytms in colorectal cancer patients Mormont MC et al, Chronobiol Int 2002

  5. Properties of circadian rythms • Ubiquitous (cyanobacterias, plants, rodents, humans) • Endogenous (persist in the absence of environmental cycles) • Circadian clock genes

  6. Circadian gene expression

  7. In vitro circadian expression of cell cycle genes Delaunay F et al, J Biol Chem 2001

  8. Functional classes of cycling transcripts in cultured rat fibroblasts Delaunay F et al, J Biol Chem 2001

  9. Chronobiology: implications for cancer therapy • Chronotherapy aims to adapt the timing of drug administration according to the circadian rhythms of cancer and normal cells. • Administration of drug at a circadian time when it is best tolerated can achieve best antitumour activity. Mormont and Levi, Cancer 2003

  10. Chronobiology: implications for cancer therapy Circadian rhythms in anticancer drug tolerability in laboratory mice or rats. The least toxic dosing time is indicated as a function of the rest-activity cycle. Mormont and Levi, Cancer 2003

  11. How administer chronotherapy: the multichannel pump • Centralized programmation • Any modulation of delivery rate • 4 reservoirs (100-2000 ml) • Rates from 1 to 3000 ml/h • Safeties • Alarms • Very expensive!!!!

  12. New advances in chronotherapy Phase I, II, III trials are on-going and the results are interesting!!!!

  13. Oxaliplatin and capecitabine in vitro synergistic effect

  14. Capecitabine Chronomodulated Capecitabine

  15. Weekly infusion of oxaliplatin • Phase II studies with weekly or biweekly oxaliplatin have demonstrated low levels of toxicity and high clinical activity (Rosati G, Ann Oncol. 2001 and Oncology, 2004; Santini D, Medical Oncology, 2004; Scheithauer W, Ann Oncol, 2003; Kemeny N, Ann Oncol, 2002; Chao Y et al, Br J cancer, 2004) • The weekly oxaliplatin schedule leads to a higher dose-density and a higher total dose administered (Rosati G, Ann Oncol. 2001; Santini D, Medical Oncology, 2004) • The weekly oxaliplatin schedule may lead to a better and more continous synergistic action with capecitabine administered for 14 days

  16. Metastatic colorectal cancer (Folinic Acid, 5-FU, Oxaliplatin) Infusion flow Constant Chrono Toxicity p Oral mucositis gr 3-4 74% 14% <10-4 Neuropathy gr 2-3 31% 16% <10-2 Responding rate 30% 51% <10-3 Toxicity and efficacy of chronomodulated chemotherapy Lévi et al. JNCI 1994 ; Lancet 1997 ; Lancet Onc 2001

  17. Chronotherapy trials in metastatic breast cancer

  18. Experiences of chronomodulated chemotherapy at Campus Bio-Medico

  19. Continuous infusion of oxaliplatin plus chronomodulated capecitabine in 5-fluorouracil- and irinotecan-resistant advanced colorectal cancer patients. Santini D, Vincenzi B, La Cesa A, Caricato M, Schiavon G, Spalletta B, Di Seri M, Coppola R, Rocci L and Tonini G. Oncology. 2005;69(1):27-34. Chronomodulated administration of oxaliplatin plus capecitabine (XELOX) as first line chemotherapy in advanced colorectal cancer patients: phase II study.

  31. Patients’ characteristics

  32. Toxicity

  33. Efficacy

  34. Phase I study of intermittent and chronomodulated oral therapy with capecitabine in patients with advanced and/or metastatic cancer. Santini D, Vincenzi B, Schiavon G, La Cesa A, Gasparro S, Vincenzi A and Tonini G. BMC Cancer. 2006; 24;6:42

  35. Schedules and end-points Schedule: Capecitabine 1500-2750 mg/mq (gg1-14q21): ¼ h 8, ¼ h 18, ½ h 23. Endpoints: • Maximum-tolerated dose • Dose-limiting toxicities • Safety

  36. Patients’ characteristics

  37. Results • Most common toxicities: fatigue, diarrhoea and hand foot syndrome. • Only 1/9 pts treated at capecitabine dose of 2,750 mg/m2 had DLT toxicities (fatigue G4). • No other episodes of DLT were observed at the same dose steps and at lower doses of capecitabine. • The dose of 2,750 mg/m2 is recommended for further study. • Tumor responses were observed in patients with metastatic breast (6 PR) and colorectal cancer (3 PR).

  38. Conclusions

  39. Conclusions • Circadian rhythms modulate cell functions relevant for: - anticancer agent pharmacology - Cancer processes • New advances in cancer chronotherapy : • Programmable drug delivery devices • Relevance shown in Phase I, II & III clinical trials

  40. Conclusions • In our experience chronomodulated chemotherapy is effective and well tolerated • Our results clearly highlight the need for new trials to verify the real clinical impact of this new way of chronomodulated capecitabine administration in combination with other active drugs in solid tumors.
