Caspofungin Maximum Tolerated Dose in Patients With Invasive Aspergillosis
A Phase II Dose Escalation Study of Caspofungin in Patients With Invasive Aspergillosis
Panoramica dello studio
Descrizione dettagliata
Due to its efficacy and a broad antifungal spectrum against relevant fungal pathogens, lack of cross-resistance to azoles and amphotericin B, documented efficacy against human Aspergillus infections, favorable pharmacokinetic properties, and excellent tolerability according to the current data, caspofungin is a highly promising candidate for improving the results of treatment of invasive fungal infections.
Preclinical and clinical data indicate a dose dependent antifungal efficacy of caspofungin as well as of other echinocandins such as micafungin and anidulafungin. Thus it appears reasonable to investigate the impact of higher doses of caspofungin to improve the results already achieved with this component so far.
The maximum tolerated dose (MTD) of caspofungin and the distribution of the drug in patients following administration of doses of 70 mg or more are not yet known. We therefore investigate the safety, tolerability and pharmacokinetics of caspofungin in rising doses in a dose escalation study in adult patients with proven or probable invasive aspergillosis.

Inclusion Criteria:
- Immunocompromised due to hematologic malignancies, bone marrow failure syndromes, hematopoietic stem cell transplantation, solid organ transplantation, other conditions resulting in severe neutropenia, HIV infection, prolonged corticosteroid therapy, treatment with other immunosuppressive medications, or other immunocompromising conditions that place patients at risk for invasive fungal infections.
- Evidence of proven or probable invasive aspergillosis, by modified EORTC criteria
Exclusion Criteria:
- Concomitant other systemic antifungal agents are not permitted on study.
- Chronic invasive fungal infection, defined as signs/symptoms of invasive fungal infection present for > 4 weeks preceding entry into study

Safety and Tolerability of Caspofungin in Four Escalating Dosages in Adult Patients With Hematologic Malignancies and Proven or Probable Invasive Aspergillosis
Lasso di tempo: End of caspofungin treatment, treatment duration varied between 3 and 29 days (mean: 20.5; median: 24.5)
|
Endpoints of safety and tolerability are the number of toxicity-related study therapy discontinuations and grade III and IV clinical and laboratory events, as evaluated on the basis of current NCI criteria.

Efficacy of Caspofungin in Four Escalating Dosages in the Treatment of Proven or Probable Invasive Aspergillosis.
Lasso di tempo: End of caspofungin treatment; 4 weeks follow-up; 12 weeks follow-up
|
Numbers of patients in each dose cohort according to invasive aspergillosis (IA) outcome at end of protocol treatment (EOT), 4 weeks follow-up (4w FU) and 12 weeks follow-up (12w FU), respectively. 12w FU was only required for patients with a CR or PR at the 4w FU. Definitions: CR: resolution of all attributable symptoms, signs, and radiographic or bronchoscopic abnormalities. PR: clinically meaningful improvement in attributable symptoms, signs, and radiographic (min. 50% decrease) or bronchoscopic abnormalities. Stable disease (SD): no improvement in attributable symptoms, signs, and radiographic or bronchoscopic abnormalities. Failure: deterioration in attributable clinical or radiographic abnormalities necessitating alternative antifungal therapy or resulting in death. Relapse: reemergence of IA after EOT following CR, PR or SD or early withdrawal. |
