NCT05707832 | Not yet recruiting | Invasive Candidiasis

A Study of ABCD for Injection in Subjects With Invasive Candidiasis and Invasive Aspergillus
Sponsor:

CSPC Ouyi Pharmaceutical Co., Ltd.

Brief Summary:

This is a multi-center, open-label, non-controlled, single-arm clinical trial to evaluate the safety, efficacy and population pharmacokinetics of Amphotericin B cholesteryl Sulfate Complex for Injection domestic formulations (ABCD) in the treatment of confirmed invasive candidiasis (IC) and confirmed/clinically diagnosed invasive aspergillus (IA) disease.

Condition or disease

Invasive Candidiasis

Invasive Aspergillosis

Intervention/treatment

Amphotericin B cholesteryl Sulfate Complex for Injection

Phase

Phase 3

Detailed Description:

The study includes a screening period (day -14 to day -1), a baseline period (day 1), a treatment period, and a follow-up period (14±3 days after the end of administration). Eligible subjects will receive intravenous ABCD infusion. A test dose of 2 mg/10 mL will be given at baseline, followed by titration after the evaluation of the subjects' symptoms, signs and tolerance by investigator, until reaching the recommended dose of 3.0-4.0 mg/kg once a day for treatment. IC subjects will receive ABCD intravenous therapy for a minimum of 2 weeks, and a maximum of 14 days after the first negative turn of candida culture in blood or other normal sterile sites and the symptoms and signs of infection disappear/improve significantly, up to a maximum of 6 weeks. IA subjects will be treated with ABCD for at least 2 weeks and up to 6 weeks. After the end of intravenous therapy, according to the individual condition of the subjects, pathogens, drug sensitivity test, and the therapeutic effect of ABCD, the investigator will make a comprehensive judgment on whether to give sequential therapy drugs, but the total course of treatment shall not exceed the duration specified in the above scheme (the number of days of ABCD intravenous therapy plus the number of days of sequential therapy shall not exceed 6 weeks). The study will end when the last subject completed the follow-up period.}}

Criteria
Inclusion Criteria
  • Age ≥18 years old, male or female;
  • Subjects who meet the EORTC-MSG diagnostic criteria and are diagnosed with invasive candidiasis (confirmed) or invasive aspergillus disease (confirmed or clinical) according to the Revised Definition of Invasive Mycosis: IC confirmed subjects are positive candida culture reports from blood or other sterile samples obtained within 48 hours prior to enrollment; Or the histopathological/cytopathological examination report of needle aspiration or biopsy specimens from normal sterile except mucosa within 2 weeks showed the presence of candida; IA confirmed subjects are defined as diseased tissue (sterile sampling) obtained within 4 weeks prior to enrollment with definite fungal presence (cytology, microscopy, or culture, etc.). The clinical diagnosis of IA includes at least one host factor, one clinical criterion, and one microbiological criterion (serum, sputum, bronchoalveolar lavage fluid, bronchial brush specimen, or sinus extract indicating positive Aspergillus GM test);
  • All subjects agreed to use contraception from the time signed the informed consent to 6 weeks after the end of the last dose;
  • Female subjects must meet one of the following conditions: have surgical sterilization; postmenopausal, menopause at least 1 year; or for those with fertility, must satisfy the following conditions: negative human chorionic gonadotropin (HCG) serum test results prior to enrollment; avoidance of sexual behavior throughout the study period, or agreement to use a recognized and highly effective contraceptive measure [defined as being able to be used consistently and correctly with a failure rate of less than 1% per year, such as: condoms, combined hormones (including estrogen and progesterone) combining inhibit ovulation, progestin contraception combined with ovulation suppression, intrauterine device (IUD), intrauterine hormone release system (IUS), bilateral tubal ligation, bilateral vasectomy], and the contraceptive methods remained unchanged throughout the study period;
  • Male subjects must have been surgically sterilized or their female partners must have met any of #4 above, and their contraceptive methods remained unchanged during the study period;
  • Subjects and/or guardian fully understand, voluntarily participate in this study and sign the informed consent form.
Exclusion Criteria
  • Allergic to amphotericin B drugs or cholesterol sulfate complex antifungal drugs;
  • IC subjects received systemic antifungal therapy for ≥3 days within 1 week prior to enrollment (subjects with no improvement in symptoms of infection after treatment or with positive blood culture candida can still be enrolled; Subjects with neutropenia can use triazole prophylaxis for an unlimited days);
  • IA subjects received systemic antifungal therapy for more than 96 hours within 1 week prior to enrollment (subjects with no improvement in symptoms of infection after treatment or those with positive microbiological criteria can still be enrolled), or prophylactic therapy for more than 13 days or common amphotericin B with cumulative dose of more than 10 mg/kg within 10 days prior to enrollment, or use amphotericin lipids with a cumulative dose of more than 15 mg/kg;
  • Evidence of infection in subjects is limited to positive candida cultures in urine (other than those diagnosed with pyelonephritis), sputum and bronchoalveolar lavage fluid, catheter tops, drainage fluid, or other mucous membranes or superficial skin surfaces (e.g. vagina or other external genitalia, colon, oropharynx, esophagus, skin folds, nail beds, etc.);
  • Subjects with suspected candida endocarditis, osteomyelitis, arthritis, endophthalmitis, liver and spleen abscess, suppurative thrombophlebitis, or central nervous system infection;
  • Candida culture positive samples collected 24 hours after the non first placement of the catheter or drainage tube at the sterile site;
