简要总结
The purpose of this study is to evaluate safety, tolerability and pharmacokinetics of intravesical cis-urocanic acid in patients with primary or recurrent non-muscle invasive bladder cancer.
详细描述
This is a single dose, dose-escalating, Phase I study to evaluate safety, tolerability and pharmacokinetics of intravesical cis-urocanic acid (cis-UCA) in patients with primary or recurrent non-muscle invasive bladder cancer.
The primary objectives is to evaluate safety and tolerability of cis-UCA after a single intravesical instillation with escalating doses and to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of cis-UCA after a single intravesical instillation with escalating doses.
The secondary objectives are to evaluate pharmacokinetics of cis-UCA after a single intravesical instillation with escalating doses, to obtain preliminary information on possible anti-tumor effects of cis-UCA by cystoscopy and histological evaluation after a single intravesical instillation with escalating doses, and to evaluate the effects of cis-UCA on different surrogate biochemical markers on tumor growth and differentiation after a single intravesical instillation with escalating doses.
The key eligibility criteria are the following: Patients with primary or recurrent non-muscle invasive bladder cancer; eligible for intravesical treatment; age 18-80 years; WHO performance status 0-2; acceptable liver, renal and hematological function within 30 days prior to inclusion.
At minimum 3 patients and at maximum 24 patients is planned to be included in the study. The fixed dose-escalation levels will be used.

入选标准
- •Informed consent obtained prior to any screening procedures
- •Patients with primary or recurrent non-muscle invasive bladder cancer
- •The patient is eligible for intravesical instillation
- •Age 18-80 years
- •WHO performance status 0-2
- •Body weight at least 50 kg for males and 45 kg for females; body mass index (BMI) 18-35 kg/m2
- •Diagnostic cystoscopy performed within 30 days prior to screening visit
- •Negative pregnancy test (premenopausal female patients) at screening and use of adequate contraceptive measures (both male and female patients) throughout the study and 30 days after the cis-UCA dose oPremenopausal female volunteers should be either surgically sterile or using a reliable contraception method: intrauterine device (hormonal or non-hormonal); oral combination pill or hormonal contraception patch; or two of the following: intra-vaginal hormonal ring, oral contraceptive containing progestin only, spermicidal foam, condom, sterilization of male sexual partner (surgical vasectomy) oPatients with no current heterosexual relationship may be included according to the judgment of the Investigator oIf menopause occurred 2 years ago at the minimum, no contraception is required for female participants, nor pregnancy tests oReliable contraception for male patients is concordant with above listed methods for females, as applicable
- •Acceptable liver function, renal function and hematological status at screening
- •Urinalysis showing no clinically significant abnormalities except those attributable for bladder cancer
排除标准
- •Previously diagnosed bladder fibrosis
- •Total bladder capacity estimated by cystoscopy to be less that 150 ml
- •Urinary incontinence of that severity that according to the opinion of the Urologist/Investigator would compromise the ability of the patient to retain the study drug intravesical instillation for one hour
- •Severe irritative voiding symptoms, such as urgency, frequency and nocturia that could compromise protocol objectives in the opinion of the Urologist/Investigator
- •Serious disease (e.g., hydronephrosis, renal or liver failure or other condition) that could compromise protocol objectives in the opinion of the Urologist/Investigator
- •Active, uncontrolled bacterial, viral, or fungal infections, including urinary tract infection
- •Previous treatment with radiotherapy, or systemic chemotherapy.
- •Intravesical instillation(s) within 6 months with BCG or cytostatic agents
- •Known allergy to cis-UCA-instillation solution (see Section 5.1 for excipients).
- •Having participated in a clinical study with cis-UCA previously
- •Known any serious immunodeficiency condition
- •Donation of blood or participation in another drug study within 60 days (males) or 90 days (females) before the intravesical instillation in this study
- •Any clinically significant laboratory test result (including positive tests for HIV and hepatitis B or C) according to Investigator/Urologist
- •Excessive use of alcohol (on average more than 24 units per week for males, and more that 16 units per weeks for females; unit = 4 cl spirits or equivalent)
- •Clinically significant illness (except bladder cancer) within 30 days before the screening visit or any other condition, such as vesicourethral reflux (VUR), or complicated urinary stone disease that in the opinion of the Investigator would interfere with the evaluation of the study results or constitute a health hazard for the patient
- •Regular use of urine alkalinizing agents/drugs (e.g., acetazolamide, calcium phosphates, aluminium hydroxide, sodium bicarbonate, sodium carbonate, sodium citrate, potassium citrate) that might interfere with the evaluation of the study results
- •Unwillingness or doubtful capacity to comply with the protocol
- •Doubtful availability, in the opinion of the Investigator, to complete the study
- •Poor peripheral venous access -
