Safety,Tolerability and MTD KA2507 (HDAC6 Inhibitor) in Patients With Solid Tumours

Completed · Phase 1

Conditions studied: Solid Tumor, Adult

In brief

The aim of the study is to evaluate the safety/tolerability, pharmacokinetic, and pharmaco-dynamic effects of KA2507 and establish the maximum tolerated dose (MTD). Patients with PD-L1 expressing solid tumors which have relapsed or are refractory to prior treatment will be eligible to participate in this study. Following completion of the multiple ascending dose study, the protocol may be amended to include expansion cohorts in patients with melanoma and/or other solid tumors.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years at the screening visit.
• Patients with histologically or cytologically documented, confirmed diagnosis of advanced malignancy, whose disease failed to respond to or progressed after standard therapy or they could not tolerate standard therapy.
• Measurable or evaluable disease according to RECIST v1.1.
• ECOG performance status of 0 or 1.
• Predicted life expectancy ≥12 weeks.
• For men and women of child-bearing potential, willing to use adequate contraception (i.e., latex condom, cervical cap, diaphragm, abstinence, etc.) for the entire duration of the study.
• If female, must be either postmenopausal, sterilised or, if sexually active, effectively practicing an acceptable method of contraception (either oral, parenteral, or implantable hormonal contraceptives, intrauterine device or barrier and spermicide). Subjects must agree to use adequate contraception during the study and for at least 12 weeks (or longer as per local requirement) after the last dose of study treatment.
• Male subjects agree to ensure that they or their female partner(s) use adequate contraception during the study and for at least 12 weeks (or longer as per local requirement) after the subject receives their last dose of study treatment.

You may not qualify if…

• Patients are not able to provide written informed consent to study participation
• Patients who have been treated with most recent radiotherapy, hormonal therapy, immunotherapy, chemotherapy or investigational drugs within ≤21 days or 5 half-lives (whichever is shorter) from enrolment (screening), and/or who have any unresolved NCI Common Terminology Criteria of Adverse Events (CTCAE) v4.03 > Grade 1 treatment-related side effect (with the exception of alopecia).
• Patient has anemia due to HbS or HbC disease, alpha or beta thalassaemia
• Patient has Glucose-6-phosphate deficiency
• Patient has known or suspected history of cytochrome b5-MetHb-reductase pathway deficiency
• Persons of Navajo, Athabaska Alaskan or Siberian Yakutsk descent
• Patient has untreated severe hypothyroidism
• Patient has laboratory estimations indicating organ system dysfunction:
• Absolute neutrophil count (ANC) <1.5 X 109/L
• Platelets <100 X 109/L
• Hemoglobin <9g/dL
• Total bilirubin >1.5 mg/dL
• ALT and AST >3.0 times the ULN if no liver involvement or >5 times the ULN with liver involvement.
• Calculated creatinine clearance <60mL/min estimated using the Cockcroft-Gault equation:
• Cockcroft-Gault equation: creatinine clearance = (140 - age in years) x (wt in kg)) x 1.23) / (serum creatinine in micromol/l) [For women multiply the result of calculation by 0.85].
• Major surgery (excluding placement of vascular access) ≤21 days from beginning of the study drug or minor surgical procedures ≤7 days. No waiting is required following implantable port and catheter placement.
• Any of the following cardiac criteria:
• Congestive heart failure (CHF), grade III or IV per New York Heart Association (NYHA) classification
• Symptomatic cardiomyopathy
• > Class II Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy
• Unstable angina or new-onset angina
• QTcF interval >470 ms on screening ECG.
• Severe or uncontrolled systemic diseases including uncontrolled hypertension, active bleeding diatheses 10. Any evidence of active infection including active Hepatitis B, Hepatitis C or human immunodeficiency virus 11. The patient has concurrent severe and/or uncontrolled medical disease that could compromise participation in the study (i.e., uncontrolled diabetes, severe infection requiring active treatment, severe malnutrition, chronic severe liver or renal disease, uncontrolled hypertension, active bleeding diatheses).
• Active infection requiring IV antibiotics within two weeks prior to treatment, or evidence of TB infection.
• Hepatitis B, Hepatitis C or human immunodeficiency virus 14. Previously untreated brain metastases. Patients who have received radiation or surgery for brain metastases are eligible if therapy was completed at least 3 weeks previously and there is no evidence of central nervous system disease progression, mild neurologic symptoms, and no requirement for chronic corticosteroid therapy.
