Spots Global Cancer Trial Database for AZD5153 in Patients With Relapsed or Refractory Solid Tumors, Including Lymphomas

Study Description

Brief Summary: This is a first-time-in-man (FTIM) multicenter, dose escalation study designed to investigate the safety, pharmacokinetics, and pharmacodynamics of AZD5153 in patients with malignant solid tumors, including lymphomas.

Detailed Description: The trial will be conducted in two parts, dose escalation and dose expansion. AZD5153 will be investigated as a monotherapy and in combination with olaparib. AZD5153 monotherapy (dose escalation): This part of the study will enroll patients with advanced solid malignancies, including lymphoma, and test safety and tolerability of AZD5153 administered as a monotherapy. The dose escalation will proceed by two-fold increments or through lower doses suggested by the CRM until an MTD as defined by dose-limiting toxicity is reached. Single daily (QD) and twice daily (BID) dosing schedules will be explored in the monotherapy cohort. Additional dose levels or dosing schedules may be evaluated and recommended by study Safety Review Committee (SRC) based on the emerging PK and safety data. When the AZD5153 monotherapy MTD is established, an expansion cohort consisting of up to 12 additional evaluable patients may be enrolled to confirm the safety and tolerability of the MTD. The dose expansion will be initiated and will enroll patients with histologically or cytologically confirmed platinum resistant or platinum-refractory high grade serous ovarian (HGSO) cancer. Mandatory tumor biopsies at screening for ovarian cancer patients will be required for patient enrollment in the MTD dose expansion cohort. Optional on-treatment biopsies will be requested from consenting patients in the ovarian expansion cohort. AZD5153 + olaparib combination: Dose escalation of AZD5153 in combination with olaparib will also be investigated while the AZD5153 monotherapy dose escalation is ongoing and prior to determination of a monotherapy MTD. The starting dose of AZD5153 in combination with olaparib will be a dose that has been shown to be safe and tolerated in monotherapy and has been chosen because clinical exposure achieved at this dose is equivalent to preclinical exposure causing tumour growth inhibition in animal models. If the starting dose in combination with olaparib is safe and tolerated, the dose of AZD5153 will be escalated, using the same method as for the monotherapy part of the study, keeping the olaparib dose fixed at 300 mg BID. Intermittent schedules as well as continuous BID or QD dosing of AZD5153 in combination with 300 mg BID olaparib might be tested until a safe and tolerated combination dose and schedule is determined. However, the total dose per cycle of AZD5153 used in combination with olaparib won't exceed the total dose per cycle that has been shown to be safe and tolerated as a monotherapy, and won't be higher than the dose declared to be the monotherapy MTD. If intermittent dosing is explored then the CRM will consider cumulative dosing rather than daily dosing. AZD5153 and olaparib will be administered in continuous cycles of 21 days. The combination dose escalation part will run in parallel with the AZD5153 monotherapy part (dose escalation and expansion) and will continue until a safe and tolerated combination dose of the two agents is declared. Mandatory paired tumor biopsies at screening and on-treatment will be required for patients enrolled into the combination dose escalation. Once a dose and schedule of AZD5153 in combination with olaparib is established, up to 12 additional evaluable patients might be enrolled to confirm the safety and tolerability of the dose and schedule of AZD5153 and olaparib in one or more of the indications where clinical activity is observed. Patients with platinum-resistant or platinum-refractory HGSO cancer, triple negative breast cancer, metastatic castration resistant prostate cancer, or pancreatic ductal adenocarcinoma will be eligible for the expansion cohort.
