A Study of TAK-676 as Single Agent and TAK-676 in Combination With Pembrolizumab in Adults With Advanced or Metastatic Solid Tumors

EU CTIS ID: 2023-505627-30-00

What this study is testing

Dose escalation: To determine the safety and tolerability of escalating doses of dazostinag administered as an SA or in combination with pembrolizumab in patients with advanced or metastatic solid tumors. Japan safety lead-in: To determine the safety and tolerability of dazostinag in combination with pembrolizumab in Japanese patients with advanced or metastatic solid tumors. Expansion phase: To determine the safety and tolerability of dazostinag in combination with pembrolizumab with or without chemotherapy in patients with previously untreated metastatic or unresectable, recurrent SCCHN. To determine the safety and tolerability of dazostinag in combination with pembrolizumab in patients with previously treated recurrent locally advanced or metastatic MSI-H/dMMR CRC and MSS/pMMR CRC.

Who can take part

You may be able to join if

  • Adult male or female patients aged 18 years or older. • For Japan safety lead-in: Japanese who are living in Japan.
  • Clinically significant toxic effects of previous therapy have recovered to Grade 1 (per NCI CTCAE Version 5.0) or baseline, except for alopecia, Grade 2 peripheral neuropathy, and/or autoimmune endocrinopathies with stable endocrine replacement therapy.
  • In dose escalation Part 1 (not applicable for the Japan safety lead-in), once peripheral evidence of dazostinag pharmacodynamic stimulation of the innate and/or adaptive immune system is observed in the blood and/or an imaging response ([CR]/[PR]) is observed in at least 1 patient, subsequent patients must: • Have at least 1 lesion amenable for biopsy. • Agree to have 2 tumor biopsies: 1 during the screening period and 1 while on dazostinag treatment. In dose expansion Parts 2 and 3 (with the exception of the safety lead-in in Part 2B), patients must be willing to consent to mandatory pretreatment and on-treatment tumor biopsy, if deemed safely accessible. In Parts 1, 2 and 3 once the target number of paired biopsies have been collected and analyzed to evaluate intra-tumor pharmacodynamics, additional paired pretreatment and on treatment biopsies will be optional, but not required.
  • Patients must have at least 1 RECIST v.1.1–evaluable measurable lesion. For the dose escalation phase (Part 1) only, nonmeasurable only disease is acceptable.
  • PK/pharmacodynamic blood must be drawn on a peripherally-inserted catheter. Dazostinag is preferentially administered through a central line, but peripheral infusion is acceptable. If a peripheral line is used for dazostinag and/or pembrolizumab infusion, it must be separate than the one1 used for PK/pharmacodynamic collection.
  • Female patients must be: • Postmenopausal (natural amenorrhea and not due to other medical reasons) for at least 1 year before the screening visit, OR • Surgically sterile, OR • If they are of childbearing potential, agree to practice 2 effective methods of contraception (see Section 8.9) at the same time, from the time of signing the informed consent through 180 days after the last dose of study drug(s), OR • Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient. – Note: Periodic abstinence (eg, calendar, ovulation, symptothermal, postovulation methods), withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception.

You likely can't join if

Chronic, stable atrial fibrillation on stable anticoagulation therapy, including low molecular weight heparin, is allowed.
  • Chronic, active hepatitis (eg, patients with known hepatitis B surface antigen seropositive and/or detectable HCV-RNA). • Note: Patients who have positive hepatitis B core antibody can be enrolled but must have an undetectable serum hepatitis B virus-DNA. Patients who have positive hepatitis C virus antibody must have an undetectable HCV-RNA serum level. However, if the patient enrolls in the study, they will be monitored based on the local or institutional guidelines.
  • For patients in the dose escalation SA Part 1A only: refusal of standard therapeutic options.
  • For patients receiving pembrolizumab only: contraindication and/or intolerance to the administration of pembrolizumab. For patients receiving chemotherapy in Part 2B: contraindication and/or intolerance to the administration of both platinum agents (cisplatin and carboplatin) and/or 5-FU.
  • Any illness, metabolic dysfunction, physical examination finding, or clinical laboratory finding that give reasonable suspicion of a disease or condition that would contraindicate the use of an investigational drug or that would limit compliance with study requirements or compromise ability to provide written informed consent.
  • Patient has had any other prior or concurrent malignancy within 2 years prior to enrollment with the following exceptions: adequately treated localized basal cell or squamous cell carcinoma, or curatively treated in situ carcinoma of the cervix or breast. Other exceptions may be considered upon sponsor consultation.
