A Study of TAK-676 With Pembrolizumab After Radiation Therapy to Treat a Number of Cancers

• Status: Recruiting
• Trial end date: 2024-01-18
• Target enrollment: 0
• Participant gender: All

Summary

In this study, people with non-small-cell lung cancer (NSCLC), triple-negative breast cancer (TNBC) and squamous-cell carcinoma of the head and neck (SCCHN) will be treated with TAK-676 and pembrolizumab following radiotherapy. The main aims of this study are to check if people are getting side effects from these combined treatments and how much TAK-676 people with these cancers can receive without getting side effects from it.

Participants will receive radiotherapy, then at least 40 hours later will receive pembrolizumab followed by TAK-676 slowly through a vein (infusion). Participants will receive an infusion of pembrolizumab at the same dose every 3 weeks. Different small groups of participants will receive lower to higher doses of TAK-676 on specific days of a 21-day cycle.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

1. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.

2. Participants must have at least 2 measurable RECIST, V1.1-evaluable lesions, with at least one inside and at least one other outside of the radiation field. The tumor outside the radiation field must be accessible for biopsy, and the participant must consent to tumor biopsy at screening and during treatment.

3. Participants must have pathologically confirmed (cytological diagnosis is adequate) advanced or metastatic NSCLC, TNBC, or SCCHN who have:

• Received or been offered all established standard of care (SOC) treatment options for which they are eligible; and

• Progressed on checkpoint inhibitors in a prior line of therapy.

4. Life expectancy greater than (>) 12 weeks, as assessed by the investigator.

5. Adequate bone marrow, renal and hepatic functions.

6. Left ventricular ejection fraction (LVEF) >50%, as measured by echocardiogram or multiple-gated acquisition (MUGA) scan within 4 weeks before receiving the first dose of study drug.

7. Clinically significant toxic effects of previous therapy have recovered to Grade 1 (per NCI CTCAE, V5.0) or baseline, except for alopecia, Grade 2 peripheral neuropathy, and/or autoimmune endocrinopathies with stable endocrine replacement therapy.

Exclusion Criteria:

1. History of any serious cardiac or cerebrovascular conditions in the last 6 months, including uncontrolled congestive heart disease, unstable angina, myocardial infarction, hypertension greater than or equal to (>=) 160/100 millimeter of mercury (mmHg) in spite of optimal therapy, cardiac arrhythmias, pericardial effusion, cardiomyopathy, or symptomatic stroke. Chronic, stable atrial fibrillation on stable anticoagulation therapy, including low molecular weight heparin, will be allowed.

2. History of brain metastasis unless:

• Clinically stable, (that is, treatment completed >=4 weeks prior) following prior surgery, whole-brain radiation, or stereotactic radiosurgery, AND

• Off corticosteroids.

3. Known history of uncontrolled autoimmune disorders, human immunodeficiency virus (HIV) infection, or other relevant congenital or acquired immunodeficiencies.

4. Chronic, active hepatitis (example, participants with known hepatitis B surface antigen seropositive and/or detectable hepatitis C virus [HCV]-ribonucleic acid [RNA]).

5. Treatment with any investigational products and systemic anticancer drugs (including vascular endothelial growth factor (VEGF) inhibitors), within 14 days or 5 half-lives, whichever is shorter, before Cycle 1 Day 1 (C1D1) of study drugs.

6. Prior radiation to lesions chosen for biopsy or response assessment.

7. Prior radiation to lesions other than those chosen for radiation therapy or biopsy in the current protocol within 4 weeks of C1D1 of study drug(s).

8. Use of systemic corticosteroids or other immunosuppressive therapy, concurrently or within 14 days of start of radiation therapy, with the following exceptions:

• Topical, intranasal, inhaled, ocular, and/or intra-articular corticosteroids.

• Physiological doses of replacement steroid therapy (example, for adrenal insufficiency).

9. Receipt of live attenuated vaccine (example, tuberculosis Bacillus Calmette-guerin [BCG] vaccine, oral polio vaccine, measles, rotavirus, yellow fiver) within 28 days of C1D1 of study drug(s).

10. Recipients of allogeneic or autologous stem cell transplantation or organ transplantation.

11. Ongoing Grade >=2 infection or participants with Grade >=2 fever of malignant origin.

12. Fridericia's corrected QT interval (QTcF) >450 milliseconds (msec) (males) or >475 msec (females) on a 12-lead electrocardiogram (ECG) during the screening period.

13. Grade >=2 hypotension (that is, hypotension for which nonurgent intervention is required) at screening or during C1D1 pre-dose assessment.

14. Oxygen saturation less than (<) 92% on room air at screening or during C1D1 predose assessment.

15. Use of medications that are known clinical organic anion transporting polypeptide 1B1 (OATP1B1) and/or OATP1B3 inhibitors, concurrently or within 14 days of C1D1 of study drugs.

16. Current smoker.

17. Vaping within 90 days of C1D1 of study drugs.

18. Current diagnosis of pneumonitis, interstitial lung disease, severe chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis, other restrictive lung diseases, acute pulmonary embolism, or Grade >=2 pleural effusion or ascites not controlled by tap or requiring indwelling catheters.

19. Treated with other stimulator of interferon genes (STING) agonists/antagonist and toll-like receptors agonists within the past 6 months.
