Neoadjuvant Pembrolizumab and Axitinib in Renal Cell Carcinoma With Inferior Vena Cava Tumor Thrombus

• Status: Recruiting
• Trial end date: 2029-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of this study is to evaluate whether the combination of Pembrolizumab and Axitinib given in the neoadjuvant setting can change the Inferior Vena Cava Tumor Thrombus burden. A decrease in the size of the tumor thrombus can potentially lead to decrease in surgical complications, improve patient related health outcomes, and improve long term outcomes such as progression free survival and overall survival.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: University of Colorado, Denver
• Collaborator: Cancer League of Colorado

• Women <50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy)

• Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy

• For males with reproductive potential, use effective birth control during treatment with Axitinib and Pembrolizumab is recommended.

• Has had major surgery within 4 weeks or received radiation therapy within 1 week prior to enrollment to the study.

• Has had prior treatment with any anti-programmed cell death (anti-PD-1) or programmed cell death ligand 1 (PD-L1), or an antibody targeting any other immune-regulatory receptors or mechanisms.

• Has received prior systemic anti-cancer therapy for RCC with vascular endothelial growth factor (VEGF)/VEGF receptors (VEGFR).

• Has a history of severe hypersensitivity reaction (e.g., generalized rash/erythema, hypotension, bronchospasm, angioedema, or anaphylaxis) to Axitinib.

• Has a diagnosis of immunodeficiency OR is receiving a systemic steroid therapy greater than Prednisone 10 mg daily or a steroid equivalent, or any other form of immunosuppressive therapy within 7 days prior to enrollment to the study except in the case of central nervous system (CNS) metastases.

Note: Participants with vitiligo, Sjogren's syndrome, Type 1 diabetes, resolved childhood asthma/atopy, hypothyroidism or adrenal or pituitary insufficiency who are stable on hormone replacement are not excluded.

• Has a known additional malignancy that has progressed or has required active treatment in the last 3 years. Note: Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, or carcinoma in situ such as breast cancer in situ, thyroid cancer (papillary, hurthle cell or follicular), or localized prostate cancer are acceptable if they have undergone potentially curative therapy.

• Has known active CNS metastases and/or carcinomatous meningitis.

• Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis.

• ALT or AST above 3 times the upper limit of normal
