About Bempegaldesleukin (NKTR-214), Nektar's Lead Immuno-oncology Candidate
Bempegaldesleukin is a CD122-preferential IL-2 pathway agonist designed to stimulate the patient's own immune system to fight cancer. Bempegaldesleukin is designed to grow specific cancer-killing T cells and natural killer (NK) cell populations in the body which fight cancer, which are known as endogenous tumor-infiltrating lymphocytes (TILs). Bempegaldesleukin stimulates these cancer-killing immune cells in the body by targeting CD122 specific receptors found on the surface of these immune cells, known as CD8+ effector T cells and NK cells. CD122, which is also known as the Interleukin-2 receptor beta subunit, is a key signaling receptor that is known to increase proliferation of these effector T cells.1 In clinical and preclinical studies, treatment with bempegaldesleukin resulted in expansion of these cells and mobilization into the tumor micro-environment.2,3 Bempegaldesleukin has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines.
A Phase 1 study evaluating bempegaldesleukin as a single agent in patients with locally recurrent or metastatic solid tumors including melanoma, renal cell carcinoma (RCC), bladder, colorectal (CRC) and other solid tumors is complete. Results from this First-in-Human trial were published in Cancer Discovery and showed encouraging evidence of anti-tumor activity, and a favorable safety and tolerability profile. (Cancer Discov 2019;9:1–11)
In February 2018, Nektar and Bristol-Myers Squibb entered into a global development and commercialization agreement to evaluate the full potential of bempegaldesleukin plus Opdivo® (nivolumab) The agreement includes 7 indications in 4 tumor types including melanoma, renal cell carcinoma, non-small cell lung cancer and bladder cancer.
Additional development plans for bempegaldesleukin include combination studies with additional checkpoint inhibitors, cell therapies and vaccines.
About the Phase 3, Randomized, Open-label Study of Bempegaldesleukin Combined With Nivolumab Versus Nivolumab in Participants With Previously Untreated Unresectable or Metastatic Melanoma (PIVOT-IO-001)
The Phase 3 study will test the effectiveness (how well the drug works), safety, and tolerability of bempegaldesleukin, when combined with nivolumab versus nivolumab given alone in participants with previously untreated melanoma skin cancer that is either unable to be surgically removed or has spread. For more information, please visit clinicaltrials.gov and search NCT03635983.
About the Phase 3, Randomized, Open-label Study to Compare Bempegaldesleukin Combined With Nivolumab to the Investigator's Choice of Sunitinib or Cabozantinib in Patients With Previously Untreated Advanced Renal Cell Carcinoma
The Phase 3 study will compare the overall response rate (ORR) and overall survival (OS) of bempegaldesleukin combined with nivolumab to that of tyrosine kinase inhibitor (TKI) monotherapy (sunitinib or cabozantinib) in IMDC intermediate- or poor-risk patients with previously untreated advanced RCC. For more information, please visit clinicaltrials.gov and search NCT03729245.
A Phase 3, Randomized, Study of Neoadjuvant and Adjuvant Nivolumab Plus NKTR-214, Versus Nivolumab Alone Versus Standard of Care in Participants With Muscle-Invasive Bladder Cancer (MIBC) Who Are Cisplatin Ineligible (PIVOT-IO-009)
The purpose of this Phase 3 study is to see if treatment with bempegaldesleukin (BEMPEG: NKTR-214) in combination with nivolumab (NIVO) or NIVO alone, before and after surgery to remove the bladder, is more effective than surgery alone in participants with muscle-invasive bladder cancer who are not able to receive cisplatin chemotherapy. The co-primary endpoints will be pathologic complete response (pCR) rate and event-free survival (EFS) of BEMPEG plus NIVO versus surgery alone. Secondary outcome measures include pCR and EFS of monotherapy NIVO versus surgery, overall survival and incidence of adverse events. For more information, please visit clinicaltrials.gov and search NCT04209114.
A Phase 3, Randomized, Open-label Study to Compare Adjuvant Immunotherapy of Bempegaldesleukin Combined With Nivolumab Versus Nivolumab After Complete Resection of Melanoma in Patients at High Risk for Recurrence (PIVOT-12)
This phase 3 study will evaluate the efficacy, safety and tolerability of adjuvant bempegaldesleukin (BEMPEG) and nivolumab versus nivolumab in approximately 950 patients in who have had their melanoma surgically removed but who have a high risk of recurrence. The primary endpoint of the trial is recurrence-free survival (RFS) and secondary endpoints include overall survival (OS) and other measures of disease progression. For more information on the study, please visit clinicaltrials.gov and search NCT04410445.
About the Phase 2 Study of the Triplet Combination of Bempegaldesleukin with Nivolumab and Cabozantinib as Compared to Nivolumab plus Cabozantinib for the Treatment of Renal Cell Carcinoma that is Advanced or has Spread (PIVOT-IO-011)
The Phase 2, open-label, randomized trial is designed to assess the efficacy of the triplet combination of bempegaldesleukin (BEMPEG) plus nivolumab and cabozantinib versus the doublet of nivolumab and cabozantinib for patients with previously untreated advanced or metastatic renal cell carcinoma. The first stage of the study will include a dose-finding component for the triplet combination. The trial will assess the safety and tolerability of the triplet combination and will also measure progression-free survival (PFS) and overall survival (OS). The trial is expected to enroll more than 100 patients. For more information, please visit clinicaltrials.gov and search NCT04540705.
About PIVOT-10, a Phase 2, Single-Arm Study of Bempegaldesleukin in Combination With Nivolumab in Cisplatin Ineligible, Locally Advanced or Metastatic Urothelial Cancer Patients
The Phase 2 study will evaluate the anti-tumor activity of bempegaldesleukin in combination with nivolumab by assessing the objective response rate (ORR) in approximately 205 cisplatin-ineligible, locally advanced or metastatic urothelial cancer patients (mUC). The primary endpoint will be ORR by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 per Blinded Independent Central Review (BICR) in patients whose tumors have low programmed cell death ligand (PD-L1) expression. Secondary outcome measures include ORR by RECIST 1.1 per BICR in all treated patients, Duration of Response (DOR) by RECIST 1.1 per BICR in all treated patients and patients whose tumors have low PD-L1 expression, ORR and DOR by RECIST 1.1 per Investigator assessment in all treated patients and in patients whose tumors have low PD-L1 expression and incidence of treatment-related Adverse Events (AEs).
