About this study
Official title: A Phase 1, Open-label, Multi-center, Dose Escalation and Dose Expansion Study of NKTR-255 in Relapsed or Refractory Hematological Malignancies
Patients will receive intravenous (IV) NKTR-255 in 21 or 28 day treatment cycles. During the Part 1 dose escalation portion of the trial, patients will either receive NKTR-255 as monotherapy, NKTR-255 administered as a doublet with daratumumab subcutaneous (DARZALEX FASPRO TM), or NKTR-255 administered as a doublet with rituximab. After determination of the recommended Phase 2 dose (RP2D) of NKTR-255, NKTR-255 will be evaluated in Part 2. During the Part 2 dose expansion portion of the trial, patients will either receive NKTR-255 as monotherapy, NKTR-255 administered as a doublet with daratumumab subcutaneous (DARZALEX FASPRO TM), or NKTR-255 administered as a doublet with rituximab.
This is a Phase 1 study to evaluate safety and tolerability of NKTR-255 alone and in combination with daratumumab or rituximab.
Read the detailed description
NKTR-255 is a cytokine that is designed to regulate T and natural killer cell activation, proliferation and promote their anti-tumor effects.
This is a Phase 1, open-label, multi-center, dose escalation, dose expansion, safety follow-up, and survival follow-up of NKTR-255 as a single agent and NKTR-255 in combination with DARZALEX FASPRO TM or rituximab. Study treatment is defined as any investigational treatment(s) or marketed product(s), intended to be administered to a study patient according to the study enrollment.
Part 1 will enroll relapsed/refractory multiple myeloma (MM) and Non-Hodgkin's Lymphoma (NHL) patients. In Part 2, Cohort A will enroll NHL patients who have progressed on a chimeric antigen receptor T-cell (CAR-T) product, Cohort B will enroll MM patients who previously received daratumumab and other anti-CD38 therapies to receive NKTR-255 alone and/or in combination with daratumumab, and Cohort C will enroll indolent Non-Hodgkin's Lymphoma (iNHL) patients who previously received rituximab and other therapies to receive NKTR-255 alone and/or in combination with rituximab.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing NKTR-255, NKTR-255 Q21 and Rituximab in people with Multiple Myeloma and Non-Hodgkin Lymphoma, run by Nektar Therapeutics at 13 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Treatment-Emergent Adverse Events and Serious Adverse Events of NKTR-255 as a single agent (time frame: Through study completion, an expected average of 6 months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04136756, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2023.
