What is being measured
The primary outcome is the main question the study is designed to answer.
Phase I: Incidence of dose limiting toxicities (DLTs) of [177Lu]-NeoB
A dose-limiting toxicity (DLT) is defined as a clinically relevant adverse event or abnormal laboratory value not attributable to the disease or disease-related processes under investigation, considered possibly related to [177Lu]-NeoB that occurs within 42 days following the first administration of [177Lu]-NeoB (cycle 1) and meets any of the criteria listed in Table 6-4 (Criteria for defining dose-limiting toxicities).
Measured: Within 42 days following the first administration of [177Lu]-NeoB
Phase I: Determination of Maximum Tolerated Dose (MTD)/ Recommended phase two dose (RP2D) of [177Lu]-NeoB
The maximum tolerated dose (MTD) and/or the recommended phase II dose (RP2D) of [177Lu]-NeoB will be identified:
- MTD is defined as the lowest single dose at which 25% or more of the patients experienced a DLT during the first cycle (6 weeks).
- RP2D is defined as the single dose level below the MTD. The number of cycles recommended for Phase II will be defined based on the cumulative dose toxicities reported during Phase I.
Measured: Within 42 days following the first administration of [177Lu]-NeoB
Phase IIa (Cohorts A, B and C): Individual clinical responses assessed by Response Evaluation Criteria In Solid Tumors (RECIST v1.1)

Phase IIa (Cohorts A, B and C): Changes from baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
The QLQ-C30 is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, a global health status / QoL scale, and six single items. Each of the multi-item scales includes a different set of items - no item occurs in more than one scale. All of the scales and single-item measures range in score from 0 to 100. A higher score for the functioning scales and global health status denote a better level of functioning (i.e. a better state of the patient), while higher scores on the symptom and single-item scales indicate a higher level of symptoms (i.e. a worse state of the patient).
Measured: 15 months

Primary outcome
Phase I: Incidence of dose limiting toxicities (DLTs) of [177Lu]-NeoB
Time frame: Within 42 days following the first administration of [177Lu]-NeoB
A dose-limiting toxicity (DLT) is defined as a clinically relevant adverse event or abnormal laboratory value not attributable to the disease or disease-related processes under investigation, considered possibly related to [177Lu]-NeoB that occurs within 42 days following the first administration of [177Lu]-NeoB (cycle 1) and meets any of the criteria listed in Table 6-4 (Criteria for defining dose-limiting toxicities).
Phase I: Determination of Maximum Tolerated Dose (MTD)/ Recommended phase two dose (RP2D) of [177Lu]-NeoB
Time frame: Within 42 days following the first administration of [177Lu]-NeoB
The maximum tolerated dose (MTD) and/or the recommended phase II dose (RP2D) of [177Lu]-NeoB will be identified: 1. MTD is defined as the lowest single dose at which 25% or more of the patients experienced a DLT during the first cycle (6 weeks). 2. RP2D is defined as the single dose level below the MTD. The number of cycles recommended for Phase II will be defined based on the cumulative dose toxicities reported during Phase I.
Phase IIa (Cohorts A, B and C): Individual clinical responses assessed by Response Evaluation Criteria In Solid Tumors (RECIST v1.1)
Time frame: 25 months

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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Phase I: Incidence of dose limiting toxicities (DLTs) of [177Lu]-NeoB (time frame: Within 42 days following the first administration of [177Lu]-NeoB). The study lists 7 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 NCT03872778, 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?
