Brief summary

First in Human (FIH) study to characterize the safety, tolerability, pharmacokinetics (PK), distribution, radiation dosimetry, and anti-tumor activity of \[177Lu\]-NeoB in patients with advanced solid tumors known to overexpress GRPR and with \[68Ga\]-NeoB lesion uptake.

Detailed description

This study was designed to establish whether the ligand NeoB, a high affinity antagonist for GRPR, could be used in a theragnostic approach for selection and therapy of GRPRexpressing malignancies: radiolabeled with (1) Gallium 68 (68Ga) to identify lesions and with (2) Lutetium-177 (177Lu) for the treatment of these lesions.

Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository. Post-menopausal women are allowed to participate in this study. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum Follicle-Stimulating Hormone (FSH) levels \> 40 mIU/mL \[for US only: and estradiol \< 20 pg/mL\] or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks prior to screening. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of child bearing potential. Sexually active males must use a condom during intercourse while taking the drug and for 6 months after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.

Design outcomes

Primary

MeasureTime frameDescription
Phase I: Incidence of dose limiting toxicities (DLTs) of [177Lu]-NeoBWithin 42 days following the first administration of [177Lu]-NeoBA 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]-NeoBWithin 42 days following the first administration of [177Lu]-NeoBThe 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.

Phase IIa (Cohorts A, B and C): Absorbed radiation doses of [177Lu]-NeoB in organs and tumor lesions6 weeksAbsorbed radiation doses in organs and tumor lesions will be summarized with descriptive statistics. Lesion number will be assigned by dosimetry expert.
Phase IIa (Cohorts A, B and C): Concentration of [177Lu]-NeoB in blood over time and derived PK parameters6 weeksVenous whole blood samples will be collected for activity-based pharmacokinetics characterization. Concentration of \[177Lu\]-NeoB will be listed and summarized using descriptive statistics.
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)15 monthsThe 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).
