Novartis Pharmaceuticals180 enrolled

Overview

The purpose of this study is to evaluate the safety, tolerability, dosimetry and preliminary efficacy of \[177Lu\]Lu-DFC413 and safety and imaging properties of \[68Ga\]Ga-NNS309 in patients aged ≥ 18 years with solid tumors

GCJ904A12101 is first-in-human (FIH), phase I, open label study that consists of a dose escalation part followed by a dose expansion part. In both parts of the study, patients will initially be imaged with a 68Ga-NNS309 positron emission tomography (PET)/ computed tomography (CT) or PET/magnetic resonance imaging (MRI) scan and will be evaluated for eligibility for 177Lu-DFC413 treatment. Patients eligible for treatment will receive 177Lu-DFC413. In the escalation part, different doses of 177Lu-DFC413 will be tested to assess its safety, tolerability, and dosimetry and identify the recommended radioactive administered dose(s) (RD(s)) for further evaluation. The expansion will include arms based on tumor type. The end of study will occur when all patients per disease group in the expansion part have completed the follow-up for disease progression or discontinued from the study for any reason, and all patients have completed treatment and the long-term follow-up period.

Outcomes

Primary Outcomes

Incidence and severity of dose limiting toxicities of 177Lu-DFC413

A dose limiting toxicity (DLT) is defined as any adverse event or abnormal laboratory value of CTCAE (version 5.0) Grade 3 or higher that occurs within the DLT evaluation period and that is not primarily related to disease, disease progression, intercurrent illness, or concomitant medications with a few exceptions defined in the study protocol. Other clinically significant toxicities may be considered to be DLTs, even if not Grade 3 or higher.

Time frame: Within first treatment cycle, up to maximum 6 weeks

Incidence and severity of adverse events and serious adverse events of 177Lu-DFC413

The distribution of adverse events will be done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs) and Serious Adverse Event (TESAEs) and through the monitoring of relevant clinical and laboratory safety parameters.

Time frame: From study treatment start up to approximately 42 months

Dose modifications for 177Lu-DFC413

Dose modifications (dose interruptions and reductions) for 177Lu-DFC413 will be assessed and summarized using descriptive statistics. The number of patients with dose modification and the reasons will be summarized by treatment groups.

Time frame: From study treatment start until last dose of study treatment, assessed up to approximately 24 weeks

Dose intensity for 177Lu-DFC413

Dose intensity for 177Lu-DFC413 will be assessed and summarized using descriptive statistics. Dose intensity is computed as the ratio of actual cumulative dose received and actual duration of exposure.

Time frame: From study treatment start until last dose of study treatment, assessed up to approximately 24 weeks

Secondary Outcomes

Overall response rate (ORR)

ORR is defined as the proportion of patients with a BOR of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 guidelines.

Time frame: From study treatment start up to 6 months

Duration of Response (DOR)

DOR is the time between the first documented response (CR or PR) and the date of progression according to RECIST v1.1 guidelines, or death due to any cause.

Time frame: From study treatment start up to 6 months

Disease control rate (DCR)

DCR is defined as the proportion of patients with a BOR of CR, PR or stable disease according to RECIST v1.1 guidelines.

Time frame: From study treatment start up to 6 months

Progression free survival (PFS)

PFS is defined as the time from the date of start of treatment to the date of the first documented progression according to RECIST v1.1 guidelines or death due to any cause.
