About this trial
A Phase 2 multi-center, open-label, single arm study of nab-sirolimus in patients with well-differentiated neuroendocrine tumors (NETs) of the gastrointestinal tract, lung, or pancreas who have not received prior treatment with mTOR inhibitors
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with functional or non-functional, well-differentiated, locally advanced unresectable or metastatic NETs of the GI tract, lung, or pancreas who have received 2 or less prior lines of therapy excluding somatostatin analogs
the patient has been on a stable dose of an somatostatin analogs for ≥12 weeks and
the patient has experienced disease progression while on stable somatostatin analogs dose
Patients must have 1 or more measurable target lesions by RECIST v1.1
Disqualifiers
Prior treatment with mTOR inhibitors including nab-sirolimus
Patients with functional NETs who are experiencing uncontrolled symptoms attributed to hormones and other vasoactive substances secreted by the tumor
Patients with inactivating TSC1 or TSC2 alterations (based on tissue or liquid NGS)
Severe (Grade ≥3) ongoing infection requiring parenteral or oral anti-infective treatment, either ongoing or completed ≤7 days prior to enrollment
Trial design
Single group

DrugProspective phase 2 single arm, open-label, multi-institutional study to determine the efficacy and safety prospective of nab-sirolimus administered by IV infusion
Treatment groups
Trial outcomes
Primary outcomes
Efficacy of nab-sirolimus
Objective Response Rate (ORR), defined as the proportion of patients with best overall response (BOR) of confirmed partial response (PR) or complete response (CR) from the time of study treatment initiation until progression of disease (PD) as determined by the Investigator using RECIST v1.1
Secondary outcomes
Incidence and severity of treatment
Incidence and severity of treatment-emergent and treatment-related adverse events (AEs) as assessed by NCI CTCAE v5.0
Duration of response
Determined for patients with BOR of confirmed CR or PR defined as time from scan first showing response by RECIST v1.1 to PD or death
Disease control rate
BOR of confirmed CR or PR (either of any duration) or stable disease (SD) ≥12 weeks by RECISTv1.1 following study treatment initiation
Time to response
Time from first dose of study medication to initial measurement of CR or PR, where CR or PR is subsequently confirmed by RECIST v1.1
