A Clinical Study Evaluating a New Treatment Strategy for Patients With Advanced Pancreatic Cancer Who Have Not Received Prior Treatment for Advanced Disease. (NUMANTIA-2)

A Randomized Phase II Study of Priming Treatment With the Hedgehog Inhibitor NLM-001 Prior to Gemcitabine/Nab-Paclitaxel (GNab-P) plusBotensilimab and Balstilimab (Bot/Bal) Versus GNab-P in Patients With Previously Untreated Advanced Pancreatic Cancer (NUMANTIA-2)

Phase II, open label, randomized multicenter study to evaluate efficacy and safety of study treatment in previously untreated patients with advanced pancreatic cancer.

In the experimental arm, patients who discontinue chemotherapy for reasons other than disease progression may continue receiving the remaining study drugs (NLM-001, botensilimab and balstilimab) up to a maximum of 24 months, according to schedule.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To evaluate the response rate in each of the study arms, assessed according to iRECIST criteria, including the confirmation of progression to distinguish true progression from potential pseudoprogression.	Objective Response Rate (ORR): Complete Response (CR) + Partial Response (PR), according to iRECIST 1.1 criteria, according to investigator criteria. Suspected progression (including possible pseudoprogression due to immune-related effects or new lesions) must be confirmed with repeat imaging performed 4-8 weeks after the initial assessment before considering the patient as having true disease progression.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To evaluate safety profile and tolerability of study treatment according to NCI-CTCAE v 5.0 criteria.	Safety profile will be assessed according to NCI-CTCAE v 5.0 criteria. The number of patients experiencing each AE will be summarized by CTCAE grade.	12 months
To evaluate treatment efficacy according to progression free survival (PFS)	Progression Free Survival (PFS): PFS is defined as the time in months from the patient's randomization until patient progression according to iRECIST 1.1 criteria or death.	12 months
To evaluate treatment efficacy according to 6 months PFS	Progression Free Survival (PFS): PFS is defined as the time in months from the patient's randomization until patient progression according to iRECIST 1.1 criteria or death.	6 months
To evaluate treatment efficacy according todisease control rate (DCR)	Disease Control Rate (DCR): Complete Response (CR) + Partial Response (PR) + Stable Disease (SD) evaluated by iRECIST 1.1 criteria according to investigator criteria.	12 months
To evaluate treatment efficacy according to duration of response (DoR)	Duration of Response (DoR): DoR is defined as the time in months from the date of first documented objective response (complete response [CR] or partial response [PR], whichever is first) until the date of first documented disease progression or death from any cause, whichever occurs first.	12 months
To evaluate treatment efficacy according to duration of clinical benefit (DoCB)	Duration of Clinical Benefit (DoCB): DoCB is defined, for subjects achieving clinical benefit (complete response [CR], partial response [PR], or stable disease [SD] per iRECIST v1.1), as the time from the date of first documented evidence of clinical benefit (CR, PR, or SD) until the date of first documented radiographic disease progression or death from any cause, whichever occurs first.	12 months

To evaluate CA 19.9 levels during study treatment (Decrease > 50%)	Decrease in CA 19.9 levels > 50%. Responses based on levels of the tumor marker CA 19.9 will be calculated as the maximum percentage of change with respect to baseline in those patients with a baseline higher than 1.25 times the upper limit of normal in the local laboratory of each center.	12 months
To evaluate CA 19.9 levels during study treatment (Decrease > 75%)	Decrease in CA 19.9 levels > 75%. Responses based on levels of the tumor marker CA 19.9 will be calculated as the maximum percentage of change with respect to baseline in those patients with a baseline higher than 1.25 times the upper limit of normal in the local laboratory of each center.	12 months
