ImmunityBio Announces Results of Phase 2 Metastatic Pancreatic Cancer Trial at ASCO GI With Median Overall Survival of 6.3 Months in Patients With Third-Line Disease, More Than Doubling Historical Survival - Seite 2

QUILT 88 is an open-label study to evaluate the safety and efficacy of the Nant Cancer Vaccine, comprising ImmunityBio’s IL-15 receptor agonist Anktiva (N-803), its off-the-shelf targeted natural killer cells (PD-L1 t-haNK), and aldoxorubicin, an albumin-modulated agent, plus low-dose chemotherapy. This combination Nant Cancer Vaccine is randomized against standard-of-care high-dose chemotherapy for first- and second-line treatment; the third-line or greater cohort, with an original target of 50 patients, is a single arm with the primary endpoint of overall survival.

QUILT-88 Study Details

This Phase 2, randomized, three-cohort, open-label study will evaluate the comparative efficacy and overall safety of standard-of-care chemotherapy versus low-dose chemotherapy in combination with PD-L1 t-haNK, Anktiva (N-803), and aldoxorubicin in subjects with locally advanced or metastatic pancreatic cancer (NCT04390399). Each treatment setting, as well as each first- and second-line or later maintenance treatment, will be evaluated independently as Cohorts A, B, and C, respectively, with Cohorts A and B having independent experimental and control arms. The study is expected to enroll 328 subjects across all three cohorts giving effect to the expanded enrollment of Cohort C (63 of 80 participants are currently enrolled in Cohort C, third-line or greater). The primary objective of Cohorts A and B is progression-free survival (PFS) per RECIST V1.1, and the objective of Cohort C is overall survival (OS). Secondary objectives include initial safety and additional efficacy measures, including overall response rate (ORR), complete response (CR) rate, durability of response (DoR), disease control rate (DCR), and overall survival (OS).

Currently, three trial sites have been activated: Hoag Memorial Hospital Presbyterian in Orange County, Calif., The Chan Soon-Shiong Institute for Medicine in Los Angeles County, Calif., and Avera McKennan Hospital and University Health Center in Sioux Falls, South Dakota, which serves patients in the tri-state area (Iowa, Nebraska and South Dakota).

About ImmunityBio

ImmunityBio is a leading late-clinical-stage immunotherapy company developing next-generation therapies that drive immunogenic mechanisms for defeating cancers and infectious diseases. The company’s broad immunotherapy and cell therapy platforms—including Antibody cytokine fusion proteins, synthetic immunomodulators, vaccine technologies (hAd5 viral vector, mRNA, recombinant protein, and adjuvant), and genetically-modified, off-the-shelf natural killer cells (autologous and allogenic cytokine-enhanced memory NK cells)—activate both the innate (natural killer cell and macrophage) and adaptive (T cell) immune systems to create long-term “immunological memory.”
