Lung Cancer, SCLC

Brief summary

This is an open-label Phase I/II study, with a dose escalation part (Phase I) and a single-arm part (Phase II), in patients with recurrent SCLC who progressed after first-line platinum-based chemotherapy and who are candidates for second line therapy. No PK evaluation is planned in this study as nivolumab and ipilimumab are unlikely to alter plinabulin's PK, since the route of excretion is different.

Detailed description

This is an open-label Phase I/II study, with a dose escalation part (Phase I) and a single arm part (Phase II), in patients with recurrent SCLC. In the Phase I part, patients will receive plinabulin at escalating doses in combination with nivolumab and ipilimumab. Doses of study drug will be administered as intravenous (IV) infusions in 21 day cycles. Patients will receive all study drugs on Day 1 of each cycle. After 4 treatment cycles, ipilimumab is stopped and patients continue treatment with nivolumab and plinabulin every 2 weeks (maintenance period) or until disease progression, development of unacceptable toxicity or one of the protocol-defined reasons for treatment discontinuation occurs. At least 3 patients will be enrolled in each cohort, starting at 20 mg/m2 of plinabulin. The dose of plinabulin will be escalated in sequential patient cohorts after the safety data from the first cycle is reviewed. Thereafter the dose of plinabulin will be escalated to 30 mg/m2, provided that dose-limiting toxicities (DLTs) are not observed per the specified criteria, until the RP2D is determined. In the Phase II part, up to 26 patients will be treated with the triple combination of plinabulin (at RP2D) + nivolumab + ipilimumab. Patients will continue treatment until disease progression, development of unacceptable toxicity or one of the protocol-defined reasons for treatment discontinuation occurs.

Interventions

DRUGNivolumab

A fully human immunoglobulin (Ig) G4 monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed death-1 (PD-1,PCD-1,) with immune checkpoint inhibitory and antineoplastic activities.

Plinabulin (BPI-2358) is a synthetic, low molecular weight, new chemical entity originally developed by Nereus Pharmaceuticals, Inc., and now by BeyondSpring Pharmaceuticals, Inc. It belongs to the diketopiperazine class of compounds with a chemical name 2, 5-piperazinedione, 3-\[\[5-(1,1-dimethylethyl)-1H-imidazol-4-yl\[methylene\]-6-(phenylmethylene)-, (3Z,6Z) (trivial name t-butyl-dehydrophenylahistin).

DRUGIpilimumab

Ipilimumab is a monoclonal antibody that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.

Inclusion criteria

The patients must satisfy all of the following inclusion/

Exclusion criteria

in order to be eligible for the study: * Must have signed and dated written informed consent form in accordance with regulatory and institutional guidelines. * Males and females aged \>18 years at time of consent. * Histological or cytological confirmed extensive-stage SCLC * Patients who progressed after at least 1 platinum-based chemotherapy regimen. Patients with platinum resistance (defined as recurrence or progression of disease within 90 days of completion of the platinum-based regimen) are eligible. For phase II, patients also must have been treated with at least one prior line of PD-1/PD-L1 therapy. * Measurable disease according to RECIST v1.1 (Section 8) obtained by imaging within 28 days prior to study registration. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 14 days before registration and minimum life expectancy of at least 12 weeks. * Treatment to be initiated at least 2 weeks since last dose of prior systemic anticancer therapy (chemotherapy, radiation, and/or surgery. * Recovery to grade 1 of any clinically significant toxicity (excluding alopecia, grade 2 fatigue, vitiligo, endocrinopathies on stable replacement therapy) prior to initiation of study drugs. * Female patients of childbearing potential have a negative pregnancy test at baseline. Females of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti estrogens, or ovarian suppression. * Women of childbearing potential (i.e., menstruating women) must have a negative urine pregnancy test (positive urine tests are to be confirmed by serum test) documented within 14 days of study registration and within the 24-hour period prior to the first dose of study drug. * Sexually active women of childbearing potential enrolled in the study must agree to use 2 forms of accepted methods of contraception during the course of the study and for 23 weeks after their last dose of study drug. Effective birth control includes (a) intrauterine device plus 1 barrier method; (b) on stable doses of hormonal contraception for at least 3 months (e.g., oral, injectable, implant, transdermal) plus one barrier method; (c) 2 barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm); or (d) a vasectomized partner. * For male patients who are sexually active and who are partners of premenopausal women: agreement to use 2 forms of contraception as in criterion 9b above during the treatment period and for 31 weeks after the last dose of study drug. * Adequate laboratory values. * Absolute neutrophil count ≥1,000/µL * Platelet count ≥100,000/µL * Hemoglobin ≥9.0 g/dL * Total bilirubin ≤1.5 x upper limit of normal (ULN) or ≤3 x ULN for subjects with Gilbert's disease * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 x ULN (≤5 x ULN if evidence of hepatic involvement by malignant disease) * Creatinine ≤ 1.5 x ULN or estimated glomerular filtration rate (eGFR) ≥40 mL/min/1.73m2 * Lipase and Amylase ≤1.5 x ULN. Subjects with Lipase \>1.5 x ULN may enroll if there are neither clinical nor radiographic signs of a pancreatitis.
