About

This is a Phase 2, multicenter, open-label, multi-cohort study to assess safety and efficacy of CC-90011 in combination with nivolumab in subjects with small cell lung cancer or squamous non-small cell lung cancer who have progressed after 1 or 2 lines of therapies.

The primary objectives of the study are to evaluate the overall response rate of subjects treated with CC-90011 in combination with nivolumab in three cohorts:

Cohort A: SCLC in ICI naïve subjects
Cohort B: SCLC in ICI progressor subjects
Cohort C: sqNSCLC in ICI progressor subjects Overall response rate is defined as the proportion of subjects in the treated population who had complete response (CR) or partial response (PR) as assessed by Investigator review per RECIST v1.1.

In Cohort A, expected ORR for nivolumab monotherapy is 14% while target ORR is 30%. To achieve at least 80% power with one-sided type 1 error 0.1, 39 subjects will be enrolled according to a 2-stage group sequential design based on a binomial test. In stage 1, 12 subjects will be enrolled and treated with CC-90011 in combination with nivolumab. If there are 2 or more subjects responding, Cohort A will continue to enroll an additional 27 subjects. If 1 or less subjects respond in stage 1, Cohort A will stop for futility.

In Cohort B and C, expected ORR for nivolumab monotherapy is 5% while target ORR is 15%. To achieve at least 80% power with one-sided type 1 error 0.1, 48 subjects will be enrolled according to a 2-stage group sequential design based on a binomial test. In stage 1, 14 subjects will be enrolled and treated with CC-90011 in combination with nivolumab. If there are 1 or more subjects responding, Cohort B and C will continue to enroll an additional 34 subjects each. If 0 subjects respond in stage 1, Cohort B and C will stop for futility.

Inclusion criteria

Subjects must satisfy the following criteria to be enrolled in the study:

Subject is ≥ 18 years of age at the time of signing the informed consent form (ICF).
Subject with histological or cytological confirmation of extensive stage Small Cell Lung Cancer (ES SCLC) or Stage IIIb or IV squamous Non-Small Cell Lung Cancer (sqNSCLC)
Subject has received 1 or 2 prior lines of therapies, defined as:
1. Cohort A (SCLC, Immune Checkpoint Inhibitor naïve):
  - At least 1 prior treatment including a platinum-based chemotherapy doublet
  - A minimum of 3 cycles of platinum-based chemotherapy in first line treatment, unless stopped at 2 cycles due to treatment-related toxicity
2. Cohort B (SCLC, ICI progressors):
  - At least 1 prior first or second line treatment includes an ICI
  - If treatment includes an ICI as maintenance therapy, at least 1 cycle of ICI in maintenance should have been completed
  - At least 1 prior treatment including a platinum-based chemotherapy doublet
  - A minimum of 3 cycles of platinum-based chemotherapy, with or without ICI, in first line treatment, unless stopped at 2 cycles due to treatment-related toxicity
  - Subject must have progressed during ICI therapy, defined as unequivocal progression on or within 3 months of the last dose of ICI therapy (if no subsequent therapy)
3. Cohort C (sqNSCLC, ICI progressors):
  - At least 1 prior first or second line treatment includes an ICI
  - If treatment includes an ICI as maintenance therapy, at least 1 cycle of ICI in maintenance should have been completed
  - At least 1 prior treatment including a platinum-based chemotherapy doublet
  - A minimum of 3 cycles of platinum-based chemotherapy, with or without an ICI, in first line treatment, unless stopped at 2 cycles due to treatment-related toxicity
  - Subject must have progressed during ICI therapy, defined as unequivocal progression on or within 3 months of the last dose of ICI therapy (if no subsequent therapy)
Subject has progressed at the last line of therapy.
Subject has a measurable disease defined by RECIST v1.1.
Subject agrees to provide a tumor biopsy from primary or metastatic site prior to first dose and at a pre-specified timepoint during treatment. Core biopsy is required however, in the event a core biopsy may not otherwise be feasible in the opinion of the treating physician, an endobronchial ultrasound-guided fine needle aspirate [EBUS-FNA]) biopsy, using the largest gauge needle, may be performed instead.
Subject has ECOG Performance Status of 0 to 1.
Subject must have the following laboratory values:
1. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
2. Hemoglobin (Hgb) ≥ 9 g/dL (one-time blood transfusion is allowed)
3. Platelet (Plt) Count ≥ 150 x 109/L
4. White blood cells (WBC) ≥ 2 x 109L
5. Serum AST/serum glutamic oxaloacetic transaminase (SGOT) or ALT/serum glutamic pyruvic transaminase (SGPT) ≤ 3 x upper limit of normal (ULN) or ≤ 5 x ULN if presence of liver metastases
6. Total serum bilirubin ≤ 1.5 x ULN (≤ 3 x ULN, if Gilbert's syndrome or if indirect bilirubin concentrations are suggestive of extrahepatic source of the elevation)
7. Creatinine clearance (CrCl) ≥ 60 mL/minute based on Cockcroft-Gault or modification of diet in renal disease (MDRD) or ≥ 60 mL/min/1.73 m2

Exclusion criteria

The presence of any of the following will exclude a subject from enrollment:
