Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed informed consent form (ICF)
• Ability to comply with the study protocol as per the investigator's judgment
• Age ≥ 18 years at the time of signing the ICF
• Life expectancy ≥ 12 weeks
• Karnofsky performance status ≥ 70% or ECOG 0, -1 or 2
• Pathologically confirmed diagnosis of small cell lung cancer. Patients with a diagnosis of combined small cell lung cancer with other histologies may be considered for inclusion if the predominant histology is SCLC and only after discussion with the study PI. Patients with transformed SCLC from NSCLC are allowed on study after discussing with the MSKCC or JHU Study PI
• Radiographically documented progression of disease after prior treatment with a platinum doublet regimen. Patients who received a platinum doublet regimen in combination with immunotherapy are still eligible for the study.
• Measurable disease according to RECIST v1.1
• Adequate tissue sample available for both IHC testing of IHC testing of SLFN11 and H3K27me3 and molecular profiling (archived tissue block or 20 unstained slides). Tissue sample can be either from an initial pre-platinum-based chemotherapy sample OR from a repeat biopsy sample after progression on platinum-based chemotherapy.
• Concurrent consent to the appropriate biospecimen research protocols at MSKCC (#06-107 Storage and Research Use of Human Biospecimens) and at JHU.
• Adequate hematologic and end-organ function, as defined by the following laboratory test results obtained within 14 days prior to initiation of study treatment:
• °Adequate bone marrow function as defined by:
• Absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L (1500/µL) without granulocyte colony-stimulating factor support within 2 weeks prior to starting study therapy
• Hemoglobin ≥ 9 g/dL (transfusions to meet this criterion are allowed)
• Platelets ≥ 150 x 10\^9/L without transfusion
• Adequate renal function as defined by:
• °Creatinine clearance ≥ 50 mL/min as calculated using the modified Cockcroft-Gault equation or Modification of Diet in Renal Disease (MDRD) formula OR serum creatinine ≤1.5 x ULN
• Adequate hepatic function as defined by:
• AST, ALT, and alkaline phosphatase (ALP) ≤ 3 x ULN with the following exceptions
• Patients with documented liver metastases: AST, ALT and ALP ≤ 5 x ULN
• Total bilirubin ≤ 2.0 mg/dL
• For patients not receiving therapeutic anticoagulation:
• stable anticoagulant regimen
• INR ≤ 1.5 x ULN
• aPTT ≤ 1.5 x ULN

You may not qualify if…

• Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of study procedures.
• Untreated CNS metastases
• Patients with treated CNS metastases are allowed on the study as long as their clinical symptoms are adequately controlled and the daily dose of steroid use is equivalent to or less than 10 mg of prednisone.
• Is receiving concomitant treatment with a strong inhibitor or inducer of CYP3A4/5 within 7 days of first receipt of DS-3201b.
• °Consumption of herbs/fruits that may have an influence on PK of DS-3201b (strong CYP3A inhibitors or inducers) such as St. John's wort, star fruit, Seville orange or Seville orange-containing foods and beverages, grapefruit or grapefruit-containing food or beverages should be avoided from 14 days prior to the start of the study and throughout the entire study.
• Prior exposure to DS-3201b or other inhibitors of enhancer of zeste homologue-2 (EZH2)
• Prior exposure to topoisomerase inhibitors, including topotecan and irinotecan
• Refractory nausea and vomiting, malabsorption, biliary shunt, significant bowel resection, or any other condition that significantly affects gut motility or absorption and would preclude adequate absorption of DS-3201b in the opinion of the treating physician and/or PI.
• Currently receiving anticancer therapies or who have received anticancer therapies within 2 weeks prior to the initiation of study treatment. Anticancer therapies include chemotherapy, biologics, targeted therapies, immunologics, or other investigational therapy.
• Currently receiving radiation therapy, or who have received radiation within 2 weeks prior to the initiation of study treatment.
• Patients who have not recovered to Grade ≤1 or baseline from adverse events due to prior anticancer therapy.
• Patients who have had a major surgery or significant traumatic injury within 4 weeks of start of study drug, patients who have not recovered from the side effects of any major surgery (defined as requiring general anesthesia).
• NOTE: Procedures such as a percutaneous biopsy, pleural catheter insertion, placement of a central venous catheter or other minor procedures are permitted.
• Uncontrolled or significant cardiovascular disease, including the following:
• Evidence of prolongation of QT/QTc interval (e.g., repeated episodes of QT corrected for heart rate using Fridericia's method [QTcF] >450 ms for men and >470 ms for females) ECG from 12-lead electrocardiogram for measurement of corrected QT interval according to the Fridericia formula: electrocardiogram must be registered at rest. For any EKG assessment, if the initial EKG shows a prolonged QTc, then two additional EKGs will be obtained, resulting in three specimens taken after a space of
• 1 minute, and the mean of the 3 EKGs will be used to determine eligibility and for grading of TRAEs.
• Diagnosed or suspected long QT syndrome, or known family history of long QT syndrome
• History of clinically relevant ventricular arrhythmias, such as ventricular tachycardia, ventricular fibrillation, or Torsade de Pointes
• Uncontrolled arrhythmia (subjects with asymptomatic, controllable atrial fibrillation may be enrolled), or asymptomatic persistent ventricular tachycardia
• Subject has clinically relevant bradycardia of <50 bpm unless the subject has a pacemaker
• History of second- or third-degree heart block. Candidates with a history of heart block may be eligible if they currently have pacemakers, and have no history of fainting or clinically relevant arrhythmia with pacemakers, within 6 months prior to Screening
• Myocardial infarction within 6 months prior to Screening
• Angioplasty or stent graft implantation within 6 months prior to Screening
• Uncontrolled angina pectoris within 6 months prior to Screening
• New York Heart Association (NYHA) Class 3 or 4 congestive heart failure
