Unmet Needs for Second-Line SCLC Treatment DocePLUS:  rationale for use in SCLC Biodistribution favorable for pulmonary delivery Phase I potential efficacy signal in lung cancer (NSCLC) Single-Agent Chemotherapy with HYCAMTIN® Demonstrated activity in SCLC In randomized clinical trial, key endpoints (ORR, DoR, TTP, OS) were not statistically improved over CAV treatment Adverse reactions included neutropenia, anemia, and thrombocytopenia Difficult dosing schedule: 1.5 mg/m2 IV infusion over 30 minutes daily on days 1 to 5 of each 21-day cycle HYCAMTIN is a registered trademark of Novartis



DocePLUS™ Market Research In considering 10 solid tumors and 3 target product profiles, oncologists viewed SCLC as an attractive Phase 2 study indication Low cure rate, rapid progression, low survival Lack of effective treatment options For second-line, view current standard of care as toxic, inconvenient, and minimally efficacious Expect shorter trial and easier patient recruitment (relative) Oncologists also cited pancreatic cancer as an attractive target and described a high willingness to use DocePLUS™ if FDA-approved for this indication Limited treatment options Difficulties in achieving good results with new treatments Source:  PLUS THERAPEUTICS interviews of U.S. physicians and payers
