CAMPFIRE: A Study of Ramucirumab (LY3009806) in Children and Young Adults With Desmoplastic Small Round Cell Tumor

Study Overview
=================
Brief Summary
-----------------
This study is being conducted to test the safety and efficacy of ramucirumab in combination with other chemotherapy in the treatment of relapsed, recurrent, or refractory desmoplastic small round cell tumor (DSRCT) in children and young adults. This trial is part of the CAMPFIRE master protocol (NCT05999994) which is a platform to accelerate the development of new treatments for pediatric and young adult participants with cancer. Your participation in this trial could last 12 months or longer, depending on how you and your tumor respond.

This prior treatment must include approved therapies for which they are eligible, unless the participant is not a suitable candidate for the approved therapy. Not be eligible for surgical resection at time of enrollment. Adequate cardiac function, defined as: Shortening fraction of ≥27% by echocardiogram, or ejection fraction of ≥50% by gated radionuclide study. Adequate blood pressure (BP) control, defined as: Participants ≥18 years: Controlled hypertension defined as systolic BP ≤150 millimeters of mercury (mmHg) or diastolic BP ≤90 mmHg where standard medical management is permitted. Please note that ≥2 serial BP readings should be obtained and averaged to determine baseline BP. Participants <18 years: A BP ≤95th percentile for age, height, and gender measured as described in National High Blood Pressure Education Program Working Group (NHBPEPWG) on High Blood Pressure in Children and Adolescents (2004), where standard medical management is permitted.

Adequate hematologic function, as defined as: Absolute neutrophil count (ANC): ≥750/microliters (µL) granulocyte-colony stimulating factor (G-CSF) permitted up to 48 hours prior. Participants with documented history of benign ethnic neutropenia or other conditions could be considered with a lower ANC after discussion with and approval from the Lilly clinical research physician or scientist. Platelets: ≥75,000/cubic millimeters. Platelet transfusion permitted up to 72 hours prior. Hemoglobin: ≥8 grams per deciliter (g/dL) (≥80 g/liter). Transfusions to increase the participant's hemoglobin level to at least 8 g/dL are permitted; however, study treatment must not begin until 7 days after the transfusion, and complete blood count criteria for eligibility are confirmed within 24 hr of first study dose. Adequate renal function, as defined as: Creatinine clearance or radioscope glomerular filtration rate (GFR) ≥60 milliliters/minute/meters squared OR serum creatinine meeting the following parameters: for participants ≥18 years of age serum creatinine ≤1.5×upper limit of normal (ULN); for participants <18 years of age, serum creatinine based on age/gender as follows: Age 1 to <2 years maximum serum creatinine 0.6, Age 2 to <6 years maximum serum creatinine 0.8, Age 6 to <10 years maximum serum creatinine 1.0, Age 10 to <13 years maximum serum creatinine 1.2, Age 13 to <16 years maximum serum creatinine 1.5 for males and 1.4 for females, Age 16 to <18 years maximum serum creatinine 1.7 for males and 1.4 for females. Urine protein meeting the following parameters: for participants ≥18 years of age: <2+ on dipstick or routine urinalysis. If urine dipstick or routine analysis indicates proteinuria ≥2+, then a 24-hour urine must be collected and must demonstrate <2 grams of protein in 24 hours to allow participation in the study. for participants <18 years of age: ≤30 milligrams per deciliter urine analysis or <2+ on dipstick. If urine dipstick or routine analysis indicates proteinuria ≥2+, then a 24-hour urine must be collected and must demonstrate <1 g of protein in 24 hours to allow participation in the study. Adequate liver function: Total bilirubin: ≤1.5×ULN. Except participants with document history of Gilbert Syndrome who must have a total bilirubin level of <3.0×ULN. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST): ≤2.5×ULN OR ≤5.0×ULN if the liver has tumor involvement. The participant has an adequate coagulation function as defined by International Normalized Ratio ≤1.5 or prothrombin time ≤1.5×ULN, and partial thromboplastin time ≤1.5×ULN if not receiving anticoagulation therapy. For participants receiving anticoagulants, exceptions to these coagulation parameters are allowed if they are within the intended or expected range for their therapeutic use. Participants must have no history of clinically significant active bleeding (defined as within 14 days of first dose of study drug) or pathological condition that carries a high risk of bleeding (for example, tumor involving major vessels or known esophageal varices). The participant has adequate hematologic and organ function ≤1 week (7 days) prior to first dose of study drug. Female participants of childbearing potential must have a negative urine or serum pregnancy test within 7 days prior to randomization. Male and female participants must agree to use highly effective contraception for the duration of the study and up to 3 months following the last dose of ramucirumab and vinorelbine, and 12 months following the last dose of cyclophosphamide in order to prevent pregnancy. Exclusion Criteria: Participants with severe and/or uncontrolled concurrent medical disease or psychiatric illness/social situation that in the opinion of the investigator could cause unacceptable safety risks or compromise compliance with the protocol. Participants who have active infections requiring therapy. Participants with an active fungal, bacterial, and/or known severe viral infection including, but not limited to, human immunodeficiency virus (HIV) or viral (A, B, or C) hepatitis (screening is not required).

Surgery: Participants who have had, or are planning to have, the following invasive procedures are not eligible: Major surgical procedure, laparoscopic procedure, or significant traumatic injury within 28 days prior to enrollment. Central line placement or subcutaneous port placement is not considered major surgery. Core biopsy, fine needle aspirate, and bone marrow biopsy/aspirate are not considered major surgeries. Surgical or other wounds must be adequately healed prior to enrollment. Bleeding and thrombosis: Participants with evidence of active bleeding or a history of significant (≥Grade 3) bleeding event within 3 months prior to enrollment are not eligible.

Participants who have a history of fistula, gastrointestinal (GI) ulcer or perforation, or intra-abdominal abscess within 3 months of study enrollment are not eligible. Participants with a history of hypertensive crisis or hypertensive encephalopathy within 6 months of study enrollment are not eligible. Participants who have non-healing wound, unhealed or incompletely healed fracture, or a compound (open) bone fracture at the time of enrollment are not eligible. Participants previously treated and progressed on combination cyclophosphamide and vinorelbine regimen. Participants who received combination as maintenance therapy, without progression, would be eligible. Participants with a known hypersensitivity to ramucirumab, cyclophosphamide, vinorelbine or any of the excipients of the medicinal products. Hepatic impairment: Severe liver cirrhosis Child-Pugh Class B (or worse). Cirrhosis with a history of hepatic encephalopathy. Clinically meaningful ascites resulting from cirrhosis and requiring ongoing treatment with diuretics and/or paracentesis. History of hepatorenal syndrome.
