Sound waves boost chemo to fight liver tumors in pancreatic cancer patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Men must consent to use at least one contraceptive precaution from the initiation of the study treatment until at least 3 months after the final dose of the investigational product Exclusion Criteria: 1. Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected treatment-related pulmonary toxicity within 28 days before screening 2.

Judged by the principal investigator (PI) or sub-investigators to be inappropriate for participation in this study 16. Known or suspected hypersensitivity reactions to NH002-related phospholipids or polyethylene glycol (PEG), including prior reactions to common PEG-containing products such as colonoscopy bowel preparations, and certain laxatives (e.g., Miralax) 17. Known or suspected hypersensitivity reactions to one or more of the ingredients of NH002, Definity, or other perflutren-containing echocardiographic contrast agent. 18. Clinically unstable cardiopulmonary conditions, including but not limited to obstructive lung disease, cardiac shunt abnormalities, or arteriovenous shunt abnormalities, considered not suitable for participation in the trial, in the judgment of the investigator \-
