Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Kaposi sarcoma (KS) lesions are initiated by endothelial cells infected with KS herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8). Lesion progression is driven by abnormal angiogenesis, chronic inflammation, and uncontrolled cell proliferation. KS remains one of the most commonly diagnosed cancers in many African countries where economic constraints prevent successful treatment in most patients. Treatment outcomes in developed countries are also often unsatisfactory in HIV positive patients despite good virological and immunological responses to antiretroviral therapy. Therefore, identification of new oral, safe treatment options for treatment of KS remains a research priority. Given the known anti-angiogenic properties and based on the treatment response with other benign vascular lesions such as infantile hemangioma, propranolol is a good candidate for the treatment of KS. The hypothesis of this study is that treating patients with Kaposi sarcoma with propranolol will result in an overall response rate (complete response rate plus partial response rate) of at least 45%, and that propranolol will be safe and well tolerated in this patient population.

Inclusion Criteria	Exclusion Criteria
* Biopsy proven Kaposi Sarcoma that is measurable with a millimeter ruler. Patients presenting for both front-line therapy and subsequent-line therapy will be considered. * Must have two lesions greater than or equal to 4 mm x 4 mm, or one lesion greater than or equal to 8 mm x 8 mm, that are accessible for 4-mm punch biopsy. The patient must have at least 5 more lesions in addition to the lesion(s) being biopsied. * At least 18 years of age. * Weight ≥40 kg * ECOG performance status ≤ 2 * Meets the appropriate HIV-related criteria: * If HIV positive, patient must be on antiretroviral therapy (ART) that conforms to local standards of care for at least 12 weeks. HIV positive patients will not be excluded based on CD4 count or HIV viral load. * If on ART 12 to 24 weeks, must show evidence of KS progression requiring further systemic treatment. * If on ART for \> 24 weeks, must show no evidence of regression in the last 8 weeks. * If HIV negative, must not show evidence of improvement in the 12 weeks prior to enrollment. * Propranolol is US FDA pregnancy category C. For this reason, women of childbearing potential must agree to use adequate contraception prior to study entry, for the duration of study participation, and for one month after completion of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, s/e must inform her treating physician immediately. * Able to take an oral pill. * Ability to understand and willingness to sign an IRB approved written informed consent document.	* Visceral disease causing functional impairment. * Urgently clinically indicated for immediate cytotoxic chemotherapy. Patients who have received cytotoxic chemotherapy \> 4 weeks prior to screening are eligible. * Prior or concurrent malignancy whose natural history has the potential to interfere with the safety or efficacy assessment of the investigational regimen. Patients with prior or concurrent malignancy that does NOT meet that definition are eligible for this trial * Currently taking beta-andrenergic antagonist(s) for other indications. Prior use is allowed if the last dose of the beta-andrenergic antagonist is ≥ 5 half-lives of the agent prior to Day -7. * Currently receiving concurrent treatment with an anticancer therapy. Patients must not have received any anticancer therapies within 4 weeks prior to receiving the first dose of propranolol. * Currently receiving any other investigational agents. * A history of allergic reactions or hypersensitivity attributed to compounds of similar chemical or biologic composition to propranolol. * History of asthma or current diagnosis of obstructive airway disease such as asthma, COPD, or bronchiolitis. * History of diabetes mellitus, as defined by any of the following: A random blood glucose value of at least 200 mg/dL in the presence of hyperglycemia symptoms (weight loss, blurry vision, thirst, polyuria), fasting plasma glucose value of at least 126 mg/dL, A1c value of at least 6.5%, or two hour plasma glucose value of at least 200 mg/dL during a 75 g oral glucose tolerance test. * History of uncompensated heart failure, severe sinus bradycardia, sick sinus syndrome, or heart block greater than first degree. * History of hypotension (systolic blood pressure \<90 mmHg or mean arterial pressure \<65 mmHg) or orthostasis (\>20 mmHg fall in systolic pressure or \>10 mmHg fall in diastolic pressure with standing). (Isolated instances of hypotension may not be exclusionary after discussion with PI.) * Shortness of breath, hemoptysis, or moderate/severe cough not attributable to causes other than KS. * Bleeding from the mouth or rectum not attributable to causes other than KS. * Uncontrolled intercurrent illness including, but not limited to: ongoing clinically significant active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia. * Concern for KSHV inflammatory cytokine syndrome. * Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 21 days of study entry. * Evidence of chronic hepatitis B virus (HBV) that is detectable on suppressive therapy. Patients with evidence of chronic HBV infection with undetectable HBV viral load on suppressive therapy are eligible. HBV testing not required in the absence of known history of infection. * History of hepatitis C virus (HCV) infection that has not been cured or that has a detectable viral load. Patients with a history of HCV that has been treated and cured are eligible. Patients with HCV infection who are currently on treatment and have an undetectable HCV viral load are eligible. HCV testing not required in the absence of known history of infection.
