A Clinical Trial of Pulsed-dye Laser Versus Timolol Topical Solution Versus Observation on the Growth of Hemangioma in Newborn
Purpose
The purpose of this study is to find out if pulsed dye laser treatment or timolol maleate 0.5% gel can help infants who have a hemangioma. The investigators also want to find out if pulsed dye laser treatment and timolol maleate 0.5% gel are safe to use without causing too many side effects. Hemangioma is a common type of birthmark. These birthmarks happen when many new blood vessels grow in a specific area on the skin. Blood vessels are tiny tubes that carry blood through the body. No one knows what causes blood vessels to group together. Most birthmarks don't hurt at all and they usually aren't a sign of any kind of illness. Lots of newborns have these birthmarks on their bodies, like between the eyebrows. These birthmarks usually disappear within the first few months to years of life. These birthmarks tend to disappear spontaneously. Most hemangiomas are not treated unless the hemangioma threatens the child's health, which occurs in about 1 in 3 children with hemagiomas. Pulsed dye laser is widely used in children, and is approved by the U.S. Food and Drug Administration (FDA) for treating hemangioma. The FDA has approved timolol maleate to treat glaucoma in adults, but the FDA has not approved timolol maleate to treat hemangiomas in children. About 7 infants with hemangiomas have received timolol maleate. The results so far show that timolol maleate may be helpful and safe in treating hemangiomas in infants. An important question being tested in this study is whether pulsed-dye laser or timolol maleate can prevent hemangioma from growing when used very early after birth.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Topical Timolol |
After verification of eligibility criteria and obtaining informed consent of parent/guardian, infants randomized to the timolol arm will receive twice daily topical application of a physician-specified amount of timolol maleate 0.5% ophthalmic solution (hereby referred to as topical timolol) for up to six months. |
|
|
No Intervention Observation |
After verification of eligibility criteria and obtaining informed consent of parent/guardian, infants randomized to the observation arm will be followed at study visits according to protocol. |
|
|
Experimental Pulsed Dye Laser |
After verification of eligibility criteria and obtaining informed consent of parent/guardian, infants randomized to the pulsed dye laser arm will receive a series of six weekly to semi-weekly laser treatments treatments for up to 6 treatments with potential for reduced number of treatments if the hemangioma completely resolves. A 595-nm pulsed-dye laser (PDL, V-beam Perfecta, Candela Corp, Wayland, MA) with a dynamic cooling device (DCD) will be utilized for all treatments. This device is cleared by the FDA for clinical treatment of vascular lesions. |

Detailed Description
Hemangiomas affect 5-10% of all children born in the United States and up to 20% of premature infants, with a higher incidence in girls. Most infantile hemangiomas (IHs) appear within a few weeks of birth, grow rapidly for months to years and eventually involute. "Benign neglect" (no treatment) is therefore recommended by most pediatricians. However, about 1/3 of cases (2-3% of all children born in the US) eventually require medical or surgical interventions for hemangiomas due to blocked vision, problems with breathing, feeding, pain, ulceration, infection, profuse bleeding or disfigurement. None of the interventions are benign. Occasionally, hemangiomas may be fatal. The broad objective of this study is to prevent injury and disfigurement of millions of children per year by developing a very safe, effective, and non-invasive treatment that inhibits the growth of cutaneous hemangiomas in newborns. Historically, pulsed dye laser has been known to bea very effective and safe treatment for hemangiomas; however, this treatment modality has not been studied for the treatment of very early hemangiomas. Recently, systemic beta-blockade with propanolol has also shown remarkable results in treating threatening hemangiomas. However, systemic propanolol is not benign and requires inpatient monitoring for cardiac side effects. Topical beta-blocker has been demonstrated in a case report to prevent the growth of infantile eyelid hemangioma. We propose a prospective, single blinded, randomized study of pulsed dye laser (PDL) and topical beta-blocker solution (timolol maleate ophthalmic gel forming solution) in the treatment of very early hemangiomas. Specifically the efficacy, side effects and outcome of PDL and timolol will be compared with no treatment, the present standard of care for early stage hemangiomas. The extent to which early laser treatment or topical timolol treatment prevents tumor growth and the need for future medical or surgical treatments will be determined. Infants will be recruited from the pediatric and neonatal practices at Massachusetts General Hospital, and randomized to receive either: (1) a series of weekly to semi-weekly laser treatments, (2) twice daily topical application of timolol ophthalmic gel-forming solution for six weeks, or (3) no treatment. Hemangiomas will be assessed clinically and with digital photography for serial repeated measures of hemangioma size at each study visit. A panel of blinded evaluators will also provide assessment from photographs. Response, side effects and need for additional treatments will be recorded for up to 2 years after PDL and topical timolol treatment. This clinical trial fills a large gap in evidence-based medical therapy for IHs. If indeed early laser treatment of hemangiomas with PDL or topical timolol, both relatively harmless treatments, can eliminate the potential for complications by treating hemangiomas prior to the growth phase, then this trial would present an attractive solution for the problem of when and how to treat.
