Lugano, Switzerland, Feb. 14 (Korea Bizwire) – Helsinn, the Swiss pharmaceutical group focused on building quality cancer care products, today announces that scientific abstracts have been accepted for oral presentation and one abstract for poster presentation at the World Congress of Cutaneous Lymphomas (WCCL) taking place from 12-14th February 2020 in Barcelona, Spain.
The first oral presentation, entitled “The PROVe study: real-world experience with chlormethine gel1 and other therapies in the treatment of mycosis-fungoides cutaneous T-cell lymphoma patients,” outlines results from the largest prospective, open label, single arm, multicenter observational study (NCT02296164), assessing treatment patterns and efficacy, safety, and health-related quality of life (HR-QoL) outcomes in 298 MF-CTCL patients treated with chlormethine gel and other therapies in a real-world setting in the US.
Two additional presentations, one oral presentation and one poster, explore preliminary data from the Mechlorethamine Induced Contact Dermatitis Avoidance Study (MIDAS), an ongoing, open-label investigator-initiated study (IIS) investigating the incidence and types of contact dermatitis (CD) following treatment with mechlorethamine/chlormethine gel in patients with MF-CTCL.
One last presentation reports outcomes of a retrospective analysis evaluating the association of patient volume with early discontinuation and overall treatment duration for clinicians prescribing standardized 0.016% gel formulation mechlorethamine.
In the EU clinical study for LEDAGA: a randomized-controlled trial (n=128 exposed to Ledaga for a median duration of 52 weeks), the most frequent adverse reactions were skin related: dermatitis (54.7%; e.g., skin irritation, erythema, rash, urticaria, skin-burning sensation, pain of the skin), pruritus (20.3%), skin infections (11.7%), skin ulceration and blistering (6.3%), and skin hyperpigmentation (5.5%). Cutaneous hypersensitivity reactions were reported in 2.3% of the treated patients.”
Dr. Silvia Sebastiani, Head of Medical Affairs at Helsinn, commented: “As further information emerges from the PROVe and MIDAS studies, we continue exploring the potential of Valchlor®/Ledaga® for the treatment of this rare skin disease. We remain committed to offering the highest quality in care for patients.”
Dr. Ellen J. Kim, University of Pennsylvania, Professor of Dermatology, Penn Cutaneous Lymphoma Program, PROVe principal investigator, said: “There remains a distinct lack of knowledge regarding this rare disease thus our observational PROVe study of nearly 300 patients provides valuable information to the medical community. The PROVe results confirm that mechlorethamine/chlormethine gel treatment is effective in the management of MF-CTCL.”

About Valchlor®
INDICATION
VALCHLOR® (mechlorethamine) gel is indicated for the topical treatment of Stage IA and IB mycosis fungoides-type cutaneous T-cell lymphoma (MF‑CTCL) in patients who have received prior skin-directed therapy.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
VALCHLOR is contraindicated in patients with known severe hypersensitivity to mechlorethamine. Hypersensitivity reactions, including anaphylaxis, have occurred with topical formulations of mechlorethamine.
WARNINGS AND PRECAUTIONS
- Mucosal or eye injury: Exposure of mucous membranes to mechlorethamine such as the oral mucosa or nasal mucosa causes pain, redness, and ulceration, which may be severe. Exposure of the eyes causes pain, burns, inflammation, photophobia, and blurred vision. Blindness and severe irreversible anterior eye injury may occur. Should eye exposure or mucosal contact occur, immediately irrigate for at least 15 minutes with copious amounts of water, followed by immediate medical consultation
- Secondary exposure: Avoid direct skin contact with VALCHLOR in individuals other than the patients due to risk of dermatitis, mucosal injury, and secondary cancers
- Dermatitis: Dermatitis may be moderately severe or severe. Monitor patients for redness, swelling, inflammation, itchiness, blisters, ulceration, and secondary skin infections. Stop treatment with VALCHLOR or reduce dose frequency
- Non‑melanoma skin cancer: Monitor patients during and after treatment with VALCHLOR
- Embryo‑fetal toxicity: May cause fetal harm. Women should avoid becoming pregnant while using VALCHLOR due to the potential hazard to the fetus. For nursing mothers, do not breastfeed during treatment with VALCHLOR
- Flammable gel: VALCHLOR is an alcohol‑based gel. Avoid fire, flame, and smoking until the gel has dried
ADVERSE REACTIONS
The most common adverse reactions (≥5%) were dermatitis (56%), pruritus (20%), bacterial skin infection (11%), skin ulceration or blistering (6%), and hyperpigmentation (5%). These reactions may be moderately severe or severe. Elderly patients aged 65 and older may be more susceptible. Depending on severity, treatment reduction, suspension, or discontinuation may be required.
USE IN SPECIFIC POPULATIONS
- Contraception: Females who are able to become pregnant, and males with female partners who are able to become pregnant, should use a barrier method of contraception to avoid direct exposure of reproductive organs to VALCHLOR
- Infertility: The reproductive effects of VALCHLOR have not been studied: however systemically administered mechlorethamine may impair fertility. The reversibility of the effect on fertility is unknown.
DOSING AND APPLICATION
VALCHLOR is for topical dermatologic use only. Apply a thin film of gel once daily to affected areas of the skin. VALCHLOR is a cytotoxic drug and special handling and disposal procedures should be followed during use. Caregivers must wear disposable nitrile gloves when applying VALCHLOR.

About Mycosis Fungoides
Mycosis fungoides (MF) accounts for almost 50% of all primary cutaneous lymphomas, a form of non-Hodgkin’s lymphoma. The cause of MF remains unknown and there are no curative treatments. MF has an indolent clinical course, slowly progressing from patches to thicker plaques and eventually to tumours over years or decades. Signs include rash, patch and plaques with severe itch. MF typically affects older adults (median age at diagnosis: 55-60 years) with male predominance.
