Meet Our TEAM
We are a group of scientists with a vision to get the affordable PDT treatment available to every patient who needs it.
How it All Started…
As the mother of PDT, Professor Hasan has always wanted to apply PDT for oral cancers in her home country, India, where oral cancer is a pandemic. Finally, in 2014, she and Professor Celli received a $4 million NIH grant to develop a low-cost technology for resource-limited settings. They did a 30-patient clinical trial for early oral cancers at Aligarh Muslim University. The results were fantastic: 73% one-time complete curing rate without much side effect except being photosensitive for 24 hours. In 2022, they received another $4 million grant for a second clinical trial in India with more patients.

"Over 1,500 patients (a mixture of presentations including primary, recurrent, and metastatic lesions) have been treated with PDT using Photofrin, HPD, ALA, or Foscan for head and neck cancers. The predominant histology is squamous cell carcinoma, but other histologies treated include mucosal melanoma, Kaposi’s sarcoma, adenocarcinoma, metastatic breast carcinoma, and adenoid cystic carcinoma."
