FluoGuide announces positive topline results

FluoGuide has announced results from a phase IIa trial of its lead product FG001 in lung cancer.

FG001 was shown to illuminate the majority of the patients’ lung tumors and was well tolerated in all patients. These results support further clinical development in this indication. FG001 was shown to light up lung cancer in 73% of the patients and was safe and well tolerated.

This marks the third cancer indication for which FG001 shows efficacy, underscoring its potential for broad applicability, states the company.

“We are excited that FG001 has been shown to light up tumors in lung cancer and that we have data showing its efficacy in three cancer indications, underscoring the broad applicability of our lead product. These results are encouraging for the continuation of clinical development in lung cancer and we are looking forward to further data from our FG001 trials in head-and-neck and aggressive brain cancer in the near future. We will prepare next steps for development of FG001, considering data from all these studies and potential partner interest, over the coming months. We look forward to bringing our promising product towards market, with the aim of improving surgery outcomes for cancer patients,” says Morten Albrechtsen, CEO of FluoGuide.

Further data in brain and head & neck cancers are expected in H2-2023


FG001 is a fluorophore targeting uPAR, which is a cancer specific target expressed extensively in most solid types of cancers. The fluorophore has the same spectral specifications as indocyanine green, which is already approved, and this means FG001 can be used on current imaging equipment without adaptation. It is injected into a patient’s vein prior to surgery and lights up the cancer during surgery, helping to guide the surgeon in removing all cancer while sparing healthy tissue.

A total of 15 patients with non-small cell lung cancer (NSCLC), undergoing lung surgery (lobectomy), completed the trial, with a gender distribution of 9 females and 6 males a weight range of 50-92 kg and age range of 50-83 years. The primary objective was to evaluate FG001 for the detection of NSCLC.

The efficacy of FG001 (as a tumor imaging agent) was examined by sensitivity verified by the contrast expressed as tumor-to-background ratio (TBR) showing that 11/15 (73%) patients had a clinically relevant TBR value. The TBR values were measured under conditions with varying amounts of lung tissue covering the tumors, thus attenuating the signal from FG001. If the tumors had been uncovered, the proportion lightening up would likely have been even higher.

The first lung cancer cohort (7 patients) received 36 mg administered in the evening before surgery. The second cohort (8 patients) received 36 mg administered 2 days prior to surgery. The ability of FG001 to illuminate the tumors was similar in the two cohorts, indicating a broad time window for administration of FG001.

FG001 was shown to be safe and well tolerated in all patients. The pharmacokinetic (PK) profile for FG001 was determined in lung cancer patients and the half-life (t1/2) was found to be comparable with that of aggressive brain cancer (high grade glioma).

A pilot project in lung cancer screening in Denmark

Today, lung cancer is typically diagnosed when the cancer already has spread being an important reason for its high mortality. Clinical trials have shown that screening programs increase the survival by identifying patients with lung cancer earlier. These trials have demonstrated that screening leads to increased number of patients diagnosed with early-stage cancer, and hence improving the survival for patients diagnosed with lung cancer. This is the motivation for implementing screening programs for patients at high risk of lung cancer. Accordingly, implementation of screening programs for lung cancer are underway in major countries like USA.

”I am pleased to see that the Ministry of Health has approved a pilot project in lung cancer screening in Denmark. The earlier the lung cancer is diagnosed, the better is the prognosis for patients” says René Horsleben Petersen, Professor and Chief Thoracic Surgeon at Rigshospitalet and Principal Investigator of the lung cancer study. “Early identification of lung cancer promotes precision surgery as an important factor in lung cancer treatment.”

FluoGuide expects enrollment of the last patient in its phase IIb trial of FG001 in aggressive brain cancer (high grade glioma) during the summer of 2023 and the topline result approximately 2 months after that. Interim results from the phase IIa trial of FG001 in head & neck cancer are expected in H1 2023.
