Pipeline

SurgiMab is currently working on the development of two products, with ongoing external collaborations on additional candidates.

SGM-101 is a tumor-specific antibody conjugated to a near-infrared fluorochrome. It selectively binds a specific marker overexpressed in gastrointestinal and breast tumors.

SGM-201 similarly targets ovarian cancer. Both allow surgeons to visualize tumors in real-time with a near-infrared camera, helping them to perform more radical cytoreductive surgery, thus automatically improving surgical outcomes.

Clinical development

80% of cancer patients are treated with surgery as first intention. Up to 40% relapse within 2 years because surgeons left some tumor in place, due to their inability to clearly distinguish tumor from normal tissue with only vision or palpation.

SGM-101 safety was demonstrated in a first-in-human study in Montpellier Cancer Institute.

  • Title : Phase I Study assessing safety of SGM-101, a fluorochrome-labeled anti-CEA agent monoclonal antibody … in patients with peritoneal carcinomatosis from CEA-expressing digestive cancer.
  • Primary outcome : Maximum Tolerated Dose, Recommended phase II dose
  • Secondary outcome : Safety profile, Pharmacokinetic profile

With satisfactory safety results, SurgiMab decided to evaluate SGM-101 efficacy in pancreatic and  rectal cancers, as surgery is the cornerstone of the treatment for these patients. An exploratory patient group, consisting of patients with a recurrence or metastasis of colorectal cancer and rising CEA- levels was also included to the trial.

Clinical trials in progress

SGM-101 is currently tested in an ongoing trial in LUMC (Netherlands)

  • Title : Study on the detection of cancer during surgery for rectal cancer or pancreatic cancer with the fluorescent agent SGM-101.
  • Primary outcome : Safety and tolerability
  • Secondary outcome : Performance of SGM-101

Preliminary results for this trial were published in the Lancet Gastroenterology & Hepatology (Boogerd L.S.F. et al. 2018). It was shown that “in the expansion cohort, 19 (43%) of 43 lesions were detected using fluorescence imaging and were not clinically suspected before fluorescent detection, which changed the treatment strategy in six (35%) of 17 patients.”

Image guided surgery has entered a new era in which real applications in practice are within reach. Our combined effort of surgical oncologists with a world class drug development group as CHDR is unique in the world and opens enormously exciting visions that bring important medical interventions closer to the clinic
