Alloplex opens third prestigious site for SUPLEXA-101 first-in-class cellular therapy trial in oncology patients

Southern Oncology Clinical Research Unit in Adelaide joins Cancer Research SA, also in Adelaide, and Gallipoli Medical Research Foundation of Brisbane for the Phase 1 trial of Alloplex Biotherapeutics' autologous SUPLEXA cell immunotherapy.

Boston, USA; Adelaide and Brisbane, Australia — December 15, 2022. 

Alloplex Biotherapeutics today announced the opening of the third site in its first-in-human clinical trial of SUPLEXA: Southern Oncology Cancer Research Unit ‘SOCRU’.

SUPLEXA therapy is a highly-differentiated, autologous, non-engineered, multi-cellular therapy derived from patient peripheral blood mononuclear cells.

This Phase 1 is a first-in-human, open-label single agent basket study. The primary outcome measure of the trial is to assess the safety, tolerability, and preliminary clinical efficacy of repeated intravenous (IV) infusions of SUPLEXA cells in patients with a variety of measurable metastatic solid tumours and haematologic malignancies. For this initial trial, subjects must meet defined entry criteria and have measurable relapsed or refractory advanced malignancy for which no standard therapy exists

The study (NCT05237206) is now being conducted in two sites in South Australia and one site in Queensland:

  • Cancer Research SA (CRSA) with Assoc. Professor Rohit Joshi as the Principal Investigator at St Andrew’s Medical Centre, Adelaide, South Australia
  • Southern Oncology Clinical Research Unit (SOCRU) in Adelaide, South Australia, with Dr. Ganessan Kichenadasse as Investigator; and at
  • Gallipoli Medical Research Foundation (GMRF), Greenslopes Hospital in Brisbane, Queensland with Dr. Jeffrey Goh as Investigator

Since the in-human trial commenced in April 2022, clinical experience shows that SUPLEXA cells are well tolerated in patients across a wide array of cancer types.

“We are delighted to welcome these prestigious sites to the SUPLEXA-101 first-in-class cellular therapy trial in oncology patients. The cutting-edge individualised therapy has shown a remarkable safety and tolerability profile, enabling us to support treatment of many cancer types,” said Alloplex’s Scientific Founder and CEO, Dr. Frank Borriello. ”We are encouraged by the early signals and look forward to further data from these clinical trial sites” he said.

Alloplex Biotherapeutics, Inc. is a private-company with headquarters in Boston, USA and a wholly-owned subsidiary, Alloplex Australia Pty. Ltd based in Melbourne, Australia. Alloplex is a clinical stage company focused on developing SUPLEXA; a potential first-in-class autologous, pan-cancer therapy for the treatment of cancer patients. The privately-held company was established in 2016 by Scientific Founder and CEO, Dr. Frank Borriello, MD, PhD on an original concept he developed.

About SUPLEXA and The Phase 1 trial:

SUPLEXA Therapeutic Cells are a novel a highly-differentiated PBMC-derived, autologous cellular therapy intended to treat cancer via a multi-modal anti-tumor mechanism of action. Following a short two- week ex vivo activation procedure, the PBMCs are differentiated in SUPLEXA cells – which contain NK, NK-T, CD8 and CD4 positive cells as well as gamma delta T cells. They are administered as three weekly IV infusions.

For the Phase 1 ‘SUPLEXA-101’ trial, enrolling under reference number NCT05237206, subjects must meet defined entry criteria and have measurable relapsed or refractory advanced malignancy for which no standard therapy exists. The primary outcome measure of the trial is to assess safety and tolerability of SUPLEXA in subjects with malignant solid tumours and haematologic malignancies. An Independent Data Monitoring Committee (IDMC) will monitor safety on a regular basis throughout the study.

In January 2022, Australia’s Human Research Ethics Committee ‘HREC’ approved Alloplex’s submission to proceed to in-human trials. In April 2022, Alloplex Biotherapeutics announced the site opening for its first-in-human (FIH) clinical trial of SUPLEXA therapeutic cells at CRSA with Dr. Rohit Joshi as Principal Investigator.
