oregovomab

Mechanism：

A monoclonal antibody that activates CA123-specific T cell immune response

Designation：

Fast Track Designation by the U.S. FDA; Orphan Drug Designations by the U.S. FDA and EMA of the EU

Indication：

The first-line treatment of patients with advanced primary ovarian cancer

Clinical Progress：

As of June 30, 2022, clinical study was initiated at 130 trial sites around the world, having enrolled a total of 330 patients. OncoQuest is currently preparing for adding the non-clinical tests required by the CDE and will soon submit an IND to the CDE in order to expand the multi-regional clinical trial (MRCT) to China.

apabetalone（RVX-208）

Mechanism：

BET bromodomain protein inhibitor

Designation：

Breakthrough Therapy designation by the US FDA

Indication：

In combination with standard of care therapies including high-intensity statins, for the secondary prevention of major adverse cardiac events (MACE) in patients with type 2 diabetes who have recently experienced acute coronary syndromes.

Clinical Progress：

The BETonMACE 2 trial will soon be initiated and the breakthrough Phase III BETonMACE trial was already completed in September 2019. Although the Phase III BETonMACE trial did not reach its primary endpoint, the FDA has encouraged the continued exploration of the subgroups in the BETonMACE2 trial. Hepalink is poised to accelerate the development of this drug candidate, including those planned clinical trials as well as the implementation of its overall drug development strategy.

tosatoxumab（AR-301）

Mechanism：

A fully human IgG1 monoclonal antibody targeting S aureus α-toxin

Designation：

A Fast Track Designation from the U.S. FDA, and Orphan Drug Designations from both the U.S. FDA and EMA of the EU

Indication：

The treatment of ventilator associated pneumonia (VAP) caused by S. aureus

Clinical Progress：

As of June 30, 2022, the study has enrolled a total of 166 patients globally. Among them, 104 patients met the criteria for modified intention-to-treat (mITT).

H1710

Mechanism：

Heparanase (HPA) inhibitor preparation

Indication：

The non-clinical pharmacodynamic studies of H1710 have already observed promising antitumor activity in multiple tumor models in comparison with standard of care therapies.

Clinical Progress：

As of June 30, 2022, Hepalink has completed the production of H1710 API and preparation. The stability studies of the API and preparation are still on-going, and the stability study of the H1710 preparation is expected to last three months. The compatible stability study and impurity analysis of the H1710 preparation have already been completed.
