suzhou, december 20, 2019 – jiangsu alphamab biopharmaceuticals co., ltd. (“jiangsu alphamab”, or “the company”), a wholly owned subsidiary of alphamab oncology (stock code:, announced today that it has signed a collaborative partnership agreement with 3d medicines and tracon pharmaceuticals (“tracon”) for the clinical development and commercialization of kn035, a pd-l1 single-domain antibody, for soft tissue sarcoma in north america.

kn035 is a pd-l1 single-domain antibody independently discovered by jiangsu alphamab. it is expected to become the world’s first pd-l1 immuno-oncology drug that can be administered by subcutaneous injection. the company and 3d medicines have co-developed the product to late clinical stage. in this three-party cooperation, tracon will be responsible for the clinical development and commercialization of kn035 for the treatment of soft tissue sarcomas in north america and pay sales-based royalties to the company and 3d medicines. the company will supply kn035 at pre-negotiated prices.

dr. ting xu, founder, chairman and ceo of alphamab oncology, said, “the collaboration is an important part of kn035 global development strategy. as the most advanced single domain antibody in immuno-oncology with advantage of subcutaneous adminstration, we are confident it will become a valuable option for cancer patients.”

john gong, ceo of 3d medicines, commented, “in earlier clinical trials, the safety and efficacy profiles of kn035 are comparable to other pd-1/pd-l1 antibodies in the market. currently the registration trial in msi-h patients is ongoing, and we believe that kn035 will give cancer patients a better option with subcutaneous injection in the united states.”

charles theuer, m.d., ph.d., president and ceo of tracon, added, “given the activity of other pd-1 and pd-l1 inhibitors in sarcoma, we believe a registration enabling study of kn035 in the sarcoma subtype of ups will be meaningful to patients and providers, and is strategically aligned with tracon’s mission to rapidly develop and commercialize drugs targeting unmet medical need indications in the u.s. we expect to discuss our plan of initiating a pivotal trial of kn035 in ups with the u.s. fda in early 2020. our ultimate goal is to enable a biomarker directed approach for treatment with kn035 in patients with multiple types of soft tissue sarcoma.”
