CASI Pharmaceuticals Partner, BioInvent, To Present Further Positive Clinical Data On BI-1206 At ASH 2021
CASI Pharmaceuticals, Inc. announced that its partner BioInvent International has released positive interim data from the Phase 1/2a trial of BI-1206, an anti-FcγRIIB antibody combined with rituximab for treating non-Hodgkin's lymphoma. The study reported a 50% objective response rate among 12 patients, with long-lasting complete responses observed. The promising safety profile suggests potential for broader application across various cancers. CASI is responsible for the commercialization of BI-1206 in Greater China and anticipates further developments from BioInvent at the upcoming ASH 2021 meeting.
- 50% objective response rate and 58% disease control rate in the trial.
- Long-lasting complete responses sustained beyond 18-24 months.
- Good safety profile with manageable infusion-related reactions.
- Potential application of BI-1206 across multiple tumor types.
- None.
ROCKVILLE, Md., and BEIJING, Nov. 5, 2021 /PRNewswire/ -- CASI Pharmaceuticals, Inc. (Nasdaq: CASI), a U.S. biopharmaceutical company focused on developing and commercializing innovative therapeutics and pharmaceutical products, announces that its partner BioInvent International AB ("BioInvent") (OMXS: BINV), a biotech company focused on the discovery and development of novel and first-in-class immune-modulatory antibodies for cancer immunotherapy, announced additional positive interim top-line data from its novel anti-FcγRIIB antibody BI-1206. The data update comes from the company's Phase 1/2a clinical trial of BI-1206 in combination with rituximab (anti-CD20 monoclonal antibody) treating patients with indolent relapsed or refractory B-cell non-Hodgkin's lymphoma (NHL). The latest data will be published in a poster at the 63rd American Society of Hematology Annual Meeting and Exposition (ASH 2021) in December 2021.
BI-1206, in combination with rituximab, demonstrated an objective response rate (ORR) of
"The current data are very encouraging and already show the benefit of BI-1206 in advanced NHL. Without BI-1206, single agent rituximab does not work well for this group of patients. These results suggest that BI-1206 not only restores the anti-tumor response but can do it in a prolonged manner in many patients. All this has been achieved with a dosing regimen for BI-1206 that may yet be further improved, and we look forward to continuing its clinical development with the aim of improving treatment options for these patients," said Martin Welschof, PhD, CEO of BioInvent.
Wei-Wu He, Ph.D., CASI's Chairman, and Chief Executive Officer, said, "We are excited about the progression our partner BioInvent continues to make with BI-1206. We are optimistic about this anti-FcγRIIB antibody and its potential in restoring rituximab's activity in relapsed/refractory NHL patients. These clinical data provide more evidence of its safety and activity profile. We believe BI-1206 has potential application across multiple tumor types in both first line treatments and in relapsed/refractory settings, and are excited BioInvent's development and commercialization partner for making BI-1206 available to patients and healthcare providers across Greater China."
Pharmacodynamic studies highlighted in the ASH 2021 abstract suggest that increasing the dosing of BI-1206 could lead to complete receptor saturation over an extended time, potentially leading to additional clinical benefits.
BI-1206 is BioInvent's lead drug candidate and is currently being investigated in two Phase 1/2 trials. One is evaluating the BI-1206 combination with rituximab for the treatment of non-Hodgkin's lymphoma; and the other evaluates BI-1206 in combination with anti-PD1 therapy Keytruda® (pembrolizumab) in solid tumors.
Since October 2020, BioInvent has a licensing agreement with CASI Pharmaceuticals for China, including Hong Kong, Macau, and Taiwan. Under the terms of the agreement, BioInvent and CASI will develop BI-1206 in both hematological and solid cancers, with CASI responsible for commercialization in Greater China.
ASH 2021 will take place on December 11–14, 2021, at the Georgia World Congress Center - Atlanta, GA, and virtually. BioInvent will present a poster entitled "Phase 1/2a Clinical Trial of BI-1206, a Monoclonal Antibody to FcγRIIB (CD32B), in Combination with Rituximab in Subjects with Indolent B-Cell Non-Hodgkin Lymphoma That Has Relapsed or is Refractory to Rituximab". The abstract is available online from November 4, 2021, at 9.00 am EDT (2 pm CET) and will be presented on December 11 at 5.30 pm ET (11:30 pm CET).
In mid-December, BioInvent will hold a live-streamed KOL event where the ASH poster data will be discussed. In addition, the first data from the Phase 1/2a study of BI-1206 in combination with Keytruda for the treatment of solid tumors will be reviewed.
