New unpublished data from Dr. Katherine Fuh showed that biomarker high naïve ovarian cancer patients that had been shown to have a 47% response rate in the Phase 1b platinum-resistant ovarian cancer (PROC) study were poor responders to initial chemotherapy (i.e., treatment that did not contain batiraxcept).
|
|
●
|
Updated data as of April 30, 2022 from the ccRCC Phase 1b trial from 26 patients treated with batiraxcept in the Phase 1b portion of the trial at doses of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily in previously treated (2L+) patients with ccRCC:
|
|
o
|
There were no dose limiting toxicities observed at either dose;
|
|
o
|
14 of the 26 patients remain on study with 9 out of the 12 patients who ended treatment still in survival follow-up;
|
|
o
|
The best overall response rate (ORR, confirmed + unconfirmed) was 46% across both doses in the ITT population and 50% in patients dosed with 15 mg/kg (the recommended Phase 2 dose);
|
|
o
|
The best ORR 60% across both doses in the biomarker high population and 67% in the biomarker high population dosed at 15 mg/kg;
|
|
o
|
The 7-month progression-free survival (PFS) rate was 71% across both doses in the ITT population, 83% across both doses in the biomarker high population, and 91% in the 15 mg/kg biomarker high group; and
|
|
o
|
Eight patients (101-004, 101-005, 102-002, 104-003, 105-002, 105-004, 105-006, and 107-002) experienced resolution of one or more target lesions.
|
|
●
|
Updated data as of May 3, 2022 from the 21 patients dosed with 15mg/kg batiraxcept in combination with gemcitabine and nab-paclitaxel as a first-line treatment in patients with advanced or metastatic pancreatic adenocarcinoma in the Phase 1b pancreatic adenocarcinoma trial:
|
|
o
|
Analysis of all safety data to date demonstrates that batiraxcept has been generally well-tolerated with no unexpected safety signals;
|
|
o
|
The best ORR (confirmed + unconfirmed) was 29%;
|
|
o
|
As noted with the other programs, an observable correlation of baseline levels of serum soluble AXL (sAXL)/GAS6 to clinical activity was noted in this trial and the best ORR in that biomarker high population was 40%; and
|
|
o
|
Five patients (202-004, 202-005, 206-002, 213-002 and 214-001) experienced resolution of one or more target lesions with additional information on these patients:
|
|
■
|
206-002 and 213-002 have since progressed;
|
|
■
|
2 patients (213-002 and 214-001) had CA19-9 level that decreased to within normal limits during the study; and

An outline of a registrational ccRCC study recommended by FDA which involves an integrated P2/P3 study with interim analyses to look at futility in the biomarker low population and ORR for potential accelerated approval with PFS endpoint for full approval. This design provides an opportunity for accelerated approval and full approval in one study. The final PFS analysis will be conducted in the ITT and the biomarker high populations to increase the chance for success. The full protocol and statistical plan are in preparation for submission to FDA.

Updated milestones to reflect activities in 2H’23: Initiation of P2 PDAC trial, dependent on results of the P1b PDAC trial.
|
|
●
|
Updated milestones to reflect activities in 1H’24: Approval of PROC BLA, if trial is successful and if the Company successfully submit a BLA in 2H 2023; Initiate CTGF Clinical Studies, if IND accepted; and Safety and Preliminary Activity from P2 PDAC Trial, should the Company initiate a P2 PDAC trial.
