- Dose escalation portion of ongoing Phase 1b/2 pancreatic adenocarcinoma trial initiated, with preliminary results expected in 2H 2023
HOUSTON, Feb. 28, 2023 (GLOBE NEWSWIRE) -- Aravive, Inc. (Nasdaq: ARAV, “the Company”), a late clinical-stage oncology company developing targeted therapeutics to treat metastatic disease, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to batiraxcept for the treatment of pancreatic ductal adenocarcinoma cancer (PDAC).
The FDA’s Office of Orphan Products Development grants ODD status to a drug or biological product to prevent, diagnose or treat a rare disease or condition affecting fewer than 200,000 people in the USA. Companies that are granted ODD are eligible for incentives, including tax credits for qualified clinical trials, exemption from user fees and up to seven years of market exclusivity after approval.
“Receiving Orphan Drug Designation is another important milestone for batiraxcept, and it underscores the significant unmet medical need in patients with pancreatic cancer, typically diagnosed at an incurable advanced stage with a 5-year survival rate of 11%1,” said Gail McIntyre, Ph.D., DABT, Chief Executive Officer of Aravive. “Three patients from our P1b trial are still responding to treatment with 15mg/kg batiraxcept, gemcitabine and nab-paclitaxel after 1 year and one patient has a confirmed complete response. Consistent with our other clinical trials, we noted a relationship between clinical activity and batiraxcept drug levels, however highly fibrotic tumors like PDAC may require more batiraxcept than platinum-resistant ovarian cancer and clear cell renal cell cancer patients to reach the appropriate batiraxcept drug levels. Due to this characteristic of pancreatic cancer, we are testing higher doses of batiraxcept to see if we can increase the proportion of patients who benefit from the triplet regimen.”
Batiraxcept (15mg/kg on Days 1 & 15) is currently being evaluated in a Phase 1b/2 trial (NCT04983407) as first-line treatment in combination with gemcitabine (1000 mg/m2 on Days 1, 8, & 15) and nab-paclitaxel (125 mg/m2 on Days 1, 8, & 15) in patients with locally advanced (nonresectable Stage II or Stage III) or metastatic (Stage IV) pancreatic adenocarcinoma. The Phase 1b portion of the trial is ongoing and the dose escalation phase was initiated this month. Preliminary results from the 20mg/kg batiraxcept plus gemcitabine and nab-paclitaxel cohort are anticipated in the second half of 2023. In addition to ODD granted by the FDA in pancreatic cancer, batiraxcept was previously granted ODD by the European Commission in platinum resistant recurrent ovarian cancer (PROC) and was granted Fast Track Designation by the FDA in PROC and clear cell renal cell carcinoma (ccRCC).
Aravive, Inc. is a late clinical-stage oncology company developing targeted therapeutics to treat metastatic disease. Batiraxcept (formerly AVB-500), is an ultra-high affinity decoy protein that binds to GAS6, the sole ligand that activates AXL, thereby inhibiting metastasis and tumor growth, and restoring sensitivity to anti-cancer agents. Batiraxcept has been granted Fast Track Designation by the U.S. FDA for both clear cell renal cell carcinoma and platinum-resistant ovarian cancer and Orphan Drug Designation by the European Commission in platinum resistant recurrent ovarian cancer. Batiraxcept is in an active registrational Phase 3 trial in platinum resistant ovarian cancer (NCT04729608), a Phase 1b/2 trial in clear cell renal cell carcinoma (NCT04300140), and a Phase 1b/2 trial in pancreatic adenocarcinoma (NCT04983407). The Company is based in Houston, Texas and received a Product Development Award from the Cancer Prevention & Research Institute of Texas (CPRIT) in 2016. Additional information at www.aravive.com.
