GBM AGILE trial knowledge reveals clinically significant enchancment in a prespecified secondary evaluation for general survival in paxalisib-treated, newly identified unmethylated sufferers with glioblastoma
SYDNEY, July 10, 2024 /PRNewswire/ — Kazia Therapeutics Restricted (NASDAQ: KZIA), an oncology-focused drug growth firm, is happy to announce outcomes from GBM-AGILE, a part II/III examine that included an analysis of paxalisib versus commonplace of care (SOC) for sufferers with glioblastoma (NCT03522298), a life-threatening mind most cancers, the place there’s an pressing unmet want for brand new therapeutics.
GBM AGILE STUDY
GBM AGILE is an adaptive part II/III international trial sponsored by the International Coalition for Adaptive Analysis (GCAR), a nonprofit group comprised of among the world’s foremost scientific, translational, and primary science researchers, from establishments resembling Memorial Sloan Kettering Most cancers Heart and Dana-Farber Most cancers Institute. The trial is designed to effectively display screen for and characterize the response of glioblastoma (GBM) sufferers to novel investigative brokers. Using a fancy modern design, Bayesian rules are utilized to the first endpoint (Total Survival) comparability of the investigational brokers to sufferers receiving Customary of Care (SOC) enrolled from the examine begin (additionally known as cumulative management inhabitants). Normally, secondary analyses and endpoints are assessed based mostly on established statistical fashions compared to the management sufferers enrolled concurrently the investigational agent (concurrent management inhabitants).
Paxalisib is the third drug candidate to finish its analysis within the examine and was evaluated in newly identified glioblastoma sufferers with unmethylated MGMT promoter standing in addition to in sufferers with recurrent illness.
GBM AGILE Paxalisib Outcomes
Kazia CEO, Dr John Good friend acknowledged, “We’re excited to have proven a 3.8 month enchancment in general survival, an approximate 33% enchancment, for newly identified unmethylated sufferers with GBM in comparison with the concurrent commonplace of care arm. Having comparable Total Survival knowledge throughout two impartial research is a compelling consequence on this troublesome to deal with glioblastoma inhabitants. We stay up for discussing potential approaches for an accelerated approval pathway for paxalisib with the FDA.”
A complete of 313 newly identified unmethylated (NDU) sufferers and recurrent sufferers being handled at high US most cancers hospitals have been randomized in Stage 1 to both a paxalisib remedy arm (60 mg/day) or the SOC concurrent management arm from January 2021 to Might 2022. The cumulative management arm was enrolled from July 2019 (GBM Agile examine begin date) to Might 2022.
For the first evaluation the median Total Survival (OS) was 14.77 months for paxalisib-treated NDU sufferers (n=54) versus 13.84 months for cumulative SOC NDU sufferers (n=75).
For a prespecified secondary evaluation within the NDU sufferers, median OS was 15.54 months within the paxalisib arm (n=54) versus 11.89 months for concurrent SOC (n=46). As well as, a prespecified sensitivity evaluation in NDU sufferers confirmed comparable median OS distinction between paxalisib handled sufferers (15.54 months) and concurrent SOC sufferers (11.70 months).
The secondary evaluation outcomes are in line with the beforehand reported Firm-sponsored part II examine, the place median OS was 15.7 months (n=27) for paxalisib handled NDU sufferers in comparison with 12.7 months traditionally reported with temozolomide on this affected person group (Wen 2022).
Paxalisib was effectively tolerated in GBM-AGILE, and no new security indicators have been recognized on this affected person inhabitants.
An efficacy sign was not detected within the recurrent illness inhabitants (median OS of 9.69 months for concurrent SOC (n=113) versus 8.05 months for paxalisib (n=100). Related outcomes on this inhabitants have been reported within the different two drug candidates which have accomplished the GBM AGILE trial. Kazia is at present pursuing additional analyses of this knowledge to elucidate potential indicators for additional consideration.
Primarily based on the totality of knowledge out there from all accomplished paxalisib scientific research in newly identified unmethylated GBM sufferers, Kazia will request a gathering with the US Meals & Drug Administration (FDA) to debate the outcomes and decide if a possible path to accelerated approval is suitable for paxalisib.
Paxalisib has beforehand obtained orphan drug designation and quick observe designation from the FDA for glioblastoma in unmethylated MGMT promoter standing sufferers, following radiation plus temozolomide remedy.
Full knowledge together with secondary endpoints from the paxalisib arm of the GBM AGILE examine is predicted to be offered at a scientific assembly later this 12 months.
About Kazia Therapeutics Restricted
Kazia Therapeutics Restricted (NASDAQ: KZIA) is an oncology-focused drug growth firm, based mostly in Sydney, Australia.
Our lead program is paxalisib, an investigational brain-penetrant inhibitor of the PI3K / Akt / mTOR pathway, which is being developed to deal with a number of types of mind most cancers. Licensed from Genentech in late 2016, paxalisib is or has been the topic of ten scientific trials on this illness. A accomplished Section 2 examine in glioblastoma reported early indicators of scientific exercise in 2021, and a pivotal examine in glioblastoma, GBM AGILE, has been accomplished with presentation of paxalisib arm knowledge anticipated later in 2024 at a serious medical convention. Different scientific trials involving paxalisib are ongoing in mind metastases, diffuse midline gliomas, and first CNS lymphoma, with a number of of those trials having reported encouraging interim knowledge.
Paxalisib was granted Orphan Drug Designation for glioblastoma by the FDA in February 2018, and Quick Observe Designation (FTD) for glioblastoma by the FDA in August 2020. Paxalisib was additionally granted FTD in July 2023 for the remedy of strong tumour mind metastases harboring PI3K pathway mutations together with radiation remedy. As well as, paxalisib was granted Uncommon Pediatric Illness Designation and Orphan Drug Designation by the FDA for diffuse intrinsic pontine glioma in August 2020, and for atypical teratoid / rhabdoid tumours in June 2022 and July 2022, respectively.
