NAPISTAR 1-01: An International Phase I/II Trial of the Novel ADC TUB-040 in Advanced/Metastatic NSCLC Adenocarcinoma
(IASLC-WCLC 2025)
- P1/2 | "The dose-escalation framework includes initial double-dosing steps with a 100% increment over the standard dose, transitioning to modified Fibonacci increments (67%, 50%, and 33% dose increments) with intra-patient escalation permissible at low exposure levels. Phase IIa involves the randomization of patients for dose optimization at two or more doses to further characterize the safety profile and identify the optimal therapeutic dose."

TUB-040, a homogenous and hydrophilic NaPi2b-targeting ADC with stably linked exatecan, exhibits long-lasting anti-tumor activity and a well-tolerated safety profile.
(PubMed, Mol Cancer Ther)
- "Repeated-dose toxicological assessment in rats indicates that TUB-040 is well-tolerated, with no evidence of lung toxicity or thrombocytopenia. Taken together, TUB-040 is designed to enable long-lasting, durable tumor responses and to optimize both efficacy and tolerability, supporting the advancement of TUB-040 into clinical trials."

(Businesswire)
- "Tubulis today presented comprehensive preclinical data on its two lead antibody-drug conjugate (ADC) candidates TUB-030 and TUB-040 at this year’s Annual Meeting of the American Association for Cancer Research....TUB-040:...The ADC candidate is highly stable and highly inert in circulation, enabling powerful and continued on-tumor delivery of the payload, leading to complete eradication of tumors with a low dose single treatment in multiple ovarian cancer mouse models....In ovarian cancer and non-small-cell lung cancer (NSCLC) patient derived xenograft mouse models, treatment with TUB-040 led to robust long-lasting tumor regressions. Repeat-dose toxicology studies of TUB-040 in non-human primates demonstrated that TUB-040 was well tolerated with minor and reversible adverse effects."
