AZD5335 / AstraZeneca - LARVOL DELTA

Initial results from a first-in-human study of AZD5335, a folate receptor α (FRα)-targeted antibody-drug conjugate, in patients (pts) with platinum-resistant recurrent ovarian cancer (PRROC) (ESMO 2024) - P1/2 | "AZD5335 demonstrated a manageable safety profile and preliminary signs of efficacy. Dose optimisation is underway in module M1B. Ronnie Shapiro-Frommer and Kazuki Sudo have contributed equally to the study."

AstraZeneca steps out from Daiichi's shadow, posting data on in-house rivals to AbbVie... (FierceBiotech) - P1/2a | N=150 | NCT05797168 | Sponsor: AstraZeneca | "The poster features data on 39 ovarian cancer patients who received one of five doses of AZD5335. In the 38 dosed patients with an available on-treatment scan at data cutoff, AstraZeneca reported a 34.2% response rate. The response rate was 46.2% in participants with high FRα and 35.7% in patients with low FRα. Excluding the lowest dose boosted the response rates to 55.6% and 41.7%, respectively...The cohorts are small—there were nine people in the analysis that yielded the 41.7% response rate—but there are early signs AZD5335 may be competitive."

FONTANA: A phase I/IIa study of AZD5335 as monotherapy and in combination with anti-cancer agents in patients with solid tumours (ESMO 2023) - P1/2 | "The study will evaluate AZD5335 as monotherapy in patients with ovarian cancer or lung adenocarcinoma (Module 1), or AZD5335 in combination with AZD5305, a selective poly(ADP-ribose) polymerase 1 inhibitor, in patients with ovarian cancer (Module 2). Secondary objectives include assessment of objective response rate, duration of response, disease control rate, and progression-free survival by RECIST v1.1, and overall survival; characterising the pharmacokinetics of AZD5335 when given as monotherapy or in combination; and assessing immunogenicity. The study will be open to recruitment by 25 May 2023."

First disclosure of AZD5335, a TOP1i-ADC targeting low and high FRα-expressing ovarian cancer with superior preclinical activity vs FRα-MTI ADC (AACR 2023) - "Furthermore, AZD5335 demonstrated superior activity vs an FRα-MTI benchmark ADC with respect to anti-tumor activity and duration of response in two PDX models with low-to-medium FRα expression at equal or higher drug doses (e.g., in OV0857-CIS: 96% TGI vs 24% TGI at 5 mg/kg and 95% TGI vs 2% TGI at 2.5 mg/kg of a single IV dose AZD5335 and FRα-MTI, respectively). These data indicate that AZD5335 is a promising therapeutic candidate for the treatment of ovarian cancers across the spectrum of FRα-expression."
