Rilogrotug (AV-380) is an investigational drug and has not yet been approved by any health authorities.
Safety and efficacy have not yet been established.
Rilogrotug (also known by research code AV-380) is an investigational humanized IgG1 antibody that targets growth differentiation factor 15 (GDF-15). The amount of GDF-15 that circulates in the body increases in response to stress. At these higher levels, GDF-15 has been associated with cachexia in patients with cancer.
GDF-15 is a pro-inflammatory cytokine whose elevated circulating levels have been correlated with cachexia in certain types of cancers.
AVEO has initiated an open-label Phase 1b ascending dose study designed to evaluate the safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of rilogrotug (AV-380) in cancer patients with cachexia.
AVEO is currently enrolling patients in this study. For more information, go to clinicaltrials.gov.
Cachexia is a syndrome caused by multiple factors. Characteristics of cachexia include loss of appetite, and involuntary loss of weight, body fat, and skeletal muscle which leads to fatigue (tiredness), functional impairment (difficulty doing everyday tasks), increased treatment-related toxicity (side effects of treatment), poor quality of life, and reduced survival.1

Cachexia affects an estimated 50% to 80% of cancer patients and accounts for up to 30% of cancer deaths.2,3 Cachexia incidence varies by tumor type and ranges from >80% (gastric or pancreatic cancer), to ~50% (lung, prostate, or colon cancer), and ~40% (breast cancer and some types of leukemias).4
Cachexia causes severe unintentional weight loss and muscle wasting. People can feel extremely weak, fatigued, and have no appetite, making it difficult to stay healthy during cancer treatment.5 Cachexia can also take a significant emotional toll on patients and their families, affecting their psychological well-being and quality of life. 5

Cancer cachexia diagnosis includes involuntary weight loss of 5% or more in the preceding 6 months and loss of muscle mass.1 Currently there is no approved treatment, and approaches focus on dietary counseling, increased nutritional and caloric intake, and providing emotional support for patients and their families.1

AVEO is conducting a Phase 1b ascending dose study of AV-380 (Anti-GDF15 Monoclonal Antibody) in combination with standard-of-care therapy in cancer patients with cachexia.
As part of our goal to help patients with cancer live better lives, we are seeking to advance other candidates with the potential to positively impact treatment.
AVEO aims to leverage its existing collaborations and partnerships, as well as enter into new strategic collaborations and partnerships to continue to advance each of its product candidates.
