BXCL701 is a first -in class, clinically validated, oral, small molecule that targets the next wave of immune checkpoints (Okondo et al. 2016) responsible for limiting the inflammatory, anti-tumor response of the innate immune system which represent the future of immuno-oncology.
Novel Small Molecule Sublingual Agent
BXCL501, is an α2-adrenergic receptor agonist that is known to induce a negative feedback loop for nor epinephrine release and in turn can decrease the sympathetic tone and attenuate neuroendocrine and hemodynamic responses.
|Hematological Malignancies (AML)||
BXCL702 has direct anti-tumor activity and can maintain the stimulation of the immune system by blocking immune cell exhaustion and energy. BXCL702 will be developed as a single agent treatment and in combination with immune checkpoints in hematological malignancies.
BXCL701 is a first-in-class, clinically validated, oral, small molecule that targets the next wave of immune checkpoints, as recently shown by Okondo et al (Nature Chemical Biology Nov 2016). It represents a novel, and highly attractive approach to the modulation of the tumor microenvironment needed to switch ‘‘cold’’ tumors into ‘‘hot’’ immune-permissive tumors. BXCL701 has demonstrated the modulation of relevant cytokine and immune cells, as well as single agent efficacy in immune-responsive tumors like melanoma in humans.
BXCL701 has shown synergistic anti-tumor activity in-vivo with anti-PD1, fully supported by mechanistic explanation at the molecular level: synergistic induction of anti-tumor cytokines, and at the cellular level: synergistic activation of T-cell and NK-cells and inhibition of immunosuppressive cells like MDSC and CAF.
BXCL701’s molecular targets are over-expressed and amplified in castration resistant prostate cancer with neuroendocrine phenotype, progressing after Zytiga and Xtandi, a much more aggressive tumor that presently has no treatment. BXCL701's molecular signature appears to overlap with amplification and overexpression of PDL1, which opens a unique competitive development approach in combination with immune checkpoint inhibitors.
BTI plans to develop BXCL701 in this segment of prostate cancer as a mono therapy and in combination with immune-checkpoint inhibitors.
There are many papers describing the role of FAP+ CAF in immune suppression in pancreatic cancer, and BXCL701 has already received orphan drug designation in pancreatic cancer. BTI is planning to collaborate with academic investigators to initiate a study in pancreatic cancer to exploit this unique mechanism.
Revolutionizing drug development and translation research in Immuno-Oncology (IO)
BioXcel’s Neuroscience programs are focused on discovering and developing therapeutics for neurological disorders with high unmet medical need. These include developing disease modifying agents as well as those agents that address symptoms such as agitation that represent significant unmet need in treating neuropsychiatric and neurodegenerative disorders.
BXCL501 is our most advanced Neuroscience program, which is being developed initially for the treatment of acute agitation in patients with schizophrenia and bipolar disorders. It is a selective adrenergic agent with a sublingual route of administration, which provides a fast onset of action doesn’t produce excessive sedation and is free from any associated side effects. It is well differentiated from routinely used antipsychotics which produce unwanted symptoms such as tremors, neutropenia and extra-pyramidal motor effects. Managing patient agitation in neuropsychiatric and neurodegenerative disorders represents a signiﬁcant challenge for physicians and caregivers, and BXCL501 has the potential to provide an efficient treatment regimen for these patients.
