CHEMICAL (ACHIRAL)



Tepotinib is an investigational small molecule inhibitor of the c-Met receptor tyrosine kinase. Alterations of the c-Met signaling pathway are found in various cancer types and correlate with aggressive tumor behavior and poor clinical prognosis. Tepotinib is a potent and selective c-Met inhibitor, >200-fold selective for c-Met than IRAK4, TrkA, Axl, IRAK1, and Mer. Tepotinib is currently in Phase I/II trials in liver cancer and lung cancer.

CHEMICAL (ABSOLUTE)

Voclosporin (trans-ISA247) is a Cyclosporin A derivative and immunosuppressive compound currently being investigated for the treatment of psoriasis, lupus nephritis and for the prevention of organ rejection in kidney transplant patients. An animal study showed that a lower blood level of Voclosporin was able to produce a greater or similar inhibition of lymphocyte proliferation, expression of T-cell activation surface antigens, and T-cell cytokine production compared to Cyclosporin A. Voclosporin has been shown to be an efficacious and safe immunosuppressant in phase IIb and phase III trials in renal transplant recipients and in plaque psoriasis patients. In clinical trials, Voclosporin added to standard-of-care induction therapy for lupus nephritis increases complete renal remission (CRR) rates, but higher rates of adverse events including death were observed.

CHEMICAL (ABSOLUTE)

MK-3118 is an orally active inhibitor of fungal β-(1,3)-glucan synthase patented by Merck Sharp & Dohme Corp for the treatment of fungal infections. MK-3118 demonstrated enhanced efficacy for most C. albicans and C. glabrata ER isolates relative to caspofungin. MK-3118 showed no or poor activity against Mucoromycotina and Fusarium spp. However, MK-3118 was highly active against Paecilomyces variotii and was the only compound displaying some activity against notoriously pan-resistant Scedosporium prolificans.

CHEMICAL (ABSOLUTE)


FINERENONE is a potent and selective nonsteroidal mineralocorticoid receptor antagonist. Results in preclinical studies showed that lower doses of FINERENONE were needed to achieve similar cardiorenal protective effects compared to both spironolactone and eplerenone. It is in phase III clinical trials for the treatment of diabetic kidney disease.

Difelikefalin is an orally bioavailable second-generation peptide. It is an investigational peripheral kappa opioid receptor agonist. Difelikefalin significantly reduced moderate to severe chronic itching while achieving across-the-board clinically meaningful improvements in quality of life measures in patients with hemodialysis-associated pruritus in a phase 2 study. In a phase 2 clinical investigation, difelikefalin was safe, well tolerated and showed robust analgesic activity for postoperative pain in female patients undergoing laparoscopy, with a significant reduction in post-operative morphine consumption and opioid-related side effects. Now difelikefalin is in phase III clinical trials for the treatment of post-operative pain and pruritus.
KD025 is an orally available, selective small molecule inhibitor of ROCK2 (Rho-associated coiled-coil kinase 2), a molecular target in multiple autoimmune, fibrotic and neurodegenerative diseases. KD025 is the only ROCK2-specific inhibitor in the clinical trials. KD025 down-regulates the IL-17 and IL-21 secretion in human PBMCs, and leads to down-regulation of STAT3 phosphorylation, IRF4, and RORγt expression in CD4+ T cells. Kadmon Pharmaceuticals initiated phase II clinical trials of KD025 for the treatment of Graft-versus-host disease; Idiopathic pulmonary fibrosis; Plaque psoriasis.
Umbralisib (TGR-1202) is an orally available PI3K delta inhibitor, targeting the delta isoform with nanomolar potency and several fold selectivity over the alpha, beta, and gamma isoforms of PI3K. The delta isoform of PI3K is strongly expressed in cells of hematopoietic origin and is believed to be important in the proliferation and survival of B-cell lymphocytes. Inhibition of PI3K delta signaling with umbralisib has demonstrated robust activity in numerous pre-clinical models and primary cells from patients with hematologic malignancies. Umbralisib is currently in Phase 3 clinical development in combination with Ublituximab for patients with hematologic malignancies.
Maribavir (previously known as 1263W94) is a novel benzimidazole riboside compound. This drug was in phase III of clinical trial for the prevention of cytomegalovirus (CMV) infections in transplant patients, sponsored by ViroPharma. However, drug failed to demonstrate a higher efficacy rate than the placebo. Maribavir has activity against cytomegalovirus and Epstein-Barr virus (EBV), but not against other human herpesviruses. Maribavir’s mechanism of action is unique and is complex compared to the currently approved antivirals for CMV. Maribavir inhibits the viral UL97 kinase rather than the viral DNA polymerase. The UL97 kinase is important for viral DNA elongation, DNA packaging, and nuclear egress of encapsidated viral DNA. In addition, maribavir inhibits the EBV DNA polymerase processivity factor (BMRF1), reduces the level of certain EBV glycoproteins, and inhibits viral transcription. However, future work will be designed to address the interaction of MBV and BGLF4 and to evaluate the mechanisms through which maribavir downregulates viral transcripts. BGLF4 belongs to the family of conserved herpesvirus PKs, which includes HCMV UL97, HSV UL13, and HSV US3. Maribavir does need to be phosphorylated for its activity.
