G-protein Ras (rat sarcoma virus) inhibitor, antineoplastic, LUNA 18, CHUGAI, AW3YP3CD9X
Paluratide (development code LUNA18) was an investigational cyclic peptide KRAS inhibitor developed by Chugai Pharmaceutical, a member of the Roche Group, for the treatment of cancers with KRAS mutations.[1] The compound was notable as an orally bioavailable macrocyclic peptide that could target intracellular protein-protein interactions, a class of targets traditionally considered “undruggable.”[2]
Development was discontinued in July 2025 due to a narrow therapeutic window compared to competing KRAS inhibitors.[3]
Ras Inhibitor LUNA18 is an orally bioavailable cyclic peptide and Ras inhibitor, with potential antineoplastic activity. Upon oral administration, Ras inhibitor LUNA18 selectively targets, binds to and inhibits Ras, thereby inhibiting Ras-dependent signaling and inhibits proliferation of tumor cells in which Ras is overexpressed and/or mutated. Ras serves an important role in cell signaling, division and differentiation. Mutations of Ras may induce constitutive signal transduction leading to tumor cell growth, proliferation, invasion, and metastasis.
Paluratide (LUNA18 is synthesized using a novel liquid-phase peptide synthesis (LPPS) method, not traditional solid-phase methods, to overcome challenges with N-alkylated cyclic peptides. This process involves a convergent route of 24 telescoped chemical transformations, a final crystallization step, and a focus on specific strategies to manage side reactions like diketopiperazine formation and low reactivity of sterically hindered amino acids.
Key aspects of the synthesis
- Liquid-phase synthesis: A novel, high-yielding LPPS process was developed to enable the large-scale production of paluratide. This is a departure from traditional solid-phase methods, which have limitations with solubility and waste.
- Convergent synthetic route: The synthesis uses a convergent approach, meaning smaller fragments of the peptide are synthesized separately and then joined together. The overall process includes 24 telescoped chemical transformations followed by a final crystallization step.
- Addressing synthesis challenges: Specific strategies were employed to overcome key difficulties:
- Low reactivity: Amino acids with N-alkylation are sterically hindered, so more reactive and stable protecting groups were used to ensure efficient coupling.
- Side reactions: The method was designed to prevent side reactions like diketopiperazine formation in intermediates and incomplete hydrolysis of active esters.
- Instability: The peptide backbone is sensitive to acidic conditions, so a mildly acidic aqueous medium was chosen for workup and purification to maintain stability.
- Protecting group selection: Cbz-protected amino acid active esters were preferred over Boc-protected ones because they are less prone to forming N-carboxyanhydrides (NCA) under activating conditions, which can reduce yield and purity.
- Purification: A final crystallization step is used for purification.

Mechanism of action
Paluratide functions as a pan-RAS inhibitor, targeting multiple RAS isoforms including KRAS, NRAS, and HRAS.[1] The compound binds with high affinity to KRASG12D, with a dissociation constant (Kd) of 0.043 nM, and blocks the interaction between KRASG12D and the guanine nucleotide exchange factor SOS1 with an IC50 of less than 2.2 nM.[4]
Unlike covalent KRAS inhibitors that target specific mutations (such as sotorasib for KRASG12C), paluratide was designed to inhibit RAS proteins through disruption of protein-protein interactions with guanine nucleotide exchange factors (GEFs).[1] This mechanism allows the drug to affect RAS signalling regardless of the specific mutation, theoretically providing broader applicability across different KRAS-mutant cancers. The compound also demonstrates activity against downstream signalling pathways, affecting ERK and AKT phosphorylation.[4]
Medical uses
Paluratide was being developed for the treatment of locally advanced or metastatic solid tumors harbouring RAS gene alterations.[5] The drug demonstrated significant cellular activity against multiple cancer types with KRAS mutations in preclinical studies, including colorectal cancer, gastric cancer, non-small cell lung cancer, and pancreatic cancer.[1]
Chemistry
Paluratide is an 11-member (11-mer) cyclic peptide with a molecular weight in the range of 1000–2000 g/mol, classified as a “middle-size” cyclic peptide.[1] The compound features extensive N-alkylation, a modification that reduces hydrogen bond donors and improves oral absorption while maintaining cellular permeability.[2] Its structure allows it to navigate the challenging boundary between small molecules and biologics, achieving properties of both classes. The compound demonstrated oral bioavailability ranging from 21% to 47% in preclinical animal studies without requiring special formulations.[1]
Discovery
Paluratide was discovered through Chugai Pharmaceutical’s cyclic peptide platform using an mRNA display library screening approach.[1] The initial hit compound, designated AP8747, was identified from the mRNA display library and subsequently underwent extensive chemical optimization without scaffold hopping (maintaining the basic cyclic peptide structure).[1] The optimization focused on increasing plasma stability, improving absorption, reducing clearance, and reducing hydrogen bond donors to achieve oral bioavailability.
The final clinical compound, LUNA18, emerged after modifications to four amino acid positions (positions 5, 7, 10, and 11) from an intermediate compound (compound 40). Key structure-activity relationship findings included: the side chain at position 5 preferring aromatic over aliphatic groups; physicochemical properties being adjustable at position 11; and biological activity enhancement through modifications at positions 7 and 10.[1]
Chugai also developed a novel synthetic methodology that enabled the broadly applicable synthesis of highly N-alkylated cyclic peptide-like drugs.[6] This method overcame three major technical challenges: formation of diketopiperazine, insufficient reactivity of amidation due to steric hindrance, and instability of cyclic peptides under acidic conditions. Using this approach, more than 4,000 cyclic peptides were synthesized with a process yield of 31% and final product purity of 97%.[6]
Clinical trials
A Phase 1 dose-escalation and cohort expansion study (NCT05012618) was initiated in August 2021 to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary activity of paluratide administered as a single agent or in combination with other anti-cancer drugs.[5] The study, in the United States and Japan, was designed to enrol approximately 195 patients with locally advanced or metastatic solid tumors positive for documented RAS alterations.[5]
Paluratide was administered orally as capsules.[5] The study also evaluated combination therapy with cetuximab, an EGFR inhibitor.[5]

Nuvisertib is an orally available, second-generation and selective ATP-competitive inhibitor of proviral integration site for Moloney murine leukemia virus (PIM) kinases, with potential antineoplastic activity. Upon oral administration, nuvisertib selectively binds to and prevents the activation of the PIM kinases. This prevents the activation of PIM-mediated signaling pathways and inhibits proliferation in cells that overexpress PIM. PIMs, constitutively active proto-oncogenic serine/threonine kinases, are upregulated in various types of cancers and play key roles in tumor cell proliferation and survival.
Nuvisertib, also known as TP-3654, is an oral, investigational, and highly selective PIM1 kinase inhibitor being studied in a Phase 1/2 clinical trial for intermediate- or high-risk myelofibrosis (MF). It is not currently an approved medication.
Key Information
- Mechanism of Action: Nuvisertib targets the PIM1 kinase pathway, which is often overactive in myelofibrosis and can promote cancer cell growth. By inhibiting this pathway, nuvisertib is being investigated for its potential to manage symptoms, reduce spleen size, improve blood counts, and slow the progression of bone marrow fibrosis.
- Current Status: Nuvisertib is in ongoing Phase 1/2 clinical trials (NCT04176198) as a monotherapy and in combination with JAK inhibitors like ruxolitinib and momelotinib.
- Designations: Nuvisertib has received Orphan Drug Designation for myelofibrosis

REF
– Nuvisertib (TP-3654), an investigational highly selective oral PIM1 kinase inhibitor, is being evaluated in patients with relapsed or refractory myelofibrosis (MF) –
– Nuvisertib demonstrated symptom and spleen responses correlating with cytokine modulation in the preliminary Phase 1/2 data recently presented at the European Hematology Association (EHA) 2025 Congress –
MARLBOROUGH, Mass., June 12, 2025 /PRNewswire/ — Sumitomo Pharma America, Inc. (SMPA) today announced that the U.S. Food and Drug Administration (FDA) granted Fast Track Designation to nuvisertib (TP-3654) for the treatment of patients with intermediate or high-risk myelofibrosis (MF). The FDA Fast Track Designation is granted to investigational therapies being developed to treat serious or life-threatening conditions that demonstrate the potential to address unmet medical needs. Nuvisertib is an oral, investigational, highly selective inhibitor of PIM1 kinase, which demonstrated clinical activity including symptom and spleen responses correlating with cytokine modulation in the updated preliminary Phase 1/2 data presented at the European Hematology Association (EHA) 2025 Congress in Milan, Italy.
MF, a serious and rare type of blood cancer, is characterized by the buildup of fibrous tissues in the bone marrow which is caused by dysregulation in the Janus-associated kinase (JAK) signaling pathway. The clinical manifestations of MF include an enlarged spleen, debilitating symptoms and reduction in hemoglobin and/or platelets. MF affects 1 in 500,000 people worldwide.1
“This positive momentum for nuvisertib signals strong promise in our pipeline and reflects our dedication to addressing unmet medical needs on behalf of patients with myelofibrosis and their families,” said Tsutomu Nakagawa, Ph.D, President and Chief Executive Officer of SMPA. “Receiving FDA Fast Track Designation for nuvisertib in the treatment of myelofibrosis reinforces our confidence in its potential as a treatment option for patients facing a poor prognosis with limited treatment options. We are committed to working closely with the FDA to progress the clinical development of nuvisertib and bring an alternative treatment option to patients with myelofibrosis.”
Updated data from the ongoing Phase 1/2 study of nuvisertib in patients with relapsed/refractory MF were presented at the EHA Congress on June 12, 2025. Preliminary data showed that nuvisertib monotherapy appears to be well tolerated with no dose-limiting toxicities (DLTs). Evaluable patients showed clinical activity including a ≥25% spleen volume reduction (SVR25) in 22.2% of patients and a ≥50% reduction in total symptom score (TSS50) of 44.4% of patients, as well as improvement of bone marrow fibrosis (42.9% patients), hemoglobin (24% patients) and platelet count (26.7% patients). Data also showed that nuvisertib treatment led to significant cytokine modulation [reduction of pro-inflammatory cytokines (e.g. EN-RAGE, MIP-1β) and increase of anti-inflammatory cytokines (e.g. adiponectin)], which demonstrated significant (p<0.001) correlation with symptom and spleen responses. Preclinical2 and emerging clinical data support the development of nuvisertib in combination with JAK inhibitors for the treatment of patients with MF.
“The data observed to date demonstrate promising clinical activity for nuvisertib and the strong potential for selective PIM1 inhibition to slow the progression of myelofibrosis,” said Jatin Shah, MD, Chief Medical Officer, Oncology. “Patients with myelofibrosis are in need of new therapeutic approaches, including combination treatment options, that can provide increased and durable response rates with limited hematologic adverse events. The FDA Fast Track Designation reinforces the potential of nuvisertib to provide clinical benefits for patients with myelofibrosis, an unmet medical need.”
About Nuvisertib (TP-3654)
Nuvisertib (TP-3654) is an oral investigational selective inhibitor of PIM1 kinase, which has shown potential antitumor and antifibrotic activity through multiple pathways, including induction of apoptosis in preclinical models.2,3 Nuvisertib was observed to inhibit proliferation and increase apoptosis in murine and human hematopoietic cells expressing the clinically relevant JAK2 V617F mutation.3 Nuvisertib alone and in combination with ruxolitinib showed white blood cell and neutrophil count normalization, and also reduced spleen size and bone marrow fibrosis in JAK2 V617F and MPLW515L murine models of myelofibrosis.2 The safety and efficacy of nuvisertib is currently being clinically evaluated in a Phase 1/2 study in patients with intermediate and high-risk myelofibrosis (NCT04176198). The U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation to nuvisertib for the indication of myelofibrosis in May 2022. The Japan Ministry of Health, Labour and Welfare (MHLW) granted Orphan Drug Designation to nuvisertib for the treatment of myelofibrosis in November 2024.

Neladalkib is a small molecule drug. The usage of the INN stem ‘-alkib’ in the name indicates that Neladalkib is a ALK (anaplastic lymphoma kinase) inhibitor. Neladalkib is under investigation in clinical trial NCT06765109 (Neladalkib (NVL-655) for TKI-naive Patients With Advanced ALK-Positive NSCLC). Neladalkib has a monoisotopic molecular weight of 452.15 Da.
ALK Inhibitor NVL-655 is an orally bioavailable, brain-penetrant, selective small molecule inhibitor of the receptor tyrosine kinase (RTK) anaplastic lymphoma kinase (ALK), with potential antineoplastic activity. Upon oral administration, ALK inhibitor NVL-655 specifically targets, binds to and inhibits ALK fusion proteins and activating mutations, including the acquired resistance mutations solvent front mutation (SFM) G1202R and the compound mutations G1202R/L1196M and G1202R/G1269A. The inhibition of ALK leads to the disruption of ALK-mediated signaling and the inhibition of cell growth in ALK-expressing tumor cells. ALK belongs to the insulin receptor superfamily and plays an important role in nervous system development. ALK is not expressed in healthy adult human tissue but ALK dysregulation and gene rearrangements are associated with a variety of tumor cell types. NVL-655 is able to penetrate the blood-brain-barrier (BBB) and may therefore exert its activity against EGFR-driven central nervous system (CNS) primary tumors and CNS metastases.

Nefextinib is an orally bioavailable inhibitor of the fibroblast growth factor receptor (FGFR) and FMS-like tyrosine kinase 3 (FLT3; CD135; STK1; FLK2), with potential antineoplastic activity. Upon oral administration, nefextinib binds to and inhibits both FGFR and FLT3, including FLT3 mutant forms, which results in the inhibition of FGFR/FLT3-mediated signal transduction pathways. This inhibits proliferation in FGFR/FLT3-overexpressing tumor cells. FGFR, a family of receptor tyrosine kinases, is upregulated in many tumor cell types. FLT3, a class III receptor tyrosine kinase (RTK), is overexpressed or mutated in most B-lineage neoplasms and in acute myeloid leukemias. They both play key roles in cellular proliferation and survival.

Muvadenant is a small molecule drug. The usage of the INN stem ‘-adenant’ in the name indicates that Muvadenant is a adenosin receptor antagonist. Muvadenant has a monoisotopic molecular weight of 430.17 Da.
Adenosine is an ubiguitous modulator of numerous physiological activities, particularly within the cardiovascular, nervous and immune systems. Adenosine is related both structurally and metabolically to the bioactive nucleotides adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP) and cyclic adenosine monophosphate (cAMP), to the biochemical methylating agent S-adenosyl-L-methione (SAM) and structurally to the coenzymes NAD, FAD and coenzym A and to RNA.
Via cell surface receptors, adenosine modulates diverse physiological functions including induction of sedation, vasodilatation, suppression of cardiac rate and contractility, inhibition of platelet aggregability, stimulation of gluconeogenesis and inhibition of lipolysis. Studies show that adenosine is able to activate adenylate cyclases, open potassium channels, reduce flux through calcium channels, and inhibit or stimulate phosphoinositide turnover through receptor-mediated
mechanisms (Muller C. E. and Stein B., Current Pharmaceutical Design, 2: 501 , 1996; Muller C. E., Exp. Opin. Ther. Patents, 7(5): 419, 1997).
Adenosine receptors belong to the superfamily of G-protein-coupled receptors (GPCRs). Four major subtypes of adenosine receptors have been
pharmacologically, structurally and functionally characterized (Fredholm et al., Pharm. Rev., 46: 143-156, 1994) and referred to as A1, A2A, A2B and A3. Though the same adenosine receptor can couple to different G-proteins, adenosine A1 and A3 receptors usually couple to inhibitory G-proteins referred to as G, and Go which inhibit adenylate cyclase and down-regulate cellular cAMP levels. In contrast, the adenosine A2A and A2B receptors couple to stimulatory G-proteins referred to as Gs that activate adenylate cyclase and increase intracellular levels of cAMP (Linden J., Annu. Rev. Pharmacol. Toxicol., 41 : 775-87 2001).

Lunresertib is an investigational new drug that is being evaluated for the treatment of cancer. It is an oral small molecule inhibitor of PKMYT1, developed by Repare Therapeutics.[1] This drug targets cell cycle regulation in tumors with specific genetic alterations, including CCNE1 amplifications or FBXW7 and PPP2R1A loss of function mutations. It is currently in phase 1/2 clinical trials, both as monotherapy or in combination with camonsertib, an ATR inhibitor.[2]
Lunresertib is an orally bioavailable inhibitor of the human membrane-associated tyrosine– and threonine-specific cdc2-inhibitory kinase (PKMYT1), with potential antineoplastic activity. Upon oral administration, lunresertib targets, binds to and inhibits the activity of PKMYT1. This results in the inhibition of CDK1 phosphorylation, which may promote both premature mitosis and a prolonged mitotic arrest, and lead to the accumulation of unrepaired DNA damage and apoptosis in susceptible tumor cells, such as CCNE1-overexpressing tumor cells. PKMYT1 phosphorylates CDK1 specifically when CDK1 is complexed to cyclins, which blocks progression from G2 into mitosis.NCI Thesaurus (NCIt)

Lunbotinib is an orally bioavailable selective inhibitor of the proto-oncogene receptor tyrosine kinase rearranged during transfection (RET), with potential antineoplastic activity. Upon oral administration, lunbotinib selectively binds to various RET fusions and mutations, including solvent front resistance mutations, and inhibits the activity of RET. This results in an inhibition of cell growth of tumors that exhibit increased RET activity due to these fusions and mutations. RET overexpression, activating mutations, and fusions result in the upregulation and/or overactivation of RET tyrosine kinase activity in various cancer cell types. Dysregulated RET activity plays a key role in the development and progression of certain cancers. Lunbotinib is able to penetrate the blood-brain barrier (BBB) and may also be able to overcome resistance mechanisms to first generation selective RET inhibitors (SRIs).

Iodofalan (131I) is a radiopharmaceutical that has garnered significant attention in oncological research due to its targeted therapeutic potential. This compound, which includes the radioactive isotope Iodine-131, has been explored for its efficacy in treating certain types of cancers, particularly those associated with the thyroid. Various research institutions worldwide have been studying Iodofalan (131I) to better understand its clinical benefits, optimize its usage, and minimize potential side effects. As a drug type, Iodofalan (131I) is categorized as a targeted radiopharmaceutical therapy, which leverages the properties of radioactive isotopes to destroy cancer cells with precision. Currently, its primary indications include differentiated thyroid cancer and non-resectable metastatic thyroid cancer, among other investigational uses.
Iodofalan (131I) Mechanism of Action
The mechanism of action for Iodofalan (131I) centers on the properties of Iodine-131, a beta-emitting isotope. When administered, Iodofalan (131I) is selectively absorbed by thyroid cells. This selectivity is due to the thyroid gland’s natural ability to uptake iodine, a key element required for the production of thyroid hormones. Cancerous thyroid tissues retain this ability, making them ideal targets for Iodofalan (131I) therapy.
Once absorbed by the thyroid cancer cells, the radioactive decay of Iodine-131 begins. This decay process emits beta particles, which possess sufficient energy to destroy nearby cells. The radiation from these beta particles causes direct DNA damage, leading to cell death. Additionally, the gamma radiation emitted by Iodine-131 can be used diagnostically to track the distribution and uptake of the compound in the body via imaging techniques such as SPECT (Single Photon Emission Computed Tomography).
The dual role of Iodofalan (131I) in both treatment and diagnostic contexts underscores its importance in managing thyroid cancers. By delivering a localized radiation dose to thyroid cancer cells, Iodofalan (131I) minimizes damage to surrounding healthy tissues, which is a significant advantage over traditional external beam radiotherapy.
What is the indication of Iodofalan (131I)?
The primary indication for Iodofalan (131I) is the treatment of differentiated thyroid cancer, a category that includes papillary and follicular thyroid cancers. These subtypes are characterized by their ability to absorb iodine, making them particularly amenable to radioiodine therapy. Iodofalan (131I) is typically used in cases where the thyroid cancer is not amenable to surgical removal or has metastasized to other parts of the body. In such scenarios, the radiopharmaceutical offers a non-invasive therapeutic option that can target and destroy cancer cells even in distant metastatic sites.

Inlexisertib is an orally bioavailable inhibitor of the serine/threonine-protein kinase ULK 1 and 2, with potential antineoplastic activity. Upon oral administration, inlexisertib targets and binds to ULK1/2. This inhibits cancer autophagy, which mutant RAS cancer cells use for their survival, and results in tumor cell death. ULK1/2 mediates the autophagocytotic process and is often upregulated in cancers, especially in mutant RAS cancers. Autophagy plays a key role in a tumor cell proliferation and survival, and mediates tumor cell resistance.
