Zolbetuximab (VYLOY™), a recombinant, chimeric, anti-claudin 18.2 (CLDN18.2) monoclonal antibody (mAb), is being developed by Astellas Pharma Inc. for the treatment of patients with HER2-negative (HER2^-), CLDN18.2-positive (CLDN18.2⁺) advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma and CLDN18.2⁺ advanced pancreatic adenocarcinoma. In March 2024, zolbetuximab was approved in Japan for the treatment of patients with HER2^-, CLDN18.2⁺ unresectable, advanced/recurrent gastric cancer (the gastric cancer indication includes GEJ cancer). Zolbetuximab is also undergoing regulatory review for HER2^-, CLDN18.2⁺ advanced gastric or GEJ adenocarcinoma in the USA, the EU, China, Australia and several other countries. This article summarizes the milestones in the development of zolbetuximab leading to this first approval for the treatment of patients with CLDN18.2⁺ gastrointestinal malignancies.

Mavorixafor (XOLREMDI™) is an oral, selective C-X-C chemokine receptor 4 (CXCR4) antagonist developed by X4 Pharmaceuticals that blocks the binding of C-X-C chemokine ligand 12 (also known as stromal derived factor-1) to CXCR4. In April 2024, it became the first therapy to be approved for WHIM syndrome (named by an acronym for its observed characteristics of Warts, Hypogammaglobulinaemia, Infections and Myelokathexis) in the USA, where it is indicated for use in patients aged ≥ 12 years with WHIM syndrome to increase the number of circulating mature neutrophils and lymphocytes. Clinical development of mavorixafor is ongoing for chronic neutropenic disorders. This article summarizes the milestones in the development of mavorixafor leading to this first approval for use in patients aged ≥ 12 years with WHIM syndrome to increase the number of circulating mature neutrophils and lymphocytes.

Background and objective: Although paracetamol (acetaminophen) combined with other analgesics can reduce pain intensity in some pain conditions, its effectiveness in managing low back pain and osteoarthritis is unclear. This systematic review investigated whether paracetamol combination therapy is more effective and safer than monotherapy or placebo in low back pain and osteoarthritis.

Methods: Online database searches were conducted for randomised trials that evaluated paracetamol combined with another analgesic compared to a placebo or the non-paracetamol ingredient in the combination (monotherapy) in low back pain and osteoarthritis. The primary outcome was a change in pain. Secondary outcomes were (serious) adverse events, changes in disability and quality of life. Follow-up was immediate (≤ 2 weeks), short (> 2 weeks but ≤ 3 months), intermediate (> 3 months but < 12 months) or long term (≥ 12 months). A random-effects meta-analysis was conducted. Risk of bias was assessed using the original Cochrane tool, and quality of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE).

Results: Twenty-two studies were included. Pain was reduced with oral paracetamol plus a non-steroidal anti-inflammatory drug (NSAID) at immediate term in low back pain (paracetamol plus ibuprofen vs ibuprofen [mean difference (MD) - 6.2, 95% confidence interval (CI) -10.4 to -2.0, moderate evidence]) and in osteoarthritis (paracetamol plus aceclofenac vs aceclofenac [MD - 4.7, 95% CI - 8.3 to - 1.2, moderate certainty evidence] and paracetamol plus etodolac vs etodolac [MD - 15.1, 95% CI - 18.5 to - 11.8; moderate certainty evidence]). Paracetamol plus oral tramadol reduced pain compared with placebo at intermediate term for low back pain (MD - 11.7, 95% CI - 19.2 to - 4.3; very low certainty evidence) and osteoarthritis (MD - 6.8, 95% CI - 12.7 to -0.9; moderate certainty evidence). Disability scores improved in half the comparisons. Quality of life was infrequently measured. All paracetamol plus NSAID combinations did not increase the risk of adverse events compared to NSAID monotherapy.

Conclusions: Low-to-moderate quality evidence supports the oral use of some paracetamol plus NSAID combinations for short-term pain relief with no increased risk of harm for low back pain and osteoarthritis compared to its non-paracetamol monotherapy comparator.

Despite swallowing being a frequently performed daily function, it is highly complex. For a safe swallow to occur, muscles within the head, neck, and thorax need to contract in a concerted pattern, controlled by several swallowing centers at multiple levels of the central nervous system, including the midbrain, cerebral cortex, and cerebellum in addition to five cranial nerves. Dysphagia, or difficulty swallowing, is caused by a long list of pathologic processes and diseases, which can interfere with various stages along the swallowing sensorimotor pathway. When present, dysphagia leads to increased mortality, morbidity, hospital length of stay, and reduced quality of life. Current dysphagia management approaches, such as altering the texture and consistency of foods and fluids and teaching patients rehabilitative exercises, have been broadly unchanged for many years and, in the case of texture modification, are of uncertain effectiveness. However, evidence is emerging in support of new medication-based and neuromodulatory treatment approaches. Regarding medication-based therapies, most research has focused on capsaicinoids, which studies have shown are able to improve swallowing in patients with post-stroke dysphagia. Separately, albeit convergently, in the field of neuromodulation, there is a growing and positive evidential base behind three non-invasive brain stimulation techniques: repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (TDCS), and pharyngeal electrical stimulation (PES). Should some or all of these emerging therapies fulfill their promise, dysphagia-related patient outcomes may be improved. This paper describes the current state of our understanding regarding new medication and neuromodulation-based neurogenic oropharyngeal dysphagia treatments.

Tarlatamab (tarlatamab-dlle: IMDELLTRA™) is a first-in-class, half-life extended bispecific delta-like ligand 3 (DLL3)-directed CD3 T-cell engager being developed by Amgen for the treatment of small cell lung cancer (SCLC) and neuroendocrine prostate cancer. Tarlatamab binds to DLL3 on the surface of tumour cells and CD3 on the surface of cytotoxic T lymphocytes (CTLs), resulting in T-cell activation, release of inflammatory cytokines and CTL-mediated cell death of DLL3-expressing tumour cells. In May 2024, tarlatamab received its first approval in the USA for the treatment of adults with extensive stage SCLC (ES-SCLC) with disease progression on or after platinum-based chemotherapy. Tarlatamab received accelerated approval for this indication based on overall response rate and duration of response in the pivotal phase 2 DeLLphi-301 study, and continued approval may be contingent on the demonstration of clinical benefit in a confirmatory trial(s). Tarlatamab is under regulatory review in Brazil, Canada, Israel and the UK, and clinical studies are underway in multiple countries. This article summarizes the milestones in the development of tarlatamab leading to this first approval for ES-SCLC with disease progression on or after platinum-based chemotherapy.

Tunlametinib (^®) is an oral, selective, mitogen-activated protein kinase kinase 1 and 2 (MEK 1/2) inhibitor being developed by Shanghai KeChow Pharma, Inc. for the treatment of solid tumours with RAS and RAF mutations, including melanoma, non-small cell cancer (NSCLC), colorectal cancer (CRC) and neurofibromatosis type 1 (NF1) plexiform neurofibromas. In March 2024, tunlametinib was granted conditional approval in China (based on surrogate endpoints) for use in patients with NRAS-mutated advanced melanoma who have failed anti-PD-1/PD-L1 treatment. This article summarizes the milestones in the development of tunlametinib leading to this first approval for the treatment of solid tumours with RAS and RAF mutations.

Tovorafenib (OJEMDA™) is a once-weekly oral, selective, brain-penetrant, type II RAF kinase inhibitor being developed by Day One Biopharmaceuticals, Inc., under a license from Takeda Oncology, for the treatment of paediatric low-grade glioma (pLGG) and solid tumours. Most pLGGs harbour alterations in the MAPK pathway, such as a BRAF mutation or BRAF fusion, which result in aberrant intracellular signalling. Tovorafenib is an inhibitor of mutant BRAF V600E, wild-type BRAF and wild-type CRAF kinases and BRAF fusions. In April 2024, tovorafenib received its first approval in the USA for the treatment of patients aged ≥ 6 months with relapsed or refractory pLGGs harbouring a BRAF fusion or rearrangement, or BRAF V600 mutation. It received accelerated approval for this indication based on the response rate and duration of response achieved in this population in the ongoing, pivotal, phase 2 FIREFLY-1 study. Clinical development of tovorafenib is underway in numerous countries worldwide. This article summarizes the milestones in the development of tovorafenib leading to this first approval for relapsed or refractory pLGG with an activating BRAF alteration.

Zastaprazan (JAQBO^®) is a next-generation potassium-competitive acid blocker being developed by Onconic Therapeutics, a subsidiary of Jeil Pharmaceutical, for the treatment of acid-related diseases. Zastaprazan binds directly to proton pumps in a competitive manner to reduce gastric acid secretion, allowing for a quick onset of action. On 24 April 2024, zastaprazan received approval in South Korea for the treatment of erosive gastroesophageal reflux disease (GERD). Zastaprazan is also undergoing phase III development for the treatment of gastric ulcer and for the prevention of non-steroidal anti-inflammatory drug (NSAID)-induced peptic ulcer. This article summarizes the milestones in the development of zastaprazan leading to this first approval for erosive GERD.
