Too little, too late – lifesaving chemotherapy drugs for kids finally arrive at Eastern Cape hospitals
A month after the Eastern Cape Department of Health promised that they had paid the overdue bills that delayed the delivery of chemotherapy drugs to Nelson Mandela Bay hospitals and that the issue would be solved, crucial chemotherapy drugs finally started arriving at Port Elizabeth Provincial Hospital. But it was too late for some children, who have missed a cycle of treatment, leaving them at high risk. A month ago, the Eastern Cape Department of Health assured the public that it had paid the overdue bills for pediatric chemotherapy drugs and that the problem was solved. Only it wasn't. And medical teams were thrown into a race against time to prevent their little patients from defaulting on their treatment. Crucial chemotherapy drugs needed to treat five children, who have already missed a full cycle of treatment, only arrived at Port Elizabeth's Provincial Hospital on Thursday, 12 June. The five children were just the most serious of cases – many others also missed a day or two of treatment and newly diagnosed patients could not receive their initial treatment. The additional month's waiting could have devastating consequences for the patients. One pediatric oncologist, who works in another province, said they have seen cancer returning if a child misses a cycle of chemotherapy, and sometimes the returned disease will be resistant to first-line drugs. On 19 May, the department indicated that overdue bills, which were the reason for the outage, were paid and that drugs will be delivered. Documents from senior officials in the department that have been confirmed with three sources as authentic, however, show that on 21 May, doctors were warned that 11 types of chemotherapy were not available, and in four of these cases it was due to 'closed accounts'. It is understood that companies wanted a bigger part of their overdue bills paid after an initial payment was made. Carboplatin, one of the crucial chemotherapy drugs, was, however, reported to be out of stock with a contracted supplier and needed to be sourced from another supplier. On 2 June, outages were still not addressed and the hospital had no Betamethasone, no Carboplatin, no Dacarbazine, no Methotrexate, no Leucovorin, no Polygam – either 6 grams or 12 grams – no Melphalan and no Spironolactone. Pharmacies had received Vinblastine (two months of stock) and Vincristine (commonly given as an IV injection – six months of stock). For the next 10 days, patients needing chemotherapy drugs that were out of stock were sent away. Yesterday, on 11 June, an entire contingent of patients were again sent away – five of them have by now missed an entire cycle of chemotherapy or three weeks of treatment. The South African Human Rights Commission (SAHRC) has launched an investigation into the repeated interruptions of cancer treatment for public healthcare patients in the Eastern Cape. Dr Eileen Carter from the SAHRC said the Democratic Alliance (DA) had laid a complaint with them about the matter. The oncology units in Gqeberha previously ran out of chemotherapy medication in January after the Eastern Cape Department of Health's account with a supplier was suspended due to a delayed payment. At the time, the medicines that were in short supply were Docetaxel injection vials and Anastrozole tablets. On Sunday, Sizwe Kupelo, the spokesperson for the Eastern Cape MEC for Health Ntandokazi Capa, said the department 'wishes to reassure members of the public that drug availability in our facilities is one of the top priorities'. 'An amount of R284-million has been made available to pay pharmaceutical companies and order medicines. As of the past two weeks, R60-million was disbursed and various suppliers have already started deliveries. This week, orders and payments will continue to be made. To monitor progress, the head of the department, Dr Rolene Wagner, has established a task team led by a chief director to coordinate the whole ordering and delivery of medicines, with oncology being a priority. 'Pharmacists from all oncology departments in all three of our major hospitals also had a meeting with the HOD and pharmaceutical services in Bhisho to discuss their stock levels. We wish to re-emphasise that payment of service providers is no longer an issue at this stage and medicines are being delivered. 'However, we have been made aware that some companies that are on the national contracts do not have certain products available, due to global supply chain issues. 'To address this, the task team and relevant managers are liaising with the national department to seek permission to procure outside the contracted companies,' he said. This process appears to only have been started two weeks after the out-of-stock chemotherapy drugs crisis was confirmed. 'Once again, this is a priority to both the MEC and the HOD, and both offices will continue to monitor and provide support to colleagues on the ground,' Kupelo said. DM

Merck's WELIREG Entry Brings New Momentum to Pheochromocytomas and Paragangliomas Therapeutics Market
The FDA has granted a third approval for WELIREG, authorizing its use as a treatment for patients with rare endocrine system tumors known as pheochromocytoma or paraganglioma (PPGL). This approval applies to individuals aged 12 and older with locally advanced, unresectable, or metastatic PPGL, making WELIREG the first oral therapy available for advanced cases of the disease. LAS VEGAS, May 28, 2025 /PRNewswire/ -- Pheochromocytomas and paragangliomas (PCPG) are highly vascular neuroendocrine tumors originating from chromaffin cells of the adrenal medulla or from neural crest-derived cells located outside the adrenal glands. These tumors are categorized based on their location, either in the adrenal medulla or in extra-adrenal paraganglia. They arise from sympathetic tissues found in the adrenal glands or along the abdomen, or from parasympathetic tissues in areas such as the head, neck, and thorax. Sympathetic tumors often secrete large quantities of catecholamines and are found in the adrenal medulla in about 80% of cases. The remaining 20% are extra-adrenal, typically located along the prevertebral and paravertebral sympathetic ganglia in the chest, abdomen, or pelvis. In 2024, there were 4,900 incident PCPG cases across the 7MM, with numbers expected to rise in the coming years. Although significant progress has been made in understanding these tumors, accurately predicting their malignancy remains challenging in the absence of detectable metastases. Surgical resection remains the primary treatment for most localized PCPGs when feasible. In cases of advanced or metastatic disease, management typically involves symptom control using medications such as alpha-blockers, beta-blockers, and inhibitors of catecholamine synthesis to avoid serious complications. When surgery is not viable, treatment options include systemic chemotherapy with Cyclophosphamide, Vincristine, and Dacarbazine (CVD), as well as radiolabeled MIBG therapy (AZEDRA, which was approved in 2018 but discontinued in early 2024). However, the effectiveness of CVD in improving overall survival is unclear, as most patients eventually face disease progression and death. Learn more about the PCPG treatment @ New Treatment for Pheochromocytomas and Paragangliomas DEMSER (metyrosine) was authorized for use in the United States in 1979 to treat pheochromocytoma. This FDA-approved drug is indicated for preoperative preparation, treatment of patients who are not candidates for surgery, and long-term management of malignant pheochromocytoma. In January 2019, ONO gained approval in Japan to produce and sell DEMSER capsules aimed at controlling catecholamine excess in pheochromocytoma patients. Later, in July 2020, the US FDA approved the first generic version of DEMSER oral capsules, manufactured by Amneal Pharmaceuticals, marking the initial generic approval for DEMSER in the US. In May 2025, Merck announced that the FDA approved WELIREG, the company's oral inhibitor of hypoxia-inducible factor-2 alpha (HIF-2α), for treating adults and children aged 12 and older with locally advanced, inoperable, or metastatic pheochromocytoma or paraganglioma (PPGL). The approval was based on findings from the LITESPARK-015 clinical trial, a single-arm study in which the primary measure of efficacy was the objective response rate (ORR). The trial included 72 patients in a single group (Cohort A1) with measurable disease confirmed by blinded independent central review (BICR) per RECIST v1.1. All participants had a histopathological diagnosis of PPGL and either locally advanced or metastatic disease not suitable for surgical or curative treatment. Their blood pressure was adequately controlled (below 150/90 mm Hg for adults and below 135/85 mm Hg for adolescents) without recent changes in antihypertensive therapy. Patients with carcinomatous meningitis were excluded. Participants received WELIREG at 120 mg once daily until disease progression or the onset of unacceptable toxicity. The primary efficacy endpoint was ORR as assessed by BICR under RECIST v1.1 criteria. Secondary endpoints included duration of response and time to initial response. WELIREG's prescribing information includes a boxed warning noting that exposure during pregnancy may cause harm to the fetus. Healthcare providers are advised to confirm pregnancy status before starting treatment and to counsel patients on the importance of using effective non-hormonal contraception, as WELIREG can reduce the effectiveness of hormonal methods. Additionally, the drug may lead to severe anemia requiring blood transfusions and serious hypoxia, which could necessitate treatment discontinuation, supplemental oxygen, or hospitalization. Regular monitoring for anemia is recommended before and during therapy. Find out more on FDA-approved PCPG drugs @ Pheochromocytomas and Paragangliomas Treatment Options Ongoing clinical trials are assessing a range of targeted therapies aimed at improving treatment outcomes for PCPG. These include radionuclide therapies using SSTR2 agonists and antagonists, alpha-emitting agents, and SSTR2 analogs. Other approaches under investigation involve Dopamine Receptor D2 (DRD2) modulators and ClpP agonists. Each therapy employs distinct mechanisms of action, offering promising advantages and making them key candidates in the advancing PCPG therapeutic landscape. Radionuclide therapy works by delivering radiolabeled peptides to tumor cells via specific receptor targeting. Current clinical guidelines suggest that radioligand therapy may serve as a suitable first-line treatment for patients with slowly to moderately progressive metastatic PCPG, provided the tumor demonstrates uptake of the relevant radioisotope. Several prominent institutions, including the National Cancer Institute (NCI), M.D. Anderson Cancer Center, Gustave Roussy Cancer Campus, and Columbia University are actively conducting clinical studies in this area. Discover which therapies are expected to grab major PCPG market share @ Pheochromocytomas and Paragangliomas Market Report Some of the drugs in the pipeline include ONC201 (Jazz Pharmaceuticals/Chimerix), [212Pb]VMT-α-NET (Perspective Therapeutics), and LUTATHERA (Lutetium [177Lu] oxodotreotide/dotatate) (Novartis), among others. ONC201, also known as dordaviprone, is a first-in-class small-molecule imipridone that specifically targets the G-protein-coupled receptor DRD2 and the mitochondrial protease ClpP. It was investigated in a Phase II, open-label, investigator-initiated trial at the Cleveland Clinic, involving 30 patients with rare neuroendocrine tumors. Interim results demonstrated a 50% overall response rate (ORR) in paraganglioma cases with dopamine-secreting tumors located outside the brain. These findings, based on investigator assessments, were presented at the 2021 ASCO Annual Meeting and later published in Clinical Cancer Research in 2022. [212Pb] VMT-α-NET is a Targeted Alpha Therapy (TAT) radiopharmaceutical in clinical development for diagnosing and treating SSTR2-positive neuroendocrine tumors, a challenging and uncommon cancer type. Perspective Therapeutics is conducting a multicenter, open-label Phase I/IIa dose-escalation and expansion trial (NCT05636618) in patients with unresectable or metastatic SSTR2-expressing tumors who have not previously received peptide receptor radionuclide therapy. The FDA has granted Fast Track Designation (FTD) for this program based on encouraging preclinical data, regardless of patients' prior treatment history. As of February 2025, 30 patients have been enrolled in Cohort 2, with regulatory alignment pending for Cohort 3. In April 2025, Perspective Therapeutics announced that data from both the [212Pb] VMT-α-NET and [212Pb] VMT01 programs had been accepted for presentation at the upcoming ASCO Annual Meeting, scheduled for May 30–June 3, 2025, in Chicago, Illinois. Details for regular abstracts are expected to be released on May 22, 2025, at 5:00 PM EDT.
