Building the Momentum for A Stronger Pharmaceutical System in Africa.

Despite impressive progress, nearly two billion people worldwide have no access to essential medicines. The COVID-19 pandemic revealed Africa's vulnerability due to its reliance on imports for most vaccines, medicines, and other health product needs. The vaccine manufacturing is complex and requires massive financial investments, with global, regional, and national regulatory structures introducing consistent and urgent reforms to assure the quality and safety of medicines. In 2020, there were approximately 600 pharmaceutical manufacturers in Africa, 80% of which were concentrated in eight countries: Egypt, Algeria, Morocco, Tunisia, Nigeria, Ghana, Kenya, and South Africa. Only 4 countries had more than 50 manufacturers, while 22 countries had no local production. Out of the 600, around 25% were multinational companies. Africa is equally affected by modest scaled capacities substantially engaging in packaging and labelling, and occasionally fill and finish steps, facing criticalities in terms of solvent domestic markets. This article discusses the challenges in the development of a local pharmaceutical manufacturing in Africa and reflects on the importance of the momentum for strengthening the local medical production capacity in the continent as a critical opportunity for advancing universal health coverage (UHC).

Treatment of Patients With Metastatic Colorectal Cancer in a Real-World Scenario: Probability of Receiving Second and Further Lines of Therapy and Description of Clinical Benefit.

BACKGROUND: The optimal therapeutic strategy for metastatic colorectal cancer patients is still a matter of debate. There are no prognostic variables indicating how many lines individual patients ought to receive, and whether later lines could be effective even when earlier ones were not. PATIENTS AND METHODS: We retrospectively collected data from 420 consecutive patients with metastatic colorectal cancer at our institution, describing the proportion of patients who received second or later lines of therapy and the chance of a line of treatment being active when the previous line was not. For each line of treatment, we defined clinical benefit as the probability of not having had evidence of disease progression 6 months after the start of chemotherapy. RESULTS: Of the 373 patients with disease progression after first-line chemotherapy (1L), 277 received a second line (2L) (probability of being submitted to a 2L (P(2L)) = 74.3%): 143 (63.3%) of 226 received a 3L (P(3L)), and 56 (45.9%) of 122 were submitted to a 4L (P(4L)). Joint probabilities were: 2L 74.3%, 3L 47.0%, and 4L 21.6%. A total of 298 (71.5%) of 417 patients had a clinical benefit with 1L; 134 (48.6%) of 276 with 2L; 50 (35.2%) of 142 with 3L; and 12 (25.0%) of 48 with 4L. Taking all these data together, 31% of the patients who experienced early progression at 1L had the chance to have a clinical benefit with any further lines. CONCLUSION: Our study demonstrated that of 4 patients submitted to a 1L, about 3 will receive a 2L, about 2 a 3L, and nearly 1 a 4L. Later lines could be beneficial even though earlier ones were not.
