Merck-Moderna Cancer Vaccine Delivers Phase 3 Results
Catch Up
Merck and Moderna reported positive late-stage results for their personalized mRNA cancer vaccine in patients with high-risk melanoma. The Phase 3 study evaluated the vaccine alongside Merck's Keytruda following surgery.
What Happened
- The combination delivered statistically significant and clinically meaningful improvements in recurrence-free survival compared with Keytruda alone.
- The study also met its endpoint for reducing the risk of cancer spreading to distant parts of the body.
- The trial will continue to evaluate additional measures, including overall survival.
Why It Matters
The results represent an important validation for personalized mRNA cancer vaccines beyond their earlier-stage promise. For healthcare investors, continued clinical success could expand the role of mRNA technology into oncology while creating another potential growth opportunity within the rapidly evolving cancer treatment market.
Oil Falls as Hormuz Talks Raise Supply Hopes
Catch Up
Oil prices moved lower as discussions between Iran and Oman raised expectations that shipping through the Strait of Hormuz could begin to normalize. The development provided some relief to a market that has spent months pricing in elevated geopolitical and supply risk.
What Happened
- Brent crude fell more than 2% as investors responded to prospects for a temporary reopening of the Strait.
- Iran and Oman discussed measures aimed at restoring shipping through one of the world's most important energy routes.
- Markets remain sensitive to further developments, with normal oil flows through the region yet to be fully restored.
Why It Matters
The Strait of Hormuz remains critical to global energy markets, making progress toward restoring shipping potentially significant for oil supply, transportation costs, and inflation. While geopolitical uncertainty remains, improved energy flows could help ease some of the supply pressures that have supported higher crude prices
Canada-U.S. Trade Dispute Escalates
Catch Up
Canada-U.S. trade tensions intensified after negotiations failed to produce an agreement, triggering a new round of tariffs between the two countries. While recent clarification from Washington has eased one area of disagreement, broader trade talks remain stalled.
What Happened
- The U.S. imposed 50% tariffs on approximately US$20 billion of Canadian goods after negotiations broke down.
- Canada responded with plans for dollar-for-dollar retaliatory tariffs on U.S. imports, set to take effect September 8.
- U.S. officials have since clarified that Canada's policies supporting French-language content will not be targeted in future trade actions, removing one point of contention between the two sides.
Why It Matters
The immediate economic impact is concentrated on a relatively small portion of bilateral trade, but the bigger concern for investors is prolonged uncertainty. Canada and the U.S. have deeply integrated supply chains, and an extended dispute could weigh on business investment while creating additional risks for manufacturing, autos, steel, agriculture, and other cross-border industries.
