Consistent Phase III clinical trial advancement for VK2735

Previously, the topic was discussed in Q1 with detailed preparation and timelines ( " " ), in Q4 with an emphasis on initiating the trials in Q2 2025 and refining study design ( " " ), and in Q3 with a focus on preparing for and clarifying the trial protocol and timeline ( " " ).

In Q2, the discussion focused on the initiation of the Vanquish Phase III registration program with detailed patient enrollment and trial design updates ( " " " " ).

The narrative remains consistent but becomes more detailed and definitive in Q2, with clear indications that trial enrollment and design have advanced further compared to earlier periods. " " " " " " " "

Dual formulation strategy (subcutaneous and oral)

The dual formulation strategy was noted in Q1 with discussion on transitioning between subcutaneous and oral forms ( " " ), in Q4 with detailed study plans for both formulations and inclusion of an auto‐injector ( " " " ), and in Q3 as part of their overall strategy to complement the subcutaneous anchor with an oral option ( " " ).

In Q2, Viking reiterated the dual formulation strategy by detailing both the Vanquish Phase III subcutaneous trials and progress on the oral Phase II study ( " " ).

The emphasis on a dual formulation remains constant. Q2 highlights further progress by detailing enrollment data and extended trial designs, reinforcing its strategic importance. " " " " " " " " "

Uncertainty in dosing, titration, and transition strategies

In Q1, uncertainties were noted regarding finalizing doses, titration logistics, and transitioning between regimens ( " " " " ). Q4 discussions elaborated on detailed transition studies (e.g. weekly to monthly or subcutaneous to oral) with pending protocol specifics ( " " " " " " ), and Q3 reviews discussed complexities in dose escalation and transitioning (including auto‐injector use and monthly dosing concerns) ( " " " " " ).

In Q2, Viking discussed the dosing and titration approach for the Phase III Vanquish trials along with the complexities of transitioning to maintenance dosing ( " " " " " ).

While uncertainties about dose escalation and transitions have been a long‐standing theme, Q2 provides a more integrated and data‐driven approach, suggesting slight refinement and increased clarity on trial design despite remaining challenges. " " " " " " " " " "

Manufacturing agreements and supply chain challenges

Q1 provided details on long‐term, large‐scale manufacturing agreements and redundancy in supply chain ( " " " " " ); Q4 focused on the progress in finalizing manufacturing agreements and refining clinical material production timelines ( " " " ); Q3 emphasized current manufacturing capacity and ongoing discussions with global peptide suppliers ( " " " ).

In Q2, the focus was on announcing a comprehensive manufacturing agreement, which covers API and fill‐finish capacity, with no specific mention of supply chain challenges ( " ).

The evolution signals a consolidation from multifaceted discussions in earlier periods to a definitive agreement in Q2, signaling improved stability and fewer immediate supply chain concerns. " " " " " " " " "

Operational and logistical execution risks

Q1 discussed the challenges of preparing for Phase III—logistical tasks like dose labeling and site initiation were emphasized ( " " ), and Q4 mentioned narrowing study start dates due to logistical considerations ( " " ). Q3 provided hints of infrastructure expansion but did not directly address execution risks.

Q2 did not highlight operational or logistical risks explicitly.

The topic is no longer mentioned in Q2, suggesting that earlier execution risks may have been addressed or are now viewed as routine, leading to less emphasis on potential operational setbacks. " " " "

Financial strength and funding runway

In previous periods, Q1 noted a strong cash position with over $850 million ( " " ), Q4 reported a significant boost up to $903 million after a public offering ( " " ), and Q3 highlighted around $930 million in liquidity ( " " ).

Q2 reiterated robust financial strength with more than $800 million in cash, ensuring sufficient runway for Phase III and other programs ( " ).

Financial strength remains a consistent theme throughout all periods. Although the cash amounts vary slightly, all periods emphasize a robust funding runway that supports aggressive clinical development. " " " " " " "

Safety, tolerability, and efficacy data

Q1 showcased promising safety with both subcutaneous and oral formulations producing significant weight loss (up to 14.7% in Phase IIa and around 8% in Phase I) with mostly mild/moderate adverse events ( " " ). Q4 reinforced these data with similar weight loss percentages and predictable GI side effects ( " " " ). Q3 confirmed statistically significant reductions and a positive safety profile across obesity and NASH programs ( " " " ).

In Q2, detailed safety, tolerability, and efficacy data were reported for both formulations; the subcutaneous program demonstrated up to 14.7% weight loss and the oral program showed dose-dependent weight loss up to 8.2% with sustained effects ( " " " " ).

The consistently positive safety and efficacy profile is maintained across periods. Q2 builds on earlier data by providing confirmatory and more elaborate results, reinforcing confidence in clinical performance. " " " " " " " " " " "

Patient enrollment, demand, and market acceptance

Q1 described rapid enrollment in the Phase II tablet trial with strong market interest ( " " " ), while Q4 mentioned enrollment uncertainties and cautioned that timelines would only be clear post–site initiation ( " ), and Q3 did not specifically address enrollment or market feedback.

Q2 provided clear enrollment targets for the two Phase III trials (approximately 4,500 and 1,100 patients) and mentioned high interest and strong demand in both the subcutaneous and oral studies ( " " " " ).

Patient enrollment and demand have become more quantifiable and prominent in Q2 compared to earlier periods. The detailed figures underscore heightened market acceptance and improved investor confidence. " " " " " " " "

Regulatory uncertainties (including VK2809 for NASH)

Q1 made a brief mention of tariff-related regulatory uncertainties impacting future operations ( " ), Q4 discussed the end-of-Phase II meeting for VK2809 and acknowledged the complexity of Phase III trials due to biopsy requirements ( " " ), and Q3 mentioned receiving FDA feedback on VK2809 along with potential partnering considerations ( " " " ).

Q2 did not mention any regulatory uncertainties or updates regarding VK2809.

There is a noticeable de-emphasis in Q2 regarding regulatory uncertainties, suggesting that earlier concerns may have been resolved or are being managed more effectively, especially for VK2809. " " " " " "

Expansion into combination therapies and comorbid indications

In Q1, Viking discussed evaluating combination regimens and testing VK2735 in type 2 diabetes, along with early steps in the amylin agonist program ( " " " " ). Q4 detailed Phase III plans with parallel studies for obesity and obese diabetics and laid out IND plans for the amylin agonist ( " " " " ). Q3 added discussion on leveraging the amylin mechanism for combination effects ( " " " " ).

In Q2, Viking reiterated expansion into combination therapies by describing the dual study approach for obese patients with and without type 2 diabetes and advancing the amylin agonist program ( " " " " ).

The strategic focus on combination therapies and addressing comorbid indications has remained consistent, and Q2 further reinforces this with more detailed trial designs and clearer expansion into type 2 diabetes and amylin agonist initiatives. " " " " " " " " " " " " " " " "

Competitive landscape in obesity and diabetes treatments

Q1 provided a brief acknowledgment of high strategic interest in obesity ( " ), Q3 discussed competitor data from recent conferences and expressed confidence in Viking's positioning due to the quality of its programs ( " " ), and Q4 did not provide specific details.

In Q2, Viking addressed the competitive landscape by affirming that the market is large enough for multiple agents and reiterated confidence in their differentiated product offerings ( " ).

While competition is a constant backdrop, earlier calls (particularly Q3) analyzed competitor data more explicitly. Q2 maintains a confident tone, emphasizing that market size supports multiple players, with Viking staying focused on its unique attributes. " " " "
